摘要： A thermoforming method and apparatus is provided for a flat thin sheet plastic substrate having printed material thereon in the form of a matrix of a plurality of items. The substrate is clamped between a pair of clamp plates providing support for the substrate around the perimeter thereof and also in a matrix support pattern having a plurality of subperimeters providing individual support around the respective perimeter of each item. The assembly is heated, and then thermoformed into a contoured three dimensional workpiece by pushing a matrix of a plurality of tool faces into the substrate at respective items. The matrix support pattern of the clamp plates along the plurality of subperimeters prevents sagging across the substrate during heating, and isolates the items from each other during deformation of the substrate by the tool faces.
