What are the paper markings and what do they mean –

What affects paper quality?

First of all, the paper used affects the device in which it is used (printer, MFP), it is very important to select consumables in accordance with the requirements of the device.

Rough and hard paper will cause wear on the pick roller. It is more difficult for the roller to grip paper with a non-uniform surface and hard paper, as a result, the rubber coating wears off, and in the future the roller will not be able to cope even with high-quality paper. This moment does not come immediately; it depends on the frequency of use and the amount of paper passed through the printer.

The quality of paper affects the absorption of ink in inkjet printers and MFPs. When printing inside the printer, ink is sprayed onto the paper. Paper made from low-quality raw materials absorbs 80-90% of the ink, the remaining 10-20% settles on important components of the device.

In a laser printer, the choice of paper directly affects the image drum. The coating on the drum is very sensitive and the rough surface of the paper will wear it off over time. Repair and replacement are possible only at a service center. In addition, economy class paper leaves lint on the surface of the photodrum and cartridge; the lint clogs important parts of the printer and contaminates the contacts.

The appearance of the printed document, the readability of the text, and the saturation of the print also depend on the proper selection of paper.

Whiteness and brightness of paper

Many people take these indicators as one, but this is not entirely true.

Paper whiteness is an optical property indicated by the color of paper, close to white.

Paper brightness – determines the amount of reflected light on the surface of the paper.

Each of the characteristics has its own standard in different systems. I SO is a European standard regulating the whiteness of paper. C IE – responsible for brightness indicators.

According to the standards, there is a certain distinction in quality:

A grade is a rare type of paper due to its high cost and highest quality parameters. The price is explained by the raw material, which is eucalyptus. It is this type of raw material that allows us to achieve high whiteness values ​​of ISO 98% and brightness CIE 161%.

Representative documents are the face of the company, class A paper will not only preserve them for many years, but will also accurately reflect the color and contrast of the print.

B class – the optimal choice for high-speed and two-sided printing. The price is more than justified, only 10-15% higher than the most consumed and widespread class C. Characterized by high density, whiteness (ISO 97 – 98%)

C class is the most common class of paper on the Russian market, attracting with its low cost. However, this class should be chosen only for small batches and circulations. Best use: small offices, educational institutions, home printing.

Whiteness (ISO 92 – 94%) and brightness (CIE 135 – 146%) indicators are inferior to classes A and B, but this is not the only thing that distinguishes the budget version of consumables. Class C paper is often rough, sometimes with patches of lint. Therefore, use in industrial and frequently used devices will have a detrimental effect on the operation of the device.

Not long ago, intermediate classes of office paper appeared: A, B, C. One of the characteristics does not reach a higher class, while the remaining indicators correspond to a class an order of magnitude higher.

Types of paper

There are several types of paper and each of them has a different density to best suit the task. There are varieties such as:

  • offset – the thinnest, and, accordingly, the most inexpensive paper;
  • coated – divided, in turn, into glossy and matte varieties;
  • self-adhesive paper;
  • cardboard is the densest, and therefore the most expensive type of paper.

Each type of paper, different in its density, is suitable for specific purposes, for example:

  1. Paper with a density of 35 g/m 2
    up to 70 g/m 2
    Used for printing budget leaflets, low-cost advertisements, as well as receipt rolls and standard newspapers.
  2. 80 gm 2
    – This is the thickness of standard paper for office use.
  3. The density of coated paper (chalk) starts from 90 g/m 2
    .
  4. On paper up to 115 gsm 2
    Print inexpensive leaflets and various booklets. There is also office paper of this thickness, usually used when printing important documents or forms.
  5. Paper with a density of 130 g/m 2
    up to 150 g/m 2
    used for making photographs, high-quality advertising brochures, and publishing magazines.
  6. Paper whose weight is 170 g/m 2
    has found application in the field of preparing wall calendars, as well as for printing magazines, catalogs and price tags. It can also be used when printing on a laser printer.
  7. 200gsm paper 2
    , that is, having a high density, is suitable for printing invitations, book inserts, high-quality booklets and some price tags.
  8. For the production of gift cards and postcards, it is customary to use coated paper with a density of 250 g/m 2
    . Designer paper used for product personalization has the same thickness.
  9. Paper whose weight is 300 g/m 2
    (this can be either chalk or cardboard), used to create magazine covers, high-quality catalogs and price tags.
  10. When asking what paper weight is required for business cards, the figures of 250-300 g/m 2 apply
    .

