Reducing printing costs is a major priority for printing customers and printer salesmen. As a printing company that wants to save costs and save money for its customers, it must do the following things, including: Proficiency in film production and plate making ( Or directly out of the ctp, this can save the film out of this link), the printing process; understand the printing process costs, paper size and opening size. In addition, it is more important to consider "how to operate can effectively reduce the printing cost" from the typesetting.

First of all, we first understand the type of layout, and now use computer imposition, the following describes the typical typesetting:

The key to typesetting is to arrange page numbers. Regardless of the encoding method, the factors to be considered include the orientation of paper and finished products, the format, the printing method, and the post-press processing (binding method). Special attention should be paid to the fact that except for the 16-sided vertical and 32-sided lateral planes, the positions of the lateral planes are the 5th and 6th pages, and the rest are the 3rd and 4th pages, which is very important. Now the open format is left open, that is, odd numbers are on the right side of the back of the book. The following will analyze the individual instances.

The layout is generally divided into positive and negative versions. Bottom panel: single-sided printing or one set of printing side; self-reflection: two-sided printing share a set of version, flip paper does not change. Self-reflection is divided into two kinds of self-reflection and up-and-down self-replicating two kinds, to clarify the two self-reflection first clear the direction of the offset press paper.

This figure shows that regardless of the size of the offset press, the long edge of the paper is used as the feed direction. According to the figure, left and right self-reflection means that the paper is flipped right and left in the direction of the paper, and up and down self-reversal is to turn the paper up and down in the direction of the paper. For example: 16K, normal 8K prints will be left and right self-reflection when they are split and open.

The long strip 8K is an up-and-down self-reproducing version when it comes to quadruple version, and the spelling is left and right self-reflection.

The opening of a general offset press is 1 centimeter, so the left and right turn can guarantee that the printed product will go according to the normal size, and the upper and lower self-reflection will take 2 centimeters of mouthwash on both sides. Therefore, the finished product must be smaller in size. This is a must when designing. Need to pay attention. For example, for a 16K print product, the finished product requirement is 21.0×28.5 cm, after adding a hole, it is 21.6×29.1 cm, and the 4K version is 43.2×58.2 cm, and the maximum opening size of 4K paper is 44.4×59.5 cm. It can be seen that spelling left and right 4K version plus 1 cm acupuncture point does not exceed the paper size and can be printed normally. A long strip of 8K printed matter, if its finished product requirement is 21.0×57.0cm, 21.6×57.6cm after adding a hole, 4K version is 43.2×57.6cm if it is turned up and down, if there is a total of 2 on both sides In cm, the maximum open size of 4K paper is 44.4×59.5cm, so it cannot be printed. This requires us to clearly explain to customers after designing and manufacturing. After reducing the finished product size and acupoints, we can meet the printing requirements; This does not happen in the open edition.

Friends in the industry all know that the completion of each printing job requires a complete process: pre-layout design, proofing, finalizing, plate making, printing, post-processing, quality inspection, and packing. The early typographic design was at the top of the list. Based on this, we can understand that the typographic design has played the most primitive role in the control of printing costs. Below we discuss the issue in detail from the following perspectives.
