Alejandro Renteria prepped ink stations, loaded anilox rolls mounted plates using 3M E1915H stickyback and set about bringing the job into register. Prepress work was performed at Best Label’s Union City, CA facility, where DuPont Cyrel DFQ plates of 0.067 plate cali- per with 0.22 relief were imaged at 4,000 dpi/175 line screen. Esko HD Flexo screening and FLEXRIP, utilizing IDEAlliance Curve 2 software to create G7 compensation curve data, was also deployed. The imaging device was an Esko model 2530 with Hi-resolution optics and the plate processor a DuPont FAST TD 1000. The job, as speced out: four-color process over four-color process on bright silver foil substrate (MACtac ) using high definition UV inks (FujiFilm 800 HDUV Flexo). Repeat of 17 inches. Print deck one, yellow; deck two, magenta; deck three, cyan; deck four, black; deck five, white; deck six, yellow; deck seven, magenta; deck eight, cyan; deck nine; black; deck 10, varnish (Fujifilm 800 HDUV high gloss). To accentuate laydown, Apex North America’s GTT (Genetic Transfer Technology) rolls were used on magenta, black and white stations, with magenta handled by the small designation roll and the black and white assigned medium designation rolls. Apex Ultra cell plus 700 cpi bcm/3.5 vol- ume/60 degree angle and 1200 bcm/1.4 , 1 .6, 1 .8 volume Apex anilox rolls were used in other stations. Varnish was applied with a 360 bcm/7 volume roll. Metering duties were handled by Daetwyler’s white steel, one-step, doctor blades. Curing was facilitated by IST lamps and a BST Pro Mark Power Scope 4000 was deployed to monitor the run, maintain register and identify any develop- ing print faults. “ Collaboration between our team and our ink, substrate, plate and prepress vendor partners in developing the project was fantastic. Having so many vendors on site with so much collective knowledge really helps take potential problems out of the process early on,” noted Ingle. “ We put primer on paper to make the ink laydown better and decided on a flood coat for the front. Getting things right ensures everything is clean.” PRESS, PAPER, PLATES & INK Evaluating the different aspects of the job, based on first- hand impressions of work as it progressed, were a number of Best Label’s valued supplier partners. MACtac’s Duane Stevenson recalled, “In pursuit of better print characteristics, I recommended using laminated foil rath- er than metalized paper for several reasons – the foil is thicker and stiffer than metalized paper, which was important for this project. The laminated foil offers better dead-fold for a maga- 38 FLEXO december 2012 www.flexography.org early results as they appeared on press.
