33 patch ColorPort

33 patch ColorPort

2010-01-20 by Walker Blackwell

Hey everyone. I've been experimenting with a 33 patch gray target for  
ColorPort/QTR because the 51 patch targets don't always work as well  
in the shadows with minute differences between patches. Also, all my  
other patch creation/reading is through ColorPort now . . .


  ----------




I decided to create the target to match the Xrite Profiler Neutral  
Tuning 33 axis setup. These 33 patches seem to create a better profile  
than 21 and linearize smoother than 51 at times (with k3 inks at least  
so far). The possibly wrong part is that the patches are untagged RGB.  
I haven't noticed any major difference between 51 patch untagged gray  
targets and 33 patch untagged RGB targets printed through QTR  
however . . . If you are interested in testing this stuff, please do.

The cool part is that your can export the data in all sorts of ways.  
CVS, Cgats (compatible w/ create icc) including full spectral data!

all the best,
Walker
