How Publishing Houses Improve Print Quality

The book quality includes the book's content quality, design quality and printing quality. The high-quality design and printing level can attract people's attention and enhance their trust in the contents of the books. It will eventually become a decisive factor in buying behavior. The printing of books belongs to the appearance and production of books. A good appearance can better express the content and promote the expression of the content; a bad appearance can not express the content well and have a negative impact on the content.

The book is divided into two phases. The former phase belongs to the design and preparation stage of the book and works in the publishing house; the latter stage belongs to the production stage of the book and works in the printing enterprise. The publisher is responsible for the content quality, editing quality and design quality of the book. : The printing house is responsible for the book binding quality.

First of all, prepress production is the process of processing the original into a printing plate that can be printed and reproduced according to the overall design requirements of the book. The prepress process includes document verification, text input, graphic editing, graphic output, plate production, and proofing. When checking the originals of scientific and technical books, the quality of the illustrations (including color pictures, black-and-white images, line drawings, etc.) should be inspected. Color and black and white image artwork must have clear images and strong sense of hierarchy. The color should be bright; the lines of the line drawing should be clear and full; the resolution must meet the publishing requirements, and the line number must be above 300 l.

Since most of the manuscripts handed to the publishing house by the author are manuscripts, some pictures are processed by them. If the illustrations do not meet the requirements, the publisher must promptly inform the authors to provide better pictures or remake. For the color pictures provided by the author, often use professional drawing software such as Photoshop software, for morphological transformation, color transformation, level correction, image modification, special effects design, screening and other processing methods. Many of the line drawings in the manuscript are scanned by the author from other materials or books. Such pictures are generally redrawn with the corresponding graphics processing software (such as Freehand, CorelDRAW, etc.). If the picture is saved, it will not meet the requirements. The illustrations are brought to the printing stage and are bound to affect the printing quality.

Followed by the determination of the printing process. Publishers should work with printing companies to choose reasonable printing processes to achieve the best printing effect. Book printing generally uses lithographic printing, and the inner core printing (monochrome) generally has no special requirements in the process. For the binding production, the publishing house often uses some special processes, such as coating (light film, matte film), UV coating. , embossing, special printing, etc. The use of these special processes has its own specific objects and conditions. These factors must be taken into consideration when designing a frame. If improper selection is made, the printed version will not achieve the desired effect.

Again, the choice of printed materials. The materials printed by the book mainly refer to ink and paper. Publishers generally pay less attention to printing inks, and they pay more attention to the papers that affect the cost of printing. With the same printing press, using different grades of quality paper, the printing quality is very different. Therefore, the publishing house should select different printing materials according to the different requirements of the book. The key books and boutique books can be considered for selecting high-grade paper and specialty paper, and ordinary books are selected for plain paper.

Finally, talk about the press's supervision and management of the book printing process. You can take the following measures:
1. When selecting fixed-point printing companies, their qualifications, printing equipment, personnel quality, management level, etc. shall be inspected, and the printed quality of printed documents printed by all fixed-point printing enterprises shall be analyzed regularly and irregularly.
2. Go deep into the printing company's workshop, check the printed books, understand the progress of the decals, and promptly identify quality issues so that measures can be taken to improve and remedy the problems.
3. Adhere to the sample book review system before book binding. The "Quality Assurance System for Books" clearly stipulates: "The printing house must first staple 10 copies of the sample book and send it to the publishing house for inspection before the front cover of each book has been printed and the contents have not been bound in batches." Cause unnecessary losses.
4. Sampling a large quantity of printed books submitted by the printing factory. In addition to checking the sample books sent by the printing house, it is also necessary to conduct sampling inspections on large quantities of books based on the number of decals and printed books. For unqualified books, they will not be signed for storage.

In summary, under the conditions of market economy, publishers have a greater responsibility for improving the quality of book printing, and should be the main body of book printing quality management. Therefore, in addition to the prepress production of books, It is necessary to strictly manage the books printed by printing companies. In order to solve the problem and communicate with each other, take responsibility for each other, work in close cooperation, and work together to improve the quality of the book's printing and installation, and provide readers with excellent and unified books and contents.
