So is this problem? Well it could be if you are trying to print to exactly match the CMYK and white paper Lab figures from in the curent ISO 12647/2 2013 standard.

Many will remember the ‘comfort’ of reviewing transparencies on a lightbox, and comparing them with proofs and printed sheets in light booths. What simple, happy days.

This is a small and very quick blog on the subject of when to change D50 tubes, to ISO 3664, in order to maintain colour accurate viewing conditions.
Well, the tube manufactories state a life of 2,500 effective hours. Of course the tube life is much longer, but they are not colour accurate after [...]
Well, there are many colour management issues, but the one that comes up time and again, even from printers with a good colour managed workflow, is the management of colour within PDFs supplied by their clients.

1. A rip is not a workflow!
The wide format rips from the [...]
The blog is based on a briefing paper I wrote for CMA Imaging, so is published with many thanks to them.
For the last few years the International Standards Organisation, the ISO TC130 international committee, which develops all the printing industry related standards, ISO 12647, 12646, 3664, etc, has been slowly amending [...]
I have heard this comment too many times over the last 15 years, so I have, at last, been moved to briefly discuss why this is wrong.
It has been said that a digital image without a profile is like buying a burger from a dodgy burger van; is it beef, lamb, dog or [...]
