Re: [PRODIG] Interpolation

[Richard Lewisohn]

I would have thought that a more relevant 'real world' test would be to 
see if it is better to 'upres' a 31MB 1Ds file so that it prints at 
30"x40" at 360dpi, or NOT to upres the file (as much or at all) and 
print at 180dpi.

In my (albeit limited) experience, the results have been better 
printing a file with minimal increase to the size of the file at 240dip 
or 180dpi than when 'blowing up' the image using stair interpolation to 
the 'correct' size to allow it to be printed at 360dpi.

Surely any gain in image quality due to printing at 360dpi will be lost 
in 'upresing' the original file.

Hope this made sense without having to read it five times!
