FLEXO Magazine : June 2012
Technologies & Techniques The Evrollution of EFlo-HDTM Anilox Technology for HD Printing By Dave McBeth Flexographic printing has made tremendous technical advances in the last 15 years. Today, the process has grown to the point where it is now the most popular package printing process in many print segments globally. High quality flexo printing is now the norm— rather than the exception—around the world. Press technology in conjunction with advanced anilox roll interfaces have made this achiev- able, moving design away from gravure to a 10-color or more flexo process. Demands for higher quality have seen HD Flexo becoming the new key driver within the industry. HD Flexo has taken problematic designs (such as flesh tones) and raised the bar in tonal reproduction using new screening techniques and finer dots on the printing plates. This has also been a challenge for anilox manufactures: to be able to manufacture finer screened rolls that will work with these new technologies. Over the course of the last 10 years, offset and gravure have seen more and more printed designs moving to flexo. Designs once only gravure or offset were ca- THE NEW STANDARD • Demands for higher quality have seen HD flexo becoming the new key driver within the industry • Over the course of the last 10 years, thanks to HD flexo, offset and gravure have seen more and more printed designs moving to flexo • Independent market research indicates that 45 percent of the global marketplace has anilox rolls incorrectly specified for CTP plate technology of plates higher than 120 lpi • EFlo-HDTM Anilox, at a lower BCM volume and higher line screen, allows the ink to transfer at a much better rate • Superior densities and contrasts at higher line screens alone are just some of the attributes X Custom software and modern-day laser optics now afford flexographers the opportunity to manipulate and control laser engravings at previously unprecedented levels. HD flexo anilox roll specifications are critical to success. 60 FLeXO june 2012 www.flexography.org
