Abstract
Abstract 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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
151 words
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.
Claim 2
Dependent Claim
151 words
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.
Claim 3
Dependent Claim
45 words
A process according to claim 1, wherein said decalcamania picture employed is one wherein the screening layer is present in the form of a lattice, grating or line pattern in areas corresponding to those wherein a color image layer is present on the opposite surface.
Claim 4
Dependent Claim
23 words
A process according to either of claims 1 and 2, wherein the pictures are moistened prior to the application of heat and pressure.
Claim 5
Dependent Claim
23 words
A process according to either of claims 1 and 2, wherein the pictures are moistened and heated simultaneously with the application of pressure.
Claim 6
Dependent Claim
19 words
A process according to either of claims 1 and 2 wherein said moisture and heat is provided by steam.
Claim 7
Dependent Claim
38 words
A process according to claim 1, wherein the decalcamania picture employed has a further layer superimposed on said color image layer of material which can be converted into a flowable state by the application of heat or moisture.
Claim 8
Dependent Claim
22 words
A process according to claim 6, wherein the object to be treated is slightly preheated for additional activation of said further layer.
Claim 9
Dependent Claim
18 words
A process according to claim 6, wherein a pre-moistening is effected for additional activation of said further layer.
Claim 10
Dependent Claim
56 words
A process for according to claim 1 wherein plasticization of the image layer during transfer to an object is controlled by an intermediate control layer provided between said image layer and said interface layer, said intermediate control layer being composed of a material which will burn without leaving a residue during later firing of the image.
Claim 11
Dependent Claim
33 words
A process according to claim 1 wherein said decalcamania picture forms part of a strip comprising a plurality of said decalcamania pictures and each picture is applied individually to a glass-or ceramics-type object.
Claim 12
Dependent Claim
57 words
A process according to claim 10 wherein said strip of pictures is moved past a pressure means at a rate synchronous with that at which glass-or ceramics-type objects are moved past said pressure means and said pressure means is employed to transfer a color image on to each glass-or ceramics-type object as it passes said pressure means.
