Material Safety Data Sheet
Unbleached paper in its natural form - brown in color.
A printing method in which ink is transferred from a plate to a smooth rubber "blanket" roller that transfers the image to paper (or paperboard). This method of printing utilizes printing plates rather than silk screens to transfer the ink to the containers. Offset printing is more exact than silk screening, and is practical for multiple color labeling. Offset printing is utilized primarily on round containers. Because plates are engraved for each color rather than making screens, offset is more expensive than silk screening. The process involves transferring ink from a printing plate to a rubber blanket and subsequently to the sheet (surface to be decorated).
