Several embodiments of an improved flexible prelaminate are disclosed, which share the following common characteristics: (1) the prelaminate cover sheet (24) has an overall thickness in the range of about 6-12 mils, of which the exposed layer of heat-activated adhesive (34) for bonding to the graphic, has a thickness in the range of about 2-4 mils, typically 3-4 mils; and/or (2) the bottom sheet (26) of the prelaminate has an overall thickness in the range of 6-12 mils, with the exposed heat activated adhesive layer (36) which will bond to the substrate of the graphic, having a thickness in the range of about 2-4 mils, preferably 3-4 mils. The overall thickness of the prelaminate can be increased substantially by the use of a sled in the form of a board or the like, on which the prelaminate with graphic is placed, to form an assembly which is passed through the rollers.
