- In my experience *all* 72dpi grayscale drawings are turned into b/w
- 72dpi rasters. I print greyscale images with the following circuitous
- (sp?) route:
-
- 1. Copy the greyscale image into GIFConverter (handy program!).
- 2. Set the resolution to 288 dpi
- 3. Select Greyscale (as opposed the the default--Color) I forget which
- menu.
- 4. Select "One Bit" display. This "dithers" the picture, turning it
- into a 288dpi b/w bitmap.
- 5. Print it, selecting "Precision Bitmap Alignment", or copy to a program
- like Claris CAD which can squeeze the image down until its 300 dpi.
- The resulting object can be pasted into MS Word, etc.
-
- If there's a simpler way, I'd love to hear it, but I will groan,
- because I pasted a lot of pictures into my dissertation this way.
