Customers often report color difference in cup printing. What is the reason? Let's have a look.

What causes the color difference of paper cup

There are two kinds of color difference, one is called normal color difference, the other is called category color difference. We all find that the colors displayed on the LCD computer are different from each other. Therefore, many customers think that the color they see should be printed like this. In fact, it is determined by completely different colors.

The computer is all LCD, but if you go to the advertising company, the film company will know that they are all flat. Why, the reason is that the LCD display is quite different from the printing, there are many colors, and the display is almost completely different from the printed one, because the LCD is in RGB mode.

Try to minimize the four-color overlay. If CMYK four-color overlay is used, most of the overlapped ones are black. Just like the registered color and cmyk39393939, try to overlay two primary colors. If you have to overlap four colors and have higher requirements on color, please proofing. Color proofing is a method of printing milk tea cup by the way.

The paper used for paper cup is pockmarked, just like double adhesive paper, while the copperplate printing is relatively smooth. On the copperplate printing, there is coating for reflecting light. Therefore, there are two kinds of color cards on the printing, one is C-side, the other is u-side, C-side is smooth surface, and u-side is pockmarked surface. The color printed on advertising paper cup will be dimmer because of the pitted surface, which is not bright on the coated paper. So when you design, try to design a brighter one, which will make you feel better.

Due to the color of each picture taken into account on a board, the disposable paper cup customization will also produce a little color difference. The color difference of four color synthesis will be reduced as far as possible.
