Submitting printing materials to the printing house

  • We expect the submitted materials to be final and complete. Otherwise the Client should coordinate with the printing house to schedule when the final version will be provided. Delays by the Client in submitting the final materials or approving the softproof for printing will extend the agreed upon deadline.
  • The die-cut print files must include the die line superimposed on the design. (Die line colours are: red = cutting; green = creasing; yellow = perforation.)
  • For multi-page documents, all the pages have to be in the correct order within a single PDF, including blank pages. The print file has to be single-page and not a double-page spread because the sheet imposition is finalised at the printing house.
  • For brochures, calendars and other printed materials that can be interpreted in many ways, we recommend submitting a paper mockup or a layout plan.
  • Please note that designs made in Word, Excel, Canvas etc. are usually not printable.
  • By prior agreement, we accept design files: Adobe Indesign (.indd), Adobe Photoshop (.psd), Adobe Illustrator (.ai), CorelDRAW (.cdr), but we always prefer final PDF files. There will be an extra fee for making a printable PDF from raw design files by the printing house if it also includes other corrections.
  • If a separate logo file is requested from the Client by the printing house, the printable logo must be in vector graphics (.pdf /.ai /.eps /.svg).

Automatic colour conversion in the printing house

If the design file contains RGB, SPOT or LAB colours, then the printing house can automatically convert these into CMYK colour space. But this may significantly alter the final look because some RGB or SPOT colours are impossible to produce with CMYK color values and automatic colour conversion just provides the closest possible result. Therefore, it is better if the Designer does the color conversion themselves.

Digitally printed demo samples, mock-ups, prototypes

Digitally printed samples are only suitable for initial impressions and will not accurately reflect the final appearance of the product. Such demo samples are produced using alternative machines and techniques (not coordinated with the printing standard), therefore the printing house does not guarantee that the prototype and the final printed product will be identical in terms of tonality and post-processing elements.

Technical requirements for print-ready files (for the Designer)

  • Print-ready files are composite PDFs which meet the requirements of the PDF/X-1a:2001 printing standard. Only CMYK or SPOT colors are suitable.
  • Recommended colour profile for coated paper is FOGRA39 or ISO Coated v2 300%. For uncoated paper FOGRA29.
  • All print files have to be designed at a 1:1 scale.
  • Minimum 3mm bleed which means design elements have to extend over the edge/trim box. (For packaging, all cutting lines are considered to be the edge.) Texts and other such elements should be at least 2mm away from technical lines.
  • The trim box/layout of the design has to be positioned in the centre of the PDF page. (Trim box also includes the die lines meaning the entire surface layout of the box.)
  • All fonts must be included/embedded in the PDF. This is done automatically if the PDF/X-1a:2001 print standard is selected when exporting to PDF.
  • Recommended photo resolution is 250-300 dpi/ppi. (If an initially low-resolution photo has been digitally upsampled, the pre-press preflight control will not detect this. This upsampling technique does not improve the actual print quality of the photo, therefore the printing house is not responsible for the result.)
  • Total Ink Coverage, Total Ink Limit for carton material is max 300%. (If the total ink limit of the print file exceeds the total ink limit of the printing paper, the printing house reduces it to an acceptable level.)
  • All postpress finishing elements (foiling, die cut lines, embossing, UV-varnish etc.) should be on a separate layer or as a spot colour.
  • To improve readability black text and barcodes should be designed in black only 100K (not rich black).
  • Overprinted objects are printed on top of the objects below them. Therefore make sure to never have overprint on white objects, otherwise the white object will not be visible on the print. Solid black objects (100% K) will always be automatically overprinted during prepress. If you need to achieve no overprinting on black design elements they must be set to 1C/1M/1Y/100K or use rich black 40C/30M/0Y/100K.
  • It is not necessary to add registration marks, colour bars, etc. to the print file. Only crop marks can be added.
