Hi Hal, Robert seems to have re-engineered Gutenprint's settings system by shifting to XML and ripping the hard-coded stuff out of the code into parameter files. So it should be possible now to create tools for domain-experts to use. I'm sure that Robert would be very happy to get guidance from anyone who knows how users expect to do things. I had Xrite send him a donated EyeOne Pro spectro so he has the tools he needs. Edmund Hal wrote: > About the only things I have changed are the density and ink limits.
