One of the issues in pursuing glossy as well as matte compatible carbon inkset is what to use to make the light blue toner. From a lightfastness perspective, I'm very happy with the Canon pigment based toner that I have used in the Eboni variable tone inksets. However, the generic base is not glossy paper compatible. For glossy paper, I've typically used and recommended the MIS amber base (same as the R800 gloss optimizer). It worked very will with HP pigments and essentially eliminated their bronzing.
I'm pleased to report the Canon based toner appears to be fully compatible with the MIS amber base. I had a mixed sample sitting idle for about 6 months. There was no evidence of sedimentation and in centrifuge testing today it did very well, about equal to an Epson UC K3 LC that I used for a control sample.
So, I'm ready to move ahead with the universal carbon variable tone inkset.
