Well, I print my targets using F-Spot, which just prints the raster
image, full bleed on the page. So I want my patches nicely centered.

For now I'm just postprocessing the printtarg output with
ImageMagick's convert...

Indeed. I'd highly prefer this...

I do wonder, how many printing applications actually honor these tags...
