Rubber roller and other things before use should be strictly check the application environment is consistent with the operating conditions, through practice and observation for a long time that it specific maintenance in application and maintenance methods are as follows:

1, before printing
There is no body check between the roller and the roller, rubber roller is intact, roller pressure is uniform, to confirm the normal cleaning, clean can be used only for printing.

2, printing
Rubber roller should always keep a good contact state in operation, the stress is uniform. Whether the print format width, will make the ink roller rubber surface oil lubrication; as many cots accumulated amount of ink, should adjust the amount of ink, to ensure that the printing quality. In ensuring the premise of printing speed, to prevent the ink drying too fast, cots viscosity, surface crust phenomenon, the need to join the dryness of the oil ink should control the dryness of the oil consumption, to prevent the resulting in the operation of the rubber roller not ink and ink unevenness.

3, after printing
To timely roll and roll and roll and a printing plate disengagement, removable load pressure, prevent glue surface deformation caused by static pressure. To clean the surface residual cots ink, prevent dry ink, ink ink film, shit and dirt floating in the rubber surface, (especially the two end nylon roller ink block) and operation will damage rubber roller surface roughness, serious will produce pitted dregs phenomenon.

4, rubber roller cleaning
Cots must make special cleaning agent will cots clean before printing, to keep the rollers, the surface is smooth, the stand-by.
Not timely cleaning, ink through the roller surface villous microporous adhesion in the pores of dirt, paper wool, will be attached to the roller surface. If the parking time is too long, ink conjunctival causes two roller contact surface adhesion, and driving while tearing rubber surface, so that the rubber scrap. Cleaning is not in place, will produce the phenomenon of lead glaze, dear ink, ink is reduced, or even cause the deinking. Glaze the cots surface hardness, elasticity, and accelerate the roll wear, leading to the adhesive surface pits, cracks, caused by residue phenomenon, affecting the quality of printing.

Note: glaze refers to cots surface hardening is the mirror like appearance.

5, the cleaning requirements
①The non flammable, safe and reliable, no pollution to the environment.
②The washing ability is good for printing ink.
③ No corrosion on cots, no deformation of the rubber surface.
④The UV ink rollers are used "UV ink" special cleaning agent.
⑤The lees fountain roller using "alcohol dampening roller" special cleaning agent.

6, cleaning method
The boot operation, to the inking roller spray cleaning agent mode.
