Abstract: Transfer materials are described which are of particular value in sign making applications. The materials consist of a carrier sheet, indicia thereon, usually formed by printing from a printing ink composition and adhesive over the indicia. The dry transfer material may be used in the usual way to assemble a desired legend on a temporary carrier sheet using the pulling power of the adhesive optionally assisted by the "stretch release" technique if the carrier sheet and indicia are appropriately formulated. According to the invention, the indicia are formulated so that following their transfer to build up the desired legend, they may be adhered under the action of heat and pressure without plastic deformation to the surface of a transparent or translucent rigid sign sheet made of polymethylmethacrylate, polyvinylchloride or cellulose triacetate.
Abstract: A drawing board device is described of particular value in composing signs using dry transfer lettering sheets. The board has a base and a horizontal rule mounted thereon and capable of moving vertically and horizontally. The rule has one or more magnetic clamps for sheets of transfer material, and one or more sets of register pins for registering with e.g. a preprinted line on or preprinted holes in the sheet. The vertical movement of the rules is preferably stepped, the interline spacing between the lines of letters on the sheet being an integral multiple of the step length.
