I have the PDF file having watermark on it.It looks like follows:

I want to remove the watermark from the PDF file using python. I have tested existed solution on internet such as using PyPDF4.But that doesn't works for me. What I want to do is remove watermark and the apply some extraction task on PDF. My extraction task is to get the tabular data from PDF. For that purpose I am using camelot-py.Here, We shouldn't convert PDF to images and back to PDF because we couldn't extract the contents in PDF using pdf readers like camelot-py or tabula. PDF file is attached here.
Thank you!
