> not intentionally doing anything that calls for transparency data.

Add +matte to remove any transparency from your image before you save it as
PDF.  If your document is predominately line-art you probably want a tool
that creates a vector-based rather than an image-based PDF.  Try iText for
example.  If you want an image-based PDF you might be able to optimize the
PDF by creating a colormapped PDF (use the -colors option).  Its likely that
ImageMagick is not the ideal tool for your particular task.
