    Picture of printing ink

Green ink. And paper. Every day, every year, we try to make our environmental footprint a little smaller.

Soy. Flax, tung (Chinawood), castor, canola, and safflower. The inks we use are less harmful to the environment than their petroleum-based counterparts. 

We use Sun Chemical SunLit Diamond Ink, which has more than 47 percent vegetable content (24 percent soybean oil), and 80.37 percent total renewable content. 

Some portions of raw materials are emitted into the atmosphere during both the manufacture and printing of ink. UNH Printing uses soy and vegetable-based inks that have evolved to Volatile Organic Compounds VOC levels of 4.66 percent, down from conventional commercial inks that measure VOC levels of 25-35 percent.

Recycled paper

Recycled paper is available in all colors, including the brightest whites, and meets the highest technical standards. Tests have shown that recycled papers perform just as well as virgin papers.

UNH Printing Services offers a complete line of recycled paper, from copy bond to coated stocks. Samples are available at all of our locations.

All our copiers and printers are stocked with recycled paper containing 100 percent post-consumer waste.


Recycled paper terms

information icon

  • Post-consumer material (PCW): Paper we all take to the recycling center.
  • Process chlorine free (PCF): Recycled paper processed back into paper using no chlorine or chlorine derivatives. PCF eliminates dioxins from paper mill effluent.
  • Totally chlorine free (TCF): No chlorine or chlorine derivatives used to make the paper, which means the paper must come from new fiber.
  • Elementally chlorine free (ECF): No chlorine gas but other chemicals containing chlorine are used for bleaching. ECF paper is often misrepresented as TCF.
  • De-Inked material: Waste paper that has had the ink, filler, coatings, etc. removed in the production of recycled paper.
