What’s a good Windows monitor calibration system? I have a client - who is a publisher (and really should know better - but he’s more admin and organising people to do stuff so I guess he doesn’t see this as an important thing to do) who is making judgements on my work on a display that is piss poor - the colours are all wrong, things in shadows in images are just indistinct or not even there and I suspect his gamma settings are all over the place.

I won’t even mention how well his printer churns stuff out. He’s looking at stuff on that too and making decisions based on the muddy mess on paper he gets.

He’d need a hardware solution, not something he can do by eye (note - his eyesight is shot to bits too - so this is working against him too - we can’t calibrate his eyeballs unfortunately).

Any work I send out has a colour profile embedded (generally PDFs generated by one of Adobe’s many fine products) - so his system needs to pick up this information and display accurately. Windows Vista.

I have an gretag eye one that's probably not sold anymore, but I believe you can download windows software for it.

ColorMunki aren't bad, and won't break the bank.
At this point, even just getting hold of a colour calibration print from one of the online services like Snapfish and getting his monitor within spitting distance would be an improvement from the sounds of it.
