Paper weight conversion chart – pounds to gsm

Digital color machines (like the Konica Minolta we have) are more particular about paper weights than our offset presses. For this reason most digital machines use grams/square meter instead of the conventional weight system. This is more accurate in the fact that it doesn’t vary from manufacturer to manufacturer. The caliper of one manufacturer’s 100# cover may be different from the caliper of another manufacturer’s paper in the same weight. No so with gsm weights.

Below is a conversion chart from the conventional weight system to gsm (and visa versa). Most production digital color machines, including ours cannot run heavier than 300 gsm stock. Using the chart below, you can see this is approx. 110# cover, depending on the manufacturer that is.
