| I keep my scans in RGB but do a so-called black and white conversion in Photoshop, usually using the LAB conversion method. This leaves an adjustable colour layer on top for tone, which you can set to a pure grey or black, or something warmer or cooler. Scans done this way are indistinguishable from grayscale, but far more flexible.
Most people print on inkjets nowadays, and no inkjet does good pure black and white without using expensive Piezography or MIS inksets, so Mike's idea of duotoning (or tri- or quadtoning) is a good one - duotones print very well on most decent inkjet printers. |
