Plateroom Process Control Video Series We all know that pressroom process control is important, but plateroom process control is equally important and sometimes gets overlooked. Unfortunately, it doesn’t matter how good your pressroom controls are if you are sending out subpar or irregular plates. Nothing in these videos is groundbreaking, just a friendly reminder of … Read More...
Flat-Top Dots Let’s start by stating what is meant by the term flat-top dot. A flat-top dot on a photopolymer plate is one that accepts the transfer of data from an imaging device to the finished plate at a 1:1 ratio. The 1:1 imaging ratio is measured in the file, post-CDI imaging, and ultimately on the … Read More...
Why should I expect plate quality to improve by bringing in platemaking in-house versus what I experience with professionals that focus solely on platemaking and prepress? An incentive to bring platemaking in-house is often cost savings and fear of a press going down if a plate is damaged, missing, or worn out. In short, what … Read More...
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...
More than just dot %... or is it dot area? So often when we are speaking of dot quality and measurement we default to dot %. But is there more we can measure to understand what aspects of the printed dot are affecting dot size, quality, and even longevity? Even if we focus only on … Read More...
The Continued Evolution of Solvent Photopolymer Plate Processing APR prides itself in not just quoting equipment and providing solution based consumables, but making it a point to thoroughly understand a customer’s needs and goals. As water wash plate technologies continue to evolve into a viable competitor to solvent and thermal processing through improved print quality … Read More...
There are essentially 3 methods of processing or washing out photopolymer plates. These processes include solvent wash, thermal removal, and water wash processing. The water wash plates of the past were not known necessary to be the best printing plate but they were known to resist ink swell and last a long time. In the … Read More...
Our industry experience a huge leap forward when direct imaging of photopolymer platemaking was introduced. Elimination of films and chemistry along with the many other benefits CDI has to offer is arguably the most significant advancement in plate quality over the past 3 decades. One not so good thing about this very positive move to … Read More...
Why is this important? If rotational speed does have an effect on outward force, then one could surmise that with increased press speed we will see more force between the photopolymer printing plate and the impression cylinder or drum. The answer to the question is "yes." So why is this important to consider? Well consider … Read More...
