the composition of the printing color, how the printing color is presented, and the detailed explanation of the color

printed matter is divided into monochrome printing and color printing. monochrome printing is a printing method limited to one color. Color printing can print full-color pictures. Color printing mostly uses color separation plates to reflect various hue, and color separation plates are mostly red (M), yellow (Y), blue (C) and black (K) four-color network cable version. The hue of the color separation version can be based on the principle of color separation, and the dot number of CMYK in the chromatography can be directly marked with words. When special colors are needed, special colors other than these four colors must be used to set a spot color version. The color logo of the spot color version can specify a certain hue in the chromatography for special debugging.

printing color representation

ink printing color, there are generally two methods:

(1) Printing colors, mixed dots and overlapping printing using four-color inks.

(2) Mix printing inks to prepare spot colors, I .e. use spot colors for printing and use solid colors or dots to express colors. The color designation and plate-making methods of the two methods are different in the printing design.

1. In gray-scale monochrome printing of monochrome printing, the deepest real bottom is 100%; White is 0%, during which different deep and light gray is made by calling different dots, I .e. using percentage control. In order to facilitate reading, reverse white characters are usually applied to dark gray tones from 50% to 100%, while black characters are used between 50% and 0%, but they should also be considered according to different monochrome.

2. Four-color marking for color printing Color printing uses red, yellow, blue and black four-color printing to produce ever-changing colors. It can use color separation and plate making to print colors. However, the desired color of text or graphics in the design can be used to check the CMYK value of each color. However, some special colors such as gold, bank and fluorescent colors cannot be overprinted with four-color inks, and must be printed with spot-color inks.


Change of Color Edition

modern design are diverse and varied. In order to express a more perfect artistic conception or a more special effect, only restoring the color of some original images cannot meet the required requirements. Therefore, the color plate process can be used to change or convert the order and quantity of color plates to meet the special color design requirements.

1. Turn the black and white feature into two colors.
uses two sets of color plates, and uses a monochrome printing machine to print twice, or a color-changing printing machine to complete once. Two-color printing usually uses a single-color black plate, and then takes another color as the color tone to combine printing. When the original effect is not very good, this two-color printing method often produces unexpected effects.

2. Color plate replacement printing
color plate replacement printing is in the printing design, a certain color plate is exchanged, resulting in color plate changes. The purpose is to pursue special picture effects, which can often bring unexpected effects. Among the four color separation versions, if the two or three colors are interchanged and printed, the tone of the entire original surface will be changed, causing great changes. For example, the green tree is composed of yellow, blue and a little black; if the yellow version is changed to red printing, and the blue version remains unchanged, the green tree will become purple. A similar approach is used in some poster designs and The occasional use in layout design will get novel effects.

color positive film to two colors is to separate two of the four editions, and only two editions are printed, that is, two-color printing. A third color can be produced. For example, blue and yellow can be mixed to obtain green. As for the depth of green, it completely depends on the ratio of the dots between blue and yellow. A color picture is produced in a normal tone and printed in two color plates to achieve special color effects.

in the design, the occasional use of this printing method will produce a fresh feeling. When applied to the performance of the environment, atmosphere, time and season of the scene, it can have a special creative effect.

In order to seek a special tone effect, one of the four-color printing can be separated and the three-color printing can be retained. In order to make the picture effect clear and prominent, the three colors often use the heavier and darker version as the main color.

can also print one of the three editions as a spot color. For example, making the black plate into silver or gold will produce a special color combination. Using the technique of color plate transformation, it is suitable for exaggeration, emphasis and special effect treatment.

3. Monochrome Printing
monochrome printing refers to the use of one-plate printing, which can be black printing, color printing or spot color printing. Special color printing refers to a special color required in the special modulation design as the primary color, which is completed by one plate printing. Monochrome printing is widely used, and will also produce rich colors to achieve satisfactory results. In monochrome printing, color paper can also be used as the background color. The printing effect is similar to two-color printing, but it has a special charm. Special colors Special colors include glossy printing and fluorescent printing.
gloss color printing mainly refers to printing gold or silver. To make spot color plates, gold ink or silver ink is generally used for printing, or gold powder, silver powder, bright oil, quick drying agent, etc. Under normal circumstances, it is best to lay the bottom color for printing gold and silver. This is because gold or silver ink is directly printed on the surface of the paper, which will affect the luster of gold and silver ink due to the oil absorption degree of the paper. Generally speaking, a certain tone paving can be selected according to the design requirements. If you require golden hair, warm color and luster, you can choose red version as the bottom color; otherwise, you can choose blue; if you want to be deep and shiny, you can choose black bottom. Fluorescent color printing refers to the use of spot color printing fluorescent color, the use of fluorescent ink printing, because of the different properties of the ink, the printed color is extremely dazzling and bright. Used in design works, it can produce distinct and unique effects.
