UV ink curing test

[janezl]

Is there a method to find out, how well certain UV ink adheres and cures with certain paper - out of printing press?
My KISS idea for testing:
- hopefully, producer of the UV lamp in the printing press will reveal (at least) the UV part of energy, emitted by lamp. Length of the lamp, multiplied by speed and sheet length, should give me energy (J/m2), received by ink on the printed sheet
- same scenario should be applied to sheet of paper with UV ink, put under the copy frame (normally to copy film onto classic PS plates). This is my only UV emitter available. With variable exposure time, I would try to get same amount of energy on the sheet

With scratch or glueing tape method, I would check adherance and curing of UV ink.

Any better idea?

We at Eltosch offer a UV meter that you can actually measure the amount of UV exposure energy in Joules per centimeters squared(J/m2) on any type of stock and any type of press.
Simply by adhering a test strip to your stock, then taking this strip to our measurement device, you get the actual measured dose of the UV energy in J/cm squared. This is the amount of UV energy times the amount of time exposed under a UV lamps system. You can keep the information save it and even download it to a computer. If anyone would like additional information, Please contact Domenic DiRenzo at Eltosch 508-879-0092 or our web site at eltosch GmbH, UV Technology, Dryer Systems.
