Photo formats for printing: overview of main sizes

What are minilabs?###

In modern photo laboratories, the bulk of photographs are printed on special machines called minilabs. This equipment is focused on printing small and medium formats – usually from 10 x 15 to 30 x 90 cm inclusive. The peculiarity of minilabs is the optimization of processes for mass photo printing of standard (not arbitrary) formats.

Using a special laser or LED head, the image from the RGB graphic file is exposed on photo paper with a photosensitive emulsion, then the print goes through the classic “wet” process. Modern minilabs, combined with technologies for working over a local network, make it possible to print 1000-1800 digital prints of 10 x 15 per hour or more.

When printing from photographic film, the negative or slide is scanned with a special built-in scanner, then work with the image is done in the same way as with a regular file. In small laboratories, where stopping production is not too critical for the business, there is usually one machine. In medium and large laboratories, less than 2-3 high-performance minilabs are rarely installed.

The photo printing operator makes color correction.

Over the past few years, the market for minilab manufacturers has narrowed to two giants – Noritsu and Fuji. According to unofficial data, at this time attempts were made to unite the relevant divisions into a single corporation, but the Antimonopoly Committee of Japan did not allow this.

As a result, today both companies produce almost identical minilabs, but under different logos. All other minilab manufacturers have ceased operations. Recently, Chinese manufacturers, in particular Sophia, have begun to appear on the market.

Despite the fact that their minilabs actually copy Noritsu, the quality of these machines leaves much to be desired, so such machines are used mainly in laboratories without any significant requirements for print quality. Apparently, the share of such machines in the world is still insignificant.

In addition to minilabs, there are printing machines for large formats. The leader of “large format” in our time is the Italian manufacturer Durst. In general, the printing technologies on these machines are the same as on minilabs. The main differences are the possible print formats, resolution and color gamut, which tends to be slightly higher for larger machines.

11 questions about digital photo printing (part one)

Envelopes with printed photographs.

Digital photography allows you to view the results of your shooting directly on your computer, so today we print much less often than in film days. However, precisely because of the “exclusivity” of the task, the requirements for the quality of hard copies also increase: having spent time selecting and processing the best photographs, we expect to see an equally high-quality result on paper.

    . I don’t know what’s going on here. And more. But the detail will become deeper, plus scratches and fingerprints on this type of paper are almost invisible.
  • Branded photo paper
    . When printing photographs, it is best to use paper specifically designed for this task. Moreover, top manufacturers of office equipment (the same Epson and Canon) produce material specifically for their printers. This type of photo paper is called branded. The manufacturer takes into account all the technical nuances of its devices to ensure that the quality of the printed image is the highest.
  • All-purpose photo paper
    . It is produced by third-party companies, supposedly to be compatible with any printer models. However, this may not work. Before purchasing paper, check in the printer manual to see what types and formats are supported. Otherwise, the quality of the photo may turn out to be low, or the sheet may remain white.
  • Regular
    . No one has canceled ordinary printer paper. However, this is absolutely a backup option. The source file must have very good quality and resolution in order to look decent on plain paper. And the long-term safety of such a printout is highly doubtful.

What type of printer to use

  • Inkjet
    . This is the most common type of printing device. Among the advantages are an affordable price and high image detail. However, consumables – cartridges – quickly run out or dry out, and they have to be changed frequently. In addition to photographs, inkjet printers are suitable for printing documents on paper of all available formats.
  • Laser
    . Printers and MFPs of this type have advantages over inkjet ones: they print faster, operate more quietly, and the toner is a powder that does not dry out. However, photography and a laser printer are not the best pair. Due to the specifics of the toner, the pictures do not have sufficient color saturation, brightness, or detail. In addition, laser printers are simply more expensive and larger than inkjet printers.
  • Sublimation
    . In such printers, solid ink sublimates into gas when heated. Due to this, photographs receive even better detail and quality. The ink itself does not harden or fade. All these indisputable advantages are offset by only two arguments against them – cost (1.5-2 times more expensive than inkjet ones) and narrow specialization.

When printing photo images, the color gamut of the photo is corrected. When correcting, several basic principles are used:

  1. If the main subject of the photo is people, correction is carried out taking into account the most correct skin tone, however, the overall color scheme may change and some colors may not be displayed accurately.
  2. When correcting landscapes, the basis is the correct display of the greenery of plants, or the color of the sky, if the main content of the image is the sky. For winter landscapes, the basis is to obtain the whiteness of the snow.

