About ten years ago, the entire printing industry was still looking forward to the era of CTP-free. After experiencing the initial confusion and chaos, the printing house has now been able to choose its own product from a variety of printing plates and plate-making machines. Some printing plates do not need to be processed completely-they need to be rinsed with a potion used after imaging or developed with a fountain solution on a printing press-but this printing plate also has certain environmental and cost-effectiveness.
The durability of current processing-free printing plates can reach 100,000 prints. Ray Cassino, head of pre-press products at Heidelberg, said: "We first saw the rapid promotion of chemical-free technology in the quadruple printing plant." He attributed the rapid development of this technology to their small size.
Jack Wiethoff, Global Manager, Digital Printing Plates, Kodak Graphic Group, said: "We designed the processing-free plates specifically for small to medium-sized printing houses." He added that although Kodak can now provide two types of purple laser plates, But they still insist that for most customers, thermal sheet is a good choice. In the following, we will highlight some of the newly launched thermal-sensitive CTP technology without processing and chemical-free processing and the emerging purple laser printing plate.
Agfa
Agfa's: Azura (chemical-free printing plate system has been in use in more than 300 printing plants and prepress companies worldwide since its launch in November 2004. It was originally used as an Ag heat-sensitive CTP plate-making machine The only solution: Azura plates can now be used with multiple brand platesetters, such as PlateRite for screens, Trendsetter and Lotem for Kodak, Expose for Luscher, and Topsetter and Suprasetter for Heidelberg.
Susan Wittner, Agfa ’s marketing manager, explained: “Azura plate is not a closed system-it can be used on any plate-making machine. Users who already have a thermal CTP can also get rid of the trouble of processing the plate, Use Azura plates in their own plate-making machine. In short, Azura plates do not require you to prepare special equipment for it. "Azura (Green Star Plate) is a granular anodized aluminum thermal plate, which is obtained using The patented ThermoFuse technology can form images without undergoing chemical treatment. One only needs to take a clearing step to enhance the contrast after the printing plate is imaged. In addition, Azura plates can also be processed in daylight.
At the Ipex exhibition, Agfa will launch a new generation: Acento and Palladio quadruple or B2 format CTP system. Users can upgrade the Acento II E system to the more productive Acento II S system. The new cylinder balancing system makes it suitable for a variety of small format printing machines. It is said that Acento II can generate a thermal digital printing plate under the laser irradiation of 830 nanometers, and the printing plate size is between 12.75 x 14.56 inches and 25.98 x 32.67 inches, which can meet the needs of small to medium-sized commercial printing and packaging plants The production demand of the edition.
Fuji / Enovation
Fujifilm's Brillia HD PRO-T processing-free thermal printing plate launched on PRINT 05 is now in the (software) beta test phase and will be officially launched on the market on April 1, 2006.
In addition, Fujifilm is also developing a non-ablation chemical-free printing plate made of photosensitive resin. This product is expected to meet you in 2007. It will have many of the features of Fujifilm's existing LP-NV printing plates, such as: the ability to print with UV inks and solvent inks without drying; Extraordinary durability and can be processed under yellow safety. It is said that the development of this product mainly depends on the commercial application of high-energy violet laser technology.
Fujifilm's new processing-free printing plates are based on a new high-definition printing plate emulsion layer technology, which allows the performance of the new printing plate during printing to be basically the same as Fuji's existing CTP The printing plate remains consistent. Brillia HD PRO-T is compatible with most thermal (830 nanometer) platesetters, and can clearly reproduce 1% to 99% of the dots at a resolution of 200 lpi, or can be expressed at a resolution of 300 lpi It produces mixed and FM screened images. It is a non-ablative printing plate that can carry a latent image that is convenient for people to check after imaging. When used on a printing press, the Brillia HD PRO-T printing plate will be stained with ink and fountain solution, and only a small amount (similar to the traditional PS or CTP printing plate) of printing paper can be used to enter full-speed production. status. MultiGrain technology also enables it to achieve excellent water-ink balance like Fuji's existing CTP plates.
It is said that the exposure of Brillia HD PRO-T printing plate is similar to Fuji's existing thermal printing plate, which is about 120 mJ / cm2, so its production speed can be consistent with the existing printing plate. This printing plate has a durability of 100,000 prints, can meet the needs of most commercial printing plants, and can be processed in the sun.
