There are ones available in Japan that have a heat transfer of around
6 or above:

I only get blank pages for these Excite pages. Is there a trick to seeing
the real page ?

This one is fine, albeit in Japanese. We had an older model in a place I

heat. Certainly didn't manage 6:1 but I'll investigate further.
