Sigma™ Black for heatset & coldset Newsprint
Send me more info about this product...
Sigma is our very popular heatset web black for low-quality uncoated and newsprint stocks. Sigma delivers the smoothness, density, blue tone and low-linting of a more expensive heatset ink at nearly newsink cost! Sigma prints a dense, even, very flat, dull finish perfectly suited for rough uncoated and news stocks especially in the halftones. The vehicle system in Sigma is truly superior to common newsinks. Sigma can also be run without heat at high speeds, setting within minutes to a scuff and smear-resistant finish just like a heatset ink. As you can see, this makes Sigma a multi-purpose economy black for almost any web service on news-type paper stocks. Sigma is also available in a bluer-toned version as a "Special Order" item.
