This latest version of ISO 12647/2 standard printing conditions for offset litho was published in late 2014. The Fogra 51, coated, and 52, uncoated, colour datasets [...]
This is a small and very quick blog on the subject of how often to change D50 tubes, to the ISO 3664 standard, 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 [...]
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 [...]

This blog has been driven by my observations over last Autumns when attending a number of small but very focused and interesting events held for the printing and graphic arts community.
These included the Print Efficiency days held at Apex Graphics in Hemel Hempstead, the Two Sides seminar at Stationers’ Hall and the excellent Forward [...]
I have called these courses ‘Desktop Colour Management’ as they can cover the use of colour management in the Adobe CS/CC suite, QuarkXPress and Enfocus Pitstop.
