Had an artist bring in prints/cards to sell, and I could tell they weren't pigment based ink. Looked like simple photocopies to me, so she called her printer store. He said they use laser toner, but had no idea about the quality of it. I bought several cards for the rack, but sent her away with the prints. Seems unwise to sell art that will fade soon (even with good glass)? But is it possible there's laser toner that does last well?
