The double layer CTCP plate is a type of plate material used in computer-to-plate (CTP) technology. It is composed of two layers of different coating materials that together control the absorption of ink to improve printing quality. It has a unique double layer coating structure and a range of significant technical features.
The double layer coated positive CTCP plate has high sensitivity, good developing latitude, excellent resolution, consistency, chemical resistance, and printing effect without the need for baking.
CTP board substrate
The base of the double layer CTCP plate is typically made of 1 series aluminum alloy, including products like 1050 aluminum plate, 1050A aluminum plate, 1060 aluminum plate, 1070 aluminum plate, with the main state being H18 and a thickness range of 0.15-0.4mm to ensure stability and durability of the plate material.
