By Paul Sherfield On 11/03/2020 · Leave a Comment

Well, yes and no, not a lot for the past few months on my site. However, this is mainly due to me writing for FESPA, as their Colour Ambassador and for the Konica Minolta user group, Prokom.

 There is lots of content covering many areas of colour management on both sites, including training videos and [...]

Hunkeler Innovation Days – February 2019

By Paul Sherfield On 04/04/2019 · Leave a Comment

After visiting this year’s event I came away wondering if this was the time when continuous feed inkjet presses took their place as a creditable replacement for sheet fed offset litho in the most demanding commercial printing markets?

By Paul Sherfield On 20/07/2018 · Leave a Comment

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.

Has ISO 12647/2 2013 become regionalised?

By Paul Sherfield On 05/02/2018 · Leave a Comment

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 [...]

The Power of Grey and Black-updated 9/2017-UV curing and ink costs

By Paul Sherfield On 20/02/2012 · Leave a Comment

Update 9/2017

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, [...]

CMYK colour gamut’s, digital presses and brand and special colours

By Paul Sherfield On 14/06/2017 · Leave a Comment

 

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 [...]

The standard range [...]

Fogra 51 and 52 profiles do not match ISO 12647/2 2013

By Paul Sherfield On 19/08/2016 · Leave a Comment

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 [...]

Screens-the starting point for colour management?

By Paul Sherfield On 17/06/2016 · Leave a Comment

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 [...]

By Paul Sherfield On 05/08/2015 · Leave a Comment

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 [...]
