Jinan Packing Factory often encounters customers'sample clothes in their daily printing work. Some customers will ask us to print with sample clothes. The color of the products should achieve the same effect as the sample clothes. In this case, we can not give customers a positive answer. We can only guarantee that the sample is close to 90% at most, because the color of the printed matter is closely related to the following factors.
1. CMYK value of file
2. Ink Quality
3. Printer Length Operation
4. Air temperature and humidity
5. The influence of coating process on color
The first four factors have been elaborated in other articles. Here is the process of the influence of color on film-covered printing. Most printing machines need to go through this process, either covered with dumb film or covered with bright film; whether covered with dumb film or bright film, product color will deepen, especially after covered with dumb film.
In this case, at the beginning of printing, we can use sampling method to print a matte tape or optical tape on the surface. If the color is too dark or too light, let the printer try to increase or reduce the amount of red, yellow, blue, black and four-colour inks. Printing method basically coincides with the color of the printed sample. The color is similar to that of the printed sample. The degree can reach 90%.
