We have a block that we put on unapproved drawings that says "Preliminary - Not for Production". It's an annoying block because it's kind of clumsy and takes up valuable real estate on the drawing. So I thought it would be a good idea to create the same thing with a watermark instead. The checker is now telling me that when he does his checks, he prints the SW drawing file to a .pdf file and OCR is picking up the watermark letters and highlights or marks those up instead of the drawing dimensions. Does anyone know a way around this?
