Not much to go on here, so I have to ask some questions.

  1. Is the UV coating aqueous or solvent-based?
  2. Is the Heidelberg print delivery system compatible with the UV coating chemistry?
  3. Will the Heidelberg printer give sufficient coat weight of UV coating for your application?
  4. What is the solids content of the UV coating (meaning, will it require post-coat drying)?

The UV coating will be solvent based

We have asked the roller manufacture about the rubber I think we are going to have to change the rollers to EPDM rubber same with water form rollers

We hope to print a full solid the product will be previously printed and dry most applications are covers for perfect bound magazines this is to provide gloss coverage

(We tried varnish and UV is around 50% glossier)

We plan to use LED UV lights (less heat and smaller)

No id of the solid content but the UV fluids are not as thick as ink

Thanks for answering my questions.

The %solids of the UV coating is very important to your application as that will tell you what kind of drying setup you are going to need.

Gotta get back to a trial I'm working on - more later.

Thanks I will find out % solids on Monday
