All of my experience with Tiff compression has been with 1 bit data, and I have a couple things to add to Andrey's advice:

• Fax compression, particularily G4, works well with most 1 bit data, but it can perform horribly if the image has alot of small features that are seemingly randomly placed. Compression can take a very long time and the resulting file can be larger than the original.
• In general, I have not noticed that Deflate compresses any better than LZW, nor that it works much slower for 1 bit data. I became a fan of Deflate when Unisys started flexing its patent muscles. I use it whenever possible because it behaves well with all the 1 bit images I have used it with.
