Digital BW, The Print

I've found the 2:1 dilution of HP PK with MIS glop (33% PK, 67% Glop) at 100% with QTR has a higher dmax than the 100% HP PK, no bronzing, and no more overnight dry-down than the 100% HP PK.  On Canson Baryta, the next day 33% HP/67% Glop is at 2.49 density, and best 100% HP PK, using a boost to 80% with QTR, is at 2.3. There is a visible difference.  Both approaches look very good; the dilute HP PK looks a bit better.

If the Epson driver is used, the 100% HP PK hits a higher dmax.  It's the ability to have a very high ink limit that allows the HP + GO to do so well.

The numbers suggest to me that a 1:1 mix may be even better.  I'll give that a try soon.

The 33% HP + GO on Red River Metallic comes the closest to the look of the dyes that I've seen from a pigment.  Still, however, the surface of the card is different.  With the pigs you can tell they are sitting on top of the paper.  There is a bit of a gloss differential with the pigs.  The very high ink limit blacks have a glossier look than the middle values.  On the other hand, no metamerism with the HP + GO gives that approach an advantage with fluorescent lights.
