surface to engrave. This allows the engraving machines to provide more consistent quality as well as maintain smooth cell tops. In a printer’s world this could mean a lower roughness of the anilox surface, longer blade life, and reduced scoring. Harper globally has also extended its XLTTM technology with nine new state-of-the-art versatile ALE Hercules laser en- graving systems, five of which are 500 watt models. There are also plans to add another four lasers in the next 18 months. Harper’s 500 watt fiber optic engraver contains the latest laser technology available. As CO2 laser technology became obsolete in the anilox world, the new fiber optic technol- ogy became our standard. Low line screen engravings with extended or extreme volumes were at minimal a challenge when using CO2 technology. However, with the 500 watt fiber optic technology we are not only able to achieve standard low line screens but have been able to expand our engraving charts beyond what was previously possible. Harper is able to now achieve a broader range of engravings with our XLTTM, XVRTM, and LaserKote product lines. We offer more extensive engraving ranges than any other anilox manufacturer. Harper’s laser technology goes much deeper than just the wattage of the lasers. The cell profiles are much more defined, and tops of cell walls are much more crisp and smooth. Harper has pioneered and still strongly supports the 60 degree hex as the premier engraving geometry being offered to the industry. It is not possible to make consistent engravings if you are unable to consistently measure the line screen and volumes. Harper was the first anilox company to embrace and use Interferometry, which the FFTA Flexo Quality Consortium (FQC) committee has listed as the most repeatable method to measure anilox volume at the 2011 Forum. Harper exclusively uses 3DQC’s from MicroDynamics. Every anilox we engrave is set up in the laser using 3DQC measurement verification prior to engraving and then checked across the anilox surface after engraving. Harper has also developed and incorporated an internal proprietary software package to work with the 3DQC. This proprietary tool allows us to maintain a consistently smooth surface after engraving, which will help rolls perform with less wear, scoring, and provide extended performance. n About the Author: Lee Kluttz, is vice president of operations at Harper Corporation of America.

HarperScientific LauncHeS innovative aniLox Stain removing pad Global anilox roll supplier Harper Corporation of Amer- ica is excited to announce the launch of the X-CelTM Pad. Developed by the HarperScientific division, the X-CelTM Pad is the most revolutionary way to remove stains from an anilox surface. The advantage of this product lies in its performance. Developed to micro scrub the anilox surface and release the stain from the ceramic, the X-CelTM Pad is typically used with water or solvent. “ We have found the X-CelTM Pad enhances the cleaning power of anilox chemicals and assists in breaking down the bond between the stain and the ceramic,” says Josh Kiser of the Harper GraphicSolutions team. Printers will find the X-CelTM Pad to be easy to use with cleaners like Ceram- Clean-IITM. Furthermore, it easily removes both surface stains and blemishes on ceramic. The X-CelTM Pad is another example of HarperScientific’s commitment to devel- oping products for its customers that will increase pressroom efficiency. www.flexography.org june 2012 FLEXO 9 Harper corporation of america earnS eSko certification, forgeS aHead in digitaL fLexograpHy Harper Corporation of America is constantly innovat- ing the products and processes within the flexographic field. As the rest of the world embraces the digital revolution, so, too, has Harper Corporation. Now Esko certified in HD Flexo, Harper Corporation of America is continuing with its mission of providing the highest qual- ity service and products to its clients. HD Flexo is the latest prepress revolution in flexography. This digital process creates flexographic plates, which are more consistent than standard digital plates. Additionally, HD plates result in higher quality, clarity, and vibrancy. In addition to being on the cutting edge of technology, HD Flexo is an environmentally-friendly and efficient so- lution for flexographic organizations looking to improve their operations. This process can be integrated into printroom procedures without having to replace exist- ing equipment or operational policies. As a result, the transition to HD Flexo is smooth for both flexographic professionals and their clients. Harper Corporation of America received Esko certifi- cation in HD Flexo in January of 2012. This certification is used with XLT 60° high end anilox rolls. The engravings range from 900cpi to 1600cpi and are perfect for both narrow and wide web markets. By combining Harper Corporation of America’s precise anilox roll engravings and Esko’s prepress technology, Harper’s customers are able to produce superior ink release, consistent printability, and exceptional print quality.
