I have observed the same thing about Ilford Multigrade RC paper. One thing that
is important to remember is that the dregree of blackening is dependent of the
paper graduation chosen. Graduation between 0.5 and 2.5 does not give deep
black rendition. 3 to 4 works fine, above that, the paper gets too hard to
render anything but black or white.
Also keep in mind, that the density of the negative plays an important role.
Don't expect the full spectre from whie to black from a soft negative.
Use the right darkroom light also.
I have produced the best black with Telenal Speed 3 (fixed grade RC paper).
Slightly underexposed and well overdeveloped, the blacks are as black as you
want them. The fixed graduation, however, required good negatives.
Hope this might help a little.
Regards
Bernd Moeller
