Rotary screen printing is a type of rotary screen printing. Nowadays, consumers are increasingly demanding product packaging. In response to this market demand, packaging designers and packaging printing companies are actively seeking suitable solutions. Rotary screen printing can be regarded as an effective Solution.
The combination rotary screen printer has quickly exceeded its original pressure sensitive label printing application. Rotary screen printing unit printing UV varnish can get very high gloss or relief effect; rotary screen printing metal ink can also replace the traditional hot stamping process, and the cost is lower, will not cause pollution to the environment; for high For density-required printing, such as electronic label (RF1D) printing and magnetic printing, rotary screen printing is an ideal choice; for printing using fluorescent inks, sublimation inks, and other specialty inks, rotary screen printing is also very suitable select. In order to obtain the unique printing effects that screen printing can provide, narrow-web printing companies began to use screen printing units, such as printing white or other colors on the film and foil substrates as the base color by screen printing. Then use offset printing, flexo printing or gravure printing to overprint the color patterns and logos, which greatly improves the grade and added value of the product, and can obtain a generous profit return.
There are relatively many products developed by using the rotary screen technology abroad, and they are also widely used. Whether for textiles, walls, packaging printing or security printing, rotary screen printing can bring exciting innovations to people Results.
1. Smart label RFID
An important use of rotary screen printing machines is to provide safety features for products. These features help protect brands and combat counterfeit and shoddy products. Continuous flash strips and scratch strips printed with seamless screens are our common safety features. RFID antenna printing requirements are very precise. Due to the printed tracks and the equal spacing between the tracks, the precise appearance size directly determines whether the antenna can work correctly according to the requirements. Rotary screen printing is a very effective RFID antenna printing method, and is the only printing method that can directly print thick conductive ink directly on the surface of the material, and the thickness of the ink can be from a few microns to 300 microns. The uneven force of the knife caused by the knife on the flat screen causes the uneven thickness of the ink layer, and the conduction is more stable. It can realize the continuous printing of printed patterns, and it can get precise appearance patterns with one connection, fast and accurate.
RFID tags can provide anti-counterfeiting functions, and can effectively track products, boxes and pallets through the supply chain, while reducing costs and providing users with better stock forecasting methods.
The production of high-frequency and ultra-high-frequency RFID tag antennas has now become the focus of attention of printing plants worldwide. The configuration of the production line is a matter of different people, because the antenna has three different printing processes:
A. Etching high-frequency antenna-print a UV anti-etching protective layer on the positive image made of copper or aluminum plate.
B. Electroplating (high frequency antenna)-printing catalyst before copper plating.
C. Direct printing of silver ink (UHF antenna)-printing silver ink at the fastest speed.
When designing the drying and curing system, we must also consider other special factors-this matter also varies from person to person.
In the printing process of the RFID antenna, you must learn to balance the interests of all parties, because the track and coverage area of ​​the conductive ink in the antenna must be accurately measured, otherwise the label will not work properly.
2. Industrial applications
Solar energy, as a renewable new energy source, has attracted more and more attention. Photovoltaic power generation is a way of using solar energy, and has been widely valued for its energy-saving and environmental protection effects. In recent years, photovoltaic power generation has developed rapidly, photovoltaic technology has continued to progress, and the cost of photovoltaic power generation has continued to decrease. Various countries have issued various policy supports, making photovoltaic power generation the fastest-growing industry in recent years. It has been developed to the third generation of solar panels abroad, which is characterized by the direct printing of photovoltaic materials on a roll of flexible plastic film by Rotamesh rotary screen, which is easy to curl, carry, and collect. It is the first and second generation of solar panels. breakthrough.
3. Braille
In many European countries, especially the UK, France and Spain, brand owners and retailers are striving to spread product information to the visually impaired. The rotary screen printing machine can effectively print Braille, which is also one of the best ways to print Braille. It is often used by people to print brand names, product information, expiration dates and product ingredients. In 2006, the European Union required that all drug packages must have the product name and drug concentration printed in Braille. With the progress of society, the introduction of relevant domestic regulations will create a lot of market space.

People often use a colorless varnish to print dots on the original image, but the premise of doing so is to keep the original image clearly visible and intact. This is the case for the CorteReal label printed by Argraf Autoadhesivos. In 2006, the European Union required that all drug packages must have the product name and drug concentration printed in Braille.
One of the most innovative features of rotary screen printing machines is the printing of thermochromic inks. These inks are very sensitive to temperature changes and can be used to print time-temperature indicator labels. Irreversible ink will not return to its original color after changing color. If the products that are easily deteriorated are stored for too long or the storage temperature is too high, then this ink will change color. The reversible ink can change back to the original color, so it is more suitable for displaying the best drinking time of wine. The Bebicash wine label printed by GraficasVarias shows a series of blue shades, so that consumers can see that the best time to drink this wine is between 8 and 16 degrees Celsius.
