I just got a spectrophotometer to go along with my colorimeter!

Anyway, why buy a color checker when I have a spectro and I can profile my printer - why don't I create my own test patches? They should be very close, correct?

The Color Checker system has very precise color swatches that the included software presets will calibrate to. The software will only work with the passport since it's specific colors it's profiling. The system can be good for getting quick color calibrations for color spaces on your computer. Calibrating your display to have consistent color with your printer is a separate matter, but yes....calibrating the monitor is the first thing I do when I get a new computer.

It takes so long to do it well! Profile the colori with the spectro, apply that correction and then use the colori to calibrate the monitor. Takes me about 3-4 hours per monitor (I have 3 monitors and use almost 5,000 color patches), using DispCAL - but the results are almost infinitely better than what I get with the X-rite software (which actually made my calibration worse than default.) Anyway, that's off-topic.

How lasting are the color checkers? I'd expect them to develop a yellow tint over time?

Yeah, I don't spend that much time and resources with my monitor calibration. Only slight color difference I see with my screens is my uncalibrated iPhone, which is just slightly cooler then my computer displays: only really apparent if you're directly comparing side by side.

As for the permanence of the passport....I imagine YMMV! Keeping it stored closed and in your bag's pocket should last awhile. X-Rite does give them version numbers, though, and they claim they update them. I don't know how much is actual improvement or marketing to get you to buy the new version.

Suppose I'll be bagging the one that came with my spectro.

Icor1031 are you using dispCAL in Linux?

No, I don't like nix. But, I am using DispCAL and Coloris.

I dunno... I use the color munki photo myself... takes a few minutes to hit the screen... takes about 20min to calibrate the printer to the ink and paper type. There about. I find it simple enough and close enough to my needs.


My entire hobby of gear lust has temporarily been shifted into overload. Please be patient while my mind tries to get back onto the road to recovery. We do apologize for any inconvenience this may cause....
