- The Scanning FAQ should answer your question about what resolution to scan at
- and if a 600dpi HP Scanjet will do justice to a photograph (hint - the answer
- is yes in most cases). Your potential 600dpi printer will do a much better
- job at printing halftones than your 300dpi printer because of its ability to
- create more halftone (grey) steps, at 600 dpi and 75 lpi you can get a few
- more than 100 grey steps. 75lpi is about the maximum I would push 600dpi.
- Unfortunately 75lpi will appear fairly course (more like a newspaper image).
- This wouldn't be a problem for internal publications going to a photocopier,
- but you probably won't be happy with this printed to your offset press
- quality pieces. 600dpi will save you imagesetting cost on many of your text
- pages, but I think sending your photos to be imageset at at least 1200dpi
- 100lpi will make a better final page. FYI, if you want the full 256 grey
- steps from your 600dpi printer, you'll have to use an LPI of no more than 50,
- which is as course as your old 300dpi laser.

- Yep, I didn't proof-read. There are a number of faux pauxs, in fact much of
- my benchmark lists included some early pre-release units whose specs and
- features have changed a little now too.
-
- By the way, I'm glad you liked the Scanning FAQ, I debated about posting the
- whole thing to the LIST or just uploading it to the FTP area. Since there
- are a number of you that don't have FTP ability I thought this was the thing
- to do. I am planning to turn the FAQ into a much more polished resource and
- loading it to the FTP site later as a PageMaker document if there is enough
- interest. That way I can simply publish updates to the Q&A section and
- various addendums to the LIST and not waste the bandwidth with a 10 part
- update.
