High quality images

[Dov Isaacs]

I must strongly disagree with ANY advice to resample
screen shots at any stage of the workflow prior to the RIP.
Although this might not be intuitive, upsampling a screen
shot in Photoshop (or name whatever tool you like) prior to
importing or placing into FrameMaker (or name your favorite
layout program) can indeed lead to lossiness. Despite what
many print service providers will tell you, all images
are resampled at the RIP (whether downsampled or upsampled)
to match the combination of the device's actual resolution
and the screening algorithms in use. And such resampling is
typically of quality comparable to the best you can do in
Photoshop. Since resampling is done at the RIP anyway,
doing a "manual" upsampling prior to the RIP process may
cause real content in your image to be lost. For screen shots,
such data lossiness can yield really crufty results. And
such extra resampling prior to the RIP process violates the
"reliable PDF workflow" principles.
