Various color modes for color box printing are also interrelated, and there are three modes in total. The first is the RGB mode, the second CMYK mode is composed of green, green and blue light, and the yellow and black four-color inks are used in color box printing. It consists of red, green, and blue light. Composition, it is mainly used on the display screen, so it is also called color light mode, which is not suitable for color paper box printing, so it is also called pigment mold, the usage of each ink ranges from 0% to 100%, and more colors It is produced by mixing CMY inks, which add up to red, green and blue.

Because the three SMY inks cannot form pure black when printing in color boxes, a separate black ink K is required to form the color pattern of CMYK. The larger the ink quantity in the printing factory, the heavier the color, the darker the opposite color, the smaller the amount of ink, the brighter the color. Knowing the basic color tone of the print above, you should check the file when the customer gives us the file, so the CMYK mode Called subtraction, the laboratory has another mode, which is a light-colored theoretical recording mode. This mode does not emphasize here because it has a small conflict with our printing method. Let's see how different it is from the color values we print. Generally, there are two reasons for color distortion: when color recovery processes distortion, because we mentioned above, the other is color processing distortion. As mentioned above, color Box printing usually reproduces the color and C, m, y, and K four-color inks. Due to the purity of the ink itself, color box printing will also produce color distortion. If it is in RGB format, we will be converted to SMYK for publication.