Humidity

Humidity levels affect the final print result. Paper with high humidity curls, becomes deformed, and toner or ink falls off more often. To maintain humidity values ​​within normal limits (4-7%), paper should be stored in packaging at a temperature of 10 – 30 C.

Hardness

An important characteristic that affects the likelihood of a sheet jam in office equipment. The stiffer the sheet, the easier it will pass through the printer’s rollers.

I’ll conduct an experiment: how a sheet of one or another brand of paper will behave when hanging from the edge of a table.

Photo 15. Measuring the hardness of A4 class C paper. The difference is noticeable.

Photo 16. From a different angle. Since you need to compare relative to other papers, it is not so easy to show in one photo.

Here are the results:

The hardest SvetoCopy A4 Paper – 5 points

XEROX PERFORMER A4 paper and BALLET UNIVERSAL A4 paper – 4 points

HP HOME&OFFICE A4 paper sagged the most – 3 points

How does paper thickness affect graphic work?

Printing various publications and creating branded products are not the only uses for paper. In the case of professional graphic work – drawings, drawings and sketches – you cannot do without special paper.

The use of Whatman paper is popular and practical. What is Whatman paper and what is the thickness of this type of paper? Whatman paper is high-quality white paper, thick, without a pronounced texture. Used for both educational and production graphics.

Paper used for graphic work is:

  • rough (uncoated),
  • matte.

So, how thick should paper be for drawing?

First of all, in the case of drawings, it is better to choose matte Whatman paper, which not only absorbs ink well, but also adequately conveys the color palette. When printing a product on a plotter, it is allowed to use whatman paper or special uncoated paper – for example, for test or training drawings.

Summarizing what to look for when buying drawing paper, we can note the white color and density of 80-200 g/m2. For printing, you can use less dense options 80-150 g/m2. For manual drawings, it is advisable to prefer whatman paper with a density of 200 g/m2.

Paper grade “a”

The technical characteristics of paper with this marking are considered excellent. Typically, this paper is used for high-quality printing. It fits

  • business correspondence,
  • important documents;
  • documents printed for management.

The quality of printing on such paper will be guaranteed to be high (provided the printer is in full working order). Working with such paper is recommended if you care about office equipment: it works best with class A paper.

Paper grade “b”

Golden mean. This is optimal paper with technical characteristics slightly lower than A-class paper. However, the price of B-class paper is lower. It is suitable for almost any technique, excluding the most sensitive ones.

Paper grade “c”

The most economical option, however, the technical indicators of this paper are minimal. If there are no special requirements for print quality or you need to make many copies of one document, you can use grade C paper.

Using high-quality office paper helps to save on equipment maintenance, since the main cause of breakdowns is usually contamination and the accumulation of paper dust.

If you want to determine the whiteness of office paper, you need to refer to the international standards ISO and CIE. Pay attention to the percentages for these indicators: the higher they are, the whiter the sheet. For example, the values ​​could be: CIE 146% and ISO 94%.

To keep paper in usable condition for longer, avoid storing it in humid areas. It should be in rooms with a normal, comfortable temperature for humans.

Number of sheets in a pack

White paper
– an obvious standard in office printing. However, colored paper is also popular.

Yellow paper
– actively used for printing important announcements. Other light shades are used for the same purposes: blue, green, orange, pink.

Dark colors are much worse for printing: purple, red, blue. Manufacturers even have black office paper in their arsenal. You need to print on it with “metallics” – silver or gold paint, which is not available in a regular printer.

International Paper Standards

ISO 216:1975 is considered the universal international system of standards for determining paper sizes. The principle of standardization here is simple: the ratio of the width and length of the sheet is identical to the ratio of the side and diagonal of the square. Most models of modern printing equipment work with paper formats according to ISO 216.

