Well darn, but no one tried it. :(
I got one DTP70 user, a score of Eye1 users, and one DTP40 user. No
one with a Spyder. I am still willing to try it with a Spyder user (or
two!) :)
1) Contact me for master curve for your printer and K7/K6 ink
combination. I will email it with installation instructions.
2) Create a target that will give you 256 patches of RGB gray from
(0,0,0 to 255,255,255) that Spyder can read. Do NOT scramble the
logical order from 0 - 255 unless you can unscramble when you export.
3) Print this target with the master curve I supply and the
Piezography workflow for QTR (not the QTR worfkow for QTR).
4) Measure the target
5) Export me a data file according to David's instructions.
contact me off list to send this to my email address...
Thanks in advance.
