Whether it is a CTP system or a film-based workflow, the quality of imprinting is the most critical. Here are some of the plates developed by manufacturers that contain the latest technology.
Presstek Corporation
Anthem Edition: The surface of the wet offset hot plate is processed into granules and anodized to be compatible with various types of fountain solution and ink. With a print rate of 100,000 sheets, no preheating equipment is required, and no developer and post-development baking oven are required.
Agfa Corporation
Mistral: A dry, undeveloped plate that offers the best quality and highest print rate. It is based on advanced thermal ablation technology, allowing plates to be imaged and ready for printing in minutes (without chemical development), and Mistral's screens can be more than 300 lpi.
Thermolite Edition: For short runs, on press or offline imaging. Agfa uses a traditional aluminum-based technology and coats it with a layer of heat-sensitive material. Thermolite is imaged by thermal exposure of the emulsion layer and can be imaged on the press. Its wetting characteristics are exactly the same as in traditional printing plates; the non-porous coating on aluminum substrates is a hydrophilic coating.
Lithostar Ultra: Positive aluminum version that can be combined with a variety of visible light imaging technologies. There are three models: Lithostar Ultra
LAP-V (Purple Sensitive/410nm), Lithostar Ultra LAP-O (Positive Sensitive/488 nm and 532 nm), and Lithostar
Ultra LAP-R (red light/650 to 670 nm). It can be used on Agfa's latest violet lasers Agfa Galileo VS and Galileo VXT.
Agfa N91: Negative-tone aluminum version for visible (488 nm and 532 nm) platemaking systems, including Agfa's Polaris series. Can be used for long-lived, in the case of network cable number of 175lpi, the copy of the network range is 2% -98%, the printing rate of up to 300,000 printed sheets without baking.
LiteSpeed: A rewritable spray imaging plate is under development. Based on Thermolite technology, a chemical coating applied to a metal substrate (print plate) on a printing press, imaged, printed, removed, and then re-sprayed for waiting for the next imaging.
Thermostar: Agfa's unbaked products, up to 500,000 sheets, eliminating the need for pre-baking and other steps.
Kodak Polychrome Graphics Free Plate: This is a hot, negative plate that can be exposed digitally to an external or built-in hot drum with a residue removal/filtration system on the drum. This printing plate has a printing resistance rate of 50,000, which is suitable for various ink and water balance conditions without preheating, developing, coating or baking.
CTPI: Previously used Thermal Printing version / 830, the Compact Thermal Processing System (CTPI) is an all-in-one device and chemical system that includes a preheat module, a hot plate developer, and an optional post-baking resin coating unit (fast Baking unit).
Aries Excel: A positive-working plate for medium and long-lived printing, 150,000 (no baking), 600,000 (baking).
Thermal Waterless Plate: Thermal imaging is brought into waterless offset technology with a printing resistance of 200,000.
UP3: Positive printing plate, used with UV and metallic inks and UV coating, compatible with fine, traditional and random screens.
DirectPrint: Negative plate type printing plates, which do not require pre-press development, can be imaged on the press without chemical composition and developer.
PDI
PDI is also a manufacturer of hotplates. Prisma thermal imaging plates can be exposed at 830nm laser (Creo-Scitex) without pre-baking and post-baking, printing with very little water , greatly reducing the preparation time before printing and the wear of the drum.
Fujifilm
Fujifilm's digital plate Brillia line is also based on aluminum, the same as the traditional PS plate line.
Brillia LP-NS: Negative, high-speed photosensitive polyester plate, when the number of screen lines is 200lpi, can copy 2% -98% of the dots, using argon ion (488nm) or FD-YAG (532nm) light source, can Used with various types of chemicals.
Brillia LH-PI: Positive edition for the Chinese version. When the number of screens is 200lpi, 1%-99% of dots can be copied without prior and post-baking. Use the 830nm IR laser for exposure. .
BrilliaLH-NI:IR laser-sensitive negative pattern type, suitable for the long version of the live version, when the number of screen lines is 200lpi, can copy 1% -99% of the dot, without prior and post-baking, use 830nm The IR laser is exposed. Recently Fujifilm made some improvements to the plate.
Mitsubishi Imaging
SDP-Eco 1630: Black-and-white and spot color CTP applications for small format presses. High-speed winch technology. Outputs 78 plates per hour at a resolution of 1,200 dpi, which is two thirds less than analog systems. Developing chemistry, which includes a stand-alone developer, two new developers specifically designed to handle the company's Silver DigiPlate or polyester plate.
DPX Platemaking System: Developed by Purup-Eskofot, it features a built-in roller and produces a four-color plate width of 18.1 x 21.6 inches.
ABDick and MEGAPro Polyester Edition for Digital PlateMaster (DPM) Direct Plate Making Equipment Line.
DPM2340: A narrow-width, inner-drum system featuring 3600 dpi and 45 plates per hour.
DPM2000cp: integrated fast version of the built-in scanner: Scan hard copy to direct plate-making equipment, not in Photoshop.
