 Thermal sensitive CTP plate

There are more types of thermal sensitive CTP plate, but there are two main types of mature, that is, hot melt

Solution type and thermal crosslinking type.

Thermal fusion TYPE CTP plate material is mainly made up of aluminum plate without coarsening, ink-friendly layer and PVA layer (conventional offset printing)

Chemical-free Ctp Plate Or silica gel (anhydrous offset printing with) three parts. Its imaging principle is the use of semiconductor laser diode exposure.

Version of the base of the thermal sensitive coating (that is, ink-loving layer) ink-loving, and insoluble in alkaline potions. After exposure, the coating absorbs energy

New Technology Ctp Plate Amount, solubility increased, can be dissolved in alkaline potions. During development, the exposed part is dissolved in the thief potion

Solution to form the blank part of a printing plate. The non-exposure part is insoluble and forms the graphic part of a printing plate. After developing a

It also needs to be cleaned and glued before it can be printed.

Thermal crosslinked CTP plate mainly consists of coarse aluminum plate and single-layer PS photosensitive layer. The imaging mechanism is

Digital Aluminum Ctp Plates By infrared exposure. During exposure, photothermal conversion materials convert the light energy of an infrared laser into heat energy, making it sensitive

Some polymers in the layer undergo thermal crosslinking reaction to form latent image. Reheat to combine the molecules in the graphic part

Processless Thermal Ctp Plate A cross - linking reaction occurs to prevent the graphic part from being dissolved in alkaline developer. It's important to note that,

During preheating, the blank part also partially reacts, so the image of the blank part should be removed during development. Such as

Fruit temperature is too high, on the printing plate will form a hot mist; If the temperature is too low, it will dilute or weaken the text
