- Uncropped elements must be positioned at least 3 mm away from the edges of the final format
- Line width not below 0,2 pt. Negative lines 0,4 pt minimum

- Set black to overprint, everything else to knockout. We will set trapping and underfilling.
- Elements set as overprinting will be maintained
- Lines, fills and fonts must be set as vectors for a high quality conversion
Colors:
- Use CMYK model, do not use RGB model
- Clearly define spot colors (HKS 8, Pantone 234, for example)
- Set white pre-print 0,2mm smaller along the edges
- Flatten transparencies
- Range of tonal value: For halftone areas and gradations between 5% and 95%. Values outside this range may swerve or blur in the print.
Fonts:
- If fonts are not provided, convert them into paths

Punching and cutting outlines:
– Provide images with punching and cutting outlines as one file for viewing
– For further processing, create an individual file with punching outlines and set the spot color to overprint
