Stop printing non-bold text in bold from PDF file

Question

Despite everything, this problem is still occurring so I have re-opened the question. Even with:

\pdfpageattr {/Group << /S /Transparency /I true /CS /DeviceRGB>>}

Appended to the preamble of the MWE, I still get bold text printing where it should not be.

Can anyone advise?

Everything posted below from the original question remain valid:

When I print pages of a PDF generated from a LaTeX document, non-bold text is sometimes printed in bold. There doesn't appear to be a pattern to this but the bold text does seem to be apparent around the pages which have graphics embedded in them.

My document is generated from PDFLaTeX using MikTex 2.9 via WinEdt 9.

I know that this issue has been raised in one form or another in other posts and I write with reference to this page

As there are rather a lot of PNG files in this document, can anyone tell me if this can be solved by simply removing transparency from my the PNG files? Or do I need to remove transparency from these graphics, or add the following line before every graphic:

\pdfpageattr {/Group << /S /Transparency /I true /CS /DeviceRGB>>} 

This is the sort of thing I mean where the bold which should not be bold is underlined.

    A typical visualisation includes two charts: 

    \begin{enumerate}
      \item An aggregation displaying the frequencies of keyword updates since polling began. The chart type is the one defined by the user for a sample visualisation (Section 1.4.1) prior to a new set of mining rules being persisted to the database.
      \item A time-series (Chapter ??, Section ??) plot depicts keyword frequency fluctuations during the period of the aggregation.
    \end{enumerate}