The standard system is metric. This allows absolute sheet length/width values ​​to be rounded into standard units. The international standard provides for dimensions in millimeters. As mentioned above, the most famous and widely used format in ISO 216 is the A series format. It is actively used in the EU, Russia and a number of other countries.

About office paper and its use

MARKET PARTICIPANTS > Office paper

Plain office paper A4/A3 80 g/m 2
divided into 3 classes:

  • Class C.
    Whiteness about 145 CIE.
    It can be used without problems in black-and-white copiers and printers with print/copy speeds of up to 35 pages per minute in single-sided print/copy mode. This office paper is not suitable for color copiers and printers. Not recommended for inkjet printers.
  • Class B.
    Whiteness about 160 CIE.
    It can be used without problems in black-and-white copiers and printers with print/copy speeds of up to 180 pages per minute in duplex printing/copying mode. This office paper provides acceptable mono printing quality on an inkjet printer.
  • Class A.
    Whiteness from 165 CIE.
    It can be used without problems in black-and-white and color copiers and laser and inkjet printers at any print speed, except for printing/copying photographs.

The classification system for office papers in Russia and Europe is slightly different.
Our class B corresponds to European C, and our B corresponds to European B. Thus, DataCopy paper in Russia is positioned as class A office paper, but in Europe it belongs to class B.

Lately, the line between Class C and Class B has become blurred. Ultimately, this will result in only two classes of office paper remaining: everyday office paper and premium office paper.

This is much more understandable for the office paper consumer.

Format
office paper is the size of its sheet. The format is usually measured in millimeters (mm), less often in centimeters (cm). The most common A4 office paper size is 210 x 297 mm. The A3 office paper format is twice as large in area, and the size of one of the sides is the same as in A4, and the other is 2 times larger: 420 x 297 mm. A3 paper is not suitable for all office equipment. When purchasing a copy machine and/or printer, you need to look at the Specifications section in the Instructions to find out whether this office equipment can work with A3 paper. A3 paper is used much less frequently in office work than A4 paper.

Sometimes you can still find writing paper in the Soviet C11 format: 203 x288 mm. It is slightly smaller than A4 format.

Finally, for office devices there is A3 paper. This size is slightly larger than A3, namely: 329 x 483 mm.

Other paper sizes are not considered office paper. Although these formats may be present in office equipment. For example, many printers and copiers are designed to work on formats smaller than A4. In particular, many office inkjet printers are capable of working on 100 x 150 mm photo formats and even printing on CDs.

  • Portrait (portrait)
    The orientation of office paper is that the larger side of the paper is vertical and the smaller side is horizontal.
  • Landscape (landscape)
    The orientation of office paper is, on the contrary, when the larger side is horizontal and the smaller side is vertical.

Paper weight
is the weight of a sheet of paper per unit area. Typically, paper density is measured in grams per square meter. If you are told that the paper has a weight of 120 g/m 2
, this means that a sheet of this paper with an area of ​​1 square meter will weigh 120 grams. Very often, buyers confuse paper density and thickness. In their delusion, they try to determine its density by feeling. This is why many buyers want to feel the paper when purchasing paper.

The standard density of office paper is 80 grams per square meter. Any office equipment should work with office paper of this thickness. Why did the standard paper density become exactly this density of 80 g/m 2
, and not another? This standard was set by Xerox after Xerox invented the copier.

Dot matrix printers and typewriters can work with office paper of lower density, approximately 60-65 g/m 2
. This type of paper is often called writing paper. Its low density is due to the ability to work with carbon paper and print up to five copies at once. Laser and inkjet printers, as well as copiers, do not guarantee work with office paper of such low density.

Printers and copiers can handle office paper heavier than 80 gsm 2
. Before buying office paper of a higher density, you need to look at the instructions for your printer and/or copier and see what maximum density of office paper your office equipment can work with.

Main densities of office papers – 65, 80, 100, 120, 160, 200, 220, 250 and 280 g/m 2
.

