Markings and pressure marks on the final print product are indeed a well-known and widespread phenomenon. The causes are pressure, friction due to mechanical processes during production, speed changes, direction changes, paper transfers or (improper) transport. Printing ink and paper selection also play a crucial role. But how can markings be avoided?
Four factors are responsible for these unfortunate side effects in the saddle stitching process:
- the printing press, the printing ink and the paper,
- the transport,
- the finishing machinery (saddle stitchers with three-knife trimmers),
- the human factor.
In the enclosed Whitepaper
, which you can download exclusively from the Muller Martini website, we give you a few golden tips for all four components – with a focus on your saddle stitcher line – on how you can prevent markings.
