Why is there a Smile logo on my PDF when I save it?
Documents saved by the PDFpen demo have the Smile watermark. The watermark will also appear on any printed documents. The only way to remove the watermark is to purchase a license for PDFpen and register the application. If you have already purchased PDFpen or PDFpenPro, make sure to register with your new license.
When you open a watermarked document with a registered copy of PDFpen, the watermark will be removed automatically. Save the document to permanently remove it.
Please do not save watermarked documents using File > Print > PDF > Save as PDF... or the watermark will remain permanently as though you'd printed to a physical printer. This embeds the watermark into your document, and registering will not remove it.
