Super quality offset plates CTcP, pre-sensitized positive offset aluminium printing  

ctcp offset positive printing plate is a kind of special high-level high-sensitive plate developed, to meet the demands of UV-CTP (CTcP)’s development. It fits both UV-CTP (CTcP) platemaking and conventional CTF platemaking. Its unique formulation and technology ensure that it features high sensitivity, strong compatibility and stable quality. So it is not only suitable for the superb color business printing, but also qualified for the requirement of high speed/ efficiency for newspaper printing.

ctcp offset positive printing plate Features

a) High-quality aluminum substrate

Guarantee the flatness of plates, precise plate sizes and various physical mechanical properties.

b) Complex grain structure & dense oxidize layer

Multilayered complex grain structure and dense oxidized layers are formed on the surface of the substrates through graining treatment with a series of chemical and electric-chemical methods to ensure that plate possesses precise dot reproduction and excellent anti-abrasion.

c) The substrate of hydrophilic treatment

Guarantee the adherence of the photosensitive layer to the substrate; the ink/water balance improved and also overcome the normal contaminations at shut-down time or during printing.

d) Perfect coating formulation

Even cosmetic coatings, extremely high sensitivity, fine dot reproduction, wide processing latitude, runlength up to 100,000 impressions. The extremely high sensitivity and the wonderful dot reproduction ensure that it fits UV-CTP (CTcP) plate-making very much. It is the best choice of the superb color business printing and the newspaper printing.

ctcp offset positive printing plate Characteristics:

Excellent spectral property matches with UV platesetters. Platemaking speed reaches 10-15 2-up sheets/ hour with good dot reproduction. It has good developing property with broaden compatibility and higher run length up to 100,000 impressions, so it is proper for precise color printing.

The positive plate is a sort of light-decomposition plate. The photosensitive layer decomposes when exposed to light and it is removed during developing. So the non-image area is formed and 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.
