The importance of issues such as printing color quality

Many companies have lost important customers because of color quality problems. However, in the printing industry today, we will find that our eyes' ability to identify colors becomes increasingly unreliable after being affected by differences in light sources, work environment, and human eyes. Therefore, we should establish a standard color environment. .

The so-called Color Management System (ColorManagementSystem), through scientific and digital methods, corrects various devices, and records the device's color characteristics in the “profile” to obtain predictable colors on the device. Reproduced in different output environments.

The print effect will be different. In order to perform accurate color space conversion and color matching, system devices must be introduced. 1. Implement color management on the display We usually use an ICC profile in the computer we use, so the color display is the easiest to characterize and generate the profile file. The user can manually adjust the display and the graphics card so that the display and the graphics card communicate with each other, and the operating system is used to represent the color image. 2. Implementing color management scanners and digital cameras for scanners and digital cameras involves additional issues. The scanner usually comes with software to control the imaging, but any adjustment should be able to enter the operating system, and then enter the color management software. Implementing a color management printer can be said to be the most difficult part of a color management system, and its principle is a subtractive color method. The so-called subtractive method refers to the mixing of pigments and pigments, and the more the mixed colors become darker. Cyan (C), magenta (M), and yellow (Y) are the three primary colors of the subtractive method. Theoretically, when the three primary colors are completely mixed, they become black. However, because the ink contains impurities, it does not appear pure black when printed, and it becomes Thick and turbid color. Therefore, the black ink (K) is added during printing, and it becomes four colors, which not only represents the pure black primary colors, but also reduces the total ink usage. The same is true of printers.
