How to define and distinguish the quality of album printing?
A good-looking and useful album requires a lot of effort. A good album is not to be ignored in terms of design and paper. Album printing is mainly based on photo display. Album printing plays a role in communication. It introduces people to the advantages and services of the company and business. Having a very good-looking album can make a better profit for the business. So making a good-looking album requires a lot of attention, such as album design.
The first thing to do is to determine how it looks. The appearance of a good-looking album is also important. The necessary layout should be clean and free of obvious dirt; then it is its color tone, which should be basically the same; then the text of the album, which should be complete, clear, and properly positioned; finally, the size requirement is the size error of the boutique should be less than 0.5mm, followed by its color, which should be in line with the original design, real, natural and colorful. Indicators should include two aspects: First, the field density tolerance of different prints of the same batch of products; second, the color is consistent with the printed samples. Each tone should be clear, and the layers should be clear.
Then there is overprinting; the outline and position of the multi-color image should be correctly aligned. Finally, as the basic unit of printing, the dot should be clear, the angle should be correct, and there should be no ghosting. 50% of the expanded value of the dot is 10%-20% for small samples; 10%-25% for general book prints.
Know how to define the quality of album printing, then we should identify the quality of album printing good or bad? There are many ways to identify; today, we will introduce two. One is the hand touch inspection, through the sense of touch of the sense organs to reflect. Hand touch inspection can be found in the paper thickness of different problems; experienced people can also grasp the degree of paper thickness by hand touch. Hand touch inspection can also determine whether the paper is entrapped inside the grass tendons, fiber bundles, fine sand particles so as to find hidden paper disease. Some small pulp bumps and white sand particles on the paper, because the same color as the paper, the naked eye is not easy to find, but can be felt with the hand.
The other is oblique inspection. The appearance of some paper defects, such as oil or dark lines, traces of tweed, paper surface shadow traces, etc., with horizontal inspection methods are not easy to find, only through oblique inspection to see. Oblique inspection is to use both hands to lift or put down one side of the paper, from a different angle to see the paper, the appearance of paper quality found to be defective or inadequate.
What are the causes of booklet printing quality problems?
There are many factors that cause booklet printing quality problems, and obsolete equipment is one of the—low skill levels of workers and poor quality of raw materials. The main cause is the publishing sector, their general awareness of quality management is weak. The low level of management of printing enterprises, booklet printing quality is not put in the first place.
Specifically, the publishing sector does not pay attention to book printing, book content and quality are not uniform, printing standardization is lagging behind, and some current printing standards lag behind international standards and advanced foreign standards. Some new technologies and processes do not have quality standards.
In the case of book printers, it is often the main responsible for the low quality of book printing. The reason is that outdated equipment is one aspect.
There is also equipment that is not backward, but the technical quality of operators is not high, and some use low-cost poor quality materials, etc.
For publishers, some publishers, in order to obtain more profits, regardless of the quality of printing books and journals, which print books and journals in printers, who have a low price, who will print. Some publishers' editors, especially art editors, are too innovative and do not adapt to the needs of market diversification. Because the equipment and processes cannot be processed, the results are counterproductive. There are many factors, such as the poor quality of paper provided by other publishers.
Today, the book printing industry in China is growing rapidly, mainly due to the increase in customer needs and requirements. Sprinting is constantly seeking new ideas and striving to find resonance in design, printing, and finishing to achieve win-win results.
