That is really odd.
The proof pdf might be low quality from most providers, but text should still be sharp. It sounds like at some step, BookWrite or Blurb is rasterizing the pages and rendering as images?
Embedding the font should just embed the actual font, and not have the pdf rendered in this way.
Right I heard back from them (delayed as I was overseas).
They said
"...
I do not think this font was designed to be used in a printed book. And there is not a fix I can recommend that does not include still using this font.
BookWright will display almost any font that is installed on your computer. But the program is unable to check if a font is viable for print. Using a different 'standard' font will most likely print as expected. But if you are looking for a font specifically to help dyslexics, I would recommend looking for more options that are designed to be used in printed books."
So unfortunately I have no option but to use a friendly-ish standard font. Shame but it can't be helped I guess, even though their wording is somewhat vague at best!I suppose at least they gave me a credit for the printed book that was unreadable.
Your work is still marvellous though - and I can see it has made a difference for those applications that are display, rather than printed, so well done you.
