Digital BW, The Print

Can someone post or direct me (WWW) to a resolution chart for 
printing?  What I want to know is what image resolutions and DPI are 
best for each sized print, 4X6, 5X7, 8X10, 11X14 and so on.  I know 
that there is a point in which everything else is overkill for a 
specific resolution and DPI. 

Thanks in advance,
Duncan

Duncan,

I don't know what you're asking.  What printer are you talking about?  What
workflow?

Typically, there is no "specific resolution and DPI" for printing B&W on an
inkjet printer...  The higher the resolution you send to the print driver,
the better your output will be.  This is true on the Piezo driver up to 720,
and on the Epson driver to, I believe, 480?  Print size makes no difference
either.

What I suggest is scan at optical resolution, and resize in PS but do NOT
decimate the image, which you can prevent by not checking one of the boxes
at the bottom of the resize window...it's obvious which one.  The PPI will
come out to some odd number, but just send that to the printer, and you
should get the best results you can.

I am talking about a Canon S9000 in both color and B&W and also best 
images for Fuji Frontier.  Workflow is Photoshop direct from a Canon 
D60 or a scan from a 35mm transparency (Velvia or Provia) at 4000dpi 
with SS4000.

Hi Austin:

At final print size, just have your file be from between 180ppi and 360ppi.   
180 would be for larger prints and up to 360 for smaller prints. Digital 
C-prints do fine from about 200-300PPI at final size.

All the best!

Duncan,

For a Fuji Frontier, there are different models, and the requirements are
different.  I'd suggest you speak with the operator and see what they
recommend.

I suggest scanning at full scanner optical resolution.  Then when you
downside, either D60 or scan use a stepped methodology, which has been
described here and should be able to be found in the archives.  It will
retain detail that a straight downsize would not.

Regards,

Austin

Duncan,

I'm not really helping but maybe clarifying so some else can.

Are we talking about the 'standard airforce resolution chart' like the one
referenced here...
http://www.displays.org.uk/DISNET/content/mtf.htm
not that it's downloadable.  Would be fun to have something like that in
with the page like was set up for the exchange here...

Just curious.
Cleavis

If that's what desired, this is a postscript description of the
Air Force resolution chart.   You can read it into Photoshop
and rasterize it for any size and resolution you like.

No I am not talking about system or lens resolution I am talking 
about file sizes.  What is considered the minimum file resolution and 
dpi to make a 5X7, 8X10 etc....

Thanks,
Duncan
