- With this Lyson ink set you can achieve a limited range of "coloration"  in your B&W images like sepia, cyanotype-like blue, greenish greys etc.
-  I guess they are dye based (because they faded quite fast)
- Fading meant there was a dramatic drop in density as well as color shifts. 
  However I must admit I exposed them to "summer sunlight" during a few months, that's quite extreme.
  But in simaltaneous test with a Piezography BW print this  just showed a very minor change in the highights.
 The BW silverprint (Agfa Record Rapid / Seliumtoned) did not show any change.
