Purple laser CTP full line debut

It can be seen from drupa2004 that CTP is still coexisting with thermal and violet laser technology, but violet laser CTP develops rapidly. Some manufacturers that originally only produced thermal CTP have now introduced violet laser CTP. The original manufacturers of visible light CTP are almost Both have introduced the violet laser CTP.

Purple laser CTP full line debut

With the development of violet laser technology, Inner Drum CTP has successfully launched a violet laser CTP with a 30mW diode imaged on a photopolymer plate, which greatly improves the platemaking efficiency; the appearance of a 60mW, 100mW violet laser diode extends the lifetime of the laser diode to 1 Million hours, the replacement cost of diodes also dropped below 10,000 euros.

Fujifilm Film Co., Ltd. LuxeIV-6 internal drum type four open CTP adopts the company's Brillia LP-NV photopolymerization plate making, after printing, Naiyin resistance to 1 million printing, its equipped laser diode life exceeds 5000 hours, the highest resolution Up to 3657dpi, output 1400dpi output 35 sheets per hour, 2400dpi output 20 sheets per hour.

Agfa exhibited thermal CTP at drupa and also demonstrated violet CTP, Polaris's upgraded PoIaris XTV-S and XCV-S violet CTP. XTV is 25% faster than XCV per hour. Can make 260 sheets (1016dpi). Agfa said that 36 purple laser CTPs were sold to newspaper users and 21 purple laser CTPs were sold to business users.

Japan screen 2 violet laser CTP: eight open PateRite Micra violet laser CTP, four open FlatRite 2055Vi violet laser CTP, 60mW diode PlateRite micra can be exposed to violet laser photopolymer, plate format from 250mm X 330mm to 516mm X 580mm.
Esko-Graphics has a variety of different formats of semi-automatic, fully automatic violet laser CTP, among which new products are PlateDriver Compact and DPX 4 polyester CTP platesetters.

Krause exhibited a LaserStar violet laser CTP capable of exposing 250 photopolymerized plates per hour while also introducing a 100mW laser diode light source that can be used for any direct platemaker. The diode light source has a lifetime of 10,000 hours. The replacement costs about 9900 euros.
Compared to the thermal CTP system (platemaking machine, plate), the violet laser CTP is cheap and has medium-format printing, such as eight open, four open, split and large format, and the advantage of violet laser CTP plate and equipment gradually appear. In the area of ​​large-format printing, thermal CTP technology still occupies a dominant position.
The CTcP technology imaged on the traditional offset printing plate also shows a growing trend and is a strong competitor of the violet laser CTP. Both Esko-Graphics and basysPrint have demonstrated mature CTcP platesetters and continued to increase product development and marketing efforts.

Purple laser CTP plate boosts

The plate used for violet laser CTP has two major categories of photopolymerization and silver salt. Due to environmental issues and the continuous increase in power of CTP violet laser light sources, the development momentum of photopolymerized CTP plates has become increasingly strong due to many reasons:

1. As the power of the violet laser light source is increased, the photosensitivity gap between the photopolymer plate and the silver salt plate is closer.

2. The imaging mechanism of the photopolymerizable CTP plate is the same as that of the negative PS plate. By alkali development, the graphic part is composed of an oleophilic resin. The printability is the same as that of the PS plate, and the operation is more convenient for users who are used to the conventional PS plate. easy.

3. The use of photopolymerized CTP plate will not produce heavy metal waste, which is conducive to environmental protection.

Japan Fuji Film Co., Ltd. was the first to launch a violet laser photopolymerization CTP plate at the drupa exhibition in 2000. As a joint venture between China and India and Japan Fujifilm, Fuji Starlight has adopted Fujifilm's advanced technology. The domestic production of violet laser photopolymerization CTP plates is scheduled to be available at the end of 2004. The product name is tentatively LP-NVA and has the same performance as Japanese LP-NV.
