Any way to get LZW compression on figure outputs to a tiff?

I am saving a sequence of tiff files using print(gcf,'name','-dtiff')
The files that are output are compressed (compared to -dtiffn), but not nearly as much as could be done with LZW or similar: dtiffn: 5.8MB dtiff: 2.8MB LZW (external): 0.2MB
I know there is an LZW option for imwrite, but I'm trying to print figures. Any suggestions?
Thanks

I am not certain here: are you asking to run LZW on the generated .tiff file, or are you asking that the .tiff file use LZW as its internal compression?

I guess it's moot after trying the PNG format. It's the smallest file of all. Thx

Don't bother. I don't know anyone who uses that anymore. Not many used it even before, when the patent was in force (patent has since expired). You should use PNG format now. Also, see export_fig ( http://www.mathworks.com/matlabcentral/fileexchange/ to save figures as images.

Yes, PNG is very good, however, some journals require figures to be submitted as TIFFs with LZW compression, any ideas?

After you have saved the image to a tiff one way, you can go back and imread() the tiff and then write it out again using the 'compression', 'lzw' option.
