The base media is a 335 micro caliper, 320gsm alpha cellulose with atrue baryta coating. It is being made available in A4, A3. A3+, A2 sheetsand then 17”, 24” and 44” rolls (on a 15m run and jumbo core). In hand the print is quite stiff and we used the fine art feed on our Epson 4900.
The media whiteness parameters are tabled. We also compared the new media with an FB silver halide print (probably Ilford FB Multi Grade of 1995 vintage).
The spectrum charts are revealing for although the old silver halide material has a higher OBA activity, it is significantly less bright in visual terms and behind on the Whiteness, Brightness and Luminance values. The statistics show a greater difference than you might suppose from looking at the prints in the viewing booth although the Fluoresence values match what the eye sees.