Thickness
office paper is usually measured in microns (µm), that is, thousandths of a millimeter. The thickness of the paper, generally speaking, is not strictly tied to the density of the paper. Therefore, customers often believe that different standard 80gsm office papers may feel different to the touch. In fact, it is not the density of office paper that is determined by touch, but its thickness. Therefore, all the talk about some office paper manufacturers not being able to withstand the density of 80 g/m 2
can only be done if the stack of paper is weighed on a scale. It is easy to calculate that a sheet of A4 office paper with a density of exactly 80 g/m 2
should weigh 4.9896 g, and the entire pack (without packaging) of 500 sheets should weigh approximately 2 kg 495 g. If, when weighed, a smaller number is obtained, then, indeed, the declared standard density is not maintained.

Thickness of different brands of office paper of the same density 80 g/m 2
You can compare by placing two stacks of five packs of two different brands of paper on the table. This will be exactly 2500 sheets in each stack. And a significant difference in the height of the stacks will indicate a significant difference in thickness.

At the same density, the thicker the paper, the more loose and porous it is. This is not always good for inkjet printers if the ink is not pigment based, but water based. The thinner the paper at the same density, the more compressed it is.

If we consider not different brands of office paper, but the same brand, then the higher the density of the paper, the greater its thickness. There is usually a direct relationship between the density of the paper and its thickness.

Manufacturers of office paper do not believe that paper thickness affects the paper’s passage through office equipment and therefore generally do not list the thickness of their paper in the specifications list. It is believed that the paper density affects the passage of office paper through a copier or printer. The thickness of office paper of the same brand may vary slightly from one batch to another. Which may also be the reason for various rumors about defects or piracy in the production of office paper.

Another myth that exists among buyers of office paper. Sheet thickness is often confused with sheet elasticity. The thickness of a sheet of paper is a strict objective value that can be measured with instruments. But there is no objective concept of paper elasticity. Let’s start with the fact that paper, unlike most metals and other materials, has strong plastic properties. Pinch any paper at the fold and straighten it again. There was a trace of bending on the sheet and the sheet did not take its original shape. The larger the fold, the less elastic the paper becomes. Further, the elasticity of the paper depends on the size across the fold. Purely subjectively, a business card seems more elastic than a sheet of A3 paper. Some sellers use this and, as a sample of paper, give the buyer to touch a piece of paper the size of a business card or even smaller, so that subjectively the buyer seems this paper stiffer, and therefore thicker.

Whiteness
– this characteristic of paper, which shows how close the color of a sheet of paper is to white. This characteristic greatly affects the consumer properties of paper. The buyer wants to have paper as white as possible, even when he does not need color printing at all, where it is really important to have paper of increased whiteness. Considerations of image and prestige come into play here.

Due to the fact that there is no objective definition of white from a physical point of view, several different scales for measuring paper whiteness are used around the world. The most common two measurement systems. The first system is a system of measuring whiteness as a percentage, where 100% means the ideal white color, which in practice is never achieved. The second system is called the CIE system.

As you know, paper is made from cellulose, which in turn is made from wood. Therefore, the natural color of the paper should be the color of the wood when freshly cut. To make paper white, it is made using complex technologies of chemical bleaching (often with chlorine) and physical bleaching by adding ordinary chalk. All paper manufacturers have their own bleaching secrets. The whitest papers can reach 98% whiteness. A 1%-2% difference in paper whiteness is almost invisible to the eye. The color of the paper changes much more strongly and noticeably depending on the lighting: sunny, cloudy, incandescent or fluorescent.

For small-run production of business cards in offices and apartments, high-density office paper is used. Typically this is paper with a density of 200 g/m to 300 g/m. Either office paper is used for laser printers and copiers if business cards are printed on a black and white or color laser printer or on an inkjet printer without full color. For inkjet full color, inkjet photo paper or microporous photo paper is used.

Other A3/A4 format materials are also used on office printers and copiers.

These are, first of all, transparent films for projection devices for presentations, tracing paper for pressing the original layout for offset printing, thermal transfer paper for transferring images to fabric and designer art paper for simulating painting.

Paper in rolls with a width of 210 mm to 420 mm is used mainly on dot matrix printers. Moreover, such paper comes with both side perforation (holes on the sides) and without perforation. The paper itself in such rolls (rollers) usually resembles writing paper with a density of 60-70 g/m2.

Rolled paper of long length, which needs to be torn into identical sheets after printing, is often not rolled into a roller, but accordion-folded onto sheets of A4 or A3 format. To make it easier to tear the paper tape into separate sheets, small perforations are made along the folds of such paper.

