In order to have a bigger patch size to read, I crop the target with 
only the patches & numbers left. From photoshop, select [print with 
preview] & have the following setting : [scale to fit media], [let 
photoshop determine color], [working rgb-adobe rgb(1998), [saturation]. 
Of course i won't forget to turn the [color management off] in the 
printer driver.  So will the above setting produces the same result as 
printfix pro? 

My 2nd question is : our local sales rep suggests to use [saturation] 
instead of [perceptual] when printing with printfix created profile. Is 
that true?
