In Color mode, I have measured L* = 4.0 (d-max = 2.35) on Ilford Smooth Pearl. In ABW mode, I have measured L* = 2.9 (d-max = 2.49) on the same paper. This is getting close to the performance of dye-based inks — impressive! It may be possible to get deeper blacks on other papers or with different driver settings.
