At WAN-IFRAl Kodak highlighted a 16 percent laser power improvement for both its Generation News and the Trendsetter News platesetters, allowing newspaper printers to image more plates in a shorter time. Based on the additional laser power, the throughput of the Generation News Platesetter Z-speed version has increased from 258 to 277 Sonora News Process Free Plates per hour. The Trendsetter News Platesetter V-speed version is up from 116 to 129 plates. Kodak intends to make this enhancement commercially available as a standard feature in the first quarter of 2017.
The new speed imaging technology branded by Kodak as “W speed” is another optional addition to the Trendsetter News Platesetter. When used together with the Sonora News Process Free Plate and the Autoloader option, it boosts the throughput of the Trendsetter News Platesetter from 150 to 240 plates per hour, or in the configuration with the Single-Cassette Unit (SCU) from 116 to 150 plates. Kodak also provides integration into existing plate lines with optional single or dual plate rotation. The new W-speed option will be released in Q2 2017.
“These newest enhancements to our CTP solutions are further evidence of Kodak’s faith in the future of newspaper and coldset web offset printing,” said Brad Kruchten, President of Kodak’s Print Systems Division.
Kodak has also announced recently the new, Mobile CTP Control app specifically designed for mobile devices, which lets customers monitor multiple CTP systems and receive immediate feedback on their platemaking process. The new Kodak Mobile CTP Control app will be commercially available early 2017.
Trendsetter News also features a new cooling system that, according to Kodakl improves power savings by an additional 30 percent compared to the initial design, namely down to as low as 770 watts while imaging. The platesetter also comes with a new, shorter unload table which reduces the footprint of the CTP configuration.
The company explains continuous plate production is made possible by the integrated pallet load module of the Advantage N-PL. The module supports two different plate formats – single plates and panorama plates – and allows printers to have both online simultaneously. The printer either loads two stacks of 1,500 single plates or one stack of 1,500 panorama plates. In addition, an extra 100 plates can be loaded on top.
“The pallet load mechanism is quite simple. When the CTP engine has used up its first stack of plates, it automatically puts the second stack in place to continue plate production,” said Emiel Sweevers, Marketing Manager for Newspaper Engines, Agfa Graphics. “Thanks to this continuous production, we can avoid inconvenient plate leftovers. Moreover, the Advantage N-PL autonomy of more than 3,000 plates significantly reduces the number of necessary production stops and averts manual plate-loading errors such as badly stacked plates.”
The pallet load module also enables printers to load new plates under white light circumstances, without interrupting the production process. By inserting a light protection shutter between the empty stack and the online stack, for example, Agfa explains new plates can be loaded through the back or the side of the machine without damaging the online ones with UV light.
“The plate stacks are protected by a transport harness until they are moved to the online position inside the Advantage N-PL. That, together with the light protective shutter, allows printers to load a new stack without needing yellow light conditions,” said Sweevers. “The loading possibilities of the Advantage N-PL also add to the engine’s ability for continuous production.”
The fastest XT version produces up to 33 plates per hour. The imaging technology is based on the company’s fiber-coupled LD (laser diode) recording head known from the Avalon N8-24 series. All the Avalon N4-30 models, explains Agfa, reduce power consumption thanks to the automatic Eco Mode in idle time and are available with manual and automatic plate loading.
“The Avalon N4-30 XT completes our offering in the 4-up segment supporting conventional and chemistry-free plate types,” said Bruno Lepage, Marketing Product Manager CTP Equipment Commercial & Packaging, Agfa Graphics. “Both the quality and the speed, but also the high reliability of our systems are extremely attractive to B2 commercial printers. The laser diodes enable the reproduction of sharper halftone dots, improving print quality up to Sublima 280.”
With an increased plate throughput speed of up to three metres per minute, the Attiro VHS handles plates from platesetters imaging up to 400 plates per hour, such as Agfa Graphics’ newest Advantage N-TR VHS.
“The throughput numbers of Attiro VHS speak for themselves, especially for heavy-duty printers,” said Emiel Sweevers, Newspaper Segment Manager at Agfa Graphics. “They need high plate volumes and require high throughput speeds in the complete pre-press production.”
The Attiro and Attiro VHS are built according to a cascade design concept. There are three sections; the concentrated gum cascades from the third section into the second and later into the first. The gum is therefore reused three times, explains Agfa, resulting in minimal gum consumption yet maximal clean-out effect. It allows users to save on maintenance and gum while contributing to a more sustainable prepress process.
The Advantage’s N-TR VHS nomenclature stands for Trolley Load, Very High-Speed. The trolley is designed to transport plates from safelight environment to the platesetter. This gives operators the flexibility to load the plates in a separate yellow safelight environment more efficiently, Agfa explains, in case switching to yellow safelight conditions is not possible in the room where the CTP device is installed.
“With these new systems, Agfa Graphics again shows its commitment to the newspaper industry by offering state-of-the-art CTP technology that meets the requirements of the premium level segment in the newspaper market,” said Emiel Sweevers, Marketing Manager for Newspaper Engines, Agfa Graphics.
The CRON-ECRM systems provide up to 400 lpi with 1,200 to 3,600 dpi resolution. Each system allows for options in automation, imaging head preference (UV or thermal) and up to 96 diodes.
In addition to choosing the system’s type of imaging heads (UV or thermal), users can also select their productivity requirements by modifying the number of imaging diodes. Beginning with 16 diodes (in five different diode configurations), users can choose up to 96 diodes. These individual fibre-coupled diodes also provide for redundancy.
