  • Our Printing House does not assume any responsibility whatsoever for any differences in colour combinations following the conversion of colour space others than CMYK or additional colours (e.g.. PANTONE, HKS, etc.). When sending files in colours other than the colours required in the specification, the Client agrees to making conversions and assumes responsibility for all colour differences following this action.
  • In case of more complicated orders, it is recommended to attach printouts of the materials.
  • Our Printing House is not obliged to check the delivered files and it only verifies the general correctness of delivered files. We do not check files in detail and we do not guarantee that all errors and non-conformities have been discovered.
  • File contents are not verified.
  • Our Printing House takes no responsibility for the content or possible errors in a publication.



  • Sheet-fed printing, sheet maximum size: B+;
  • Four-colour work is meant as printing with CMYK inks;
  • Use of additional colours (Pantone) should be clearly stated already at an inquiry stage and repeated in an order. Costs of printing with Pantone are higher than with CMYK.
  • Pantone colours should be indicated according to the Pantone template.
  • Prints from earlier editions do not represent proofs and may be only used as references for a print operator. It is possible that different colour combinations are obtained each time because the method of material preparation, printing process and arrangement of a given piece on a sheet are different. Moreover, paper colour and printing inks change with time.
  • Maximum ink coverage should not exceed:
    • 320% for printing on coated papers
    • 270% for printing on not coated papers

3D varnishing
