icc profile verification kit
a simple icc profile checking kit from Pixl Aps and colourmanagement.net
how do I know my icc profiles are good?
how do I test my icc profiles?
those are very good questions.
As a result of my own experience, for example in monitor profiling, I have discovered that because of possible errors such as screen deterioration or instrument damage, even a sensor based process cannot be considered to be infallible. So, I wanted to come up with a way for clients to be properly confident about profile performance, which means monitor and printer performance - a way to assess their own workflow for accuracy. Our Verification Kit was developed in a collaboration with Thomas Holm at Pixl Aps .
what's in the kit
The kit includes an ISO standard Verified GMG Proof Print of our freely downloadable Test Image, a GATF or UGRA metamerism checker to help ascertain correct daylight viewing conditions and a download link to the kit folder containing the Test Image and PDF manual as well as a number of files and informative links to useful resources.
With this kit can thus check your own monitor screen - and, also, any printouts made in your studio, or elsewhere; all by comparison against the ISO standard Verified Proof Print. This process confirms the quality or performance of the compared device. It's even possible to assess the performance of a flatbed scanner using the Verification Proof. Simply scan, compare and assess.
how do I get one
The Verification Kit with Certified Proof Print costs 80 pounds + VAT
(UK postage included, of course we can also ship worldwide).
To get an idea how this works, you can download the our Verification Image file for free below, but if you're serious about image accuracy on both on screen and in print you'll really benefit from a proper reliable printed reference to compare the onscreen image with - that is, an accurately printed image which has had that accuracy proven against an ISO reference by individual measurement, our ISO standard Verified Proof Print fulfils those needs, so I do recommend that you buy the kit.

profiling your printer:
Making even RGB printer profiles can be pretty technical and doing it well involves some costly equipment and extensive research. RGB printers can often be profiled successfully using my postal service - you print patches as instructed and send them in to be measured, I send you back a profile.

With some RGB machines and with most CMYK printers (usually those are the ones accessed via a RIP) a site visit can be very useful. From my experience users rarely get to grips with all the options available inside the RIP software, and in many cases the software seems to almost have been designed with user confusion as a primary aim. Plus, repeated test printing, working towards final optimisation of the RIP's options and, eventually, the profile's separation settings seems almost inescapable when a really great profile is the goal.
Some users understandably want profile making equipment in house, and for some it is very worthwhile. To get the gear that really works at a pro level, though, it's quite a big investment. Scanner based printer profiling (i.e. no reading device other than the scanner) turned out to be a hiding to nothing.
