In the printing process, the ink CMYK inking sequence is very important. The correct inking sequence can ensure accurate color, high color saturation, and natural color transition of the printed matter, while the wrong inking sequence may lead to inaccurate color, unnatural color, and even affect the quality of the entire printed matter. This article will introduce the ink CMYK inking sequence during the printing process in detail.

CMYK is the four most common colors in the printing field. C stands for cyan (Cyan), M stands for magenta (Magenta), Y stands for yellow (Yellow), and K stands for black (Key plate). These four colors can be mixed to create all the colors in the print. During the printing process, the ink sequence should be K, C, M, and Y.

The first is the inking sequence of black ink. Since black ink usually contains a lot of pigments and resins, if you print color ink first and then black ink, it may cause black ink to cover the color ink, thus affecting the performance of the color ink. Therefore, in the printing process, black ink should be printed first, which can ensure that the black ink performs most accurately on the printed matter.

Next is the cyan ink. In the printing process, the cyan ink should be printed first than the magenta ink because the cyan ink can be used to create a large number of blue colors. In subsequent magenta ink printing, the blue color can also be used as one of the primary colors, thus making the magenta ink more saturated.

Then there is the magenta ink. In the printing process, the magenta ink should be printed first than the yellow ink. Because if the yellow ink is printed first, then in the subsequent magenta ink printing, the yellow and magenta will mix together, thus affecting the performance of the magenta ink. And if the magenta ink is printed first, then in the subsequent yellow ink printing, the yellow and magenta will mix together, thus making the yellow ink more saturated.

Finally, yellow oil.

The inking sequence of four-color printing CMYK has a great impact on the printing quality and printing speed. The following describes the inking sequence of ink CMYK during the printing process in detail.

First of all, the CMYK color mode is a standard in the printing industry, representing the four color inks used in the printing process. C stands for cyan (Cyan), M stands for magenta (Magenta), Y stands for yellow (Yellow), and K stands for black (Key color). Among them, the black ink is obtained by mixing the three color inks of CMY, so it is called "Key color" (Key color), referred to as K.

For four-color printing, the inking sequence is usually C-M-Y-K, which is to print cyan first, then magenta, then yellow, and finally black. This inking sequence is called "Forward Direction" and is also the most commonly used inking sequence. This inking sequence has the following advantages:

Black ink can cover the defects of the other three color inks. In the case of positive ink, black ink is finally printed, which can correct the defects of the first three color inks and ensure the quality of the printed matter.

Since black ink can achieve deeper color saturation with less ink, it can reduce printing time and ink usage, improving printing speed and economic efficiency.

In the case of positive ink, a thin film is formed between different colors of ink, making it easier for the ink printed later to adhere to the paper, thus improving the quality of the print.

In addition to the forward inking sequence, there is also a reverse inking sequence, also known as K-Y-M-C. This inking sequence is called "Reverse Direction" and is generally only used in special circumstances. The reverse inking sequence has the following disadvantages:

In the case of reverse inking, black ink is often printed first, which means it needs to withstand the pressure of the first three color inks. Due to the special nature of black ink, this will cause it to not fully cover the previous color, thus affecting the quality of the print.
