[sane-devel] archiving old documents

[gobo]

hello,

for some time how, i've been storing documents using the following in scripts:

scanimage -x 215.9 -y 297 -pv --resolution=300 --mode=color -d
hpaio:... > file.png
convert -density 300 file.png file.ps
ps2pdf file.ps

the png and ps files are deleted.  this has resulted in a reasonable
compromise between storage requirements and the infrequent need to
print the document.

now i wish to archive some old family documents that date back beyond
1930.  most is text, but there are a few b&w photos in the mix.
storage space is not a concern.  my plans are to save the scanned
images, but also build a pdf for distribution by email.

those of you who have already made such archives, what formats and
resolutions have you found produce the best results should others
wish to touch up or make other uses of the images?


thanks.
