C1S and C2S Board Stocks are engineered to meet the full spectrum of print performance needs, from everyday production to the most demanding applications. Our portfolio is anchored by two distinct tiers—Standard Boards that deliver consistent, cost-effective reliability for high-volume work, and Premium Boards designed with advanced coatings for HP Indigo to provide superior print quality, durability, and finishing performance. Together, they give printers the flexibility to match substrate performance to application demands without compromise.
