Analysis of design points of Adhesive Name Stickers combination printing process

So far, the printing quality control has experienced a change from the concept of "quality is tested" to "quality is manufactured", and then to "quality is designed", which fully reflects the reasonable process design to obtain excellent printing quality. importance. Because of this, some of the larger Adhesive Name Stickers printing companies have delegated this work to a separate team or individual.

In recent years, some high-end Adhesive Name Stickerss are completed by combination printing. Combination printing is a collection of various printing processes such as flexo printing, gravure printing, letterpress printing, screen printing, offset printing, etc. Therefore, the design of the Adhesive Name Stickers combination printing process involves many matters. If it is not considered comprehensively, it will affect the final printing quality. . In order to do a good job in the process design of Adhesive Name Stickers combination printing, the author believes that we must first understand several necessary factors of printing: printing materials, inks, printing plates, printing machines, and then design a reasonable process according to the matching of these factors. Let's talk about the design points of the Adhesive Name Stickers combination printing process according to these factors.

The choice of printing materials

The printing material is one of the important raw materials for Adhesive Name Stickers printing, and the quality of its characteristics directly affects the quality of the printed product. When Adhesive Name Stickers printing companies choose the printing materials for Adhesive Name Stickers combination printing, they must choose the best printing materials according to the specific requirements of customers, combined with the purpose of the Adhesive Name Stickers, the use environment, and the production capacity of the printing equipment, while controlling the cost.

1. Select the printing material according to the characteristics of the object to be pasted

If the Adhesive Name Stickers is pasted on a spherical object, do not choose a material with high stiffness, but a soft material, such as paper or film material. There is such a case: when a company prints a batch of drug Adhesive Name Stickerss, it chooses transparent BOPP film because of its aesthetics. However, due to the high stiffness of BOPP film and poor followability, the Adhesive Name Stickers edge "starts" appear soon after Adhesive Name Stickersing. Warped" phenomenon, and finally switched to coated paper to print the Adhesive Name Stickers, the problem was solved. Of course, in the case where a transparent self-adhesive material with high stiffness has been selected, the perfect adhesion of the Adhesive Name Stickers on the spherical object can also be achieved by changing the adhesive used for the material.

2. Select printing materials according to the purpose of the Adhesive Name Stickers

For example, since the Adhesive Name Stickerss attached to the hose are often squeezed, PE materials that can withstand a certain pressure should be used; the Adhesive Name Stickerss of cleaning products should preferably be made of film-based waterproof materials, or the purpose of waterproofing is achieved by laminating paper materials.

3. Consider whether the selected substrate can be printed on the combined printing equipment

Combination printing equipment has strict requirements on the printing materials. In addition to the requirements on the thickness and width of the printing materials, due to the influence of the tension between the units, there are also high requirements on the stretchability of the printing materials.

4. Cost control

Under the premise of meeting the requirements of use, materials with lower cost should be selected to reduce unnecessary waste.

In short, the choice of printing materials must meet the requirements of customers, and Adhesive Name Stickers printing companies should provide customers with the best possible choice of printing materials for their reference.

Applicability of ink

There are many types of Adhesive Name Stickers printing inks, and several factors such as the use of the Adhesive Name Stickers, the type of printing material, the printing process and the printing conditions should be considered when choosing.

First of all, the purpose of the Adhesive Name Stickers is the most important factor in determining the ink used. For example, Adhesive Name Stickerss used outdoors must withstand the test of wind, sun, and rain. When choosing ink, attention should be paid to its light resistance, water resistance, high temperature resistance, etc.; Adhesive Name Stickerss used for cleaning products are susceptible to solution pollution and corrosion. Therefore, it is required to The ink must have good acid and alkali resistance and grease resistance.

Secondly, the printing material is also one of the important factors affecting the selection of ink. Different inks have different transfer properties, and the rendering effects on different substrates are also different. The ink that matches the substrate should be selected.

Again, the ink should also be matched with the printing method. Generally speaking, the inks used in letterpress printing, gravure printing, offset printing, etc. are different, and there may be incompatibility between different inks, resulting in problems in overprinting rate and adhesion. In addition, inks are sometimes incompatible with other post-press finishing processes, so before combined printing, it is necessary to conduct compatibility testing of inks and obtain necessary technical support from ink and other consumable suppliers.

Production of printing plates

Combination printing integrates a variety of printing processes, so the production of printing plates is also an important task. Of course, making printing plates according to the customer's design requirements is the principle that should be adhered to.

In order to ensure that the printing color effect meets the requirements of the customer's design, during the pre-press plate making, the customer's original should be first made art, and on the basis of a comprehensive evaluation of the accuracy of the combined printing equipment, appropriate trapping processing and dot increase compensation should be made for the printed graphics and text. . When separating colors, in addition to arranging the color sequence, special attention should be paid to the color shading. For example, for Adhesive Name Stickerss pasted on black objects, a white background should be placed under the 4-color pattern to reduce the impact of the stickers on the Adhesive Name Stickers. Then, select the appropriate plate material according to the printing process, such as paying attention to the hardness of the resin plate, the engraving method of the gravure, etc.

The printing capacity of the equipment

Nowadays, many manufacturers can provide printing equipment with a combination of offset printing, letterpress printing, screen printing, etc., and achieve the best printing effect through various printing methods. However, in order to make good use of the combined printing process, Adhesive Name Stickers printing enterprises also need to pay attention to the alignment method of multiple processing process designs, and regularly monitor the printing curve status of the equipment to ensure the printing capacity of the equipment, so as to better reproduce the design effect of the original.

In a word, Adhesive Name Stickers combination printing combines a variety of printing methods, with complex process and strong technicality. It requires Adhesive Name Stickers printing companies to meet the final needs of customers as the goal, select appropriate printing materials, inks and plates according to the printing capacity of the printing equipment, and Do a good job in the internal control of various parameters, so that subsequent production can be carried out smoothly.
