PDF - from white to grey background

[mnvwvnm]

Hi forum,

After the last macOS update (sierra 10.12.2) I noticed a strange thing ((among others already known)...
I have a lot of scanned documents attached on my library. I work with Abbyy Finereader on windows system (Parallels): scan, clean, organize and ocred... Using this software on windows version allows me to control the results...
Well, so far nothing new. But, after the last system update, all the documents/pages scanned on grayscale (not b/w) changed the background color: from white to grey background!!!

On Bookends preview, Devonthink, Preview, Quicklook, Pdf Expert, Skim, etc... this is the new behavior!!! All my documents with pages scanned on grayscale are now more darker with the background on grey!
But on Acrobat all pages appears like before: white background!!!
Let me guess: another PdfKit issue?
Anyone with this NEW problem?

Thanks.

Sierra 10.12.2 broke all sorts of PDFKit features. This has affected many applications (including EndNote, DEVONthink, Skim, etc.). We're all looking for workarounds and waiting for Apple to address the many bug reports that have been submitted. We have an announcement urging Bookends users to avoid 10.2.2.
