FORMAT ORIENTATION The orientation of the pages of the PDF must match the choice made in your order (horizontal or vertical). Both pages must have the same orientation. Once you have saved the PDF file, ensure you do not rotate the pages using Acrobat. PLEASE NOTE: For double-sided printing, the sheet is rotated around its vertical axis, as if turning the pages of a book: bear this in mind when positioning the text, as well as following the orientation chosen in your order.
