Factors affecting the quality and speed of offset printing is broadly divided into mechanical factors, printing technology factors, material factors, operating environmental factors and power factors.
Printing machinery affect print quality about dye sublimation ink.
A. We require vacuum tank to add water to water bucket in offset printing, sometimes not reach the vacuum requirements, automatic water will often fail, leading to water shortages, operator little attention occurs failure of rub dirty paste version on printed materials.
B. Installation and commission of offset press, high-speed offset press has most demanding for machine base leve. If the machine loses level, roll journal and bushings wear faster, it will cause ghosting, taping and other printing failures.
C. Often print the same specifications of the product will lead to embossing roll surface occur linear depressions, then print large size of some of the product, there will be a blot white bars, affect product quality.
