PDF art work files for Commercial Print

I have ensured I have specified the Pantone spot colours and also the die cut and fold lines with a spot colour.  I have also included in the description details of stock, special finishing and the colours. 


As a separate issue because the hexagon shape and the bag are both two stocks I spoke to Mike about how I specify this on a PDF.  In reality I would discuss with the printer to find out how he would prefer to be sent the information.  For the PDF submission I  created two art boards, one for each stock so that the PDF has two pages which are clearly described in the PDF details.
