If you need to enlarge the file, export the TIFF file the usual way (it will
be "postage-stamp" size, as you describe it: one pixel per grid location).
Then open it in Photoshop. Go to Image -> Image Size: choose "Nearest
Neighbor" in the "Resample Image" pull-down menu, set your width as desired,
leave the resolution at 72ppi, then click OK. Your image will be enlarged
with no antialiasing. Each of the patches will carry exactly its original
value, with perfectly sharp edges.
A better way (it keeps the file size smaller and rules out any
possibility of interpolation issues) is to go into Image Size,
UNCHECK Resample Image, and set the resolution to, say, 8 ppi.
