You talk about using PNG and PDF - and then post two JPEG files.
How about posting the original PNG and PDFs, so that we can examine
the data in question. Otherwise, it's all guess work...

I use PNG all the time because it's the only one that provides
transparency colors properly.

Is a printer a viewer? Acrobat standard and pro have options for

Of course, I agree that iText passes images as they were given,
and pdf viewers use them as they are passed. But as the initial
poster said, there's a quality issue of rendered images in viewers!
I have to say that this problem can be more easily recognizable in
statistical charts and fonts draw
That's basically correct, until PDF vierwers are improved!
Viewers may never see original 100% images. So they will always
see blurred images.
Best tactic may be that see PDF files using 100%, and find
best quality image sizes for the spaces in your pdf documents.
Not much we can do other than

Yes, I experimented with that approach. But scaling results in some pixel
degradation and while the size is correct, the quality is still poor (wor

Scale the image (make it smaller) before inserting it in the PDF, this is
the same as increasing the dpi.

This is a PDF viewer problem, not doing proper image scaling that combines
with anti-aliasing. Images in PDF are generally poor. If you apply
higher-definition images, you would expect better quality showing. This is
not the case with PDF viewers!

Hello,
I am generating PDFs and am including JPEG images. They seem to always get
"blown up" larger than they should be and therefore look blurry and
unappealing. I am guessing here, but the problem seems to be that they are
being scaled to match a 72dpi default of some sort. In one case, my i
