The Houston Chronicle has employed use of a Goss Metro press with digital inking, in order to reduce ink waste by 61 percent, Goss International announced in a press release.
Before the digital outfit, ink waste totalled an average of 5,500 kgs per week. Now ink waste is at an average of 1,927 kgs per week. Black ink waste was reduced the most, at 68 percent, and magenta rounded out the bottom end with a 46 percent reduction.
The conversion to digital ink also allowed for a press downtime reduction of 16 percent and a 23 percent increase in paper rolls per Web break, according to Goss.
"Ink may not be the most expensive element in offset printing, but its impact on quality, productivity and waste is immense," Michael Daniel, director of printing, said in the release.
The conversion is part of continuing development at the Chronicle to improve efficiency initiated in 2005, when general manager Matt Oliver set formal baselines for newsprint and ink waste and began tracking print productivity, using a technique called "Six Sigma."
