Knowing these box printing common sense, saving half of printing costs

The invention of ancient printing technology has enabled the rapid development of human civilization, which has led to the vigorous development of culture and art. It is important to make this world more colorful. In today’s society, the rapid development of science and technology has made the printing industry more qualitatively transformed. The birth of various printing technologies has made our lives more colorful.

Printing companies and customers alike hope to produce beautiful products, not only the technical requirements of the printing plant, but also the cooperation of the customers. So the more you know about printing, the more you can help us reduce the variety of possible problems. Speed up the delivery process to avoid increased costs or delays.

The color box printing company, Shenzhen Printing Factory, said that the printing is simple, it is divided into three parts; layout design, film printing, post processing.

The common problems that should be noted are the following:

First, printing common paper:

Coated paper, offset paper, newsprint, etc. (The difference in printing materials will also make the printing effect different. Generally speaking, the printing effect of coated paper is much brighter than that of offset paper, and some special printing materials should use special paper.)

Second, the difference in chromaticity between film, proofing, print and computer screen

Film and the corresponding proofing are the best choices to reduce errors and save you time with us. The proof corresponding to the film is closest to the printed product (close to 95%). The printed effect displayed on the computer screen is much brighter than the actual printed product, and cannot be used as an equivalent reference. Therefore, it is subject to the printing proof. This is because the display is quite different from the color of the color paper.

The display uses the three primary colors of red, green, and blue to emit light to form an image. This principle of color formation is called RGB. Color printing is the printing of red, yellow, blue and black inks on paper products to form a color image. This principle is called CMYK. Another important reason is that even if the files are in CMYK mode, the color standards of each display are different, and the colors they display are also different. According to the national standard for printing color values, 90% is the standard finished product.

Third, the post-printing processing includes:

Folding, die cutting, nailing, laminating, oiling, UV, bronzing, drumming, coding, etc. The accuracy of the post-printing process is less than 100%. According to the state, the processing error of printed matter is not more than 0.2 mm.
