PRP Flexo awarded flexo plate patent
After four years of development, PRP Flexo has been awarded a US patent for its new ExSpect flexographic plate development process, designed to provide greater print clarity on both corrugated, pre-printed linerboard and flexible packaging.
PRP (Precision Rubber Products) is a plate processing business based in Indianapolis.
The process enables corrugated converters to direct print onto corrugate and get comparable results as if they were running pre-print, according to a company statement. The same process also enables flexible packaging printers to have a greatly reduced set-up time, as the dot gain received from the new plates is far less than both digital or conventional flexographic plates.
“We had been evaluating and testing different processes over the years, with the goal of reducing setup time and improving print quality for our customers,” says Plant Manager Chris Green. “As the ExSpect printing plates have less dot gain, then the variables that a press operator would have to adjust for are fewer, and the final approval process is achieved much more quickly.”
Testing will be performed by the Graphic Communications Department at Clemson University, says Green, adding that results will be published in the spring.
