Re: filmscanners: ReSize, ReSample or ReScan ?

Shough,

Just how is this chart/print supposed to be interpreted? At first I thought
all resolutions printed well on my Epson1160 with MIS VM quadtone inks. Then
I noticed that there are heavy lines scattered about within each resolution
target, but then I looked at the PDF, and they are there too. However, as I
change the view magnification in acrobat, their location shifts. As some of
this appears to be either an optical illusion, or an effect that occurs
within the monitor or the path to the monitor, I have no idea how closely my
print should match my screen view in this regard.

If I am just looking for the little line slashes to print without jaggies
(aliasing) then I'd say, on my setup, all targets print excellent.

If I remember correctly, it was Jack Phelps (sp?) of Applied Science
