Arrange The Printing Color Sequence To Print The True Color Of The Original

      In color printing, how to reasonably arrange the color overprint sequence is an important topic for process technicians. An important role of printing is to copy the original artistically, which requires printers to have a certain artistic appreciation and the ability to master the expression of color changes.Arrange The Printing Color Sequence To Print The True Color Of The Original

      Improper color sequence arrangement may lead to color deviation, color mixing and reverse overprint of printed matter; Scientific color sequence arrangement will make the color of printed matter closer to the original, and even strengthen a certain color atmosphere, so that the level is clear, the dot is clear, the overprint is accurate, and the color is real, natural and coordinated.Arrange The Printing Color Sequence To Print The True Color Of The Original

Arrange The Printing Color Sequence To Print The True Color Of The Original

      There are three reasons for the arrangement of color sequence: the influence of ink overprint and the shortcomings of ink pigment itself, the quality of paper and the ability of human eyes to recognize color.Arrange The Printing Color Sequence To Print The True Color Of The Original

      The most fundamental reason is the incomplete transparency of the printing ink itself, that is, the hiding power of the ink itself. The ink of post printing has a certain covering effect on the ink layer of pre printing, so that the color of printed matter always focuses on the performance of the latter color, or the mixed color of post color and pre color.Arrange The Printing Color Sequence To Print The True Color Of The Original

      The starting point of selecting color sequence is to flexibly arrange the color sequence according to the specific situation of the original and combined with the current process conditions, taking into account the main aspects (such as tone reproduction, color reproduction, graphic clarity, printing uniformity and printing repetition rate, etc.).

      The following principles of arranging color sequence are for the reference of peers.Arrange The Printing Color Sequence To Print The True Color Of The Original

       Arrange the color sequence according to the content and characteristics of the original. Printing is a means to express the graphic design of the layout, and the emotional components embodied in each color are also different.Arrange The Printing Color Sequence To Print The True Color Of The Original

       Therefore, the arrangement of color sequence must first consider the content and characteristics of the original. When designing graphic layout, editors often have chosen the tone of layout color.

       This tone represents the overall feeling of the whole tone and becomes the dominant color in printing. In terms of color, those based on red, orange and yellow are called warm tones; Green and blue are called cool tones.Arrange The Printing Color Sequence To Print The True Color Of The Original

      Due to the hiding power of the ink, the warm tone is generally printed first in black and green, and then in magenta and yellow; Magenta is printed first and cyan is printed later.

      Everyone wants the ripe watermelon pulp to be red, and doesn’t want to see the printed matter show purple and green. The effect of color deviation is different with different color order.     

      Therefore, the color that needs to be strengthened in the picture color atmosphere can be printed in the last color.Arrange The Printing Color Sequence To Print The True Color Of The Original

      Arrange the color sequence according to the transparency of the ink. For the ink with good transparency, after two colors are superimposed, the color light of the lower ink layer can pass through the upper ink layer to achieve better subtractive mixing and show the correct new color.

      If the yellow ink used is transparent yellow, the transparency order of the four inks is: Yellow > magenta > Green > black. Generally speaking, the ink with poor transparency is printed first, and the ink with good transparency is printed later.Arrange The Printing Color Sequence To Print The True Color Of The Original

       Arrange the color sequence in favor of overprint. Due to the objective defects such as paper deformation and expansion, we can arrange the main colors of overprint prints with high requirements to be printed in two adjacent color groups. For example, the two-color machine can be arranged to complete printing at one time in the same unit to avoid problems such as paper expansion and contraction caused by paper. Arrange The Printing Color Sequence To Print The True Color Of The Original

      For large-scale field, post printing can be arranged to avoid problems such as rubbing and dirt in the process of paper handover. In addition, the monochrome machine overprints the second color after the first color is “dry”, while the multi-color machine is a “wet pressing wet” process, so the viscosity and amount of ink should be controlled.

      That is, it is very important to arrange the ink with high viscosity to be printed first and the ink with low viscosity to be printed later, otherwise it will cause the disadvantage of reverse overprint.Arrange The Printing Color Sequence To Print The True Color Of The Original

       Arrange the color sequence considering the nature of the paper. For poor quality paper, considering its low whiteness and smoothness, loose fiber, poor ink absorption, easy to lose powder and hair, yellow ink can be printed first to make up for the above defects of the paper.

      When printing at night, weak color ink with low lightness should not be printed in the first color due to the recognizability of human eyes. The brightness order of ink is: white < yellow < orange < green < green < red < blue < purple.Arrange The Printing Color Sequence To Print The True Color Of The Original

5. Consider plate making and other process factors. When printing, the screen wire angles of two adjacent color groups differ by at least 30 °, which is conducive to preventing color deviation, moire and other disadvantages.Arrange The Printing Color Sequence To Print The True Color Of The Original

6. Consider color sequence arrangement according to cost. Cheap black and green inks are printed first, and high price magenta and yellow inks are printed later.Arrange The Printing Color Sequence To Print The True Color Of The Original

       Generally, the picture dominated by a large area of scenery (cold key as the tone), with black, magenta, green and yellow as the color sequence. Black is arranged to be printed first, and black is used to draw the outline for overprint of other colors. The final printing of transparent yellow can be used to adjust the brightness of the whole picture to form shiny and bright colors.Arrange The Printing Color Sequence To Print The True Color Of The Original

        Generally, the picture (warm tone) dominated by characters adopts the sequence of black, green, magenta and yellow. The ink with poor transparency will not cover other colors. Magenta and yellow back prints make the characters’ faces ruddy, colorful and realistic.Arrange The Printing Color Sequence To Print The True Color Of The Original

      Color printing is a combination of technology and art. When we arrange the printing color sequence, we can make the printed matter more artistic appeal and meet the needs of readers from the perspective of art.Arrange The Printing Color Sequence To Print The True Color Of The Original
