Features
Eco-Friendly: Utilizes a low pH finisher during washout treatment, reducing chemical consumption and liquid waste.
Stable Developing Performance: Compatible with most brands of violet plate developers and less sensitive to the pH value of the finisher.
Lower Investment and Maintenance Cost: Compatible with simplified processors, eliminating prewash, post-rinse, and gumming steps from conventional processors.
Higher Run Length: Features an outer protective layer that shields the sensitive layer from damage, resulting in more impressions per plate.
