Digital BW, The Print

I've removed the HP summary stats and noted that there may have been more color in the gray patch than would be the case in a B&W workflow.

The HP inkset did not do as well on some other papers.  I do not expect it can be as tone shift free as 100% carbon on all papers and where it may be subject to atmospheric pollution.  Nonetheless, my conclusion about quality of the HP ink is best shown by the fact that I'm now using the HP PK along with Eboni in my printers.
