Disposable paper cups are widely used in our lives. Many manufacturers like to print the words or patterns they want when they order paper cups. Customers often respond to printing with color difference after purchasing paper cups. In order to avoid the seriousness of chromatic aberration, paper cup printing manufacturers should pay attention to the printing matters:

1. Try not to make paper cups for design and use full-color paper cups.

The full-color paper cup ink is overfilled, and the paper cup is produced and sealed directly. The organic compounds emitted by the solvent ink during the drying process, the isopropanol in the alcohol moisturizing liquid, and the volatile gas of the glazing coating are all harmful to human health. In the sealed space, the full color of the paper cup covers the entire body. When we use the paper cup to drink water, the lips will touch the mouth of the cup. It is easy to bring the above chemicals together with the liquid. The body affects your health. Therefore, we generally recommend that customers should not design a full-color color when designing and making paper cups, and the smaller the color, the better. It is also not appropriate to design graphics near the mouth of the cup, especially block ink. Otherwise it will have the same bad effect.

2. The strip shape near the bottom of the cup should be raised by 5mm.

Because the cup is placed on the machine, the bottom of the cup should be pressed 5mm to ensure the firmness of the bottom of the cup. However, the high temperature and pressure of the machine can easily make the pattern and text close to the bottom of the cup and affect the appearance. Therefore, the character strip pattern near the bottom of the cup when designing and making the pattern should be raised by about 5 mm according to the height of the bottom of the cup.

3, the color displayed on the LCD computer, we all found that the color is not the same from all angles, so many customers think that the color they see, print out the effect, in fact, in a completely different color.

4, paper cups below 100,000 are all imposition production, because one version considers the color of each picture, it will also produce a little color difference, try to reduce the color of four-color composite printing will reduce the chromatic aberration.

5, as little as possible four colors superimposed, if CMYK four colors superimposed, that stacked out, most of them are black, like the registered color, CMYK39393939, try to superimpose the two primary colors, if you must have four colors superimposed, the color requirements are relatively high, Please proof. The coloring sample is a method of printing by the way when printing a cup.

6, people who use computers now are LCD monitors, 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 very different from the printing, there are many colors The display of the print is almost completely different, because the LCD display uses the RGB mode.

7. The paper used for paper cups is pockmarked, just like double-adhesive paper, while the copper plate printing is lighter. On the copper plate printing, there is coating for reflection, so there are two kinds of color cards on the printing, one is C-side. One is the U-face, the C-side is the glossy surface, and the U-face is the matte surface. The color printed on the paper cup will be dimmed because it is a pockmark, and there is no brightening on the coated paper. So when you design, the design is brighter, so it feels better.
