New White Paper Heralds Benefits of Waterless Printing versus Conventional

The International Waterless Printing Association (IWPA), a nonprofit organization, committed to promoting and communicating the benefits and advantages of waterless printing to printers, their suppliers, and print buyers, announces a newly-published white paper comparing waterless printing to conventional lithographic printing performance. The 32-page document, authored by Gene Langlais of Capricorn Research, is available exclusively through the IWPA. The results of the comparative print test are published in a white paper titled “A current comparison of waterless printing to conventional lithographic printing.”

In March 2011, IWPA conducted a G7 comparative print test between waterless and conventional offset printing at an award-winning U.S. commercial printing site using conventional wet and waterless CTP plates. Printing accuracy, stability, color control, materials consumption, and other criteria were analyzed to determine the current differential in printing performance between waterless printing and conventional offset lithographic printing processes.

The white paper reveals several key waterless benefits.

• Waterless shows an advantage over conventional offset in the color gamut, indicating that a slightly larger color space is possible with waterless.

• Color stability for waterless was better throughout the pressrun using the G7 aimpoints.

• Waterless printed with consistently lower dot gain than conventional wet offset.

• Start-up waste was significantly lower for waterless, requiring roughly 40% fewer sheets at start-up to achieve G7 aimpoint densities.

• Waterless reached and maintained target ink densities on all subsequent restarts.

The white paper, which is available exclusively through the IWPA, is available free of charge to all current IWPA members. Non-members can purchase the white paper for $149.00.

Eugene Langlais founded Capricorn Research in 2007 as a consulting firm for the printing and imaging industries. He has amassed more than 40 years of experience in the laboratory and on the manufacturing floor. He is a board member of TAGA and a member of the GATF Research Committee.

The International Waterless Printing Association is a worldwide, non-profit trade association dedicated to waterless printing and its various forms. Now entering its 20th year, the IWPA represents an extensive network of waterless printers and suppliers, while supporting the print buying community’s waterless printing needs by providing a central source of information about this innovative printing technology.
