Identify the Cause — Minimize the Cost - Part 2 of 3 In Part 1 of this series, the primary focus was on correctly defining and identifying the print defect and how gear-marks can be present regardless of whether your press is gear or servo driven. Part 2 focuses on the operator's reaction to these … Read More...
Identify the Cause — Minimize the Cost - Part 1 of 3 This particular topic is one of the most common problems that continue to plague the flexographer on an on-going basis. It was even hard for me to come up with a simple title because the distinction between bounce, gear-marks and banding is often … Read More...
Ghosting Over the years, APR has shared many articles that assist in identifying and reaction to print defects such as dirty print, ink spitting, and ghosting. But as technology, equipment, and operating techniques develop, we find it necessary to revisit these areas of concern that continue to challenge many of us on a daily basis. … Read More...
Introduction This multi-part article will explore some of the more common but less controlled causes for replacing the photopolymer printing plate. Reasons for replacing an expensive photopolymer plates can vary greatly. In Part 1 of this series we focused on many advantages of deep plate cleaning with automatic plate washing systems, including how we extend … Read More...
Introduction There is certainly no shortage of articles written on how to store and handle photopolymer printing plates in order to maximize performance and extend life. We know that exposure to ultraviolet light and ozone damages the plate once it reaches production, but when it comes down to reasons for replacing an expensive photopolymer plate … Read More...
Overview Many of today's award winning photopolymer platemakers and printers continue to embrace solvent washout technology for both conventional and digital photopolymer plates. Primary reasons include superior print results and print consistency resulting from gauge uniformity, equalized plate surface energy, more repeatable dot generation, and the ability to select from more photopolymer plate materials. Several … Read More...
(Part 4 of a 5 part series) Maintaining the perfect dot is not easy, and to do so we must control several factors, one of which is knowing when the photopolymer plate has become worn to the point that it will have adverse effects on the printed product. But how open have you replaced costly … Read More...
(Part 3 of a 5 part series) Maintaining the perfect dot is not easy, and to do so we must control several factors, one of which is standard dot size. More specifically holding dots within a tonal patch to have the same diameter measurement, or at the very least, a similar measurement.In theory we would … Read More...
(Part 2 of a 5 part series) Maintaining the perfect dot is not easy, and to do so we must control several factors, one of which is slur. Slur is the elongation of a dot and can happen in both machine direction and across the web. However, slur is more common in the machine direction. … Read More...
