The ones I made for the SpectroCam may be usable for you. Only 
the linearisation/profiling targets. So I didn't do the ink 
limiting, curve creation targets as I find it easy enough to 
do it per patch on the maybe 20 patches scattered over that 
target.

I'm thinking of an improvement on the random 
linearisation/profiling target to keep errors down in strip 
reading, the contrasts between patches isn't always high 
enough for my SpectroCam to switch to the next patch.


Met vriendelijke groeten,  Ernst
