Digital BW, The Print

No this is MPS Black with Piezography GO. MPS is designed to be overprinted with Piezography Gloss Optimizer.  It can hit that with or without composite - but needs GO (or a spray).

I think Epson Photo Black is more desirable for color printmakers because of its dye content - it can hit a better dMax without need for GO as a result of dye. Yes its weak on matte... 

If its longevity, I do not think longevtiy is an issue with black and white printmakers using color inks - or they would not be using color inks in the first place. So the MPS does not add anything to their mix either.  If longevity is a factor - I have some WIR i-Star metrics on MPS vs Photo Black. But its just a performance on the fade of the black position so becomes irrelevant in the overall picture. The Epson ABW shifts color rapidly even as it does not lose density (which explains the high Wilhelm results.)  B&W printed with color inks and ABW has very poor longevity performance when color shift is measured and not just density. Wilhelm of course only measures density in all of his v3.0 testing procedures.

And as just a PhotoK replacement for a color ink set to make color prints - I am not certain what advantage MPS would have over Epson Photo Black.  A matte/gloss replacement black just does not seem feasible because Epson uses the cart chip to allow the use of matte or glossy settings... 

The majority of Epson color ink customers who are using Piezography inks in conjunction with their color set have replaced the Epson MK, LK, and LLK with my Neutral K7 shades 1, 4, and 5. Some others have replaced with Selenium versions of these shades depending upon their preference for B&W. My understanding is that they are using a strong loupe and using ABW to eliminate any CMY inks. The Neutral inks also allow much better ICC profiling because its easier to create a neutral axis by using neutral blacks instead of the tinted Epson blacks. So we are selling them into CMYK shops. Most of the gloss users are just buying shades 4,5 which are thin enough to allow gloss CMYK proofing.


Maybe if you tell me by what criteria you are making decisions for a black replacement? unless I hit it with one of the above scenarios...

I would think all of the K3 printers would jump at the chance of using this black ink. If it is compatible with color inks, I might just try it out on my 2400.
