Digital BW, The Print

Barry, you might try enlarging to 20x20 with GF and then printing, say a
12x12  portion of it on your 1280.  You should be able to judge if the
quality is then acceptable before spending money for a lab print.  If your
final output size is 360, then you have 360x20=7200 for the big print,
starting with 1600 for the scan.  I use GF with success for smaller
increments.  I would be surprised if the 20x20 works out, but you never
know.

Regards,

The other thing is don't forget that digital printers print at 225 or 240
dpi so you have an increase in size straight  away. Also they print RGB
files so you need to make sure that you convert to RGB in a way that doesn't
introduce colour casts. My lambda lab publishes its profiles so if you have
a profile for your printer you can print through both and check for colour
casts.

the DPI you are giving are not exactly bindin. My printer can (and does)
output at 400 DPI for critical detail. they also provide on-the-fly
enlargements, as the machine uses it's own proprietory upsampling which was
specifically designed for photographic output.

now to the original question. you say that the scan was 2 1/4 x 2 1/4 @ 1600
dpi. that should give you a file of 3600x3600 pixels without any
interpolation. if the image quality, detail, sharpness is great inspected at
100% magnification you can easily print this image after interpolation at
20x20". try interpolating to 30x30, sharpen moderately, add some gaussian
noise, resize down, print.

i generally send my files to the lab at 300 dpi, unless i want some
small-format with rich detail, then it is 400 dpi. as for the choice between
durst and kodak - no lab i know would not make you a small test print at no
or very moderate fee, so you can judge the output ...

cheers

Thanks for the extra info - the place I use always insists on a 225 -ish
file! I'll check if they accept more. What machine are you using?
