per card. There is also the issue of inkjet prints fading over time. Cards
from a print shop may eventually fade, but not nearly as fast (unless your
printer uses pigment-based ink).
The QSLs I received from my first QSOs 30 years ago are surviving nicely.
Ironically, the newer cards aren't doing nearly as well.
Mostly, the problem seems to have to do with computer-printed report
forms and stickers. The ink on dot-matrix ribbons seems to be rather
susceptible to fading. And more than one QSL with the report form
printed on a mailing label seems to have lost its label.
Ink-jet printing also seems susceptible to damage from moisture. Get a
bit of water on it, and who knows what'll come out!
