Text added to PDF appearing bold/rough

I'm adding/replacing some page numbers on an existing PDF's contents page, but the text is coming out bold, or rough. It's not right any ways, and I can't seem to fix it!

This is what I mean:

The numbers on the right are the existing page numbers I am replacing and the text is fine. The numbers on the left are the page numbers I have added using iText in Java.

Here is the code:

private static void fixTOCPageNumbers(int i, PdfContentByte content, List<Section> sections)
        throws DocumentException, IOException {

    int xPositionRec;
    int yPositionRec;
    int xPositionText;
    int yPositionText;
    int xOffset = 0;
    int yOffset = 0;

    content.saveState();
    content.setColorStroke(new Color(77,77,77));

    content.beginText();
    content.setFontAndSize(BaseFont.createFont("fonts/LTe50327.ttf", BaseFont.IDENTITY_H, BaseFont.EMBEDDED), 10f);

    int count = 5;

    for(int j = 4; j <= sections.size() - 2; j++)
    {           
        int startPageIndex = sections.get(j).GetStartPageIndex();
        int endPageIndex = sections.get(j).GetEndPageIndex();

        xPositionRec = 281;
        yPositionRec = 385;
        xPositionText = 266;
        yPositionText = 386;

        if(j > 6)
        {
            yPositionRec = 195;
            yPositionText = 196;
        }

        for(int k = startPageIndex; k <= endPageIndex; k++)
        {               
            content.rectangle(xPositionRec+xOffset,yPositionRec-yOffset,12,12);
            content.setRGBColorFill(255,255,255);
            content.showTextAligned(PdfContentByte.ALIGN_CENTER, String.format("%d", count), xPositionText+xOffset, yPositionText-yOffset, 0);
            content.setRGBColorFill(77,77,77);
            //content.fillStroke();
            yOffset += 18;

            count++;
        }

        yOffset = 0;

        if(j > 6)
        {
            xOffset += 229;
        }
        else if(j == 6)
        {
            xOffset = 0;
        }
        else
        {
            xOffset += 230;
        }
    }

    xOffset = 0;
    yOffset = 0;

    content.restoreState();
    content.endText();
}

Am I doing something wrong? This is the first time I've used iText and the code base wasn't originally mine.

Any help would be much appreciated!

You can simulate bold for example like this:

C#

cb.BeginText();
cb.SetFontAndSize(font, 11F);

cb.SetCharacterSpacing(1F);
// Fill color (stroke fill)
cb.SetRGBColorFill(0, 0, 0);  
cb.SetLineWidth(0.5F);
// Fill stroke simulate bold
cb.SetTextRenderingMode(PdfContentByte.TEXT_RENDER_MODE_FILL_STROKE);

cb.SetTextMatrix(x, pageSize.Height - y);
cb.ShowTextAligned(PdfContentByte.ALIGN_CENTER, s, (pageSize.Width / 2F), pageSize.Height - y, 0);

cb.EndText();
