Digital BW, The Print

Have you tried making your own ICC grayscale/ toned profiles with Profile Maker or Datacolor? K3 inks being what they are should change from printer to printer. Could it be that the print head is just not up to snuff? 


I don't have a 2400, just a 4800 in the new K3 line but I don't see that issue.

  I found my ABW prints to look quite artificial. They were excellent in neutral, but I did experience the ABW as a little over blue. I was quite put off.

  For purely economical reasons initially, I shifted to Paul Roark's UT-3D inks and workflow. That gives beautiful cool black prints. I think its quite a challenge for the Epson driver to mix in just enought blue pigment without it showing. MIS did the mixing already, so the effect is more subtle

  I agreed with everyone who I have heard say that 2400 with K3 is amazing. It is! But in my experience shifting to the Eboni-based UT-3D inks took me to another level entirely.

  Subject: [Digital BW] color casts in ABW?

  I'm printing in ABW mode on an Epson 2400 with Epson K3 inks.

  My prints often have a very slight bluish color cast in the shadows; when I
  stare at the print for a few minutes, the effect is enough to make them look
  slightly hand-coloured. It's only noticeable on prints in which there's a
  smooth gradient in the shadow tones (eg in a darkening sky, or around the
  hairline in a portrait). Spectrometer readings show the effect as a dip in B*
  of about 2 points at densities between 70% and 90% typically.

  Has anyone else been bothered by this effect? I'm not sure if I'm expecting
  too much from ABW; given that ABW uses standard settings for all papers
  with a given media type, I'd expect some color shifts across papers, but I'm
  surprised that it looks so bad. And I see it even on EEM too, albeit to a
  lesser degree than on Entrada and Photo Rag.