Some inkjet printers have the ability to work with roll photo paper.

Older fax machines use fax paper rolls, which are thermal paper. This thermal paper turns black where it is heated. Special thermal heads are heated in the right places under the influence of electric current and the image is applied to the fax paper.

A similar printing mechanism works in new cash registers and prints on receipt paper (cash tape). The receipt paper of modern cash registers is also thermal paper.

Plotters use both wide-format roll paper and large-format sheet paper: A0, A1 and A2.

Many people find it tempting to use printing papers for offset printing in office equipment, for example, glossy, coated, embossed and designer. But this is not always possible. Firstly, offset paper must be cut into a format suitable for office equipment. Secondly, offset paper is primarily non-absorbent paper. It is designed for offset ink, which is not absorbed into the paper, but dries quickly on its surface.

Uniformity

The more uniform the paper structure, the better the printing level. Areas of uneven distribution of fibers perceive ink worse, and text, and especially the image, in such places will be of poor quality.

In an office setting, I will check the opacity by holding the sheets of paper to a light source.

Table 1. Results of weighing and measuring the density of grade C paper.  

A little mathematics: The density of paper is the weight of 1 sq/m2. A square meter of A4 paper is 16 sheets. Area A0 = 1m2 = 2A1=4A2=8A3=16A4. Therefore, 16 A4 sheets should weigh 80 g, and 1 sheet should weigh 5 g. There are 500 sheets of paper in a pack, which means that without packaging it should weigh 2500 g, and the weighing was carried out with packaging.

As we can see, the weight of the packs varies significantly. This indicates that the number of sheets is not the same (who will undertake to count?), or the paper density is not 80 g/m2.

I’ll find out about the density by weighing 1 m2 of paper (16 sheets) – will we get 80g?

Photo 7, 8. Density measurement of SvetoCopy and BALLET UNIVERSAL.

Photo 9, 10. Density measurement of HP HOME&OFFICE and XEROX PERFORMER.

The numbers speak for themselves: in class C only BALLET UNIVERSAL paper corresponds to reality, other representatives have a density lower than 80 g/m2.

Table 2. Results of measuring the thickness of a sheet of paper class C. It turns out that the sheet of paper is uneven in thickness, and the measurements of a representative of one of the brands differ significantly from the declared ones. Video 1. Measuring the thickness of a sheet of SvetoCopy A4 paper. Format

This is the main parameter that determines the choice of office paper. It depends on the capabilities of the printer, because the printer is physically unable to print on larger media. A4

– the most popular format on which the vast majority of office and home equipment prints. The physical dimensions of the sheet are 210×297 mm;

A3

– also a fairly common paper format for printers. Sheet size – 297×420 mm;

SRA3

– literally means “additional raw A3 format”. It is called raw because it is intended for further pruning. But if a regular raw A3 has dimensions of 305×430 mm, then an additional raw one has dimensions of 320×450 mm. This format is used for borderless printing – the printer initially prints on a slightly larger sheet, which is then trimmed. The result is beautiful products with 100% coverage of the sheet of paper. This format is used in printing houses that produce advertising and presentation products. SRA3 paper is usually of premium quality, with high whiteness and brightness;

Roll

– the name speaks for itself. A reel of paper is fed into the printer and used as needed. Cutting is done with knives built into the printing device. Roll paper is used for printing drawings, diagrams, design documentation, advertising and other presentation products of non-standard size.

 Some types of rolling paper repeat the structure of the canvas on which paintings are painted, so they are readily used for printing photographic pictures.

Paper size a1 and a0

A1 (594×841 mm) and A0 (841×1189 mm) paper is used for printing drawings, technical documents on design projects and other engineering documentation.

Such formats are also used in large-format advertising printing, which can be placed both indoors and outdoors.

Paper size a2

A2 format (420×594 mm) is widely used in advertising. It is perfect for printing various marketing materials intended for placement on walls in offices, administrative centers, sales areas, etc. The format is also used for printing lecture posters.

