yellow light around all black pixels with blendmode darken Acrobat Pro DC

Report · Dec 19, 2019

Hi everyone,

Acrobat Pro DC is displaying all of the elements which use "blendmode darken" with some yellow light around black. Printscreen attached. All other thirdparty PDF viewers are showing such documents correctly, in black and white.

What can I do about it?

Thank you very much in advance,

Yuliana

This is a behaviour with all PDF files of a specifik sort - which uses "blendmode darken". I have a lot of different files with this issue, I can send you one of them.

Try to recreate the file, open the file with web browser. Right Click on the PDF > Open with Google Chrome and download the file and save as with different file name and check.
I have done all of the above, it does not help. And, as I already have said, all other thirdparty PDF viewers show such files without any problems, this yellow effect comes only with Acrobat.
Thank you very much for you help, Yuliana

Hi,

the new version shows the same error. I did not find the way to attach a PDF to the private

message. Only photos and videos. How do I do this?

Thank you in advance,

Hi Amal,

I am creating PDF using PDFLib library (https://www.pdflib.com/). As soon as there are "layers"

on the page (text over the image etc.) and I use blendmode "darken" - to achieve the "transparency"

for black pixel underneath the white ones - I get this yellow light around all elements which lay in the intersection of rectangles with different content. You can see it for yourself - part of the text is yellow and part is not and this is exactly where the text intersects with overlayed white rectangles.

I do not have complex transparency in my documents - the only necessity is that sometimes black must be seen through white, and I was told by PDFLib to use "blendmode darken" for that.

I do not have any plugins nor any security software. Moreover, I have tried to open such PDFs on several different computers with different Acrobats (I think they were even different versions, not all of them Acrobat DC), and the yellow light is always there.

So this is definitely not a matter of my settings, but looks like persistent problem to me.

I would be very grateful if you could help me further with this problem.

If you need further examples of similar problematic documents, please tell me.

Thank you very much,

Yuliana
