Increase packaging competitiveness

People want clothing, things to be packed, and packaging and decoration are more and more valued by people. It can not only play an active role in protecting goods and beautifying goods, but also promote the continuous development of goods. The packaging and decoration are very important in the packaging and decoration. For packaging printing to achieve better results, it is necessary to seriously solve the three major relationships of prepress processing, printing process and postpress processing.
A successful packaging and decorating print has brought together the collective wisdom and hard work of designing, printing, and post-press processing workers. Therefore, in order for a piece of packaging and decorating printed matter to achieve the desired effect, it is necessary to have an overall concept of overall consideration from the outset, and it is by no means only concerned with a certain process but without considering the feasibility of other processes. Colored packaging is now used more and more, as a precondition for color reproduction, which is based on manuscripts. Platemaking is a series of interconnected operational processes for the purpose of means and printing. Therefore, in order to enable Luneng to achieve the best reproduction effect within the allowable range, it is necessary to take the customer's requirements as the goal and control each process step separately so as to formulate a reasonable process route and operation instructions. . At present, the packaging printing is still based on offset printing. We must solve the relationship between prepress processing, printing process and post-press processing. According to my experience in packaging and printing work, I will talk about some experiences.
Design is the primary link of packaging and printing
The design of packaging and decorating printed matter is the basis of plate making, printing and postpress processing. The design draft of a packaging and decorating printed matter is often a combination of patterns, colors and words. The overall design of this product not only needs to see the characteristics of the goods and artistic beauty, but also takes into account the actual effects of plate-making and printing and the completion of post-press processing. The design has to face two aspects: On the one hand, the design of the product needs the customer's needs, to meet the customer's requirements; on the other hand, we must also meet the actual situation of our plate printing, post-press processing. Some of our designers think one-sidedly that the more color the package is printed with, the better, and the process materials are also quite particular. In the draft, there are often four or six colors, and hot stamping, embossing, embossing, stamping, etc. are used for the 18 martial arts. This kind of design did not consider the economy or the technical feasibility of plate making, printing, and post-press processing, resulting in some products that, although the designers thought well in advance, the actual results were poor. So design is a primary link. Designers should make full use of the principle of offset printing and the color reproduction of three primary colors, so as to reasonably use color and reasonably use process materials to produce colorful decorative prints. Of course, we must give designers the opportunity to go out and study regularly, so that they can broaden their horizons, adapt to the domestic and international trends, and constantly improve their own business level and design better and more beautiful products.
Platemaking is the bridge of design and printing
Platemaking is the bridge between design and printing, and it is the middle part of the entire production process, playing a role in the connection. Platemaking not only correctly reflects the requirements of the manuscript design, but also corrects those parts that do not meet the printing process requirements so that the printing can be reliably carried out. For example, some plants have different types of offset presses, domestic ones and imported ones; some products have high overlay precision, and some products have high requirements for network expansion, so it is necessary to target various models in the process of plate making. The technical performance uses different platemaking process measures. Monochromatic machines must consider the accuracy of overprinting, and multicolor machines must consider overprinting and the resulting sticky and dirty problems. In particular, multicolor machines are more common nowadays. In consideration of the effect of actual printing, a non-color structure platemaking method can be used. For example, when a monochrome machine prints a four-color printing plate, C=95%, M=88%, Y=88%, and BK=75%.
When using a multi-color machine, use the background color to reduce the grey component of the three-color version of C, M, and Y by 20%. The amount of tricolor ink after removal was 306%.
The original traditional four-color ink ink has a superposition of 346%. With the non-color structure technology, the 20% tricolor version of the gray component ink has a superposition of 306%. Compared with the above, the total ink amount can be reduced by 40 percent. The thickness of the ink on the paper is reduced. In this way, in the multi-color printing machine, stickiness can be avoided, which is beneficial to the drying of the ink. At the same time, it is also conducive to the stability of the color and facilitates the control of the gray balance.
In the process of plate making, we must pay attention to the quality inspection of the color-transparent originals, and the poor quality of manuscripts must not be used. In the whole process of plate making, it is necessary to strictly implement the technical measures, and to use the control bar to control the quality of each color version. Do data, standardization, and standardization. It is necessary to create better learning and practical opportunities for the plate-making process operators so that they can truly grasp the skills and skills of each process.
Printing reflects the effect of design plate making
After the design plate is printed. Printing is the first line of production that reflects the effects of designing plates. We must treat printing with care. Before the printing, the technical and technical department shall propose corresponding technological measures according to the conditions of the enterprise. Some export or demanding packaging and printing products should be taken seriously. For operators, we must emphasize the normative operation. In particular, attention should be paid to inspection of color, lining pressure, implementation of Sanping two small, four-phase operation method and so on. We must strictly abide by the process discipline and operate according to the quality standards of printed products to ensure the quality of the printed matter, especially the range of good control of color difference, and strictly control the E value of color, so that packaging and decorating printing can achieve a rich network of dots, a strong sense of three-dimensional, and bright ink Effect.
Postpress is the final link
Post-press processing is the final link of packaging and decoration printing Lu, which can increase the added value of printed products. Many packaging and decoration products use some special processing methods, such as: anodized aluminum hot stamping, glazing film, embossing die-cutting die-cutting and so on. These processes are called printing in the packaging and decoration printing factory. After processing.
Post-press processing is the further modification and embellishment of printing and printing after printing, and it is the application of special technology in packaging and printing. Therefore, we cannot wait to look at it. It is the final link. If it is handled badly, it will work harder and cause a lot of economic losses. Therefore, we must attach great importance to it.
There are many processes in post-press processing that are traditional processes, but there are now few successors. For example, the current production of engravings and embossed engravings is such a situation. We must pay attention to the cultivation of these craftsmanship so that these traditional craftsmanship will continue to flourish. It is urgent to do a good job in this area. It is necessary to make the post-press processing healthily develop and better serve the packaging and decoration printing.
In summary, to achieve good results in packaging and decorating printed matter, it is necessary to handle the relationship between prepress, printing, and postpress processing. In the specific operation, it is necessary to coordinate the operations of each process, and emphasize the overall process of the entire process. Management, to do a deduction, from the prepress, printing to postpress processing must be the standard process design data as operating guidelines, to achieve data, standardization, standardization, with first-class product quality to make users satisfied, This will enhance the competitiveness of the product in the market.
