The latest products, technologies and enhancements

Print matte and gloss in one pass
Strike-Thru is based on the incompatibility of two materials: a dull varnish and a gloss aqueous coating. The gloss protects the sheet, and, as it dries, allows the matte to show through. Kustom Group (Richwood, KY), a manufacturer of printing ink vehicles, coatings and overprint varnishes, developed Strike-Thru in 2003. It also offers Kustom Kure hybrid vehicles to create gloss under UV coatings.

New line of sheetfed inks
Sun Chemical (Northlake, IL) has released three new inks: Relay, Endurance and Marathon. Relay inks’ hard-drying characteristics allow the inks to be used on all types of paper, both coated and uncoated. They are well suited for dull and matte stocks, with good rub resistance. The inks offer batch-to-batch consistency, press stability and stable ink/water balance, and they can be perfected without back cylinder or blanket buildup problems.

Endurance inks require little maintenance and will run for extended periods without operator intervention or adjustment. They are a medium-to-low tack series of process inks that can print on coated and uncoated papers without excessive blanket buildup or piling.

Marathon’s stay-open ink set is designed to minimize daily cleaning and maintenance. It offers long run capability without the need for frequent blanket washes, minimizes piling and performs well on marginal papers. The inks achieve a stable ink/water balance almost immediately for quick makeready and stay open in the ink duct and rollers for extended periods, often eliminating the need for end-of-day cleanups. The inks dry well on most papers and do not contain cobalt driers.

Ink pumping
Van Son Holland Ink Corp.’s (Islandia, NY) ink pumping systems are controlled electronically and work with completely automated cartridge-based ink dispensing systems that provide the ability to track and report usage. The benefits of using ink cartridges include virtual elimination of ink waste, faster startup time, color consistency and reduction of color fluctuations typically associated with manually filling ink color. It offers 4.4- and eight-lb. cartridges that easily fit into ink pumping systems and can be retrofitted to any press. These high performance cartridge inks offer a perfect solution for streamlining operations in a large sheetfed operation.

UV/EB curable special effect coatings
Northwest Coatings (Oak Creek, WI) introduces UV/EB curable special effects coatings, including pearlescent, glitter and color-changing effects. One color-changing effect, Phantavision, produces different effects depending on the viewing angle. High-contrast color shifts appear with sharp changes in the viewing angles, while smooth changes occur with gradual curves. Phantavision coatings may be tailored to produce a variety of different colors and appearances.

Fast drying VOC-free ink
Kohl & Madden, a member of the Sun Chemical Group, introduced Liberty, a VOC-free conventional sheetfed ink, at PRINT 05. Liberty ink reportedly dries in minutes but stays open on press. The ink contains no cobalt driers and is said to come up to color quickly, dramatically reducing start-up and running waste. Spray powder use reportedly can be reduced by as much as 50 percent. Original Smith Printing (OSP) (Bloomington, IL), a beta tester, was featured in AMERICAN PRINTER’s October 2005’s “Bright lights, better productivity.”

OSP is a 190-employee general commercial printer, one of the largest in downstate Illinois. The printer has no UV equipment on its presses and typically runs Kohl & Madden’s 725 series of conventional inks. The printer began testing the inks on the 10-color and six-color presses during July, 2005.

Any skepticism about the ink vanished when OSP ran a quick-turn job printed on coated stock. Fifteen minutes after the job came off press, it was folded and stitched. Previously the company would have had to wait two to four hours before handling the job.

Does your ink make the grade?
The Graphic Communication Institute (GrCI) at California Polytechnic University (San Louis Obispo, CA) has developed a laboratory testing service to analyze and track the most pertinent visual and functional attributes of paste or fluid printing inks. The Ink Quality Assurance (IQa) program also can track the quality of ink over time as determined through multiple tests, which can alert buyers to unannounced changes in formulation or performance.

The IQa program suite has two editions, Paste Edition and Fluid Edition. Both provide laboratory testing for hue difference, chroma difference, gloss, tinting strength (bleach test), NPIRI grind test and a detailed laboratory testing report. IQa: Paste Edition also tests for ink tack and IQa: Fluid Edition tests for pH. For more information or to submit samples for testing, contact GrCI director Hal Hinderliter at (805) 756-5170 or hhinderl@calpoly.edu, or visit http://grci.calpoly.edu.
