Target patches: random/scrambled or ordered?

It depends on the printer. Some printers that have vertical dampers (aka, the 3880) have pressure differences on the left and right of the printed page (thus more ink that prints). This results in jagged measurements if the patches are not scrambled.

Because scrambling the patches does not decrease quality (no matter the printer) but does help with things like ink pressure variance in the printer, I always turn that on.


In another post, Walker suggested using scrambled target patches when creating your own ICC profiles. I have been getting what I think are pretty good results using between 1600 and 2200 patches using ordered patches.

What am I missing? Would I be better off printing scrambled targets? If so, why?
