Some problems that should be paid attention to in reducing printing costs

Mastering the plate making, printing process, and the printing price standard of each unit, understanding the paper specifications and performance is the most effective way to reduce the cost of books. The following will talk about how to effectively control printing costs from several aspects such as prepress production, printing, and binding.

Prepress production process to reduce the cost of printing should be considered

1. The correct choice of books. If the selection is unreasonable, it will reduce the effective use of paper and use more paper. If the cost is too small, the number of folds and light edge materials are also more. In order to facilitate the printing, as far as possible without or with less irregular copy, this can reduce the cost of printing.

2. The correct choice of paper material. Paper materials account for a large proportion of the cost of books, so the rational use of paper materials is an important aspect of reducing the cost of books.

In general, the papers used in different prints have different requirements and certain rules. For example, the texts of books and periodicals can generally use offset papers of 70 gm2/-80 g/m2, and the albums can generally use 128 g/m2 to 157 g/m2. Coated paper and so on. At the same time, it should also be noted that the heavier the grams of the same type of paper, the higher the price. As the weight of the text paper increases, the thickness of the spine also increases. Sometimes, the grammage and opening number of the cover sheet must be adjusted, resulting in a series of connected relations, which often increase paper costs.

In addition, the performance of the paper directly determines the quality of the book, and the better the surface performance of the paper, the higher the cost of the paper.

3. Reasonably determine the number of pages of the book. Because the printing format of the printing press is often a half-width or a half-width format, due to the needs of the printing industry, zero pages should be avoided during the typesetting process. Once a zero page is created, the fees will be increased, thus increasing the cost of printing. Since the binding process in the binding process requires a fee, the number of pages is preferably an integral multiple of 4 in prepress design.

Problems to Consider in Printing Process to Reduce Printing Cost

1. Reasonably choose paper specifications. Reasonable use of paper specifications can reduce the cost of books. First of all, different specifications of the paper, the number of individual pages will be different, for example, a large 32-key hardcover protective cover, spine thickness is about 40mm, if you use 787mmXl092mm size paper printing, a paper can be Out of 6, if you consider using 889mmXll94mm specifications of the paper, a sheet of paper out of 8. Secondly, when selecting different types of paper for printing, it is generally stipulated that papers with a size of 787mm×l092mm or more be used for printing at the price, and the fee will increase by about 10% to 30% when charging. Therefore, be careful when considering the size of books.

2. Reasonably choose the printing process. As the printing process, a variety of printing presses, such as BB machine, offset press, offset printing rotary press, etc., the printing method is also different. Therefore, in the prepress design should take into account the model used to determine the layout of the combination. Because different printing presses have different printing costs and the speed of printing is different, it can also be seen from the above examples that the speed of the rotary press is fast, and the printed book pages have been folded and the printing cost is much better than the sheet-fed printing press. The low.

On the other hand, the printing method of the printing press must also be taken into consideration. Because of the different printing methods, the printing costs are also different. If there is a 16-sheet print with both positive and negative sides, if it is printed in the normal printing mode, then there are 4 PS-versions on the front and back, 8 of which are printed and the printing fee is 8X80 yuan = 640 Yuan; If the reprint printing method is used, only four PS plates are required on both sides, and the printing fee on the sun is only 4X80 yuan = 320 yuan, which is half of the savings.

The printing personnel should understand the performance of various printing presses and the calculation standards for the wages. Otherwise, it may be possible to use high-cost and unreasonable printing processes to make the quality of books lower and the cost higher.

Stapling Process: Problems to Consider in Reducing Printing Costs

1. Bookbinding and layout considerations. The commonly used binding forms are saddle stitching, flat stitching, sewing thread binding, glue binding, and the like. Saddle stitching, staple stitching, and bookbinding can be designed to make the center-plate layout smaller. If it is a flat-book format, the layout of the center-page spread will have to be relatively large, because the flat book's mouth will occupy about 5mm. On the other hand, different binding forms have different standards for charging.

When designing manuscripts, the size of the body fonts, the density between lines, the width and width of blanks around them, and the line of headings and blank lines are all related to the number of pages in the typesetting of books. Once the number of pages in a book increases, the volume of books increases. The cost will also increase.

2. Reasonably determine the cover size. o When designing the cover, the design should be based on the finished product size, spine thickness, and size of the mouth. When designing the size of the mouth, it is generally possible to increase the size of the mouth slightly without wasting paper for printing. The majority is more than 30 mm, but some cover designers do not understand the paper specifications, the number of openings, and the performance of the printing press. When designing, the size of the mouthpiece is not fixed according to the opening number of the paper. After the platemaking, the paper size often does not meet the requirements of the paper specification opening number and waste is caused. Now most book covers need to be coated after printing, and thus the coating cost is increased.
