Single spot color registration system for thermal transfer printing

At present, customers newly purchase gravure printing machines, generally have to purchase machines equipped with a complete set of computerized automatic registration systems. The vast majority of general printing materials are also transparent plastic, white paper, aluminum foil and reflective films. The computer-to-printer control system currently has all kinds of manufacturers on the market, but also has its own characteristics, customers are used according to their own requirements, such as the level of price, ease of operation, after-sales service and so on. Occasionally, our company has found a big area among the customer groups. It is thermal transfer printing. According to the in-depth understanding, the manufacturers of thermal transfer printing, due to the requirements of the production process, use the printing materials for printing on the printing press. Deep-colored paper, the printing presses of these manufacturers are basically completed by manual manual printing. Asked the reason, it is said that there is no one manufacturer that can produce computer-to-printing systems can get support. To think about it, some computer-to-print control systems currently on the market basically adopt the so-called dual-spot photoelectric detection technology. The photoelectric detection elements used in the market cannot accurately distinguish the computer detection marks printed on printed materials and printed materials. There is no way for the control system to work properly. My company encountered one such printing factory. The printing press used was imported equipment. Six-color printing. Whenever printing six-color products, there was one operator's watchman in each printing color base. When the weather was hot, Great taste of shirtless battle. After communicating with the manufacturer's technicians, they very much hope that they will use computers instead of laborious manual operations. However, the manufacturer’s technicians also stated their practical difficulties: the products printed by the manufacturers, the printing roller in the roller house are piled up, and the technicians also know that to use the computer, they must build computers on the printing roller. Tracking color marks, if it takes a lot of price to re-plate. Previously produced printing plate rollers were manually visualized lines for human observation during manual printing; in addition, whether the technicians could detect the currently printed materials on the manufacturer had been known. For the confusion of the manufacturers, our company analyzes each other one by one. The problem of overprinting marks is not a problem. Our company's products have a correction parameter on the operation interface. Our company has experienced technicians who print and we can manually mark on the printing plate roller. Generally, the color registration mark is for each edition. There is a line on the roller 1mm wide and 10mm high, and each adjacent color line is 20mm pitch, because our company's products have the above-mentioned function, can artificially inscribe a line on the roller, and every two color lines The spacing can not be absolute 20mm; our system uses edge detection, there is no requirement on the width of the mark, our system's correction parameters can be positive or negative to two decimal places, so when printing can be put with 20mm gap Increase or decrease over. The problem of detection is not a problem, because our company's products are unique single-spot photoelectric detection, unlike dual-spot photoelectric detection heads, we can special set, plus high reliability and high in their own control circuit. The amplified dedicated circuitry processes the optoelectronic signals to effectively distinguish the material from the color scale signals. After the transformation, the computer color registration control system is in place, because the printed printing plate rollers are all 2 to 3 meters in length, and the upper and lower versions are not easy. A six-color printing press is now operated by only three people, if it is ordinary With the printing, one can, and even more than the original scene of many people bracing themselves into battle, the workers are comfortable, and the manufacturers have also increased efficiency.
