Digital BW, The Print

Hi Richard,

That's an interesting artifact.  If you print a smooth ramp, do you see a vertical line or other abrupt change or bump in the ramp?  A linearization problem might cause the problem, but it's a bit surprising it shows up only at that post edge.

> I have just noticed that with QTR I am seeing a strange appearance in prints with abrubt tone transitions. It looks like QTR is trying to sharpen the image and is losing the smoothness of the transition, resulting in a double image. It's not happening with Advanced Black and White.
