Negative PS plates produce an image when exposed to light, with the exposed areas remaining soluble and the unexposed areas becoming insoluble. They are ideal for printing large areas of solid color. Offset printing is a common method for producing high-quality prints, and PS plates are an important component of the process.

Because all of our plants are ISO 9000 certified, we produce high performing and easy-to-use PS plates to increase your printing productivity. You can expect consistency from product to product, box to box, batch to batch.
