Earlier this year, what was formerly called the BPIF ISO 12647 Certification Scheme was relaunched as the BPIF Colour Quality Scheme.
The revision to the scheme reflects changes in ISO printing standards and aligns its documentation requirements to those of ISO 9001:2015.
This makes the scheme suitable for all ISO and bespoke printing conditions [...]
Printing across borders? It would appear not!
Firstly it would be a good idea to read my blog ‘Fogra 51 and 52 profiles do not match ISO 12647/2 2013 which is still true apart from the last paragraph!
The aim by the ISO [...]

With the increasing use of UV curing on sheet-fed offset litho presses, shown by the number of new installations and retro fits of UV curing to existing machines, the area covered below becomes very important and interesting due to the higher inks costs of the inks for all flavours of UV curing, [...]
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.
