Digital BW, The Print

Julian,

Just a thought. On my 1280's I am finding that I can minimize or get rid of
this type of what shall we call it, loupe level banding, linear artifacts,
by trying different image resolutions in the files sent to the printer. In
the end we may be doomed to live with this to some degree. If you really can
only see it with a loupe should you be worrying about it? Ultra picky has a
point of diminishing returns. I know. I'm an expert at driving myself crazy.
