This fascinating discussion is going to make me late to exercise class
(exercise the body --- sooooo much nicer), but I must say that one of the
substrates NOT giving me even steps and not as many is *Pictorico* -- I'm
printing on Epson 1160.
I gather that the step tablet I made with a change of 5 degrees with the
little thingy on every step isn't the right approach for digital... I
couldn't open your curves, however Dan -- in your CD: They were marked
AVC or like that & my %$#@&*^%$#@!()&%^%$##!! new system 9 informed me,
honey we don't recognize that ...
later,
