PRE-PRESS

Pre-press is the most important stage before the printing process.
Please check this page to avoid mistakes in the file preparation process,
to choose an appropriate colour profile and to gather some other very useful pre-press information.

To achieve better print quality we use Heidelberg’s computer to plate technology. To check and assemble digital
printed materials we have a Heidelberg Prinect Prepress Workflow software with its versatile possibilities.

Our team is always looking for new ways to improve quality and service. To that purpose we have recalibrated our
printing presses and are renewing our profiles. This is to give your printed matters a sharper image with more
vibrant colours.

What changes in everyday workflow are the profiles. To be in accordance with ISO all our partners need to change
the old profiles to new ones. New profiles are available from the 1st of May 2019 on www.printbest.ee/en/repro

For coated papers the new profile is: “PSOcoated_v3_FOGRA51”
For uncoated papers: “PSOuncoated_v3_FOGRA52”

In case of reprints this can mean a slight change in colour since the curves are changed to make the pictures
better.

If there are any questions regarding this we are happy to help. Please turn to repro@printbest.ee, or personal Key
Account/Sales manager.

Printfile requirements

Technical requirements for print files

  • We accept composite PDF which meet the requirements of the PDF/X:1a (2001 or higher) standard.
  • PDF files must be unseparated (composite). Blank pages have to be included in the content file.
  • If endpapers are ordered as selfends, endpapers should be included in content file.
  • Cover must be in seperate file, on spread pages (also the inside cover).
  • Before making the cover file ask the cover drawing (hardcover book) or spine width (perfect bound book).
  • Size of all pages must be equal according to order – if book is ordered in size of 210×297, then this size must be defined in document properties.
  • All fonts have to be embedded.
  • Bleed size for every document must be applied: contents, soft covers and endpapers – 5mm, hardcovers – 18mm.
  • All backgrounds, lines, images and other design elements that run up to the edges of the format have to be positioned 3-5 mm over the edge of the format, so as to reach into the bleed.
  • To avoid important elements from being cut off or altered in any other way in post-processing, they should be positioned 3mm from the edges of the paper.
  • File should be prepared with crop marks (this can be applied automatically just before exporting file to PDF).
  • Black text and colored images must be in one file.
  • Correct resolution of colour pictures is 300 dpi, for bitmap files 600 dpi.
  • Always should prefer vector objects.
  • If the print file contains colours from the RGB or Lab colour space, then they are automatically converted into CMYK colour space in the printing house, which may significantly alter their hues. This also goes for the automatic conversion of colours from the SPOT colour space into CMYK colour space.PMS color name should be number.
  • The design of the print file must take into account for the following reasons:
  • That all black (K-100%) objects (text, lines, backgrounds) are automatically subject to black overprint.
  • If unoverprinted blacks are needed, the objects must be designed accordingly (C- 1%, M-1%, Y-1%, K-100%).
  • Minimum line weight must be 0,05mm and in one color.
