How to control the printing quality of books by th

As we all know, book quality includes book content quality, binding design quality and printing quality. With the improvement of people's living standards, people have not only paid attention to the quality of the content when buying books, but also whether the books are beautiful, that is, the binding design and printing quality of books (for convenience, we call it printing quality for short) have also become a very important standard for them to measure the quality of books. High quality design and printing can attract people's attention and enhance their trust in book content, which will eventually become the decisive factor in purchasing behavior

the printing quality of books is also an indispensable factor to evaluate the quality of books. Content and form (appearance) are two major elements of books. The printing of books belongs to the appearance production of books. Good appearance can better express the content and promote the expression of the content; On the contrary, bad appearance is not 4 It can express the content well when loading, which will have a negative impact on the content

then, who will guarantee the printing quality of books? Since the formation of books is divided into two stages, the former stage belongs to the design and preparation stage of books, working in the publishing house, and the latter stage belongs to the production stage of books, and working in the printing enterprise, it is generally taken for granted that: the publishing house is responsible for the quality of books' content, editing and editing quality and binding design quality; The printing factory is responsible for the printing and binding quality of books

in the era of movable type printing, after the publishing house's manuscript is published, the remaining publishing tasks are handed over to the printing house, which is responsible for the inspection, typesetting, proofreading, plate making, printing and other work. The printing quality is basically irrelevant to the publishing house. Nowadays, the prepress production stage of books is basically realized through computer typesetting software, binding design software, laser Phototypesetting, and the system that human skin has the ability to repair itself. The vast majority of publishing houses are equipped with relatively complete electronic publishing systems

because prepress production brings text and images into the whole printing workflow, it plays an extremely important role in the whole printing process, so publishers have an unshirkable responsibility for the printing quality of books. In addition, the work of publishing houses in many other aspects will also have varying degrees of impact on the printing quality of books. Therefore, as the main body responsible for pollution control, the printing quality of books is no longer the business of printing enterprises. Improving the printing quality of books has become a common goal for publishing houses and printing enterprises

this paper intends to analyze many factors affecting the quality of book printing from the perspective of Publishing House's management of book production, so as to provide working ideas for publishing house to improve the quality of printing

first, let's talk about the prepress production stage

prepress production refers to the process of processing the original into a printing plate that can be printed and copied according to the overall design requirements of the book. The prepress process includes original check, image and text input, image and text output, plate making and proofing. When checking the originals of science and technology books, we should focus on the quality of illustrations (including color drawings, black-and-white image drawings, line drawings, etc.): color drawings and black-and-white image drawings must have clear images and strong sense of hierarchy, among which the color of color drawings should be bright; The lines of the line drawing are clear and full; The resolution should meet the publishing requirements, and the number of lines must generally be more than 300L. At present, most of the manuscripts submitted by the author to the publishing house are disk manuscripts, and some drawings have also been processed by them. If the illustrations do not meet the basic requirements, the publishing house should notify the author in time to provide better drawings or make new ones. For the color pictures provided by the author, professional drawing software such as Photoshop software of adobe company in the United States is often used to carry out morphological transformation, color transformation, level correction, image modification, special effect design, color addition and separation and other processing methods. Many of the line drawings in the disk manuscript are scanned by the author from other materials or books. This kind of drawing generally needs to be redrawn with the corresponding graphics processing software (such as freehand, CorelDRAW, etc.). If the drawing saves trouble and brings the unqualified illustrations to the printing stage, it is bound to affect the printing quality

the second is the determination of printing process flow. Publishing houses should work with printing enterprises to select reasonable printing technology to achieve the best printing effect. Book printing generally adopts lithography, and inner core printing (monochrome) generally has no special requirements in terms of technology. For binding, publishing houses often adopt some special processes, such as film covering (light film, dumb film), UV glazing, embossing, special printing, etc. The use of these special processes has its specific objects and conditions. These factors must be considered in the binding design. If the selection is improper, although the printing cost is increased, the desired effect cannot be achieved

again, the choice of printing materials. The materials of book printing mainly refer to ink and paper. Publishers generally pay less attention to printing inks, while they pay more attention to papers that have a greater impact on the price of printing costs. The same printing machine uses different grades of paper, and its printing quality is very different. Therefore, publishers should choose different printing materials according to the different requirements of books. High grade paper and special paper can be considered for key books and excellent books, and ordinary paper can be selected for general books

finally, let's talk about the supervision and management of the publishing house on the book printing process. The following measures can be taken:

first, when selecting designated printing enterprises, we should conduct a detailed investigation on their qualifications, printing equipment, personnel quality, management level, etc., regularly and irregularly analyze and compare the printing quality of books printed by all designated printing enterprises, and encourage, praise and even increase the printing price of those with high printing quality; If the printing quality is not high and there are often problems after comprehensive and multi-level energy-saving technological transformation, we should give reminders and warnings, reduce the printing price, and even stop cooperation

second, often go deep into the workshop of printing enterprises to check the printed books, so that we can not only understand the progress of the commissioned books, but also find out the quality problems in time, so as to take measures to improve and remedy as soon as possible

III. adhere to the sample book review system before Book batch binding. The book quality assurance system clearly stipulates that "the printing factory must bind 10 sample books and send them to the publishing house for inspection before printing the cover and text of each kind of book and before binding them in batches." In this way, the relevant people of the books commissioned for printing can review the quality of the books before a large number of copies of the books, find problems in time and correct them, so as to avoid unnecessary losses

IV. spot check the large quantities of commissioned books delivered by the printing factory. In addition to checking the sample books sent by the printing factory, we also need to spot check a large number of books according to the number of books commissioned for printing. Books that fail to pass the sampling inspection will not be signed for warehousing. Because the sample books are generally carefully selected by the printing factory, if the publishing department only checks the sample books, and does not sample a large number of books, it is likely to let unqualified books flow into the library

to sum up, under the conditions of market economy, publishing houses have a greater responsibility to improve the quality of book printing, and should become the main body of book printing quality management. Therefore, in addition to carefully pre press production of books, they should also strictly manage the books printed by printing enterprises. Only by communicating with them with a problem-solving attitude, taking their respective responsibilities, cooperating closely and making joint efforts can we improve the printing and binding quality of books and provide readers with excellent books with perfect and unified content and form.
