Experience in Using Thermal CTP Plates

At present, there are not many varieties of thermal plates sold on the domestic market, and most of them are non-preheated. The reason for this is considered by customers to be the guiding issue of CTP equipment suppliers. Because non-preheated plates are used, one preheating furnace can be reduced in equipment supply, so that the quotation for the entire CTP system will drop a lot. As a result, non-preheated plates will appear as soon as the CTP is available on the market. Suppliers are beginning to recommend non-preheated plate equipment. Regarding the difference between preheated and non-preheated plates, the difference between the two is not significant from the perspective of the use of the customer company.

However, in the imaging of high-precision dots, pre-heated plates exhibit advantages in the representation of fine and fine dot shapes. Therefore, when printing conventional AM sites below 200 lines, both performed very well. When printing with high-precision FM dots, the advantages of pre-heated plates are highlighted. The preheated plate will make your prints delicate in the high-grade tone. The high-end expressiveness embodied in the pre-heated plate DITP GOLD used by the customer at Kodak Polyurethane Group is very good. . This makes 10um FM network printing possible. Of course, this is only limited to this customer's pursuit of high-end printing quality. If an ordinary high-precision amplitude modulation net is printed, using the ELECRA EXCEL from Kodak PolyGraphics will be sufficient.

In addition, customers have used some of the plates of other brands. In practice, they found that the cooperation between the plate and the press is also a crucial point. They once kept the plate speed, the potion temperature, and the potion concentration of the plate processor unchanged, but only changed the speed of the brush wheel, which would affect the shape of the plate and the dot shape. Therefore, the customer finally selected DITP GOLD as a printing plate.
