Inks and Environmental Issues — Compliance vs. Quality

"Let's take a petroleum-based ink, which may be listed as having 25-percent VOCs. The EPA arrived at that percentage by burning [heating to boiling point] a certain amount of ink, let's say 100 grams. Those 100 grams were burned at 110 degrees for 10 minutes to see how many VOCs were released. However, presses rarely heat to 95 degrees, and that's if there's a dryer.
