Pre-Press - Computer-to-plate

VANCOUVER, BC—Creo Inc. is claiming victory in the wake of a district court ruling that six Agfa patents for computer-to-plate (CTP) technology were unenforceable due to acts of inequitable conduct. According to a statement from Creo, the ruling by the U.S. District Court in Massachusetts determined that Agfa failed to disclose known material information to the U.S. Patent and Trademark Office. "We are extremely pleased with this ruling as it supports what Creo has maintained all along," notes Creo CEO Amos Michelson. "Agfa's patents would never had been issued had Agfa told the patent office the complete facts on the development of automated CTP technology." Agfa

by MaRK SMITH Technology Editor Weak strains of the great violet vs. thermal CTP debate cropped up in some post-Drupa reports, and then were echoed in postings on the PrintPlanet.com "Computer to Plate Pressroom, CTP Technologies" eCommunity and other industry forums. These discussions largely have covered old ground, but two pending developments are seen as having the potential to change the competitive picture. CORRECTION:Heidelberg announced a new option in its Prosetter violet platesetter line prior to Drupa, which should have been included in the printed version of this story. With the new Multi Cassette Loader (MCL), any Prosetter can now image up to four

BY MARK SMITH Technology Editor At the risk of having this sound like yet another Drupa story, the quadrennial international exhibition traditionally has served as a status check for industry innovations. Developments in printing technology often are marked in "Drupa time"—such as the Digital Printing Drupa, CTP Drupa and, for this year's show, the JDF Drupa. The concentration of international vendors and worldwide attention given the event put pressure on exhibitors to show that they are keeping pace with each other. While not as broad-based of a trend, 2004 also heralded the Processless Plate Drupa. This technology has been talked about for years,

BY MARK SMITH Technology Editor The size of a shop's presses used to be seen as saying something about the sophistication of its operations. Today, half-size and smaller presses are just as likely as full-size machines to boast sophisticated computer controls, digital interfaces and other automation features. While the trend toward shorter runs may play to the strengths of these presses, print buyers don't want to make any compromises in color, quality or service. Therefore, small- to mid-size printers have come under increased pressure to be technologically competitive throughout their shops. For a growing number, a critical step has been adopting computer-to-plate production with

BY MARK SMITH Technology Editor The goal is basically the same regardless of what name is given to the technology—no-process, process-free or non-process plates. Since computer-to-plate production is all about taking steps, variables and labor out of the workflow, it naturally follows that people would look to eliminate the chemistry-based plate processor. The leading plate manufacturers have very similar takes on the future of this development, even if they differ on what to call it. This shared vision begins with a focus on non-ablative switchable polymer and/or on-press development systems as promising technologies. That is, with the exception of Presstek Inc. in Hudson, NH.

BY MARK SMITH Rarely does the first generation of a "revolutionary" new technology live up to expectations. In software circles, for example, painful experience has taught many users to wait for version 2.0 of any new release. The saying, "Once bitten, twice shy," definitely applies. The greater the degree of disappointment, the longer the road will be to convincing potential adopters that a technology is now "real." Both stochastic/frequency-modulated (FM) screening and high-fidelity/extended gamut color separation technologies first made a lot of noise in the market during the mid '90s. Versions of each achieved some success, but both have been seen as failed technologies

BY MARK SMITH Maybe the time has come to start an industry support group. "Hello. My name is Tom, and my print shop has yet to install a computer-to-plate system." Actually, a large number of U.S. printing companies are still making plates conventionally. There are perfectly valid reasons for not having made the move to CTP-based production, but probably not since high school have printing managers felt so pressured by the notion that "everyone is doing it." With some fits and starts, CTP has gone mainstream faster than many predicted. Today's buyers include shops on their second or third generation of technology, along with

BY MARK SMITH Printing is one of the few places where eight is a magic number. Even the once standard eight-hour day for many has become an artifact of a simpler time. Eight-page production, however, continues to be the standard of comparison for most facets of the printing process. For a time it seemed to be the de facto size for computer-to-plate (CTP) solutions. Eight may indeed be enough, but it also can be too little or too much. Two-up platesetters actually helped pioneer the direct-to workflow and technology, albeit using paper and polyester plates. Small-format metal systems have been a more recent

Computer-to-Plate Has Positive Effect NEW YORK CITY—TrendWatch Graphic Arts has released its first report focused exclusively on direct-to-plate technologies. According to the market report, the once doubtful commercial printer community has overwhelmingly begun to embrace and benefit from the now decade-old technology. Among the survey findings cited as supporting this conclusion are: * 39 percent of all print businesses perceive direct-to-plate as having a positive effect in their operations. * 55 percent of sheetfed offset press shops perceive direct-to-plate as having a positive impact on their business. * An additional 17 percent of sheetfed press shops plan to start using digital plates, while

PITTSBURGH—Do film-based plates require fewer remakes than digital plates? A survey of 29 companies conducted by the Graphic Arts Technical Foundation (GATF) and the National Association for Printing Leadership (NAPL) produced some interesting results. Participants were asked to choose from a list of likely causes of plate remakes and record them for 30 consecutive days. In all, data was recorded on roughly 55,100 plates (42,600 digital and 12,500 film-based). The leading remake causes for film-based plates were plate wear (17.7 percent), voids (8.1), register (6.6), plates not stored (6.2) and changed press (5.5). For digital plates, the top causes were plates damaged on-press (9.1