The CRON-ECRM platesetters can be configured for manual, semi-automatic or fully automatic operation (single or multiple cassette), as well as integrated with an optional in-line punching system. CRON-ECRM provides in-field upgrade paths.
Agfa Graphics introduced the 16-up Avalon N16-80 XT thermal platesetter, which the company describes as its new range of top-line models suitable for large commercial and packaging operations.
The Avalon N16’s 16-up external-drum engine is equipped with Grating Light Valve (GLV) imaging heads, with 512 or 1,024 channels (beams). The Avalon N16 range includes four models that produce between 16 and 42 plates (1,448 x 1,143 mm) per hour. The entry-level Avalon N16-50 E (16 pph) can be upgraded to the higher speed Avalon N16-50 S (24 pph) and Avalon N16-50 XT (30 pph) models in the field. The flagship Avalon N16-80 XT produces 42 pph.
Agfa Avalon N Automation for the N16 includes internal plate punching, dual, triple and quad cassette loading and online processing. A drum auto-balance system allows switching between different-sized plates.
The Avalon N16 internal punching system performs punching for both the drum and the on-press registration, immediately before mounting the plate on the drum. By adding optional press punch blocks, imaged plates can be loaded straight onto presses with different punching.
First introduced as a product demonstration at drupa in May 2012, Esko has launched its new and unique Full HD Flexo for flexographic platemaking. The technology –building on Esko’s existing HD Flexo product line – is described by the company as a highly manageable digital workflow to achieve the combination of smooth highlight printing and gravure-like solid ink densities.
Full HD Flexo is currently installed at over 20 early-adopter trade shops and converters around the world, from sites in Brazil to Austria.
“Esko flexo customers are asking for the combination of the benefits of HD Flexo together with a gravure-like ink laydown and a fully digitally controlled platemaking workflow,” stated Jürgen Andresen, Esko Vice President, Flexo Business. “This is what Full HD Flexo brings and it moves flexo to an unseen level of quality and consistency with no need for compromises. Our unique, patented technology stretches the possibilities of flexo printing, allowing it to perfectly match gravure and offset quality for flexible packaging.”
Unlike processes that require intermediate analogue or manual exposure steps, Esko describes Full HD Flexo as the first and only fully digital platemaking workflow in the industry. Full HD plates are prepared completely within an Esko CDI imager and are immediately ready for processing after unloading.
The CDI system combines plate imaging with inline digital main exposure in one and the same device. The digital Inline UV2 exposes through an LED-array light source delivering the necessary UV power density to provide control over the polymerization process during exposure. All UV exposure settings are controlled within the platemaking workflow, which helps with stability and repeatability. The system, according to Esko, works with popular digital flexo plates and sleeves, including products from the likes of DuPont, Flint, MacDermid, Asahi.
“We went beyond the binary discussion of flat top or round top dots, and created the best possible combination of print dot structures on one plate,” stated Jan Buchweitz, Senior Product Manager Digital Flexo at Esko. “This enables to differentiate the ink laydown on the substrate for different parts of the artwork on one single plate. This is a giant step forward for flexible packaging converters as the result is high quality flexible packaging that stands out.”
Esko added a new flexographic plate imaging system within its Cyrel Digital Flexo (CDI) Spark line, which the company has given a lot of attention to since drupa 2012.
The new CDI Spark 2420 is described as a compact system for narrow web label and tag converters. “According to FINAT, global label demand across all print technologies is expected to continuously grow in the coming years, while world label demand growth for 2012/13 is approximately six to seven percent,” said Jan Buchweitz, Esko Senior Product Manager, Digital Flexo. “The CDI Spark 2420 fits neatly into our portfolio that includes the CDI Sparks 1712, 2120 and 2530.”
Esko states the CDI Spark 2420 addresses these new production trends in the label and tag market with its ability to image plate sizes up to 609 mm x 508 mm (24 x 20 inches) and also handle a range of plate materials, including: digital flexo plates, chemistry-free film, digital foil-based letterpress plates, digital metal-based letterpress plates and digital silk screens.
Understanding its customers' need to continually expand capabilities and market reach, Esko provides an imaging resolution upgrade path on The CDI Spark 2420 also provides an upgrade path for customers, who can choose between the standard 2,000 ppi to 2,540 ppi resolution system or upgrade to higher resolution systems with 2,540 ppi to 4,000 ppi or HD Flexo 4000 ppi in combination with high definition screening.
In May 2012, Esko introduced its Full HD Flexo concept for a worldwide commercial launch in 2013. The concept combines CDI plate imagers with Inline UV2 and HD Flexo technologies. Esko projects the concept will push flexo printing to a new quality benchmark comparable with gravure and offset, because it bridges the argument of flat top dots versus round top dots to create the best possible combination of dot structures on the same plate.
In May 2012, Esko introduced the CDI Spark 4835 Auto with digital Inline UV2 for flexo plate-making. The CDI Spark 4835 Auto is equipped with a digital UV back-exposure, integrates digital back exposure, automated loading, imaging, digital main exposure and off-loading to the processing unit.
In October 2012, Esko introduced its new CDI 2530 system designed as a high-quality, affordable option for small label companies in North America. Employing Inline UV1 and magnetic drum technologies, the CDI 2530 images digital flexo plates up to 25 x 30 inches. It comes with an incorporated plate loading table and an EasyClamp II drum for easier and faster plate loading, while integrating with the Kongsberg XN for automatic label cutting.
