A plastic substrate used for analog and digital offset printing plates.
The polyester substrate is coated with an emulsion of either silver halide, which is imaged with lasers, or a toner-based coating, which is similar to the technology used for laser printers and copiers.
Polyester plates are suitable for smaller print jobs of less than 25,000 impressions.
Improved technology has resulted in plates that produce excellent results, allowing them to be used for almost any type of short run application.
