The title of this article is meant to address a common mistake platemakers make when performing both a main exposure and back exposure step test. We see this happen more frequently on main exposure tests because the lamp cycle is much longer than a back exposure step test. With conventional bank light exposure systems, we … Read More...

Identifying the Problem If you have spent any amount of time manufacturing or using photopolymer plates, you most likely have run into an issue with plate cracking at one point or another. It is often the assumption that plate cracking stems from exposure to UV light by not being properly stored or protected through the … Read More...
Our Technical Solutions Group (TSG) is often contacted by photopolymer platemakers reporting an inconsistent floor. Typically, they measure the lamp output with a UV-A meter and see that the exposure bed is fairly consistent. They don't understand why early in the day things seem to be fine, but as several exposure cycles are performed, the … Read More...
