PDF XChange Forum

Hi,

when I convert a Office document whith an embedded png-graphic with transparent backround, the converted PDF file looks correctly in print preview, but has a black backround instead of the transparency when printing the file. When I use Office 2007- or Adobe to convert the printout is correctly.

I have attached a sample file and the original PNG-file

Best regards,

Hello MFd,

I see that you used build 195 of our products to create this sample file.
Please download and install the latest build:

And let us know if the problem persists.

Hello Stefan,

unfortunately the problem still exists.
see Att.

Best regards

Thanks for trying with the latest version MFdCDrMA,

Could you please also provide us with a copy of the file created with e.g. Adobe's distiller for comparison?

And does selecting "Print as image" inside the Viewer's print dialogue help with the output - as it seems you didn't mention that in your previous post?

Best,
Stefan

Hello,

"Printing as Image" does not produce the black backgound, but this is not a good way because of the loss of quality.

The attached file was produced with Amyuni PDF Konverter 2.1. It does not have the "black box"

When I print the file converted with PDF-XChange on an old PCL5 driver, ist also looks fine.

I have tested with several drivers / Printers --> Result:
Kyocera KM-C25E (KPDL) / Kyocera KM-C2525E --> black
HP Universial Printing PS (V5.3) / HP Laserjet CP3525 dn --> black
Lexmark Universial PS 3 / Lexmark X945c-- > grey
Lexmark Universal XL / Lexmark X945c --> grey

Windows XP/Office 2003 -- Windows XP/Office 2007
Windows 7/Office 2003 -- Windows 7/Office 2007

Thanks MFd,

The second file prints correctly - because the converter you used actually made the image not transparent - and the one our drivers created is still properly transparent. See the attached image.

I am afraid that for now we can not offer any better solution than the "Print as images" - and if you change your printers settings to print images with 300 or 600 DPI - the quality loss should not be too visible.

We are working on a totally different printing routines for v3 of the Viewer - and then "print as images" should no longer be needed - but this new version will be released on 31 May 2012.
