In the audit tests this material was marginally the worst of the group, returning errors of 7.8 Lab ΔE/3.56 ΔE 2000. The shadows retained detail to 25RGB points, the highlights to 250RGB points. The Granger Chart was smooth and there were no visual discontinuities in the greyscale gradient. The loading difficulties which forced us into using the front, board-loading may have influenced this result although there was no over-spraying visible in the samples other than the black text. We went back and retested using the rear manual feeder. The results were visually similar other than the cleaner text.
Once the paper is underway through the Epson 3800 it seems to become smaller and is actually quite manageable.
Museo Pan Pro Paper
This is a 365gsm paper specially cut and packed for large-scale panoramic images. It is 13 inches by 40 inches and substantially packed in 25 sheet quantities. In the hand it is quite a substantial paper with a luxurious feel - it could not fail to impress. The media is archival standard, 100% cotton rag, acid free and buffered. It is free of optical brighteners. The surface finish is described as 'velina' and is a slightly creamy colour. The surface texture is quite subtle and undulating.
On colour audit the profiled paper returned average errors of 6.1Lab ΔE/2.9 ΔE 2000. The Dmax was 1.43, metamerism was 1.6 Lab points. The shadows retained detail all the way down to 15 RGB points; the highlights up to 520 RGB points. The gamut volume was 544,910, placing the media in the middle of the pack for Epson 3800 printers using fine art type media. The Granger Chart was clean with no discontinuities other than some slight patchiness in the deep browns and blacks. Like some of its siblings, the profile/paper combination exaggerated posterisation in skin tones on Relative Colorimetric rendering intent but not on Perceptual intent. This is not a paper issue - an image one!
Overall then, a media free from any vices which will be of great interest to monochrome landscape workers wishing to make big impressive pans!
