Not a snappy title but it covers the issue I wish to discuss.
Many printing markets, such as packaging, point of sale and areas of the commercial sectors, due to the demands of the client, need to match brand, Pantone and other colours very accurately, often within De2000 2.5. This is a very [...]
So why does PrimaPress need a ‘special’ profile?
PrimaPress is a lightweight uncoated (LWU) mechanical paper with lightweight coated (LWC) properties. PrimaPress has a brilliant print gloss, high whiteness, opacity as well as with excellent runnability. It is for heat set web offset production and designed to replace lightweight coated papers.
The standard range [...]
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 current ISO 12647/2 2013 standard.
The reason for the difference is, in itself, reasonable. The white paper Lab figures for the 8 ‘new’ papers in the standard, called [...]
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.
But how many transparencies or colour prints do we see these days; very few I think. Over the last 12 years, digital photography has taken over in both [...]

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.
This area can cost printers hundreds of hours and tens of thousands of pounds in unrecovered costs [...]
Colour management is a maturing technology, based on the International Color Consortium (ICC) specifications. Most graphic arts software uses ICC colour management to control the display, colour space conversion and output of colour.
These include desktop publishing packages such as Adobes CC suite, Quark Express and Coral.

Colour accuracy, consistency and appearance are becoming an increasing requirement for all areas of printed products. The wide format market cannot stand apart from this issue. This blog looks at how a colour-managed workflow can save money, assure quality and retain 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 [...]
Yes, it’s the revised ISO standard printing conditions for sheet and web fed heatset-offset litho. The revision was published at the end of 2013 and is available from the ISO web site.
This blog will look at the main changes to the revised standard and the new data sets and profiles being [...]
