6:00 pm – 8:30 pm COMPLIMENTARY “TASTE OF ST. LOUIS” DINNER While you’re getting a sample of new color theory & technology at the conference, why not also sample (and savor) some of the best cuisine the Gateway City has to offer? The dinner will feature a true St. Louis barbeque, complete with sliced brisket, pulled pork and carved turkey breast accompanied by smoky, bourbon-molasses and chipotle sauces. Sides include roasted onions and bacon, whipped buttermilk potatoes, and cornbread and biscuits, just to name a few. And no dinner party would be complete without an assortment of cobblers, cakes and pies made available to your palate’s content. Bon appetite! WEDNESDAY, OCTOBER 12 8:00 am – 9:45 am CONTROLLING COLOR ON PRESS Opacity and Color Inkjet technologies have successfully ingrained themselves as the de facto proofing standard for commercial and publication grade offset, litho and gravure markets. They’re now poised to deliver the same degree of color control and consistency to the packaging and flexo proofing market. With the advent of affordable printers capable of white output on clear and metallic substrates, inkjet proofs offer a compelling cost and time-savings. This session covers the practical considerations of setting up a white inkjet proofing system, including hardware and RIP software selection, substrate considerations, and color management issues. FIRST considerations will inform and guide us in making our choices in order to ensure a successful implementation of these new technologies. Son Do, Rods and Cones Final Analysis: FQC UV Ink Spitting Project The process of inking an anilox roller, shearing off excess ink with a blade and transferring an ink film is the foundation of flexography. Unfortunately, sometimes this process does not behave as one might expect. A recurring challenge for flexo printers is the UV ink spitting phenomenon. To combat this problem, the FQC assembled a team of industry experts to study and analyze data generated from ink spitting trials. The outcomes were reviewed by statisticians and based on resulting data, solid recommendations were identified to address this phenomenon once and for all. Sean Teufler, Harper Corporation of America Advances in In-Line Color Measurement & Monitoring in Package Printing Color quality is a key issue in all package printing, regardless of the print process. More complex substrates, shorter run lengths, higher quality demands, as well as increased reporting demands all make matching color more challenging than ever before. How do printers/converters meet these demands in a practical production environment? During print makeready, gaining color approval is the last process creating waste. In flexo printing, register and pressure are in acceptable ranges in 100-200 meters of material, but color matching and approval can take thousands of meters to achieve. Tools for measuring and monitoring color are handheld devices used off-line and RGB cameras and spectrophotometers used in-line. This presentation covers the pros and cons of each approach and illustrates the latest developments in in-line color measurement. Randy Freeman, QuadTech, Inc. SESSIONS IN DEPTH
