Digital BW, The Print

Hi,
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.

I'm using Ordered Dither algorithm, 1440 Super, Unidirectional.

I've uploaded the images, a crop of the original, and 1600ppi scans, to this page:

Any advice would be greatly appreciated.

thanks,
Richard
