QTR-Quadtone RIP

Hi Zissimos,

You should not have to convert the image in Photoshop - I have 
gotten great results by just saving the image as a tiff file in 
Photoshop. Other settings don't seem to matter much - 8-bit and 16-
bit, "Real" greyscale and "RGB" greyscale (where R=G=B) work equally 
well.

I have not encountered the same problem as you are experiencing, 
though admittedly the smallest paper I've used is Letter size, which 
I understand is a bit larger than A5. - Are you using a PC or Mac? 
Which version of QTR are you using?

-Matt
