I have measured dmax on several papers that I have used frequently. For those who are unfamiliar dmax is the reflective density measurement of the deepest black that a paper will achieve. Higher numbers indicate a deeper black.
Oriental VCFB 2.14
Oriental (Grade 2) 2.10
Azo (Grade 2 and 3) 2.07 and 2.09
Kentmere Fineprint VC 1.97
J and C Polywarmtone Classic VC 2.04
All of these are excellent papers. Today was my first experience with the Kentmere paper. It appears to have a more abrupt toe as it separates high values very nicely.
