I'm working on production of the book and web site / CD for MW2007. Papers are on-line before the meeting, and in the hands of the delegates at registration. A big part of this is making screen-shots and line art work on-line and in print. Here's the process (for those of you whom I'm asking for 'better images').

For Screen Shots

Start with a screen grab at the maximum dimensions that maintain proportions (min. full screen @ 1024 x 768), but bigger IS better.

Set up matters. Remember to focus on your content; we don't need to reproduce all that browser stuff, or the blank space at the right.

The order in which you make these transforms matters.

For Web:
--> resize image to max. 400 wide @ 144 dpi
--> sharpen if necessary
--> save as .jpg (8 quality) -- or png if line art

For Print:
most are one-column wide
--> resize + 466 dpi (133 line screen)
--> change image mode to grayscale
--> resize to 2.688 in wide
--> sharpen if necessary
--> save as TIFF - lzw compresion ok

Other print sizes are [used sparingly]
3.66 in wide
5.875 in. wide

Needless to say, i have photoshop actions to do these...

For line art and diagrams

Web:

--> display the image on-screen at the size you want it to be on the web
--> do a screen grab

[if the quality isn't great, try twice as big and then resize the screen grab]

Print:

--> Create a print quality PDF (300dpi)
--> OR send a vector version of your file
--> OR send the original source file if you don't know what that means.

Printing an image of your box graph that's been submitted for the Web at 72 dpi just isn't an option.
