Metal Screen Printing Technology

The scope of metal screen printing is very wide, and the scope of application is also very common. It mainly includes signs, panels, nameplates, decorative plates, supplies, electronic products, molds, printing plates, and printing cylinders. Most of the metal screen printing is decorated with direct printing. There is not much difference in printing techniques, but the surface decoration requirements are of higher quality and must be durable. Metal screen printing is seldom the final product printing, most of which are components of various processing processes such as various containers, covers, building materials, household electrical appliances, furniture, nameplates, and miscellaneous articles. These products are used to enrich people’s lives. For the main purpose. In order to arouse the desire of consumers to buy, increase the value of the sale of goods, as a promotional tool, we must carry out novel framing design and beautiful printing, so for the metal screen printing, we must pay attention to the design of the screen printing to the entire printing Link.

First, metal screen printing design issues to pay attention to

The most important thing in any work is the initial basic work. In addition to considering the economic and practical principles, the design of screen printing as the main process should also pay special attention to the combination of science and art. In ensuring that the nominal accuracy, operation, indication, and display element layout are reasonable, appropriate decorative patterns are added to organically link the characteristics of screen printing with aesthetics and the optical color of the material, and become an important design for screen printing process panels. Conception. In addition, many factors that affect the specific operation of screen printing equipment materials must also be considered in the design. At present, the production of metal screen printing plates has become an important means, because screen printing has incomparable characteristics of other printing, such as its unique performance, can use a variety of inks, ever-changing colors, can accept various shapes of substrates, etc. , to provide users with free choice. The panel is a concentrated expression of the functions of instrumentation products, and it is also an attractive area for products. A high-quality panel can not only reflect the face of the era of science and technology, reflect the modern aesthetic concept, but also show the high-tech value of the product. Therefore, improving the functional design, modeling design, and decoration design of the panel and selecting the appropriate technological means are the goals pursued by the current sign industry. Substrates used in panels are increasingly numerous and there are endless surface treatment technologies. In order to improve the design and process level to create a novel metal screen printing panel, the design should pay attention to the following aspects.

1) Modeling ratio

The molding ratio of nameplate products is closely related to the mechanical structure, overall shape and layout of equipment and products. With the development of the times and the change of aesthetics, the proportion of nameplate moldings is constantly changing. Therefore, the design must not only take into account the product's structural characteristics, but also should consider the current popular aesthetic to determine the proportion of modeling.

2) Emphasize layout and decorative effects

The layout design of each function on the panel and signage should be reasonable, not only to provide the operator with the greatest convenience, but also to require a profound design pattern, beautiful and generous, not only represents the nature of the product but also represents the production unit. In the pattern design, we must pay attention to the following factors. That is, it should have long-term usability and should not be changed frequently; it should be concise and eye-catching, and it can leave a deep impression on people; it has a unique and novel style; it reflects the characteristics and nature of the product. In addition, the decorative effect of signage design is also very important, for example, for those with simple functions, the space area of ​​the panel is properly matched with different shapes of the color, plus the decorative lines will make the monotony of several boring nominal Lively and bright up.

3) Design requirements for lines and color blocks

Because the screen printing is not easy to express the effect of subtle lines, in the two adjacent or at the adjacent place, to leave space or overlap, the width of the line, the size of the handwriting also exceeds the maximum resolution of the plate 0.1mm the above. When designing the printing of color blocks, the outer frame size should be as large as possible to ensure that the size and shape of the inner frame are accurate, so as to ensure that the inner frame is not touched when the screen is closed. When the adjacent color areas do not require space, they must be designed separately, with two rows of lights. These are two differently shaped color areas, and no gap is required in the middle. The intersection of the two color blocks is not easy to print very well. This situation can be compensated by overlapping design methods. The outer frame of the color frame is covered with a frame. This also requires separate design of the two rows. The surrounding area of ​​the patch area should be slightly larger than the drawing requirements. In other words, when the two colors are adjacent to each other, the light area is designed to be printed first, and the dark area after the printing area is pressed. Light color to prevent the middle of the pores.

4) Design of multi-function area panel

Since the panel with more functional areas uses multi-level overprinting or multiple color screen printing, it will make the layout appear cluttered, although the multicolored and slow, it loses its elegance and dignity. According to the principle of darkness in the dots, the neighboring parts in the multi-function zone are printed in the same color in different sizes, different shapes, and different densities. Due to one design, one row of illumination and one printing, the trouble of multiple positioning and multiple printing is reduced, and the efficiency is improved. It can not only play the role of color zoning, but also make the layout of the layout in accordance with the aesthetic style of the times, and subtly blend functional beauty with artistic beauty. The whole machine is properly matched with the panel, comfortable and strong in the times. Can fully demonstrate the high technical value of the product.

5) Selection of fonts and standard symbols

Chinese, Pinyin, English, and numbers are indispensable languages ​​on the signage. Text design not only needs to meet the requirements of the nominal function, but also must have good craftsmanship and aesthetics. The general principle is to meet the characteristics of the screen printing process, after printing to achieve a stable, uniform, easy to read, easy to distinguish the effect. Most of the Chinese characters use Chinese Pinyin letters in Songs, Songs, and Carcasses, whereas English uses mostly body lines, long lines, and flat lines. Numbers are the most common nominal symbols. The ratio of height to width directly affects the recognition effect. The ratio of height to width is generally based on the golden section (0.618). The specific choice is 5:3 to 3:2. Corrosion panel commonly used Song fonts, due to the square shape, the pen front is obvious, horizontal and vertical uneven, the font body is printed on the metal panel below 4.2mm, will appear thin, the title of the print also appears to drift; imitation Roman body, horizontal and vertical thickness uniform, angular Clear, well-designed fonts, small print or headline effects are all very good. When the character body is above 4.8mm, the bold characters are more often used. The characters are dignified and generous. The strokes are thick, and they are printed on the panel to be sturdy and eye-catching. Larger titles or spaces are larger. It is possible to use a square typeface or a variant type body. It appears open, discouraged and has a strong sense of calligraphy. The standard signs are generally used in signage, such as nominal on electronic instrumentation, commonly used English letters or various symbols, for the sake of accuracy, we try to use Huitong standard symbols directly maps. The commonly used Chinese characters do not use handwriting. Instead, the words on the letter board are put into a positive film as required, and they are pasted on the drawings, and then turned into Yin and Yang negatives to ensure the consistency of the entire font.

6) Carefully analyze the drawings

Under the premise of respecting the wishes of users, we will take the initiative to negotiate artistic re-creation with users, apply mature techniques and unified images to different products, and establish our own style. According to the design sketch provided by the design, the positive drawing, engraving, or mapping is performed. Since the application of the microcomputer has been used to design the system, the microcomputer design is used. The light drawing version is a relatively advanced technology, and the size of the design is also compared. accurate. If there is no advanced equipment, drawing, mapping, engraving, etc. can also be used for less demanding products.

7) Pay attention to the weak links in overprint panels

The level of craftsmanship is the technical basis for guaranteeing and representing the level of design. It is also the creation of the beauty of the product's texture, thereby enhancing the protection of the formal beauty. Therefore, screen printing should also prevent rough fabrication and damage the appearance of the image. It is often found that different manufacturers print different products on the same film. There are technical differences, there are also differences in color matching, material selection, and more is the difference in the quality of the process. (to be continued)
