"He who marches out of step hears another drum." ~ Ken Kesey
ditto what Tony says. Your inks won't produce enough dynamic range, so your prints will get muddy. Even with at least 2 screens, where the second screen is only the darkest parts of the image, will increase the depth. You also need to back down the image using curves (or levels, but I prefer curves, a bit more control). I'll bet some of artists like Scott, ArtElf or Dot-Tone Dan may have an extra trick up their sleeves...Steve
And Pierre, I'd give at least 3 cents for any info you wanted to impart...Steve
