John,

You could make a greyscale target for Color Center, print from that application and have it measured with the Z's spectrometer and save the measurement data for QTR linearisation. Of course measurement can be done manually with a separate spectrometer too.

I experimented with an 85 patches target, 5x 17 greyscale patches, to get data for adjusting the Qimage curves. That was not very practical due to the horrible curves tool in Qimage.

Right now I am thinking of another approach that is more a low gamut ICC profiling, addressing the total of small Lab shifts in greyscale printing.


Met vriendelijke groet, Ernst

Hi Richard,


It does have it's own built in spectro and it's own target for linerization that I've used for years. But I would like to print my own linearization target and measure manually with my I1 Pro2 spectro.

I read on the page when I bought Print Tool that it supports HP printers.

I don't really need it for my Canon because I have the TBW Bowhaus software that allows me to do the same thing.

John
