What Is Color Quality Control?

The so-called color management refers to the use of a combination of software and hardware to automatically and uniformly manage and adjust colors in the production system to ensure color consistency throughout the entire process. The CIE chromaticity space is used as the reference color space, and the color characteristics of the input or output of the device are recorded in the feature file. Application software and third-party color management software are used as the user's color control tool

Color management

Color management has two meanings: one is determined by the basic requirements of traditional color reproduction, that is, according to paper,

Management of color quality of industrial products. The content includes the selection of materials, testing, color measurement, judging whether the finished color is good or bad, limiting the allowable range of errors with color samples, color statistics and finishing. In various color materials, printing, finishing, dyeing, color TV,

The main goal of color management is to achieve color matching between different input devices, including various scanners, digital cameras, Photo CD, etc .; to achieve color matching between different output devices. include

To carry out color management, you basically need to go through three steps in sequence. These three steps are called "3C", that is, "Calibration" (characterization), Characterisation, and Conversion.

1. Calibration and characterization of input devices.

2. Calibration and characterization of displays.

ICC Introduction

In the printing workflow, many imaging devices are involved, such as digital cameras, scanners, printers,

An ideal color management process is as follows:

1) Determine the color performance characteristics of the display: some

Through efficient, predictable and mature color management, the ability of professional design can be enhanced to better achieve "

Color management color box

People find that the colors of the same item are not consistent when viewed under different light (metachromatic effect). In order to unify the lighting source, there is an international standard light source lighting box, which is a standard light source box. Color viewing and pattern making are all carried out in a standard light source box or a sample stand, so that there will not be any controversy in color management due to different light in cloudy, rainy, or day and night. Standard light sources are the most commonly used tools for visual colorimetric management of color.

Color management computer colorimeter

Computer color measuring instruments include color difference meter, printing dot density meter, screen brightness, gray meter and so on. The computer automatically measures the color value of the item, and then outputs the value for user's reference to digitally manage the color.

Third, the international standard color card

The color card is the most commonly used color management tool and is an internationally used color language. With the color card, people no longer need to describe the color and send samples, and directly report the number of a color card to unify the color of the items. The color card plays a huge bridge in color management.
