Abstract
A method for transferring a hot-melt transparent protective material comprising steps of; contacting an ink sheet on which one or more color hot-melt ink layers have been provided with a moving recording medium, pressing and heating a thermal head system having an array of heat elements from above the ink sheet to print desired information, contacting a protective material sheet on which a hot-melt transparent protective material layer has been provided, with a printed surface of the recording medium, and pressing and heating the thermal head system from above the protective material sheet to transfer the hot-melt transparent protective material onto a surface of the picture and to apply thereon an overcoat of the hot-melt transparent protective material having a specific pattern.
