Excellent decription. Makes me more confident with reading my
patches and not being overly anal about the whole thing. I do know
at times however that a printer can have trouble with the heads or
there can be a very minute amount of gunk on the paper that will
cause an anomaly in the reading apart from just missing patches etc..
My idea with throwing out the anomalies of three patch readings would
catch either situation although a careful examination of the patches
beforehand should ceratinly suffice for print problems on the
patches... What you say makes sense. Nothing to worry about.
Bravo on a great product. I've been printing with my dj130 now for
quite awile using default profiles and resisting the urge to get
custom profiles made (because I wanted an i1 in the past.) Now after
just one day with the PrintFixPro I feel like the last 20% of the
printer has been unlocked. I printed a photo heavy on browns out
last night that the custom HP profiles had destroyed. In the past
the colors looked aweful and I thought the browns were just out of
gamut for the printer or something. After profiling with PFP the
image is AWESOME! It looks just like the monitor. A little darker
because I'm viewing under standard lighting. Thanks for the great
product. Anyone using the default HP profiles for designjet printers
really NEEDS one of these.
