摘要

When assessing the differences between photopolymer and elastomeric printing plates, there are several aspects to consider for each, including materials, speed and cost. But the biggest difference between the two is when creating the image, one requires addition while the other necessitates subtraction. With photopolymer plates, the more common of the two, exposure to UV light cures the image, with the rest being removed via washout or a thermal process, thus building the image onto the plate. When working with elastomeric plates, a laser is implemented to directly engrave the image into the material, removing any surface area that will not be printed. While one process is not necessarily better than another in terms of print quality, package printers will need to be aware of which process best suits their needs. According to Ryan Vest, the global director of innovation for MacDermid Printing Solutions, it is essential to understand the interactions between the plate, ink and substrate, regardless of the technology employed.
