Plain White Cards
Plain White Cards are sealed with a clear, impervious topcoat so there is no absorption of applied coatings into the paper. The paper used for Plain White Cards is thicker than regular chart paper(20 mils versus 14 mils) to give greater rigidity for more convenient handling. Although designed for informal, hand-held brushout applications, they are also used for making drawdowns and colorimetric measurements. Plain White Cards are available in a variety of standard sizes and special sizes are available upon request.
