First, from CTP NGP, a time to cross CTP technology (Computer - appeared in plate) to - in the 1980s, the period was direct plate-making technology research early So in the meantime, whether technology or plate-making aspect of quality, are not very mature; To the 1990s, equipment manufacturer and printing factory closely, accelerate the pace of this technology research and development, and during this period reached industrial application levels; In 1997 and 1998, directly platemaking machines price during drastically, and direct plate-making plate began to mature and development, so many CTP printing began to accept and use In recent years, due to the CTP technology continuous improvement and innovation, make this technology has been widely promotion and But, equipment, materials, technology high cost should be further improved and the process of making pollution problems appeared out The Chinese academy of sciences institute developed "chemical nanomaterials green plate-making technology" (NGP) not only fully meet the current mainstream printing business in accuracy, speed, quality requirements, and solved the equipment, supplies cost is high and environmental pollution, waste of resources, completed plate-making technology from photosensitive era to the photosensitive era Second, NGP definition Nano material Green plate-making technology (NGP) Green Plate, Nano, slam the door now gets by photographic materials photographic chemistry coating and the technical ideas, using imaging in Nano structure of the Plate on the principle of direct print imaging, as digital camera film photography, instead of in the process of making thoroughly solved the problem such as pollution and waste of Three, NGP technological advantages The first generation of laser printing technology -- tradition Traditional laser printing process tedious, time-consuming, need to avoid light operation, and there are two steps photographic and chemical flush steps, to ecological environment bring heavy burden; The second generation - CTP technology CTP plate-making technology process simplification, a high degree of automation, ellipsis photographic films steps, but CTP technology is still based on chemical photographic imaging principle, inevitably consumes developer and chemical flush produce pollution; New generation - nanometer material green plate-making technology NGP technology through long-term development and application, show a lot of disadvantages, so relevant researchers are looking for a more accurate, efficient and environmentally friendly CTP new The Chinese academy of sciences institute of nanomaterials chemical r&d green plate-making technology slam the door now through photosensitive material beforehand coating and photographic chemistry imaging technology thinking, using nanometer materials directly to the principle of imaging in the process of making thoroughly solved the problem such as pollution and waste of Four, nanometer material green plate-making technology equipment Now commonly used CTP equipment have thermal plate-making equipment and purple laser plate-making equipment two kinds, among them: thermal plate-making equipment mainly using thermal imaging technology to achieve plate-making But there are many CTP thermistor deficiency, such as laser power demand is higher, the production cost partial higher; And purple laser CTP equipment although by high precision, fast, but for the life, the production cost misbalanced and environmental pollution problems such as their Nano material green plate-making technology equipment NGP platemaking machines used high integration micro piezoelectric ink-jet unit as physical imaging foundation, you can ensure that don't lose points, has outlets by printing process, reducing the impact of the changes that small, The whole plate-making process only needs to two step can, do not produce any pollution and waste of resources, Five, NGP plate-making related consumables Currently on the market CTP plate main types: silver type, light polymerization type, thermal type (thermal imaging type) Nanomaterials inkjet imaging equipment supporting the related consumables contains nano plate and nano ink, to match the use of Nano plate Nano plate is to solve the super close water plate and nano ink invasive core technology: nano plate surface by certain size, structure composition, the oxidation micron membrane characteristic is guaranteed to have good water, and can be the perfect way to undertake nanometer material transfer of infiltrating microarea performance, thus realize the change to the graphic pictures of information transfer area, will eventually network information transfer to Nano ink Nano printing material that is a kind of based on nanotechnology high-tech products: nanoparticles scattered to ink later, can control the ink performance, improve resistant plate printing Six, plate-making technology in the future Nano material the emergence of green plate-making technology, will give the world bring new changes in printing, environmental protection and resource conservation increasingly valued today, NGP will lead the printing industry into the direct plate-making ecological, digital
