RGB color mode for digital printing patterns

July 07, 2021

For digital printing, there are many principles that cannot be mastered in a short period of time. If you want to become an engineer in the textile printer industry, you also need to understand a lot of mechanics, mechanics and chromatics related mechanisms, so that you can use the equipment printing process. After the problem occurred in the medium, the problem was solved quickly. Friends in the printing industry know that the color of the pattern is the biggest explanation of the company to the customer. Today, I will share with you the RGB color mode of the digital printing pattern.

Generally, the actual effect of textile inkjet printing is quite different from the effect displayed on the computer screen. This is not only related to the fabric and ink used, but also an important reason for the different color modes used by the monitor and the inkjet printer.


In color science, the color representation method is called color model or color model. The color model is used to describe the colors seen and processed by the human eye. Use numerical values ​​to represent Xeno. Different color modes have different methods of describing and classifying colors.


The color range generated by a specific color mode is called the color space. The color model determines the relationship between values, and the color space defines the absolute meaning of these values ​​as colors. Some color modes have a fixed color space (such as L*a*b* and XYZ), which are directly related to the way the human eye perceives colors, so they can be regarded as device-independent; while other color modes (such as RGB, HSL) , HSB, CMYK, etc.) may have many different color spaces, which are different for each related color space or device, so they are regarded as device-related.


For example, the RGB color model has multiple color spaces, such as ColorMatch, Adobe RGB, sRGB, and ProPhoto RGB, and the same RGB color can be used to describe the configuration files of different RGB color spaces. The color display effect in each color space is different, but the value and mode can still be the same.

RGB color mode:


RGB color mode is also called RGB color space, which is a color rendering mode based on colored light. In nature, almost all colors can be synthesized from three colors of R (red light), G (green light), and B (blue light) through different ratios and intensities. Therefore, the International Commission on Illumination (CIE) stipulates that R, G, and R are the three primary colors of colored light. It is an additive color mixing mode, with different sizes of the three values ​​of channel R, G, and B, which can describe any color. RGB color mode is the most widely used color mode in color light mixing.


The RGB color mode assigns an intensity value of 0 to 255 for the RGB component of each pixel in the image. 0 means no stimulation, 255 means the stimulation amount reaches the maximum. The higher the primary color value, the brighter the color. For example, when R=255, G=0, B=0, it is pure red; when R, G, and B are all 0, it is black; when R, G, and B are all 255, it is white. When the three values ​​of R, G, and R are equal and are between 0 and 255, the mixed color is gray with different brightness levels.


When the three values ​​of R, G, and B are not equal to each other, the mixed color is color. The three primary colors are mixed in non-directional proportions, and 16.7 million possible colors can be displayed on the screen.


When editing images, the RGB color mode should be the best choice. Because it can provide a full-screen color range of up to 24 bits, it is called "True color" by color experts in the computer field. In addition, televisions, projectors, electronic display screens, etc. generally also use the RGB mode. In all image software, the RGB value can be set directly. Some software also provides an intuitive "RGB three-dimensional color mode" to set the RGB color value.


There are many different types of RGB color spaces. sRBG stands for "standard RGB color space", which was jointly formulated by Microsoft and HP in 1997. It reflects the average characteristics of PC monitors and is supported by many hardware manufacturers and software developers. It has gradually become many scanners, low-end printers and software. The default color space. sRGB is the narrowest of all RGB color spaces. Devices using the sRGB color space can simulate each other's colors, but this is achieved by sacrificing color range.

"Apple RGB" is the color space developed by Apple in the early days for Apple displays. It is used by the early-developed Apple publishing application software. Its color range is not much larger than sRGB. Because this kind of display has been rarely used, this standard has been phased out.


"Adobe RGB" was formulated by Adobe in 1998 and is called SMPTP-240M. It has a very wide color range, and most of its colors can be displayed on the device. This color space includes the entire color range of CMYK, can better restore the color of the original, and is widely used in the field of publishing and printing.


"ColorMatch RGB" is a color space defined by Radius, which matches the native color space of the company's Pressview display. "Wide Gamut RGB" is defined by the three primary colors of pure spectrum and has a wide color range. The color gamut of this space includes almost all visible colors, which is wider than the color gamut that a typical display can hardly display.


However, since many colors in this color range cannot be accurately reproduced on RGB displays or printing, this color space does not have much practical value.


Although the RGB color model is straightforward, there is no direct connection between the R, G, and B values ​​and the three attributes of color (brightness, hue, and saturation), and cannot reveal the relationship between colors. Therefore, when designing color matching, the RGB mode is not so suitable.
