The most important factor affecting the promotion of CTcP technology - sensitivity

The UV-setter CTcP platesetter can use any conventional PS plate for exposure plate making. Basysprint used the world's more than 60 kinds, including our dozens of traditional PS plates, to make plate experiments.

However, the sensitivity of the PS version is different, and the plate making speed is also different. For example, the high-sensitivity negative PS version N81 of Agfa can produce about 10 wafers of 1030mm x 800mm per hour. This is so far, the world On the commercial negative PS version plate plate making a fastest product. The negative-response PS version with medium sensitivity, such as YN-II in the second Film Factory of Lekai Group, can produce 10-30mm x 800mm counter-parts, 13 to 15 sheets per hour, and the sensitivity is similar to that of YN-II. In the PS version, only 11 to 13 templates of the above size can be produced per hour. The general sensitivity of the domestic (150-200mJ/cm2 naphthoquinonediazide positive PS version, can only be made out of the above size 5-8 sheets per hour, it can be seen that the sensitivity of the PS version is different for the plate speed great influence.

Among various CTP plate making technologies, the silver salt plate has the highest sensitivity, being 105 to 107 times that of the thermal plate and the ordinary PS plate. It also has the fastest plate making speed. Hundreds of release plates can be produced per hour. The control link is not the exposure speed, but the post-processing links such as development. Sensitivity of high-sensitivity photopolymerization CTP plates ranked second, and plate making speed was approximately 100 sheets per hour. The sensitivity of the thermal CTP plate and the traditional PS plate are at the same level, and only 15 to 25 templates can be produced per hour on the thermal platemaking machine and the CTcP plate making machine. The slow speed of plate making is considered to be the main drawback of these two plate making technologies. Especially in the field of newspaper industry plate making, the timeliness is highly emphasized. Therefore, the faster the plate making speed, the better, and the better the timeliness of commercial printing. Sensitivity of thermal CTP plates and traditional PS plates has become a major factor in the promotion of thermal CTP technology and CTcP technology.
