Grey box behind the text visible only after print

Hello,

Recently i started to have quite anyoing problem. I use same print settings for few years and i never come across that isue before.

So, whenever i print artwork proofs sended from printing company i start to get grey boxes behind the certain part of the text. This grey area is not visible on PDF view. I need as accurate print as i can get, so this grey box disqualified the printout and now i cannot approve any artwork. 

I already use few otions:

Print as image - that remove grey box issue, but also drastically change colours and make text quality low. 

Print from Chrome - removes grey box, but change the picture size (Need to be actual size). 

Edit->Preferencies->Page Display - i played with this options and already printed dozens of pages with different colours intensivity but all with grey box.

I tried other computers and printers - same issue.

Only computers from marketing department which have Adobe Reader PRO manage to print document without any issues.

I'm using Adobe Acrobat Reader DC (64-bit).

On document properties i get some informations:

PDF Producer: Esko automation engine pdf normalize 18.0.1

PDF Version: 1.6 (Acrobat 7.x)