If you want to color correct your photographs yourself, when ordering you must indicate the option “without correction”, but you must remember that the image you see on your monitor may not match the print due to inconsistency in color reproduction characteristics Your monitor and printing machine. To obtain such a match, it is advisable to order a test print without correction, and then adjust the color rendition and monitor glow to correctly match the colors and balance the brightness of the image.

    Photo formats for printing: overview of main sizes

    The largest standard size is A0, has
    area of ​​one square meter and ratio
    sides 1:√2. The long side of the sheet has
    length equal to approximately 1.189 m, length of short
    sides – this is the inverse value of the indicated
    values, approximately 0.841 m, the product of these
    two lengths gives an area of ​​1 m²;

    Size A1 is obtained by cutting a sheet of A0 along the short side into two equal parts, resulting in the same aspect ratio. This makes it possible to produce one standard paper size from another, which was not possible when using traditional sizes. Preserving the aspect ratio also means that when you scale an image from one format to another, the image’s proportions are maintained.

    Series B

    Photo formats for printing: overview of main sizes

    In addition to the A series of formats, there are also less common B series formats. B series sheets have the same aspect ratio as A series. Only B0 has a width of 1 m. The area of ​​B series sheets is the geometric average of the two subsequent A series sheets. For example, B1 The size is between A0 and A1, with an area of ​​0.71 m². As a result, B0 has dimensions of 1000×1414 mm.

    Series B is almost never used in the office, but has a number of special applications, for example, many posters are published in these formats, B5 is often used for books, and these formats are also used for envelopes and passports.

    Series C

    Photo formats for printing: overview of main sizes

    Series C is used for envelopes only and is defined in ISO 269. The area of ​​Series C sheets is equal to the geometric average of Series A and B sheets of the same number. For example, the area of ​​C4 is the geometric average of the area of ​​sheets A4 and B4, with C4 slightly larger than A4 and B4 slightly larger than C4. The practical meaning of this is that an A4 sheet can be placed in a C4 envelope, and a C4 envelope can be placed in a thick B4 envelope.
    C6 162×114 mm – the main postal envelope format of the Soviet period.

    North American Standard

    Photo formats for printing: overview of main sizes

    Currently used American formats are based on traditionally used dimensions, and are defined by the American National Standards Institute (ANSI). The most commonly used formats in daily activities are “Letter”, “Legal” and “Ledger” / “Tabloid”. The source of the “Letter” format (8.5×11 inches or 216×279 mm) goes back to tradition and is not exactly known.
    North American paper sizes are government standards in the United States and the Philippines (however, Philippine “legal” is 8.5 x 13 inches, which is different from American “legal”), and are also widely used in Canada, Mexico and some South American countries .

    Unlike standard A4 paper, which is a geometric subset of the range of paper sizes based on the International Organization for Standardization (ISO) standard, the origins of Letter paper sizes are lost in tradition and are not clearly documented. The American Wood and Paper Association states that the dimensions date back to the days of hand-made paper, and that the 11-inch page length is a quarter of the “average maximum arm length of a skilled worker.” However, this does not explain the width or aspect ratio.

    To determine the book block format
    it is necessary to decompose the value of the sheet share (/16, /32, etc.) into two largest factors (16 = 4×4, 32 = 4×8), then divide the larger side of the sheet by the larger factor, the smaller side by the smaller factor;

    For example: 84×108/32 => 32=4×8 => [84/4]x[108/8] => 21×13.5

    If we now subtract 1 cm from the larger value, and 0.5 cm from the smaller one, we get the block format after trimming (for publications with landscape imposition, subtract 1 cm from the smaller value, and 0.5 from the larger one).

    Publication format
    is the size of a book block (in length and width) after three-sided trimming.

    The format is determined by the type and type of publication, its volume, circulation, the nature of the illustrative material contained in it, the reader’s purpose, terms of use, etc.
    The term “book format” apparently arose in the era of machine production, when the need arose to unify book sizes for its mass production and commodity exchange.

    The results of measurements of dozens of Russian books of the 11th-13th centuries showed that they did not have stable sizes. The format of the future book was chosen by the copyist based on its purpose, as well as in accordance with the tastes of the customer and his own desires. Altar gospels, richly illustrated and large books (prologues, collections, etc.) were made, as a rule, of large size (the height of the book block is more than 30 cm). These are, for example, the oldest handwritten books: the Ostromir Gospel (1056-1057), Izbornik Svyatoslav (1073), twelve volumes of the “Great Menaion of the Readings” (1547-1563), written on the initiative of Metropolitan Macarius, etc. Books intended for everyday use had relatively small formats and were distinguished by their simple external and internal appearance. An example of this kind of book is the Archangel Gospel (1092) – a cheap book, apparently rewritten by order of the parish church of a peasant churchyard (small four format).

