【 Packing 】 What are the main source of printing color error? 1. By each printing unit mechanical synchronous error and version roller precision machinery itself reason caused by error of this type of error is intrinsic to the mechanical, this kind of error only through improve the performance of printing machinery and version roller precision of the method to solve them. 2. When plastic film in the printing process is tensile, compression, friction, shear force, and a variety of external force in various ways, due to a variety of combination force and make the membrane produces a variety of mechanical effects, therefore, reduce the influence of the strength of plastic film and make the basic equal to this effect in each printing unit, to improve the printing accuracy has important significance. 3. The third type of error is caused by the following factors: the film intrinsic properties such as modulus of elasticity wave; Dry hot air temperature in the oven, air volume, wind speed difference, and the change of the ink viscosity, producing the change of environmental temperature and humidity, printing its thickness and the change of elastic, this kind of error continuously changes over time and deviation value does not necessarily is a kind of time-varying system error.
