In the process of book printing quality of lamination, the easiest to appear the quality problem of the lamination of products is glued rickety, easy to fall off; it will directly affect the sequence effect of product use effect and after life. To solve this problem, we need to combine considered printing ink, printing process, lamination process and so on.
About printing ink
When lamination, the white ink pigment particles in the surface of ink can hinder the adhesives and influence the adhesives on the surface of the printing ink The aluminum hydroxide in the oil is easy to form the isolation layer, blocking the interaction between the adhesives and the ink layer, causing the foaming or adhesion to be untrue; The light slurry has good effect on the coating effect, and its composition is similar to the adhesive properties. Therefore, when adding ink diluent, we should combine the laminate effect of the product for comprehensive consideration.
In addition, the particle degree of ink also affects the effect of lamination. The granule passes through big, can affect the lamination effect of the film and the printing surface, easy to appear bubbling, then the cement is not real. Especially gold and silver ink, due to the metallic pigment particles in dry ink to separate, hinder the combination of ink layer and adhesives, so using gold and silver ink printing product is not suitable for lamination.
About printing process
The book printing before laminated need to finishing by printing. After drying of the surface layer of ink performance will influence effect of lamination, and on the premise of appropriate use of ink, printing format, ink layer thickness, drying effect factors can cause laminating adhesive. If the printing format is too large (or using field printing), makes the paper surface to reduce the contact area and adhesives, intensifying declining print surface bonding effect with adhesives, the effect of the quality of the product and service life.
If the printing ink layer is too thick, the resistance to adhesive can be aggravated, which will directly cause the delamination, which can not be cemented. Comparing all kinds of printing ink layer characteristics, offset printing quality ink layer thickness, the lowest for 1 ~ 2 microns, so offset printing will better, laminating and attention should be paid to control color printing overprint effect and print the ink layer thickness.
Similarly, the undrying ink will cause lamination to expand and elongate, causing the laminating products to bubble, the film glued rickety. The key to solve this problem is to ensure that the ink completely dry before laminating, can adopt the way of auxiliary drying speed up production, but try to minimize the use of ink adjuvant.
Lamination process
1. The drying effect of adhesive
Adhesive to dry ink drying effect and the print surface situation is similar to impact on the quality of laminating machine, if the solvent is not dry completely, makes the film stretching, produce bubbles, then cause glued rickety.
2. The bonding effect of adhesive
The binding effect of adhesive is mainly considered in two aspects. Is the performance of adhesive laminating, requires both adhesive evenly on the surface of lamination, the effect is good, and according to the printing quality of the surface features and structure control adhesives thickness: the thickness too thin, can reduce the adhesion strength of the adhesive; Thick thickness can affect the drying rate. The second is the compound temperature, which can affect the molecular energy and molecular force of the adhesive. When the molecular force is over an hour, the adhesive force of the coated product is too small. In addition, composite temperature is too high, and can cause damage to membrane structure, general requirements composite temperature control in 70 ~ 90 ℃.
3. Effect of covering pressure
The effect of laminating pressure is influenced by two factors: compound pressure and membrane speed. Compound pressure can promote the penetration and diffusion of adhesive, and its size should be considered in combination with coated material and other process. Membrane speed is also a multi-impact parameter. Its size can affect the coating thickness and drying speed of adhesive, and it needs to be adjusted in combination with other factors.

A good brochure printing attractive not only its content, more important is combined with a words play an important role in the pictures. It is the customer communication, let the customer have a intuitive understanding of the Bridges, like a poster, a promotional stickers, sell yourself is the first time, but how can I get the picture of the brochure very attract people?
Good brochure printing design must have some sort of enterprise propaganda purposes, and timeliness is very long, very impressive, this image has a high requirement for brochure. First, it must have a noticeable effect: effective use of graphic visual effect to attract the reader's attention. This instant violent "effect", only the graphics can be achieved. See reading effect: the good graphic design can accurately convey the theme, make readers easier to understand and accept it conveys information. Figure shape performance varied. The traditional face can produce all kinds of painting, photography, graphics, images with different architectural styles. Especially in recent years, the use of computer aided design, greatly expand the graphic creation and performance between empty. However, no matter use what means to show, graphic design can be summarized as two representational and abstract category.
Has the beautiful image, but also is far from enough, these images are only some specific image, line color, but if just clutter piled up, also have no effect. Representational graphic to show the concrete forms of the objective object, at the same time can also show some artistic conception. It in visual image to convey the lingering truly form beauty, texture, color and so on, has the sense of reality, easy to arouse people's interest and desire, from the vision from the psychological to the trust of the people. Especially some products with beautiful appearance, use real images through the exquisite design and production to bring pleasant feeling. Because it is these characteristics of representational graphic in the design of a brochure is still dominant.
So, in terms of pictorial design, image always easier than words to let readers to accept the first time, is also the first impression of customers in your business, so in the production and must be limited to consider when selecting a pictorial design images, and design the best pictures, sort out the perfect picture brochure design.

Offset printing is using automatic assembly line operations, Computer automatic control, printing tower roller rolling printing, transmission with automatic transmission. Offset printing is mainly white and four main basic colors (Cyan, Magenta, Yellow, Key Plate) of different proportions to deploy a variety of printing colors. And the depth of the various colors depends on printing plate time, printing pressure and printing temperature.
In all large printing companies, Offset printing machine indispensability. This is a proof of strength for the printing company. So, what are the advantages of Offset Printing?
1. Compared with screen printing, Offset printing is high efficiency, high quality, low cost.
1). high efficiency. Offset printing is using automatic flow of operations, the machine automatically color, computer automatic monitoring, Printing fast. 15,000 per hour can be printed. At the same time the speed of printing is also affected by the thickness of the paper, the thinner of the paper, the faster printing, the thicker of the paper, the slower printing.
2). High quality. Offset printing is using computer fine-tuning, accurate color and high position accuracy.
3). Low cost. Offset printing is with roller printing, less oil.
2, can be printed out of the gradient and the color is very realistic products, each color in the link where the transition can be gradual transition docking, the general screen printing cannot be achieved this effect;
3, Offset printing machine can print complex patterns, gradient effect and image effects;
4, Offset printing can print a variety of colorful colors and can contain a lot of text inside, to overcome the water transfer due to difficult positioning and cannot print the shortcomings of multiple words;
There are certainly shortcomings for offset printing. The shortcomings of the offset printing are the cost higher than the screen printing, machinery and equipment need large investment and not suitable for those irregular shape and rugged, 3D surface asymmetric product printing, not like water transfer do not subject to product shape restrictions.
