Clearprint Vellum
Clearprint's coating is an impregnated coating which means the coating is all throughout the sheet rather than coated top and bottom.
What this allows is the ability to make ten consecutive erasures in any one area without any ghosting (copying) in the reproduction process.
Your coated top and bottom Vellums literally imbed your pen or pencil image into the surface resulting in poor erasability. Coated Vellums also yellow and become brittle with age.
There is no replacement for the quality of Clearprint Vellum.
