Positive ctcp plate is proper for precise color printing. It's a sort of light-decomposition plate.

The photosensitive layer decomposes when exposed too light and it is removed during developing.

So the non-image area is formed and the unexposed region turns out to be printing image area.

Generally speaking, during UV-CTP plate-making, we need to remove a larger area which takes longer time to expose and plate-making is slower than the negative plate comparatively.

 

The positive plate suitable for business printing has a good dot reproduction and processing adaptation.
