In the case of a multi-page publication, stitched or glued, the said element must not be closer than 4 mm. For spiral book binding, essential elements must be 10mm from the outer edge of a page (i.e. 3mm from the spiral hole).
  4. Inner flaps of products folded to the inside must be shorter by at least 2 mm.
  5. All elements in a file (graphics, bitmaps, texts) must be in CMYK colour space.
  6. Percentage paint coverage of surface in any one point may not exceed the value of 350%
  7. Please send PDF as non-separated file – composite.
  8. Bitmaps within a file must have resolution in excess of 280dpi. Line and text graphics as bitmap – above 800dpi.

  12. White texts (select) must not be smaller than 4p
  13. All black objects in the job (100% K) are printed over the background below (no selection possible), even if the file shows otherwise. Beneath all other objects (not 100% K) the background is selected, even if the file shows otherwise.
    IMPORTANT!!! To ensure different settings, please make a clear reference in the e-mail ordering the printing job

  10. Cover and inner parts should have format parsers printed on them in accordance with net size of a publication and the cover should have, in addition, printed markers for bendings.
  11. For brochures of thickness of less than 5 mm it is necessary to retain the technological condition of proportion of cover grammage to inner parts according to the principle:
    inner parts 80g/m² – cover max 200g/m²
    inner parts 115g/m² – cover max 250g/m²
    inner parts 135g/m² – cover max 300g/m²
  12. Packed stacks must be divided with separators and aligned in one direction.
  13. Stacks and covers must be packed in packages with quantity stated (uniform at best).
