The PS version is a pre-coated photosensitive material. Printing is composed of many links, and every step must be strictly operated to ensure the quality of printing. There are many reasons for the poor printing resistance of the PS plate. The printing conditions of each printing factory are different, such as: running light (before exposure, before development); insufficient density of positive film; overdevelopment; drug attachment; with PS A strong plate cleaner and roller cleaner are used in the version of the cleaning agent; the printing pressure is too large; the paper powder and the like may cause a decrease in the printing durability.
The main countermeasures for treatment are to use yellow safety light to fully shield the harmful light; to reproduce the positive film (density above 1.5); to develop under standard conditions; to arrange the appropriate developer, pay attention to the development time; do not use inappropriate drugs Reduce the number of wiping; use a softer cleaning agent; adjust the printing pressure and so on.
The printing factory can refer to the above reasons to see if you have neglected a certain link. At the same time, you can also participate in Fuji Xingguang's plate-making training to master the correct exposure, development methods and operating procedures to achieve the best use of the plate.
