CTP Plate: The Difference Between Traditional Printing Plate And Modern Printing Plate
Nov 12, 2018

The primary difference between printing types is the sensitivity of printing plates. The sensitivity of various plates in the CTP version is roughly as follows: traditional printing version 2000mJ/cm2, thermal printing version 150mJ/cm2, polymer printing version 0.04 mJ/cm2, and silver salt printing version 0.03 mJ/cm2. This difference in sensitivity is not only for exposure, but also for all production processes. The need to make photosensitive emulsions and coated aluminum plates is very detailed to Fuji Starlight. It is necessary to strictly control and insist on small promised errors.

A director of printing skills described the production of traditional and digital printing plates. He said: The pioneers of CTP skills put the film in the template, and then copied it on the printing plate, exposing it with thousands of watts of UV lights for a few minutes. Digital printing. It is then developed, washed and coated. For this reason, within a few decades, a wide range of processing options will be used, so that each printer can use a better or worse template box to achieve a stable printing effect.

Polymer printing, digital silver salt printing and photopolymer printing are quoted about twice as much as the traditional printing plate quoted Gaochu. If the printing plate is developed and the higher cost of entering the market is used to explain this scene packaging logistics, customers can accept it. Because the process from the craft version to the digital version has been completed with CTP, the production process has been greatly simplified. The thermal sensitivity skills presented in 1997 began to be used on CTP. In 2000, Akfa introduced a purple laser printing plate that can be processed under yellow safety light. Since the introduction of photopolymer printing plates, it has developed a selection that has become extremely attractive.

Hot printing plate, this version of the original money Gaoyouxuduo factor. The mechanical transmission of the digital printing plate starts from the plate box to the exposure machine, and then from the exposure machine to the development and post-processing system UV printing. The request for the printing plate is higher as long as the use of advanced aluminum is satisfactory. In addition, it also has a higher request for intermediate barrier paper because it is necessary to actively remove the barrier paper on the exposure machine. For example, for the newly introduced: Energy Series Printing, raw aluminum used for the Energy Marathon Printing Edition is required to be rough during special operations. For the sake of progress: The chemical resistance of the Energy Elite printing plate, the printing plate is coated twice with Lekai II glue, which means that the customer's demand is an additional investment in the second coating unit.
