Sorry for the confusion. Allow me to clarify this.

In the resulting image, now 200 kbytes, every 150 pixels
correspond to one inch of the printed page, from which it was
originally scanned. Thus, I'm using the shorthand terminology
that this is now a 150 dpi image. Since most computer screens
have a resolution in the rage 100-120 dpi, this means the image is
displayed a little "larger than life".
Ah ok, now I understand what you are trying to do.
TIFF G4 seems actually the best format for these kind of images,
regardless of the dpi setting. PNG can store 1 bit images, but even at
the maximum compression level (9) the full 3616x5550 image is about
380 kbytes instead of 200.
