One other package that has been welcomed by many as an
indispensable
additional tool are the Roman16 reference images, see:
http://www.roman16.com/en/
a series of 16 images each focusing on an important aspect of color.
Makes it easy to spot overall 'inconsistencies in color reproduction.
HTH.
I love the roman16 images! Sehr shoën. I askd bvdm when they will print the
images on Type 1 paper and they soon.
