Processless plates eliminate the need for chemical processing, improve working conditions, reduce costs, and enhance print quality. In addition, these plates benefit the environment by minimizing chemical use and waste. Driven by their efficiency and environmental benefits, the adoption of these plates has rapidly increased, making them more likely to become industry standards. Companies are increasingly embracing these technologies to achieve complete automation and sustainability. Over the past 20 years since the introduction of processless plates, plate manufacturers have continued to develop new technologies, leading to significant improvements in performance that are now comparable to those of process plates. This study introduces the basic performance characteristics of processless plates, including (1) developability on a printing press, (2) printability, (3) visibility, and (4) scratch resistance, while also presenting the latest technologies. We also report a technology for eliminating interleaf paper, which significantly reduces environmental impact.
