Colour Audit

Although there is no need to do so, we bespoke profiled both surfaces and then audited the output. Gratifyingly the new PermaJet product out-performed the Ilford on 29 of the 30 parameters we normally table, indeed the overall error, at 1.84ΔE₀₀ was one of the lowest that we have measured. Thus the PermaJet performed flawlessly - by way of example the errors in chroma and hue were nine hundredths of a percentage point where a difference of 1% is the visual detection limit!

Overall then a top-notch performance. We also tested results printed at PermaJet using the same profile and set-up. The difference between the two prints averaged a little over 1.5 Lab points, in other words, near-identical response. The gamut volumes of our bespoke profiles were close, the PermaJet was an insignificant 1% smaller. The metamerism of the PermaJet media was lower than Ilford although both recorded low values. The Dmaxes were identical.
