Reasons for low printing quality of books and periodicals
There are many factors that cause the low quality of printing and packaging of the above books and periodicals, among which outdated equipment is an important reason. The quality of raw materials is poor and the technical level of workers is low. The most important reason is that the publishing management department has a weak awareness of quality management. The management level of printing enterprises is low and the social benefits of book printing and packaging quality are not put in the first place.
Specifically, the publishing administrative department does not pay enough attention to the quality of books and periodicals, book content and editing and proofreading work, and the printing standardization work lags behind, and some existing printing standards lag behind international standards and advanced foreign standards. Some new technologies and processes have no quality standards so far.
As far as publishing houses are concerned, some publishing houses get more profits for their own departments, regardless of the printing quality of books and periodicals, whichever publishing house has the lowest price will go to that publishing house.
There are also editors of some publishing houses, especially Art editor, who are too unconventional and innovative to meet the diversified needs of the market. Because the equipment and technology can't handle it, the result is counterproductive. The quality of paper provided by other publishers is very poor, and so on.
As far as the printing factory is concerned, it is the main person responsible for the low quality of books and periodicals printing. The reason is that outdated equipment is one thing. Other equipment is not backward and can't be done well because the technical quality of operators is not high.
Others use low-priced and inferior materials. In addition, there is a universal problem that cannot be ignored. Since the abolition of the two-level fixed-point book printing enterprise system, the quality of book printing and packaging has not been constrained, which is caused by the relaxation of the management of book printing and packaging quality by printing houses.
