Plate Demounting Made Easy

Plate Demounting Made Easy

How ink residues can affect plate demounting behavior and what you can do about it.



Plate Cleaning - Which Method is Better?

When it comes to plate cleaning, the industry likes to rely on the support of machines. Many flexible packing printers use plate washing machines to clean printing plates. Sure, it’s more comfortable and saves time, but is it really more effective?

One of the biggest drawbacks of using an automatic plate cleaning machine are the nitrocellulose (NC) solvent-based ink residues that are left on the reverse side of the plates. During the cleaning process the printing plates become contaminated with the NC ink and cleaning solvent mixture. Even the thinnest layer of ink can potentially cause serious damage. Internal laboratory tests show that the thickness of the ink layer is a critical factor: the thinner the layer, the harder the demounting behavior of the plate. For this reason most machine operators don´t notice the ink residues on the reverse side of the plate, they just feel the increase demounting force required to remove the printing plate. To avoid these negative side effects, we recommend an additional cleaning step after the automatic plate cleaning. However, this additional effort is not an efficient or feasible solution for most companies. A more practical solution is to use a tape with ink resistant plate side adhesive to help prevent the risk of plate damage during the demounting process.
