Instantprint offer great artwork review for NOTHING whereas many printers make a surcharge for the same. Not only is it free, but it is done well.

Previous print job's background changed hue and I wanted to ensure that this one would not be the same. The artwork team fielded the questions promptly ... albeit that given I do not have access to CMYK output ... it might be not quite what I wanted, the last job (and hence this job) will be acceptable.

With other printers, I've had terrible results arising from not using their costly artwork review add-on. Instantprint do it as part of the service.

Great help from Liam, Beth and Brooke the latter on a website error. They promptly sent the help information which is inaccessible due to the error.
