2-color file open in Adobe Acrobat with Output Preview window open

For long and text heavy documents, it is easiest to design in Adobe InDesign with "Spot Color" swatches. That way your customers can send a single (multi-color) PDF for the document, without worrying about layers or export, and you the print shop can export the individual separations using Adobe Acrobat & Distiller. The generated files from this process are normal PDFs which can be used with any Riso or other machine.
