Is there any color difference in the printing color of the packaging bag? How to do?

For a bag to have bright and bright color, even ink, bright pattern, is a good bag. Printing color difference is also one of the important factors affecting the quality of the packaging bag, in the whole printing process of the packaging bag, the reason for the printing color difference of the packaging bag is various, there are bad factors on the technology, and there are also raw material reasons for. How can we avoid deviation between the finished product and the design manuscript after printing? Below, professional soft packaging manufacturing Soonseal packaging combined with their own production of printing exquisite packaging bag experience to give you a summary of how to prevent the packaging bag color difference problem, take you to see how to print exquisite packaging bag.

1. Printing color difference caused by pressure discomfort
The ideal printing process is on the basis of "3 balance", in order to balance the printing pressure with a thinner ink layer so that the ink can be more uniform. When the printing pressure is insufficient or uneven, the lining body and the printing plate have poor contact, it is necessary to increase the amount of ink to meet the visual effect of the printing plate, but this will not only increase the consumption of ink but also easy to produce printing color difference and sticky quality problems.

2. Printing color difference caused by poor ink roll
Lithography, relief printing process, printing products can obtain uniform ink, cots quality has a vital role. The printing color printing machine is generally equipped with an ink roller, uniform ink roller, and inking roller three, which is more influential on the ink shade rubber roller and inking roller. The elasticity, viscosity, centricity, hardness, and surface finish of the ink roller largely determine the quality of the ink. If the elasticity of the inking roller is poor, the viscosity is insufficient, the roller body is eccentric, the colloid is hard and the colloid finish is poor, the printing process is easy causing the uneven or unstable phenomenon of brush ink so that the printing ink of each sheet inconsistent.

3. Printing color difference caused by poor ink
The process shows that printing ink layer thickness and viscosity are not easy to produce printing color difference. When printing, only the moderate and uniform printing ink layer can better ensure the ink quality of printing products and effectively prevent the occurrence of sticky printing failure. If the printing ink layer is thick, its viscosity will increase accordingly, which is easy to causes the phenomenon of powder dropping and hair pulling on the paper surface in printing, and then affect the uniformity of ink color. But if the printing ink layer is thin and thick ink is too small, the ink color of the printing is light, and the visual effect of the printing is poor.
