Color screen printing color sequential arrangement skills

Color screen printing color sequence is how to arrange?

Color screen printing color sequence arrangement is generally yellow, cyan, magenta, and black. Taking into account the process requirements, the order of the colors is also cyan, magenta, yellow and black. In foreign countries, black, yellow, magenta and cyan are also used for printing color sequences. Since the shapes of the substrates in screen printing are different (planes and curved surfaces) and the nature of substrates is different, the color sequence is also different. For example, When printing on transparent objects, the color sequence should be black, yellow, cyan, magenta. The arrangement of the color sequence has an important restriction relationship to reflect the original color. How to ensure that the color of the copy is not distorted, in addition to the correct use of the ink, it also requires long-term work practices and experience accumulation, to constantly explore and summarize.

Determine the screen printing color sequence to consider two factors, one of which is the transparency of the ink on the substrate, which is the main factor in the two factors. Since in the screen printing, ink of a new color is produced by mixing or superimposing inks of various colors, if the transparency of the ink on the substrate is poor, the ink of the first color will be covered when the second color is printed. It cannot be combined with the second color to create a new color. The second factor is that people’s eyes have different abilities to experience various colors. In general, people's eyes are most sensitive to magenta, followed by cyan and least sensitive to yellow. Because people have different color sensitivities, it often results in the expansion or reduction of yellow dots, the loss and the change in the size of ink, which can affect the printing quality.

The correct screen printing procedure and requirements are that the first color should be printed with a cyan version, and after printing, a contrast check of the gradation reproduction shall be performed with a step scale and a color scale. The second color is printed with a yellow printing plate, so that the two colors are laminated to form a green color, and then the human eye's ability to recognize the green tone is used to check the print quality against the scale and the color mark. The third color is printed in red, and the black version is used last. The black version enhances contours and dark levels. After the four-color version is printed, the same color copy as the original is obtained.
