Just have a look at the following method of PdfWriter:

http://api.itextpdf.com/itext/com/itextpdf/text/pdf/PdfWriter.html#setPageEmpty(boolean)

Should work like so:

Document doc = new Document();
PdfWriter pdfWriter
        = PdfWriter.getInstance(document, new FileOutputStream("file.pdf"));
pdfWriter.setPageEmpty(false);
doc.newPage();
doc.close();

You tell the writer that the page is not empty, even though it is, so a new page will be created.

After you use, document.newPage();, it will be ignored if you don't add any content. So, if you need blank page, then add writer.setPageEmpty(false); right after calling newPage().
