A, between rubber roller pressure is overweight rubber roller pressure, can increase the friction between the rubber roller, make the rubber roller heating heating, increase extrusion expansion between rubber roller, accelerate the aging and deformation of the rubber roller, to speed up the ink and water emulsion process, this is not conducive to ink.

Solution is: between rubber roller pressure should be basically the same and contact pressure on the layout. Experience is to use a 1500 yarn, 3 cm wide plug inserted between rubber roller, can feel a certain tension.

After scrubbing, with a clean cloth to wipe it again then put rubber roller to the machine, for next time use.

Second, the processing surface of the rubber roller surface crystallization crystallization closed rubber roller surface of wool stoma, deprive rubber roller ink role, cause the ink transfer uniform cloth, prone to ink emulsification.

Solution is: to unload of the machine, rubber roller, with flat shelf, take cloth glued kerosene and pumice, forcibly evenly to clean the surface of the rubber roller, the roller surface crystallization layer erase, show the original plastic roller rubber color, then use the car wash water or gas residue on the rubber roller of kerosene and pumice to clean, install and adjust the good rubber roller pressure again.

Three, on the rubber roller bearing maintenance in the high-speed operation of the machine, rubber roller bearing wear is obvious, especially the operators of pile bearing maintain cloth notice at ordinary times, the wear is more severe. Rubber roller bearing is damaged, it would jump produce rubber roller friction and extrusion, shorten the service life of rubber roller. And will make to the printed products are "ink, water bar" phenomenon. So require operators once a week to take off the rubber roller, called bearing butter, to those who wear badly, turn the bad bearing change, to ensure the normal use of rubber roller.

Four, workshop environment of the influence of rubber roller in hot and humid weather and environmental production from the surrounding of the dust float in the sky, the high-speed operation of the machine to make the rubber roller surface temperature rising, rubber roller in heat expansion, increase the friction of rubber roller, it will shorten the service life of roller.

So in the factory of conditional, offset printing plugin required to install air conditioning, keep workshop clean and tidy, clean, make the machine production operation in the good environment, only in the good environment of workshop production, can produce high quality products.
