RE: Calcomp plotter
I had tried Report Grade paper before. Normally a bit thin for me. When the postal rates went up, it used it all up, as it mede the box weight under the amount of weight for next whole pound.
Normally I use the Opaque Presentation paper. A bit thicker and still has the half tones I like. Got about four boxes stored away.
You ahd better get the rolls of paper before they are gone.
