Abstract
The invention relates to methods and apparatus useful for making color filters for liquid crystal display panels. A multicolored ink pattern is deposited to a substrate while in a deformable state, flattened during the deposition process, and the deformed, more uniform shape of the printed dot is thereafter retained, preferably by curing during deposition. The transfer layer is preferably formed on a collector roll. A plurality of colored ink patterns is then transferred to the collector roll, preferably from a single pattern roll having multiple patterns thereon, to form the multicolor image that will become the color filter. This multicolored image is then transferred to the substrate.
