As I said the problem in your book is that kind of cyan used for text. And, as I just posted, according to me the best solution is for Ectaco to write a PDF/ePUB/DJVU viewer where user can adjust contrast and/or convert into B/W.

Since we have not this hypothetical feature yet (maybe never) I provide to convert the document in B/W and I also crop for best zoom fit-to-page:

P.s.: generating the B/W version is easy in windows with Acrobat. But I use linux and free software so I just do:

Code:

pdf2ps original.pdf o.ps
ps2pdf -sColorConversionStrategy=Gray -dProcessColorModel=/DeviceGray \
          o.ps original-bw.pdf
pdfshuffler original-bw.pdf ;# output to "original-bw_cropped.pdf"

The results are:
original-bw.pdf
original-bw_cropped.pdf

@Valentinka: try the BW cropped version on your JBC and on your kindle too. Kindle surely will look better white background, but resolution are maybe could surprise us.
