On the left is one I just printed. The one on the right â€” same printer (HP Photosmart C5180), same paper â€” has been taped to the glass on our front-facing screen door since December 2007, in full sunlight. It’s barely legible. (And yes, it has slightly different fonts/layout; the original was done on a PC in OpenOffice, the replacement in LibreOffice on a Mac.)
So whenever an inkjet crows about “Archival Inks!”, remember: four years to fade to white. Do you need your images to last longer?
