Support » Backprint Decoding

Backprint is service information located on the reverse side of a print. The content of the backprint depends on the type of printing machine and printing options used. The backprint is decoded as follows in our laboratories:

Example of Print from File

1. Name of the laboratory.
2. Number of the frame on the film or the file name is indicated in parentheses.
3. Number of the print in the order (internal numbering of the machine).
4. Source of printing, for example:
   CN - colour negative
   CP - colour positive
   HD - file
   BN - black and white negative
   BNO - monochrome film
   SN - if sepia option from negative is enabled in the machine setting
   
5. Number of the order according to machine numbering.
6. Channel number of paper options.
7. Numbers with minus or a plus stand for color channel correction in the sequence of yellow, purple, blue, and density. N means that there is a correction: A means 9, and so on to F, which corresponds to 16.
8. A two-digit number means automatic correction of negative density. Three dashes stand for printing from files. The first number is also replaced by a letter after 9, that is B9 means 119.
9. Other proofs have the following meanings:
   AC - automatic contrast
   ACh - automatic contrast highlight
   ACs - automatic contrast shadow
   SA - saturation
   AS - automatic sharpness
   GR - graininess suppression
   
10. Automatic scaling.
11. Manual scaling.

Backprint of Noritsu QSS 2301 Optical Machine

(This optical machine has been switched off and removed from the base of Fotoproekt due to the reduction in demand for this type of service, information on the backprint is given only as an archive for previously printed photographs)

1. Name of the laboratory.
2. Number of the frame on the film is indicated in angle brackets.
3. The last three-digit number is a frame number in the order (the internal numbering of the machine).
4. The first three-digit number stands for the order number (internal numbering of the machine). This value and the previous one are necessary for the operator to define the order of the photographs, and to distinguish them from one another order in cases where, for instance, several frames are printed from a dozen films of one order.
5. Four numbers (two asterisks may be printed instead of the numbers). The first two numbers stand for the number of paper channel of the machine, the last two mean a film channel (2 asterisks mean mix channel).
6. Four numbers in the order they are printed show the operator's correction YMCD:
   Y - yellow
   M - magenta
   C - blue
   D - density
   The letter N means there has been no manual correction.
7. The last but one number (before the brackets) stands for the internal setting of the machine's printing mode.
8. The last figure (in parentheses) is the zoom size, depending on the printing size, and can be changed when cropping (it does not represent scale as in digital machines; but rather conventional units).

You can determine which machine made the print by looking at the way Б─°FotoproektБ─² is written.
