Polarized CTP Technology Today's CTP technology can be divided into two major categories: thermal and visible light.
Thermal CTP is a system that uses laser thermal energy to form an image on a printing plate. It was introduced in 1995. Due to the material's ability to operate in the bright room and excellent printing performance, it has occupied a considerable market in a short period of time. In 1999, 50% of the total global CTP demand was the thermal version. Creo, Canada, is a major manufacturer of CTP. In the summer of 1999, the company’s CTP system had sold the 1200th unit. The company also achieved impressive results in 1999. The report shows that the sales increase is about 40%, and the profit growth is about 30%.
At present, the plate material manufacturers are basically producing thermal CTP plates, of which the most representative is the Thermal-830 plate produced by KPG. They introduced the improved Thermal-830A in November 1999. The new thermal plate does not require heating and water development and can be called a dry thermal plate. After that, although companies have introduced thermal plates without preheating, the mainstream product on the market is still the Thermal-830.
There are various kinds of light sources used in the visible light system, such as a 780 nm semiconductor laser, a 633 nm germanium laser, a 532 nm FD YAG laser, a 488 nm argon ion laser, and a visible light corresponding thereto.
It is currently known that the silver plate and photopolymerization plates are mainly used in photoprinting plates, and the aluminum plate is generally used for silver salt CTP plates. However, the silver salt plates of polyester substrates are used in short plates in CTP plates. About 20%. The photopolymerization plate, like the conventional PS plate, is coated with a photosensitive resin on an aluminum substrate, so it is generally considered easy to grasp.
The three types of printing plates mentioned above, ie, silver salt plate, photopolymerization plate, and thermal plate, can be found in each of their specialties, but there is no big difference. The main criteria for assessment are summed up in the production costs and the suitability of the light room operations.
Before the first half of 1999, it could be said that the thermal CTP was in its golden age and showed a good momentum of growth, especially in the United States. It was also the world of thermal plates, with a market share of about 60%. This is mainly due to the fact that the temperature-sensitive version of the thermal plate is superior to other plates, and secondly because the thermal plate has won the GATF award.
Visible light direct plate systems in Europe and other regions have maintained more popularity. European and Japanese manufacturers have been working on the development of photopolymerization and silver salt plates. U.S. material suppliers have a special liking for thermal plates. According to this, in the United States, the thermal CTP is positive, while in Europe it is Visible light CTP scenery is infinite.
The biggest news in 1999 was that some big newspapers in various countries competed to purchase CTP systems. Nearly 200 Taiwanese companies, such as NY Taiwu and USA TODAY, were introduced. And these newspapers basically all use the visible light CTP system. Because for newspapers, the output speed is the first one, and as long as the resolution is half that of ordinary printing. The output of the plate is required to reach more than 100 pieces per hour. Now the highest speed visible light CTP system, a newspaper version can reach 240 high-speed output per hour. However, if the same version uses a thermal CTP system, only 80 sheets can be output.
Due to the expansion of the market for printing press systems in Europe, since the second half of last year, the visible light CTP system has returned with a comeback and the trend will change. Of course, according to recent statistics, the range of thermal sensitivity will soon exceed 50%, and the 21st century will be the era of thermal sensitivity. However, the status quo is that the CTP market will continue to expand in the fierce competition between visible light and heat. In 1999, the number of global CTPs was set between 3,500 and 4,000, and in 1998, the number was 2,500. More than 40% of the rapid growth, Japan's possession of 200 units.
Debut of Blue LD CTP (blue laser diode)
The development of CTP technology has been declining, but the development of new aircraft types is still very active. Last year, more than 16 new products were also released. However, half of them are new models for newspapers.
ECRM has launched a high-speed Hologon CTP for newspapers that costs $100,000. Akron Tech also successively introduced the high-speed, low-cost CTP with the newly-designed HIogon Morror.
In addition, the KPG company puts on the market and the price of the thermal CTP is about 100,000 US dollars. The system outputs plate speeds of 80 sheets per hour. In the past, the price of this pair of CTPs was 150,000 US dollars, but in less than 1 year, the market price has dropped by 2/3. In this way, if the CTP exceeds 3,000 units, the price will be lower.
However, last year's top news was the high-speed CTP built by Escher-Grad with Blue LD: Cobalt-8. The CTP with its built-in Blue LD was exhibited on drupa, but it was actually launched half a year ago.
The Cobalt-8 uses a rotary laser head, which scans 18 sheets per hour at high speeds, so it may be the highest speed CTP system, even higher than the highest speed CTF imagesetter, and even more remarkable is the use of silver salts. The version can be operated under the yellow light, and the Cobalt-8 is published as a hand-operated model, which poses a great threat to the thermal CTP.
In addition, the photopolymerization plate used was manufactured by Fujifilm, Japan, but it was quite surprising that it could also be imaged at such low power as 5mw.
