A ceramic transfer picture with a water-absorbing separable paper carrier is provided with a screening layer on its surface opposite the image layer. Said screening layer leaves uncovered only the image areas to be moistened; further, a compensating layer of polyglycol or polyethylglycol wax is provided at or in the image layer as well as an organic intermediate layer between the paper carrier and the image layer controlling the plasiticization of the image layer. In order to achieve a fast separation of the images from the paper carrier, steam is raised during the transfer of the decalcamia pictures. Owing to the nonabsorbent screening layer, the paper carrier is strong so that material in rolls may be used in a mechanical transfer. The applicator-apparatus for it has accordingly a transport device with a delivery spool for the lamellar decalcamania picture material and a batching roller for the separated paper carrier, driving, guiding and tension rollers as well as a movable, heatable pressing agent for the objects to be decorated, such as a stamping device, opposite a holder, e.g. a turning table.
A process for applying decalcamania pictures to an object of glass-or ceramics-type material which comprises providing a decalcamania picture comprising a water-absorbing carrier paper having on one surface a vitrifiable color image layer not extending over the entirety of the paper and an interface layer between said image layer and said paper to ease separation thereof, and on its other surface a substantially water-impervious screening layer which is intact only in those areas corresponding to those where no color image is present on the opposite side of the paper, positioning the picture on to the object with the screening layer on the outer side opposite said object, transferring the image layer to the object under the action of moisture applied from the opposite surface of said decalcamania picture from that bearing the color image layer, heat and pressure, and releasing the paper with said screening layer from the transferred image layer.
