Low chemistry Negative violet CTP plate, for newspaper printing
Advantages:
1. long run-length, suitable for super long ans super fast printing
2. low chemitry, save your cost of chemsitry and water treatment, more environment-friendly
3. simplify the prepress procedures: only 3 steps, preheat, imaging, and drying
4. avoid the possible aging issue caused by strong chemical, to make more stable performance.

Environment-friendly—— Help enterprises to develop
This Low-chemical Violet CTP Plate is a specialized plate for violet CTP
plate-setter and represents the trends of violet CTP technology.It can be applied with low-PH
finisher during the washing-out treatment, which streamlines the post-treatment process and
reduces chemical consumption. No effluent is emitted during the process and less waste is
generated, which meets the requirements of modern environmental printing and improves
enterprise's competitiveness.
Stable developing performance, compatible with various kinds of developers
This Low-chemical Violet CTP Plate is developed by the low PH finisher that go
with it. In the process, there is no need to monitor the change of PH value. This minimizes the
fluctuations of plate performance caused by exhausted chemicals and therefore ensures
more stable printing quality.Besides, the plate is well compatible with other mainstream violet
plate developers.
Reduce equipment investment and maintenance cost
Low- chemical Violet CTP Plate produces high-quality image and its run
length can be up to 200.000 impressions.The plate can be exposed by any existing violet
plate-setters and developed by both conventional and low-chemical violet processors.In the
latter processors, the pre-wash and post-rinse steps together with gumming unit are removed,
making the system smaller and easier to maintai