Brillia HD PRO-T printing plates can be used on a variety of plate-making machines, but it is best to use Fujifilm's Dart and Javelin thermal CTP equipment.
Fujifilm's quadruple Dart series thermal plate-making machines-Dart E and Dart III-the maximum speed of the drum rotation is 1,000 rpm. With a 32-channel laser diode exposure head, the Dart III can output 20 four-page printing plates per hour at a resolution of 2,400 dpi. Dart E has a 16-channel laser diode exposure head, so it can produce ten plates per hour as above. Dart III claims to be able to produce larger format printing plates and is suitable for medium-sized printing plants.
Dart E was also released on PRINT 05. It can be used with processing-free printing plates, and it is suitable for those printing plants that adopt CTP technology for the first time, because its price is relatively low, less than 90,000 US dollars.
Presstek
Presstek's Dimension CTP system and Anthem thermal plate can provide users with productivity and quality while bringing high ease of use. Presstek's Anthem anodized aluminum chemical-free printing plate has good water-ink balance performance and is compatible with a variety of printer chemicals. After imaging, this printing plate only needs to be rinsed with water, without baking or gluing. It can only be imaged by laser irradiation from 800 to 1,200 nanometers, and it can be processed in daylight.
The Dimension Excel platesetter can now output two-page and four-page plates, and can be configured as standard (Dimension225 and 425) or high-productivity (Dimension250, 450) equipment. These devices have a very small size, and are very suitable for use with Presstek's chemical-free Anthem plates and Applause metal plates without processing.
Presstek's chemical-free Freedom thermal plates can be imaged on the Vector TX52 platesetter suitable for small format (less than 52 cm) printing houses. If you want to know more about this product, let us pay attention to the IPEX exhibition that will be held in April.
Kodak
Kodak's Thermal Direct process-free printing plate was officially unveiled on PRINT 05. It has a traditional granular anodized aluminum surface, so it can be pre-coated with aluminum plates to make it look and feel. According to Kodak's introduction, Thermal Direct plates can be compatible with almost all mainstream CTP platesetters, and can be used with a variety of inks and fountain solutions.
Thermal Direct has a unique thermal coating that is 70% thinner than ordinary photosensitive violet laser plates and 38% thinner than typical thermal plates that require processing. Applying resin to the printing plate prevents the coating of the printing plate from being dissolved by the fountain solution of the printing press.
Kodak also reduced the coating of colorants on Thermal Direct plates, thereby eliminating the potential risk of glazing on the ink rollers, while the colorants it retains are still sufficient to produce clear images to facilitate the determination of the plate on the printing press cylinder Is the location on the right?
This printing plate can reach 100,000 prints under ideal printing conditions, and can reproduce 1% to 98% of the dots at a resolution of 200 lpi. It is said that Thermal Direct can be processed for one hour under white light or four hours under yellow safety light.
The Thermal Direct plate is part of Kodak ’s All-in-One process-free product package, which is a complete four-page CTP prepress solution, which includes a Magnus 400 imaging device and a Prinergy Evo PDF processor.
Heidelberg
Heidelberg released the Saphira Chemfree chemical-free printing plate to users worldwide on PRINT 05. This negative-pattern sand mesh aluminum version is sold together with the Heidelberg Suprasetter platesetter.
This new printing plate was developed based on the Saphira Thermoplate PL of the Speedmaster SM 74 DI press. Saphira Chemfree chemical-free printing plates use a new latex coating technology called microspheres. This coating is non-ablative and can eliminate the variable factors in the traditional thermal plate processing process. Suprasetter's patented thermal laser (830 nanometers) can fuse the microspheres on the underlying metal and expose the printing plate to form a printed image.
Suprasetters of Heidelberg can provide customers with a variety of functions in plate processing, format conversion and punching, and has a variety of models, from the basic model of 4 or 8 pages to Single Cassette Loader (SCL) and fully automatic Multi Cassette Loader (MCL), etc., can meet the needs of different users. The new internal punching method used by it can ensure the precision of punching to the greatest extent, so that it can maintain the best registration status with Heidelberg and other printing machines on the market.
Heidelberg also independently developed a new type of laser, which is said to bring superb imaging quality and maximum productivity. At the same time it can increase the output by adding modules. Intelligent Diode System (Intelligent Diode System) can ensure the continuous production, even if the diode fails, it will not cause much impact on production performance.