    With the beginning of the use of paper for making books
    their formats were based on the size (share) of a paper sheet. However, there were still no firmly established paper sizes, since they depended on the mesh dimensions of the paper sheet, which were set arbitrarily by the paper manufacturer. Over time, papermakers settled on two main sizes: the smaller one – 30×50 cm; the larger one is 50×70, which, however, was not strictly observed.

    To indicate the format of Russian handwritten books, a conventional unit of measurement was used – dest (Persian dest – right hand).

Technical requirements for digital printing

To print photos without losing quality, you need to follow simple and simple rules for preparing a file for printing.

   When independently preparing a file for printing in a photo center, you need to take into account the format, size and resolution of the image. All manufacturers produce photo paper in certain, standard formats (from A6 to A0) and if the size does not fit into the paper format, then the details of the photo will be lost during printing (we will describe this below).

   In most cases, you print photographs in standard formats (10×15, 13×18, 15×21, 21×30, etc.). Each format corresponds to certain linear dimensions. The sizes of printed photographs in darkrooms and printers are slightly different. Below is a table of standard formats attached to a specific size and pixel size for printing on printers:

Photo format * Linear size (cm) **

File sizes in pixels ***

(for 300 dpi)

9×13 8.9×12.7 1051×1500
10×15 10.2×15.2 1205×1795
13×18 12.7×17.8 1500×2102
15×21 14.9×21 1760×2480
21×30 (A4) 21×29.7 2480×3508
30×42 (A3) 29.7×42 3508×4960
33×48 (A3) 33×48 3898×5669

* Photo format
– linear file size rounded and converted to centimeters.

Linear size of photo
– width and height of the image in centimeters and millimeters. This parameter can be found out simply by measuring the printed photograph with a ruler.

Size in pixels
* – width and height in pixels of the digital image.

    *Pixels are the points that make up a digital image. The more points, the more details we can see.

    Image resolution (dpi)
– a number that relates the size in pixels and the linear size of the image. This photograph parameter is measured in dots (pixels) per inch (inch = 25.4 mm) – dpi (

dots per inch)
. The minimum resolution that is acceptable for printing photographs of acceptable quality is 150 dpi.

  The recommended resolution for high-quality photographs is 300 dpi.

Important to know!

    When printing a low resolution image in a large format, a blurred or pixelated effect will be noticeable. Such prints will not be of high quality. When you print photos from a mobile phone, the images may be of lower quality than when you print from a digital camera. Artificially enlarging or zooming in on an image can also lead to a loss in photo quality.

   Now let’s look at the discrepancy between the file size and the photo format. If you print a photo with the file automatically (in the printer program) adjusted to a standard format, the details of the photo along the edges will be lost, or white margins will be left on the image on two edges.

Series b format

B-format paper sizes are larger than A-series sheets. Such media are used much less often, and in general, few people know that such a format exists.

C size sheets are used to create envelopes for A4 paper.

So, you know all the varieties of European series that the international standard ISO 216 includes.

North American Standard Formats

The North American standard is common in the following countries: USA, Canada, Mexico, Philippines, as well as in several countries of South America. Sheet formats are determined by the American National Standards Institute (ANSI). The paper formats that the North American standard includes differ significantly from European sheets.

Popular title ANSI classification in mm in inches Aspect Ratio Similar ISO format
Letter ANSI A 216 × 279 8.5 × 11 1: 1.2941 A4 (210 × 297)
Legal 216 × 356 8.5 × 14 1: 1.6471
Ledger or Tabloid ANSI B 432 × 279 17 × 11 1: 1.5455 A3 (297 × 420)
ANSI C 432 × 559 17 × 22 1: 1.2941 A2 (420 × 594)
ANSI D 559 × 864 22 × 34 1: 1.5455 A1 (594 × 841)
ANSI E 864 × 1118 34×44 1: 1.2941 A0 (841 × 1189)

ANSI size A, also called “Letter” (21.6 by 27.9 cm), is used in North American countries as size A4. The A3 format almost completely corresponds to the ANSI B or “Ledger”, “Tabloid” format.
