I get good profiles using my i1 pro and four letter sized sheets (1848
patches including a 21 step gray scale). I used to have a ColorMunki when I
was first experimenting with Argyll and did a couple of profiles with 1568
patches (8 pages) that also seemed quite good. I suspect for RGB printers
this is the ball park that you should be looking at (I have an Epson 3880).

Subject: [argyllcms] "Magic Numbers" or Number of Patches in Targen
To anyone,
Just wondering about the "magic numbers" suggested for utilizing targen.
For a 4 page set of targets there is such a wide variation in the number of
patches depending on the device. A SpectroScan will have over five and a
half times as many patches as the Colormunki with the -h switch. Quality
differences between these devices not withstanding, will the Colormunki
profile be substantially inferior? Would I have to print 22 pages of
patches to approximate the quality of the Spectroscan?
I realize the magic numbers are a compromise between quality and paper
usage.would just like someone's opinion on this as I have a Colormunki Photo
and a DTP20 (Pulse).
