Yes I gathered as much. Could you elucidate how to achieve it using
QGIS? This is something like Layer Effects Outer Glow in Photoshop...

I want the whole of India to be covered in an A4 size page with 1 inch
margin all around. I suppose this is zoomed-out enough! :-)

Please try the attached images to demonstrate the problem with the
plain cbhypso images. They were produced by the ImageMagick convert
utility resizing to 6.25% and converting to JPEG (and then cropped to
-crop 90x120+632+98 to pass the size limitation for posts). I'm sure
if you try even with Photoshop or with output as TIFF the result will
be the same. You see that the water separation between various land
bodies is missing in the plain cbhypso images.
