Public bug reported:
Certain images are substantially degraded when printing.
The problem only occurs with Acrobat Reader on Ubuntu,
not xpdf or Acrobat Reader on Windows 7 (using the same printer and input PDF).
So there is something wrong with Acrobat Reader on Ubuntu specifically (or
maybe any Linux).
The printed image appears darkened or the available grey-scale
resolution is lesssened. The test image (attached) is blueish and the
printing was on a monochrome laser printer (hp3030), so the problem
might be related to mapping colors to greyscale.
The PDF was created by exporting from Libre Office Writer with PDF/A and
"Lossless" image compression.
Here are the exact versions of Acrobat Reader I tested:
Windows 7 (32-bit): Acrobat Reader 9.5.0 [works]
Ubuntu (both 64-bit & 32-bit): Acrobat Reader "9.5.1 03/07/2012" [image
degraded when printed]
Attached is a test file.
