Think of the information being printed as if it were in layers, rather like a sandwich.
You can get something similar with PDF watermarks. If you think of a banknote, some watermarks seem inside the paper whilst others are on top.
PDF watermarking may use many of the subtleties of the physical world. Watermarks are added as a layer to the PDF document (which is why they are easy to add) and can be made to appear on top of or behind existing document content. Text watermarks may be static (always remain the same) for example “This document is the property of ABC Corp.”, or dynamic (changes depending on who opens the document, the date/time and device) for example “This document was viewed by Joe Bloggs on ”. a user has taken a photograph of a viewed document or a scanned in and distributed a printed one).Ī watermarked PDF is a PDF document that has a text and/or image watermark added to it which is displayed when the document is viewed and/or printed. However, the main use of watermarks is the ability to identify a user if a document is being distributed unlawfully (e.g. As well as text you can also add an image watermark to your documents.If your document or ebook consists of a cover page then you may want to check the ‘Don’t add watermark on first page’ checkbox so the visual effect is not spoilt by a watermark overlay.Displaying watermarks behind PDF content is less unobtrusive to the user yet still enables the document owner to clearly identify who the document originated from if it is unlawfully distributed. You can change the font, opacity, where the watermark is placed on the page (position), and whether the watermark is displayed on top of or behind PDF content.These variables will be replaced with actual data when the document is viewed/printed.
