Fons Put works as senior innovation consultant for VIGC, the Flemish Innovation Center for Graphic Communication. His contribution refers to the new colour measuring equipment (eXact from X-Rite) that WAN-IFRA has chosen for the evaluations for the International Newspaper Color Quality Club 2014–2016 contest.

Depending on the device measurements can be different.

Here is Fons Put's comment:

In order to help some newspaper publishers to evaluate their instruments, I created a worksheet were they can compare spectrophotometers. Our first impressions:

  • The i1PRO1 resembles the best WAN-IFRA measurements of the Cuboid with the X-Rite eXact.
  • The i1PRO2 (XRGA) has a different response, we're not advising this for INCQC measurements.
  • The old i1PRO1 (revision AB) gives the same response as the newer i1PRO1 (revision D).

If you like to see the figures, take a look at the spreadsheet:
