How to solve the influence of photo-curing temperature of screen printing uv machine on printed matter

The temperature of the UV lamp is too high, which causes the high-temperature thermal deformation of the substrate (gold and silver cardboard, laser cardboard, and plastic sheet), resulting in inaccurate overprinting. This is caused by improper selection of the UV machine of the mating screen printing machine. Such UV machines are conventional. Ordinary UV machines use conventional UV lamps. Conventional UV lamps use domestically produced low-purity, light-emitting electrodes, which are filled with low-purity luminescent gas. Only large currents are needed to start the UV lamp, and the production process is relatively simple. The production cost is also lower, the UV lamp produced has low luminous intensity, large light emitting current, high light emitting temperature, and the substrate is heated at a temperature as high as 80-90°C, so that the printed matter is not deformed due to heat deformation, and UV ink and UV can not be dried at a high speed. Varnish, this kind of UV lamp is generally used in slow screen printing production with low overprint requirement, and it is not suitable for high-speed automated silk screen production with high printing requirements.

Solve the problem of UV lamp temperature overprinting must choose advanced low-temperature high-speed UV machine, UV lamp used in low-temperature high-speed UV machine is imported new advanced low-temperature high-intensity UV lamp, low-temperature high-intensity UV lamp is a kind of high-purity light-emitting electrode, filling High-purity luminescent gas with accurate proportion, the low-current, high-intensity, high-pressure mercury lamp produced through high-end technical production process is used in combination with the correspondingly matched power supply, and can emit 365nm low-temperature high-intensity light suitable for UV ink solid-state drying. The intensity is 100% higher than that of the conventional high-temperature and low-intensity UV lamp with the same power, which can make the UV ink and UV varnish dry at high speed, and because the light-emitting current is low, the lamp heat is reduced and the light-emitting temperature is lower than the conventional UV lamp. More than 40%, substrate temperature is only 50 °C, without water cooling can play a low-temperature high-speed solid-state drying effect, Shantou City, South China Machinery Co., Ltd. for automatic high-speed silk screen UV printing process requirements development and production of low-temperature high-speed silk screen UV Machine advanced equipment, the use of imported advanced low-temperature high-intensity UV lamp, equipped with advanced UV lamp cooling system, so that UV light solid temperature control About 50°C at room temperature, the solid-state drying speed is 5000 sheets/hour, which meets the requirements of high-speed printing and multi-color printing. Shantou City, South China Machinery Co., Ltd. production of dual-licensing silk screen printing low-temperature high-speed UV machine products, can be imported and domestic various types of automatic high-speed screen printing machine supporting products from the advent of the Shanghai area has been a number of brand-name automatic screen printing machine factory Supporting, widely used in many large cigarette pack printing plants and color printing plants, has become a well-respected brand in the industry.
