Purple laser CTP can give newspaper users the most satisfactory answer. This is why newspaper users are rushing to the violet laser CTP. The following is an analysis of the application of violet laser and thermal laser in newspaper CTP.
1. Production efficiency and production cost 1 Different laser technologies and their production efficiency Purple laser CTP with purple laser printing plate is currently the most productive solution. For example: Agfa Advantage Purple Laser CTP, 30mw single laser head speed can reach 160 to 220 four-hour output per hour, if using thermal technology, 50w single laser head CTP output efficiency is 100 per hour Zhang Sikai Edition; thermal CTP with 40wX2 laser head can only reach the output speed of 150-180 sheets per hour, while the violet laser CTP of 30mwXi laser has a production efficiency of 350 sheets per hour. This is because the exposure energy required for the thermal plate is 160-170mJ/cm2, which is much higher than 0.05mJ/cm2 for the violet laser plate, a difference of 3,000 times.
The service life of the violet laser and the thermal laser has a very big gap: the service life of the violet laser is 10 years, and the life of the thermal laser is 2 to 3 years. The cost of replacing a thermal laser head is tens of thousands of dollars, and for a thermal CTP that has an output speed greater than 100 sheets, there is only one change. Therefore, the thermal CTP is used at the cost of a huge use cost in exchange for production efficiency.
2 Different laser technologies and their production costs Production costs should include: equipment depreciation, equipment maintenance and consumables, and consumables include: CTP plates, potions, and laser replacement costs. The sales price of purple laser CTP and thermal CTP, which are similar in configuration and degree of automation, are not much different, and the cost of the plate material and the plate solution are also quite similar. There has been debate over the consumption of liquid chemicals. The actual situation is that the total consumption of the washing solution of the violet laser photopolymer and press thermal plates is about 80m1/m2, including the loss of the replacement medicine, flushing and oxidation. supplement. In fact, this is expected because the newspaper thermal plate is essentially a photopolymerized version of infrared light. However, there is a huge gap in laser replacement costs. Taking a two-laser thermal CTP as an example, if 25,000 m2 of plates are exported each year, 180 plates are output per hour, and the lasers (double lasers) are replaced every three years, then the lasers are distributed on each plate. The cost is about 10 yuan/m2.
Comparing the use costs of all the above factors, we can see that the use cost of violet laser is the lowest, followed by green laser and thermal laser. This is the main reason why 90% of newspaper industry CTP users choose violet laser CTP.
2. Production reliability Newspaper printing is different from commercial printing in that it has a particularly high reliability requirement for production. Five minutes of production delay due to equipment failure cannot be tolerated. Violet laser: 30mw power, simple optical path and circuit, long service life; thermal laser: 20-50W ultra-high power, water cooling system for laser cooling, complex spectroscopic systems and circuits, very short The service life. The reliability of violet lasers in actual production is much higher than that of thermal lasers. Therefore, newspaper users who place production reliability on a very important position usually choose the Purple Laser Press CTP.
3. Productivity Because the exposure energy required for the violet laser plate is only one thousandth of that of the thermal plate, the production efficiency of the violet laser is much higher than that of the thermal laser with the same number of lasers. Single laser: 365 shots per hour for violet lasers and 100 shots per hour for thermal lasers: Four lasers: 350 shots per hour for purple lasers and 180-200 per hour for thermal lasers Zhang Sikai.
4. The quality of newspaper printing Today's newspapers have increasingly strict control over print quality. Some newspapers even use semi-commercial web presses to print magazine quality ad inserts to meet advertisers' requirements. The high imaging quality of the violet laser CTP, the high resolution of the violet laser silver salt version and the photopolymerization version are sufficient to ensure that the high quality requirements of the newspaper can be met under the premise of high production efficiency. For the thermal newspaper CTP to meet both high quality and high speed, users have to pay a much higher price.
5. Supply of CTP Plates Almost all newspaper CTP users hope that the supply of CTP plates used is open, that is, different suppliers can be selected for supply, so that the price is more reasonable and the supply cycle is more secure. At present, almost all mainstream CTP manufacturers produce violet laser CTP plates, such as Agfa, Fuji, Mitsubishi, etc. Kodak Polyray, which originally produced only thermal plates, will also launch violet laser photopolymer later this year. Version. Only Creo still insists only the production of thermal CTP, but this has seriously affected the market share of its products. It must be noted that the plate used for press thermal CTP is currently only produced by one manufacturer, while the newspaper thermal plate is a completely different product from the normal plate, and cannot be replaced with each other.
