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


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


The first is the order of the black ink. Since black ink usually contains a large amount of pigment and resin, if the color ink is printed first and the black ink is printed later, it may cause the black ink to cover the color ink, thus affecting the performance of the color ink. Therefore, in the printing process, the black ink should be printed first, so as to ensure the most accurate performance of the black ink on the print.


Next is the cyan ink. In the printing process, the cyan ink should be printed before the magenta ink because the cyan ink can be used to make a large number of blue colors. In the subsequent magenta ink printing, the blue color can also be used as one of the primary colors, so that the performance of the magenta ink is more saturated.


And then the magenta ink. In the printing process, the magenta ink should be printed before the yellow ink. Because if the yellow ink is printed first, the yellow and magenta colors will be mixed together in the subsequent magenta ink printing, thus affecting the performance of the magenta ink. If the magenta ink is printed first, the yellow and magenta colors will be mixed together in the subsequent yellow ink printing, thus making the performance of the yellow ink more saturated.


Finally, yellow oil.


The inking sequence of four-color printing CMYK has a great influence on the printing quality and printing speed. The following details in the printing process ink CMYK inking sequence.


First, the CMYK color model is a standard in the printing industry, representing the four color inks used in the printing process. C represents Cyan, M represents Magenta (Magenta), Y represents Yellow, and K represents Black (Key color). Among them, the black ink is obtained by mixing CMY three color inks, 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, that is, cyan, magenta, yellow and black. This inking sequence is called "forward inking" (Forward Direction) and is the most commonly used inking sequence. This inking sequence has the following advantages:


The black ink can cover the defects of the other three color inks. In the case of positive inking, the 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 the black ink can achieve a deeper color saturation with a smaller amount of ink, the printing time and the amount of ink used can be reduced, and the printing speed and economic benefits can be improved.

In the case of positive inking, a film is formed between inks of different colors, which makes it easier for the ink printed later to adhere to the paper, thereby improving the quality of the printed matter.

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


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