Digital BW, The Print

I wasn’t suggesting WIR tests. I suggested independent side-by-side
comparisons under controlled conditions.  Show the comparative deltaEs.  No
extrapolations, just comparative performance tests.  Nice and simple. That
will sell.  The rest won’t, at least not here. It’s your call whether you
listen to your audience or not....

Thanks for your advice.  However, all our published testing is done by
independent third parties to internationally agreed standards.  If we
think the "... King is naked", we will say so, irrespective of group
sensibilities.

We use hard scientific data and then seek independent corroboration from
respected independent organisations.

As a matter of record, we use The Printing Industries Research
Association International (PIRAi) and Leeds University Department of
Colour Chemistry.  Incidentally, both organisations use the Blue Wool
Scale test together with Delta-E readings; as does The Society of Dyers
and Colourists.

I think it is disingenuous to suggest Image Alchemy is somewhat
eccentric in preferring to use scientifically sound research, carried
out by reputable and independent research organisations.

I do have a problem with Wilhelm Imaging Research (WIR) stating that so
and so ink will last X number of years before fading.  We know that
Lyson's Fotonic ink was accredited by WIR as having a life of 70 years
and yet in an independent test carried out by Leeds University's
Department of Colour Chemistry, the magenta and light magenta inks
failed to get past BWS 2!

My contention is that many organisations use WIR to give them a level of
credibility that they often don't deserve.
