Correct adjustment of colors in graphic design and printing design
A qualified graphic designer should not only consider the design effect of his own piece, but also consider the effect after printing. Because the final effect of graphic design needs to be reflected by the printing machine to be reflected.
The highest level of design is to show the richest content with the least colors. The best graphic design is to adjust the film to the most suitable pre-press design for your production situation.
1. Color reproduction of offset printing
Offset printing is also known as offset printing. Therefore, whether the color of offset printing can be correctly restored has the most direct influence on the dots forming patterns on the printing plate (PS version). As long as the density of the dots of the pattern distribution is appropriate and consistent with the needs of the designed document dots, then basically no large color errors will occur.
The main factors that affect the accuracy of the dots during printing are the accuracy of the film screen, the exposure accuracy of the film during the printing, and the contrast of the gray scale of the PS screen. If you want to ensure that the printing effect reaches the pre-press design effect, you must consider the factors such as the dots designed by Film and the exposure of the printing plate, and whether it will cause the deviation of the printing color effect. Since the printing color is affected by the inking volume of the printing plate, and the inking volume is formed by the density of the dots, the dots are the key factor that affects whether the color can be accurately restored.
Second, the performance of graphic design and printing design
Graphic design is the preference of many young people. Graphic design is the basic skill of printing design. Printing design cannot be done without the foundation of graphic design. The basic principle of printing graphic design is that, in addition to the operation of graphic design software, pattern design of graphic design Skills, but also familiar with the basic structure of the packaging box, the basic functional requirements of the packaging box, the country's basic regulations on product packaging, etc. The simple graphic design is just a list of materials and common sense. For example, how to highlight the theme, how to set the main color of the color, how to reasonably arrange the various essential contents within a limited structure range, which expression form is suitable for the structure of the packaging box, etc. In addition to these basic skills, printing graphic design also needs to understand the basic common sense of printing, which is the basic condition necessary for printing. Some junior graphic designers who do not understand the basic common sense of the printing process often appear that the design looks very beautiful, but it is difficult to show the effect when printing. For example, can the color be accurately restored, can the size of the font be printed clearly, and can the pattern structure affect the accuracy of the overprint, etc. These problems are that the printing design must consider the principle of color restoration and expression in the printing process. It must be considered that the color in graphic design is a complete color, and all colors must be divided into red, yellow, and blue during printing The four basic monochrome colors of black and black are stacked on top of each other to restore the color. Therefore, pre-press graphic designers must understand how printed graphic design can turn their own design concepts and ideas into reality, and truly show that this is a qualified printed graphic design.
