Watermarked pdf blocking the content

[loks07]

Hello all, I am trying to read a watermarked pdf which I am perfectly able to read it on my laptop running windows, with the watermark clearly transparent almost to the point of invisible. However it is exactly the opposite on my
Samsung 10.1 tablet with the watermark actually so dark that it is actually blocking the content of pdf itself. I am attaching the screenshot.

I have tried Quickoffice Pro HD, Adobe reader, qpdf viewer, apv pdf viewer, and also the inbuilt ebooks and kindle apps. But I must confess I have only tried the free apps. Can anyone please recommend any other app that may solve this problem and also can handle large pdf files with ease.

Thanks.
