<excerpt>But what about scanning say a salt print (or other
alt-processes) with a HP Scanjet 4c (or probably worse: a photocopier)?
</excerpt><<<<<<<<
With new scanners, the light source is fluorescent which does not
generate heat and there is only one pass for all colors, so the time
required to make a scan is insignificant insofar as affecting any print.
I am presently doing research on the stability of the various types of
prints (but particularly those created with dyes, such as inkjet
printers) which I hope to have ready by this summer. I had not considered
scanners as the times and light outputs are so small.
This does not necessarily apply to older scanners which use other light
sources, nor to copiers which use very brilliant lamps, nor do I plan to
test these as there are too many variables.
