How to cut off color, packet control the color difference, we have a good way!

Tuned color ink, the printing and use, often with the standard color difference, this is a tough question to completely avoid, only is to reduce the color difference to the lowest limit, what is causing this problem? And how to control? And how to improve the accuracy of color ink? Today, the professional manufacturer of flexible packaging packaging on these issues to specific solutions for you. 1. Printing method most imported from the British small printing ink factory, the machine mesh is on the flat version, through round embossing roller with a move to complete printing, printing membrane printing machine is circle pressure circle method and mesh is on the circumference of roller of the rolling. Both the number of the mesh line, the viewpoint is quite different, which makes the same ink, under two kinds of printing method there is a big difference, sometimes just a matter of color dark light, but hue, transparency can bring larger different functions. Some small factory use scraping rod sample, is even worse. With plate making factory proof press to color, effect is much better than import small printer, and the price is about the same, this kind of machines can be made into the same version of printing, and according to different levels need to plan, the depth of the printing pictures, this makes the roots and printing plant in the same printing method, together with the plate, also with the same printing. 2. Version different calendar has a different version of the deep, deep deep understanding of the factory for the calendar ink also affects the accuracy of the color. Obviously, assume that ink factory of color in 45 & mu; M deep printing, and customer's version is far less than 45 & mu; M, printed color becomes shallow, on the other hand, will be darker. Some people think that according to the supply of users is the specification of the ink control to the ink, deep can need not consider, in fact this is the concept of a theory, is not the case in practice. From theory, said exactly the same two ink ( For example, the glass of ink dividends two) , either version of the deep and shallow ( Other conditions are the same) The hue is together. But in the practice of toning, impossible distribution of exactly the same ink, so often there is such a phenomenon; Sometimes is the light version is closer to ( Can be arrived at customer's requirement) Deep version, but assumes that seal, color is much worse, so it is very important to grasp, for version deep customer's version of how deep, how deep it is bound to use the version for printing of color. 3. Viscosity ink factory palette of color printing viscosity as far as possible with the offset presses this ink printing viscosity, the farther the poor, will also result in color difference is bigger. Color ink factory with 22 s, and customers with 35 s, during this time many color must be deep, shallow many vice. Some ink factory doesn't attach importance to this problem, not to consider the use of printing viscosity, all together with the viscosity of the sample according to customer's specification ( Ink sample, sample calendar) , constitute a large color difference. 4. Printing materials, printing ink factory of color in different materials and printing plant ( Including other processes) Will constitute a large color difference. Some ink to print a layer of white ink color will up closer to with customers, some are the opposite. Some compound after the change is not big, some changes are very big, for example, some transparent color, ink color so when, must understand the customer's process, the root end including: whether the palm print white ink, composite materials, whether oil polish. In theory, and printing ink factory when color printing conditions by the ink printing conditions when the closer, bring up the ink, the higher the accuracy. But, because the bondage of conditions, the difference is still has many different, for example: printing speed, watch color environment, printing roller pressure is impossible together, only need to control well the four part, must be able to trek ink factory color accuracy greatly, and poor printing excellent small exquisite packaging.