Paper size a3

A huge amount of printing is printed on A3 paper (297×420 mm): from wall calendars and posters to a school schedule, which is usually placed at home above the study table, and various diagrams, tables, diagrams, drawings, small maps.

Design development for such products is usually offered by Moscow printing houses as a separate service.

Paper size a4

Many people become familiar with A4 paper (210×297 mm) in childhood. It is this format that is used in the vast majority of cases for the production of sketchbooks. A4 paper is indispensable in the office. We regularly see it in printers, copy machines, and MFPs.

Also, forms for various applications, questionnaires, reports, presentations, contracts, etc. are printed on A4 sheets. Many catalogues, magazines and other periodicals also have this format.

Paper size a5

A5 paper (148×210 mm) is widely used in printing houses and print shops. Most leaflets and greeting cards have this format. Various forms, information cards, memos and much more are also printed on A5 paper.

Booklet formats

A booklet (usually advertising and informational) is one of the most relevant types of printed products. The sheet edition is made from different paper formats. The most common are A5, A6, A4.

The booklet, as a rule, provides for folds. A product printed in A6 or A5 format is usually folded in half. A4 format allows you to make more than one fold in different techniques: “zigzag”, “window”, “two parallels”, etc.

A series paper sizes

The A series paper format, which includes more than 10 sizes (A0, A1, A2, A3, A4, A5, etc.), is known to every person, even those not associated with the printing industry. This is the most used dimensional grid, according to which the length of any sheet is equal to its width multiplied by the square root of 2. All paper sizes of this format are based on an A0 sheet with an area of ​​1 m².

Series B and C paper sizes

There is another widely used series in the standardization system – B. It is used in cases where A-size paper is not suitable or when using it a large amount of waste is generated. Dimensions B are between two adjacent corresponding dimensions of series A.

Also included in international standardization is the C series. It most often designates envelope formats for correspondence. Dimensions C are located between the corresponding dimensions B and A. Thus, A4 paper easily fits in C4 envelopes.

Business card formats

Business cards are another type of printing product where sheet size is of particular importance. In Russia, the standard format most often used is 50×90 mm.

However, business cards can be smaller in size. For example, in the international business environment it is customary to use cards of 85.6×53.98 mm, according to the ISO 7810 ID-1 standard.

Business cards of 85×55 mm are considered standard for EU countries. The American standard requires the use of cards measuring 88.9×50.8 mm. And in Japan, all business card holders and organizers are designed for paper or plastic 91×55 mm.

Printing formats and sizes

The printing industry involves the use of a wide variety of paper types, formats and series. Sometimes the dimensions of a product are strictly regulated. In other cases, they are determined by the customer of the services. Let’s look at a few examples that will help you better understand paper formats and standards.

Leaflet formats

Advertising leaflets can also come in different sizes. The most common 4 types:

  • A5 (148×210 mm)
  • A6 (105×148 mm)
  • A7 (74×105 mm)
  • A4 (210×297 mm)

A5 format is universal. The sheet area is sufficient for posting information about the company, promotions, special offers for customers, etc. A4 leaflets are used to promote products that require detailed explanation. Most often we see them in banks, insurance companies, car dealerships, etc.

Leaflets in A7 and A6 formats are practical and, when executed skillfully, perfectly convey the very essence of advertising. They make it possible to place a succinct and precise proposal. The size of the sheet makes it easy to put the leaflet in your pocket. The costs of producing such products pleasantly surprise customers.

Leaflet formats

In addition to booklets, leaflets are actively used in advertising. In fact, this is nothing more than a Euro version of the classic booklet. The leaflet is usually printed on A4 paper and has two or more folds.

The final format of the product is determined by the wishes of the customer. The most common options: 100×210 mm, 98×210 mm, 90×210 mm.

Let’s summarize

So, the first thing when buying office paper is to rely on the characteristics recommended for the printing device. Then determine what purpose the consumable should serve.

Universal option: standard A4 paper, with a density not exceeding 100 g/m2, a large number of sheets in a pack.

Option for printing representative documents, leaflets, booklets: A3 and A4 formats, but density above 100 g/m2, as a rule, produced in large packs.

To print business cards, booklets, art leaflets, you must choose high-density paper from 200 g/m2, coated (often packed in 50-100 sheets).
