I sent you a link to some chemistry information regarding the
differences between pigments and dyes as related to inks. I do not
purport to be on expert on inks, on chemistry, on art, on
letterboxing... hell, I don't claim to be an expert on anything. I
only have the information I was taught by a reputable art instructor,
an old ratty chemistry book and Harriet, the ask-it woman at
Clearsnap (the manufacturer of Colorbox). Of course there is the
chance that any one or all of these sources may be incorrect.
Due to the fact that this really is irrevelvant to letterboxing and
it was not my intent to incite an argument, simply to correct a
previous erroneous statement, please direct further responses to my
private e-mail, not to this list.
Thanks!
