The production of anti-counterfeit labels is closely related to combined printing. Whether it is offline combined printing or online combined printing, gravure, offset, flexo, silk screen, embossing, variable information, holographic hot stamping, laser aluminum foil and other technologies have played important effect. The mutual penetration of a variety of printing equipment and processes makes printed graphics and text more unpredictable and colorful. And the label products using combination printing technology also set up a lot of obstacles for counterfeiters, to achieve the purpose of anti-counterfeiting.
Combined printing and anti-counterfeiting technology
Anti-counterfeiting technology is adopted to achieve the purpose of anti-counterfeiting. It can accurately identify the authenticity within a certain range and is not easy to be copied and copied. It has technical barriers, scale thresholds, equipment thresholds, craft thresholds and other barriers, which are difficult to be copied and copied. Purely from the perspective of printing technology, anti-counterfeiting technology mainly includes engraving and plate making, computer-designed pattern, gravure printing, rainbow printing, pattern docking, double-sided printing technology, multi-color wiring printing, multi-color overlay printing, micro printing, materials Texture, latent image, invisible image and image interference printing, etc. With the in-depth development of anti-counterfeiting technology, some new forms of anti-counterfeiting technology, such as two-dimensional code, RFID and other anti-counterfeiting technologies have also been produced, which effectively meets the growing market demand.
Generally speaking, it is not easy to print high-quality prints with a single printing method, and the anti-counterfeiting effect is limited. In order to achieve a suitable anti-counterfeiting effect, a variety of anti-counterfeiting technologies are often applied in the actual production process. Therefore, the combination of multiple printing processes and anti-counterfeiting means can produce high-end label prints and label prints with higher and more complex process requirements, so as to achieve the purpose of anti-counterfeiting. It can be seen that the birth of combination printing is an inevitable product of the development of anti-counterfeiting technology to a certain stage.
Process advantages of combined printing
In combination printing, it is often applied to multiple printing technologies and processes. Therefore, combination printing also combines the advantages of multiple printing technologies and processes. In general, combination printing often combines the advantages of gravure printing, offset printing, flexographic printing, and screen printing.
The advantages of various printing methods are as follows. Gravure printing has the advantages of high production efficiency, good hue consistency, and good adaptability of printing materials. It has excellent performance in field, spot color, and gold (silver) ink printing, and can meet the strict requirements of packaging printing quality. For offset printing, there is a set of standardized and data-based methods for the reproduction of printed products with rich gradation. Flexo printing, due to short ink path and no color difference in printing, has unparalleled advantages for solid color printing. In particular, with the rapid development of the flexographic supply chain such as plate materials, plate-making equipment, printing machines, etc., the quality of flexographic printing has made rapid progress, and the reproducibility of the tone level is good, which can meet the higher printing requirements. The importance of printing is getting higher and higher. The screen printing can produce a thick ink layer, creating a variety of effects such as bumps, frosting, refracting, ice flowers, wrinkles, etc., thus greatly improving the visual effect of the printed matter.
Anti-counterfeiting effect of combined printing
Generally, high-end label prints are designed with large-area color blocks, multi-color sequential continuous adjustment screens, and complicated lines and patterns, etc., which brings certain difficulty to a single printing method, and combined printing solves this well. problem. It can give full play to the advantages of various printing methods and avoid disadvantages. Such as the use of flexo printing on a large area, offset printing of four-color continuous blending of complex lines, gravure printing of metallic colors, silk screen printing of embossing and scratching layers, so that the advantages and disadvantages are obvious.
In short, the more complex the printing process and the more difficult the printed label, the better the anti-counterfeiting effect. The combination of gravure printing, offset printing, flexo printing, silk screen printing, cold stamping and even hot stamping is an anti-counterfeiting combination in itself. The realized label products combine these processes with some unique designs, plus variable information and QR codes At the same time, the combination of ink anti-counterfeiting technology and holographic anti-counterfeiting technology has realized the uniqueness of the product and can be mass-produced.
Application of combined printing in labels
Combination printing is widely used in label printing in China. In order to ensure the safety performance of the label and prevent the label from being illegally copied, in actual production, offset printing, gravure printing, embossing printing, silk printing, holographic hot stamping and other methods and variable information numbers are generally used to ensure the safety of the label. Such as China Instant Sports Lottery, the lottery adopts a variety of printing methods such as front and back printing, anti-transmission printing, miniature text, variable-line data printing, peel-off varnish printing, scratch-off ink printing, and color patterns and glazing. The wiring process is complex and plays a very good anti-counterfeiting role. Another example is daily chemical and bath product label printing, which combines embossing, flexo printing, silk screen, ink anti-counterfeiting, texture anti-counterfeiting and QR code anti-counterfeiting technologies together, which increases production efficiency and improves product functions and anti-counterfeiting effects . Alcohol anti-counterfeiting labels use an offline process, which combines printing anti-counterfeiting technologies such as embossing, flexo printing, silk screen, variable information, hot stamping, plate pattern and miniature to make the product have a very good anti-counterfeiting effect!
In short, combined printing not only brings out the best features of several printing methods, but also complements each other to improve the grade and quality of the printed matter. Combined with various anti-counterfeiting technologies, it integrates various anti-counterfeiting technologies with beautifully printed labels and printed products. Protected the corporate brand, protected the market, and protected the legitimate rights and interests of consumers! The pioneers who adopt the combined printing process will also get a good profit return.
Sieving machine, as part of production line, is necessary in industry production, food processing, chemical powder grading. Currently we have round sieve, square sieve, centrifugal sieve, high precision sieve and test using sieve.
Mainly working principle is to sieve material (powder, granule) to different sizes or remove impurities by gravity. Also different type of screen cloth cleaning device were used to clean different materials, like bouncing ball cleaning system, ultrasonic systems, air vibrationg systems, brush clean system.
This type machine is pretty simple in structure and stable working. Durable quality make this machine can keep long time for 24hours working.
With a wide range, good quality, reasonable prices and stylish designs, our products are extensively used in mining, pharmacy, food, chemical, metal powder and other industries.
