If the epub looks more like the ADE screen shots, then I can assume that it is the ReaderSoftware that has a rendering bug, and press on with my 16-shade pngs.

Thanks for checking for me.

Here is what I've found, though I've no idea why.

First let me say that I randomly selected an image from The Innocents Abroad - Blucher coming off his donkey - and found that that image rated 5 out of 5 on both Sony T1 and T2.

Then I checked your two images as below, with 5 being perfectly acceptable, 3 not acceptable, and 1 (if I'd seen a 1) being so poor I couldn't make out what the image was.

iPad/iBooks: 5+
Sony T2: 5
Sony T1: 3 - too fuzzy and speckled to be acceptable.
Kobo Touch: 3 - as above
Kindle Keyboard: 4.5 - I'd have used it, but it did not look as not as good as on the the Sony T2.

I have no idea why the appearance on the T1 was markedly poorer than on the T2. The T1 is older of course, but Blucher looked just as good on the T1 as on the T2.

If we were to collaborate again I'd prefer you sent greyscale jpgs, not images done the same way as these two.

I don't think I've seen a posting before in which the same images have been viewed on several different readers. Do you think this thread might fit better in the Workshop forum? It's not just a Sony problem.
