The Correct Use Of Printing Rollers

In the printing process, in order to achieve uniform ink, bumo, colloids must maintain a certain viscosity. But because of the roller with long, its surface with water loss, adhesion is reduced. In addition, because paper dust, paper and others, that would affect ink transfer, but also prone to uneven ink ills. To keep rollers certain viscosity, should prevent fast ink drying the rubber roll crusts, to add drying oil ink control of drying oil. In General, resin ink and white dry oil amount not exceeding 5%; oil type oil ink and white dry no more than 10%; Red drying oil quantity about 2%, so as not to impact roller with ink printing quality. To keep the rubber roller cleaner, should, as appropriate, clean rollers, inter alia on the colloidal impurities, paper dust to enhance ink performance. In the offset printing operations, printing ink emulsion is a must, but because the "water inks" arising out of ink emulsification, forming hydrophilic base on smooth roller, roller deinking corrosion plastic fountain. Therefore, on the premise of not sticking, less fountain, the better.
