Hi Gabriel,
Thank you for the info and the name of the paper.
From personal experience I've found the pages of Jameco Electronics
catalogs work best for laser toner transfer. I've suspected what Gabriel
has said. The coated paper keeps the toner from bonding too tightly to the
paper fibers
Two other things that figure prominently in to the mix-
1. Not all laser copiers or printers will handle the thin paper without
adding a carrier sheet and using carrier sheets adds another set of problems.
2. Not all toners are created equal. Our old HP printer and its' HP toner
cartridges made excellent transfers, the HP cartridges for our newer HP
2100 series printer has a toner that doesn't stick well to copper and is
very brittle.
Our old Xerox copier toner couldn't make good transfers but the Canon
copier we now have does.
