Abstract
Methods and apparatuses for roll coating are provided. The roll coating system () includes a coating roll () having a deformable inner layer () with a surface thereof covered by a deformable outer layer (), the inner layer being softer than the outer layer. A substrate () is conveyed to the nip () between the coating roll and a back-up roll (). A metered coating material is transferred from the coating roll to a patterned surface structure () of the substrate at the nip to form a conformal coating on the patterned structure of the substrate.
