A sealing-enhancing coating for a gasket or a portion of a gasket includes flaky particles of chemically exfoliated vermiculite, at least 90% by weight of the particles having a thickness of no more than 30 microns, and no dimension greater than 1 mm. The invention is shown to include a print head operative in response to a print signal and a controller, electrically connected to the print head, for generating the necessary print signal. Said strip can be pivoted on the plane of the base section and is coupled to the carrier section. Using the comparison metric, a corrected set of gamut remapped colors is generated. Thus, the material has high polymerizability at the time of a chain reaction, so that a polymer having an increased mechanical strength and a high solvent resistance is produced.
