iText doesn't change colors. If it prints blue, then the image has blue or the printing process has some flaw. Other possiblity is the PNG only having black and gray but be coded as an RGB. The printing process sees an RGB image and disregards that it only has BW.

Subject: [iText-questions] Images: color problems
Hi all,
I have been trying to embed a black and white PNG image into a PDF
document, but for some reason this image seems to change color once
embedded.
The image is pitch black, with some grayscale in the antialiasing. When
it is printed from the PDF, using both xpdf or Acrobat 6, the resultant
image is blue-gray in color, but not pitch black like the original PNG.
This is causing problems for us, because it's coming out as a "colour
print" out of the printer, which we get charged for per colour copy.
Does anyone know how to tag an image as black and white only?
Regards,
Graham
