What are the main factors affecting printing quality

Even so, it is unavoidable to have problems with printed matter. Sometimes, inadvertently, we will find vague words on the books, which is caused by improper printing. So, what are the main factors affecting printing quality?

The first reason is the printing equipment. Printing equipment is very important for printing quality. If there is a problem with a part of the equipment, it is easy to cause printing failure. For example: blocking version. Once the blockage occurs, the amount of ink transfer will decrease, which will cause the color of the printed product to change. Therefore, it is necessary to pay attention to the maintenance and protection of the equipment. The second reason is printed materials. Different printing materials will present different printing effects. Good quality printing materials are easy to print, and the writing and patterns are very clear. If you use poor quality printing materials, the poor printing effect is one aspect, and it is also easy to damage. The third reason is the rationality of the plate design. When designing the printing plate, it is necessary to fully consider the influence of the printing plate design on the printing process and post-press processing. For example, the color of the jump zone of the dots is very easy to have levels and levels, so in order to avoid this, it is necessary to take changes in advance. Finally, it has a direct relationship with the printing environment. If the room temperature of the printing workshop of Shenzhen Printing Company changes greatly, the flow state of the ink will also change greatly. Therefore, it is necessary to ensure that the temperature and humidity of the production workshop are controlled within a reasonable range. Of course, in addition to the above factors, when the layout is subjected to irregular wind, the printing speed and drying speed will also change, resulting in changes in the color of the printed matter. Therefore, we know that many factors affect printing quality. Therefore, we must find a professional Shenzhen printing company to print to ensure the printing quality

Commonly used size options for printing different papers in books

book printing

Different paper and different sizes

1. Letterpress paper Letterpress paper is the main paper used for letterpress printing of books and magazines.

The larger the number, the worse the paper quality. Letterpress printing paper is mainly used by letterpress printing machines. The characteristics of this paper are similar to newsprint, but not exactly the same. Because the ratio of pulp and the knocking of pulp are better than that of newsprint, the fiber structure of relief paper is relatively uniform, and the gaps between the fibers are filled with a certain amount of fillers and gums, and they are also bleached, which forms The adaptability of this paper to printing. Slightly different from newsprint, its ink absorption is not as good as newsprint, but it has the characteristics of uniform ink absorption; water resistance and whiteness of paper are better than newsprint. Relief paper has the characteristics of uniform texture, lint-free, slightly elastic, opaque, slightly water-resistant, and certain mechanical strength. Weight: 49 ～ 60) ± 2g / m2.

4 common binding methods for books

Saddle stitching

The position of the spine of a saddle-studded book is opened from the middle, and the spine is connected by wire, sewing thread or other linear items, and the spine is attached together to form a saddle.

1.The student's workbook is bound together by iron wire and has two staples. Is a common way of riding nails.

2.The medical records used in the hospital are stitched together by sewing threads. It is usually called stringing. To put it simply, replace the nails of the riding nails with sewing threads, that is, unfold the book, and use a sewing machine to sew the inner pages together along the middle spine line.

3.Some instructions use glue to glue the spine lines together. For example, two sheets of paper are folded in half, and glue is applied to the outer spine line of one sheet of paper. Of course, in the actual production process, this bonding process is directly completed on the folding machine.

Paperback binding

All the inner pages of the book are stacked together, and the left side is either glued, pressed together with iron wire, or twisted together with sewing threads. It is the book block. The books on the left are generally more than 5mm thick. Apply glue on the spine of the book block, align the creases on the spine of the book case (cover) with the spine of the book block, glue the two together, and cut into a finished product to make a glued book. 1.The textbooks (textbooks) used by students are formed by hot-melt adhesive bonding, which is the most common plastic bag book. The method is very simple: Fold the inner pages together in the order of the page numbers, tidy the left side, and glue the left side together with glue. The cover is wrapped around the book block and is glued together at the spine. Finally, cut into finished products according to the marking line, that is, the bound book we often see. Of course, in the production process, these steps are completed by equipment automation. 2. High-end publications such as galleries and photo exhibitions. The spine of the inner pages is twisted with sewing threads. The twisting of sewing threads here is different from riding staples. It can be seen here as several saddle stitches stacked together, and then twisted together along the spine with sewing threads. It's for book blocks. Then cover the cover with glue and cut the finished product. 3. Most of the reference books, the book case is thick and tough, is for hardcover books. The inside pages of a hardcover book are similar to the glue-locked binding. Just the cover is made of rigid cardboard by gluing, which is used for sealing. The cover and book block are glued together by a part called a ring liner. The specific production process will be explained in detail later.

Iron ring, Rubber ring (YO)

There are two types of ring binding: rubber ring binding and iron ring binding. Its advantages are mainly easy to view and change pages. Product material: iron ring or rubber ring. The cover and back cover usually use transparent or frosted sheets. The commonly used paper for the inner pages is 80 g copy paper or coated paper. The material of the cover is mainly leather paper, copper paper, white cardboard and other materials. Scope of application: Suitable for various office materials, profiles, personal information, business books, training materials, conference materials, etc.

Hardcover book printing

Hardcover printing refers to a delicate method of making books. Hardcover printed books are mainly made by various molding processes on the cover of the book, the back of the book block, and the corner of the book. There are a variety of processing methods and forms. For example, book block processing includes round backs (ridges or ridges), square backs, square corners and rounded corners. , Pressing pattern and so on.
