[filmscanners] Re: Pixels and Prints

["Bob Frost" <bob@frost.name>]

Laurie,

I thought I had read somewhere that if you send images to the Epson driver
with dpi that are larger than its native dpi (360/720) it simply discards
rows of pixels as scanners often do, rather than downsample them by any
interpolation method.

I do concur with your conclusion; and in practice, do what you suggest. From
a theoretical point of view, I was just curious about the answer to the
question given that so many in the discussion were arguing that if one sent
the printer a file with less than its native resolution the printer would
perform an interpolation using nearest neighbor techniques which would lower
the quality of the output but did not mention the effect of the oposite case
where one sent a file that had a resoution higher than the printer's native
resolution.  Thus, leaving open the question as to which theoretically would
be the best option to take if one were to have a choice - e.g., letting the
printer upsample to its native resolution or downsample to its native
resolution.
