I would like to add few points in the discussion. In a pack of 10 sheets we have
1) 10 sheets are ZINK Paper which is used for Printing. [ Sticky-Backed Photo Paper]
2) 1 Single sheet is Smart sheet .
The Smartsheet will pass through the HP Sprocket Photo Printer automatically before the first print job. The Smartsheet cleans and calibrates the printer for the paper pack. Use a Smartsheet with each pack of newly loaded paper for best print quality. Each Smartsheet is specially calibrated to prepare that pack of paper for use in your printer. Discard the sheet after you have printed all ten sheets in the pack.
