Photoshop CS5, and later versions CS5.5, CS6 and CC removed the option to print without colour management in their print dialogue. Although this doesn't change how most people will routinely print images, it does make printing profiling targets almost impossible with that software. To allow profiling targets to be printed easily without applying any colour management Adobe released a free utility just for this task, Adobe Color printer utility.
It's downloadable from here.
Most Mac users need to use this utility to print profiling targets as it seems to resolve all the issues we've recently seen when printing targets with Macs.
For PC users there is a bug in the software that means the targets are printed without the correct margins and are resized slightly smaller. We've extensively tested this and, in this specific case, it doesn't give us any problems with building a custom printer profile. If you do use this utility please ensure that you mention that you're printing from this on your order form.
