Color verification and compliance tools are gaining in popularity and print buyers are realizing their value. What's not to like? Buyers can put their newly-learned color and G7 ideas to work, ensuring their print procurement is consistent and pleasing to the eye.


Some buyers are taking their vendor's advice and requiring printers to use specific software tools or cloud services. This creates an untenable situation where printers have to buy, learn and use multiple tools in order to gain the customers' work they need. A vendor representative recently confided "We have printers who are required by customers to buy and use 4 or 5 different color compliance products in order to print their work. It's insane and unnecessary."

Don't torture your print providers by requiring proprietary tools' measurements for compliance testing.

What many don't realize is that color verification math is essentially open-source. The formulas, units, and tolerances are available to everyone and most tools use the same foundational tech. How they differ is in their approach to the problem, their workflows, and their levels of automation and reporting. (have I mentioned recently how awesome Maxwell and Curve are at such things?)

This means that the foundations exist for the many verification tools to share data easily. Thankfully, Idealliance and ISO have created standard file formats that allow this very exchange to occur: PRX and PQX. PRX (Print Requirement eXchange) and PQX (Print Quality eXchange) are standard XML file formats created by Idealliance to allow for the clear exchange of print requirements and the resulting print quality measurements.
