Paper cups printing color difference matters needing attention

by:New Debao Machinery     2020-08-18
Often there will be a customer said to us, paper cup have off color after printing out. Outside the industry, the color difference of two, one, called normal chromatic aberration, chromatic aberration called category. Factors that can affect the color difference when paper cups printing a number of reasons: one, now we use computer monitors are liquid crystal displays, but if you to the advertising company, the company have a look at will know that, they are all flat screen monitor, why, why is the color liquid crystal display and printing color difference is very big, there are a lot of color, the color of the display cover and printed color is almost completely different. Second, the paper cup with the paper is pitted, like offset paper, copperplate printing is light, on the copper plate printing, coating, used to reflective, so there are two kinds of color printing, one is C, one kind is U face, surface is smooth, C U face is pitted, the color of the printed on paper cups, because is pitted, and become a little bit dark, no light on the coated paper. So everyone at design time, the best design is bright, it will have better feeling. Three or four color overlay less as far as possible, if CMYK four-color overlay, come out of the stack, mostly black, color, registered with the CMYK39393939, superposition of two primary colors as far as possible, if must be four color overlay, a higher requirement to the color, proofing, please. Hope the broad masses of consumers aware of the computer to see the effect of absolute is not equal to the real printing effect.
