Abstract
Images are impressed on the surface of plastic tiles by a sublimation process. A tile having top and bottom surfaces is placed in a heating press having top and bottom platens. A transfer medium with a printed image thereon is placed in contact with the top surface of the tile. The tile is heated to a temperature sufficient to sublimate the dye and transfer the image onto the top surface of the tile. Heat is applied from both the top and bottom of the tile to prevent warping of the tile. The heat applied to the bottom of the tile is preferably slightly greater than the heat applied to the top of the tile.
Claims6
A method for making a plastic tile with a superimposed image on a surface thereof, comprising:
- a) forming a top member with a generally planar surface and a support member;
- b) contacting the planar surface of the top member with a transfer medium impregnated with sublimation dyes;
- c) heating the top member and transfer medium to sublimate the dye on the transfer medium;
- d) maintaining the transfer medium in contact with the top member while the top member is heated so that the sublimated dyes penetrate the top member to form an image on the planar surface of the top member;
- and
- e) joining the top member to the support member after said image is transferred to said top member to form a tile.
