I include an RGBA image in a PDF and the text on that page appears dark, almost bold. The effect disappears after a page break. I convert the image to RGB and the text appears normal.
The effect is most noticeable with Text rendering set to LCD/Flat screen at 40-50% zoom, but it's there no matter what.
The effect does not show up using Sumatra, Multivalent or Apple Preview; only in Adobe Reader (9.1) or Acrobat 8.
I'm creating the pdfs with pdflatex; converting the graphic to RGB fixes the problem. This looks like a bug to me, but I'd like to understand why it's happening.
The attached file has 3 pages. The first page includes the RGB image, the second the RGBA image (text is darkened) and the third uses the RGB image again.
page2 has rgba image, darkened text. (195,065 bytes)
