To make sure that the PDFs that you download from Rodeo have your own branding, you must upload a template. It is important that this is well laid out. Here you can read how this is done.
For all three documents, you have 415 pixels at the top for the header and 450 pixels at the bottom for the footer to add information to your own interpretation. You can upload this as a PDF in Rodeo. If you use more than this space here, it will overflow with the text.
Furthermore, it is important to remember that sometimes you have to fit the text to show it clearly on a document. Just like you sometimes insert a page break in Word to make the text extract legibly over the pages. A few well-placed blank lines can ensure that the text is displayed logically per page.
