Sun Chemical demonstrated productivity and quality gains for the corrugated market provided by its Advantage and Everest Hi Tone ink systems showcased at the SuperCorr Expo 2004.
    
In addition, Sun Chemical and its partner, Inca Digital Printers, highlighted further advances being made in the design of the high-speed, fixed-array FastJet ink jet printer for corrugated products, which was introduced in May at Drupa 2004.
    
Sun Chemical’s Advantage is a water-based flexographic ink formulated for pH stability during long press runs of mid- to mid-high level corrugated and paper bag products. This creates consistent on-press performance, while reducing the need to constantly adjust pH in order to control viscosity and print characteristics.
    
Everest Hi Tone inks were developed by Coates USA. They are water-based flexo inks designed for vignette and process printing on paper and board for pre-print, multiwall bag, post-print and narrow web applications.
    
“These two ink systems represent substantial opportunities to improve print quality, run consistency and pressroom productivity across a wide range of paper packaging applications,” said Jim Wegemer, director, paper packaging, Sun Chemical North American packaging inks.
    
He said that Advantage offers consistent color strength and good coverage with very clean printed results. Due to the ink system’s stability, monitoring at press side is reduced, minimal viscosity adjustments will be needed, and consumption of additives will be reduced. Advantage rewets well after shutdowns, but still dries quickly for good in-line die cutting on a variety of substrates.
    
The vehicle structure in Everest Hi Tone provides clean printing with crisp print definition and excellent rewetting for high-end prints, Mr. Wegemer said, adding that this ink system can be used on most coated and uncoated paper and board substrates.
    
The FastJet ink jet printing system for corrugated is being enhanced, and should be ready for commercial introduction in 2005, according to Mr. Wegemer. It will employ UV inks printed through a fixed array of print heads for high speed four-color printing with 300 dpi resolution.
    
“This combination of UV and digital technology will provide converters a high degree of flexibility for short-run or customized packaging,” Mr. Wegemer said.
