There are obviously many colour management and printing resources available on the internet.  Below are a few of our favorites including shops we use, reviews we read and printers we use when outsourcing

Jack Lowe Studio (excellent for digital black and white and alternative process printing)

Keith Cooper's Northlight Images (good for equipment reviews)

Neil Barstow's Colourmanagement.net (HUGE resource for all things colour management)

Colour Confidence (good online shop for buying professional gear)
