As I have previously reported, I am having some success with the new MIS
Quadtone Full Spectrum inks and the PiezographyBW plugin (not to mention
similar success with the Epson driver for the 1160).
Here's the rub:
I have been printing a 21 step image consisting of 0-100% in 5% increments.
While the reflected image appears quite suitable, I questioned the
suitability of the output for contact printing with transmitted light
because the early test print indicated something was that something was not
right.
Not having a densitometer, I decided to take some relative readings of each
step with my color analyzer (Bessler PM2L) set to the white position. The
object was to determine the relative transmission characteristics of each
step. The object being to make sure that each step produced a seperation
similar to that of all the others.
After tinkering with this for some time and making a number of curves to
produce the desired results, it occurred to me that I might not be on a good
track. I am actually close to finalizing the curve, but wanted to hear from
some of you about this approach. FTR, I havn't made a test print of the
current curve.
Comments?
Many thanks,
Nick
