My personal experience has been that folks who don't work in industry or in a 
government agency which has a hazmat specialist on board have never heard of an 
MSDS. Wouldn't know what it meant if they had one. At BLM, we're required to 
take hazmat training once/year. It's especially critical here in Oregon and 
other states where meth labs and dumps are so prominent on public lands.

--- Begin Message --- File size is not a very good indication of whether the resolution of a photo file is good enough. You can easily change the file size by a factor of 10 by JPEG compression that makes no visible difference in the photograph and does not change the resolution.

The printer that I think the Texas Caver uses (I steered it to them) prints halftones at 150 DPI. The rule of thumb used to be that you wanted to start with 150% of that resolution, which would be 225 DPI. The printer asks for 300 for grayscale or color illustrations and 600 for black-and-white line copy such as cave maps. What I usually ask people to send for the Association for Mexican Cave Studies is photos that are at least 1200 pixels high or wide. The largest I usually print photos is 4.44 inches, so that is good enough, even when I do some cropping. If I want to use a photo on the cover, I go back and ask for more.

Actually, it takes a powerful magnifier to see a difference in the printed results, even if a map starts out at 300 DPI or a photo at 150. Where you really get in trouble is something that is just screen resolution. Beware of photo software with one-click methods for e- mailing or posting photos. Those typically automatically reduce the resolution (and file size) on the assumption that the result is to be viewed on-screen. E-mail the actual original photo file as an attachment. Even with the highest quality JPEG compression, it won't be bigger than 10 MB. (Do _not_ JPEG line copy such as cave maps. ZIP or LZW compression is OK. As there is no such thing as a black-and- white JPEG, this question doesn't arise, unless you've used grays or colors in the map.)

Jill, the printer's prepress people will fuss if illustrations are less than their recommended resolution or color illustrations are not CMYK. Save yourself an exchange of e-mails and include in the instructions with the PDF files something like "I know some illustrations are less than the recommended resolution. They are the best available. Don't worry about it. If I have forgotten to make a color photo CMYK, don't worry about that, either." There is, of course, no point in your upsampling (or downsampling) things just to keep them happy. You probably already know that you have to be careful making PDFs. Acrobat by default JPEG-compresses or downsamples things, unless you tell it not to.

Please don't send double digit files size photos. :)

As I was saying to Jim Evatt, contractors on fed jobs are required by law to 
have Material Safety Data Sheets (MSDSs) on the jobsite for all materials being 
used. All you have to do is ask to see them. Unfortunately most people know 
that. I only know it because we're required to take hazmat training yearly.
