The Paper Chase for Inkjet
On the uncoated paper side, Finch Paper’s strategy for high-speed inkjet printing is to optimize the benefits of different ink technologies—such as dye-based and pigment—via distinct paper formulations, rather than offering a “one-size fits all” stock.
Finch also offers custom solutions for specific customer needs, such as fine-tuning the paper chemistry to control dot fidelity.
Formulas for Success
Philip Hart, director of product marketing, says Finch inkjet papers do not have to be certified by each press vendor, but Finch Performance Inkjet Papers are qualified at OEMs and undergo trials at customer sites. An additional surface treatment is not needed for these grades, he adds, since they are manufactured with specific formulas to maximize ink holdout and drying at high print speeds.
Georgia-Pacific offers two specific lines of uncoated papers for web inkjet presses—one for dye-based and one for pigment-based devices. According to Kelly Ferguson, director of public affairs and communications for Georgia-Pacific, standard paper grades offer better print quality on pigment-based inkjet presses—like the HP T-series and the Kodak Prosper—if a bonding agent is applied, typically on the press.
The manufacturer has also developed Spectrum Web Inkjet with ColorPRO Technology for high-quality printing on pigment-based presses without the use of a separate bonding agent. Stocks that carry the “ColorPRO Technology” designation have met a set of quality specifications defined by HP and verified by the Rochester Institute of Technology’s Printing Applications Laboratory.
For dye-based presses such as the Kodak Versamark, Océ JetStream and Screen Truepress, Georgia-Pacific offers Spectrum Web Inkjet DB converting papers to support water-fast monochrome printing applications.
Domtar has engineered specific products that offer fast drying and water fastness properties to perform on the latest generation of continuous-feed inkjet presses. Its products are designed to function in most presses running either dye or pigment inks. Surface treated grades are also available for the presses that perform best with enhanced products.
