PS version is not high against the problem

PS version is a kind of pre-coated photosensitive material, printing is composed of many links, each link must be strictly operated in order to ensure the quality of printing. There are many reasons for the poor printing-resistance of the PS plate. The printing conditions vary from printing house to printer, such as running light (before exposure and before development); insufficient density of positive printing films; excessive development; adhesion of chemicals; Strong plate cleaners and roller cleaners are used in plate cleaners; printing pressure is too high; paper powder and more can cause a decrease in the resistance to printing.

The main countermeasures to deal with yellow safe lighting, full coverage of harmful light; re-create positive film (density of 1.5 or more); developed under standard conditions; configure the appropriate developer, pay attention to the development time; do not use inappropriate drugs Reduce the number of wiping; Use cleaner cleaning agents; Adjust printing pressure and so on.

Printers can refer to the above reasons to see if they have overlooked a certain point. At the same time, they can also participate in the Fujitsuguang company to organize plate-making training, to master the correct exposure, development methods and operating procedures, to achieve the best use of the plate material.
