First claim

The invention claimed is:

1. A method for producing a decal with at least one decoration comprising:
providing a water transfer paper,
providing a stamping film, the stamping film having a carrier ply and a decorative ply,
printing, by means of inkjet printing, a primer onto the transfer paper and/or onto the stamping film,
pre-curing the primer,
applying, at least in areas, the stamping film to the transfer paper by means of hot or cold stamping, whereby the decorative ply of the stamping film is transferred to the water transfer paper after the pre-curing of the primer, and
fully curing the primer and the decorative ply after the transfer of the decorative ply to the water transfer paper.

2. The method according to claim 1 , wherein the transfer paper comprises a water-soluble layer.

3. The method according to claim 1 , wherein the primer is a light-curing primer, wherein the primer is partially cured and fully cured by radiation.

4. The method according to claim 1 , wherein the primer is dried by means of IR radiation.

5. The method according to claim 1 , wherein the primer is printed on at an application temperature of from 20° C. to 75° C.

6. The method according to claim 1 , wherein the primer has a viscosity in the range of from 5 mPas to 100 mPas.

7. The method according to claim 1 , wherein the stamping film is applied in a roll-on method.

8. The method according to claim 1 , wherein, in a further step, at least one ink is printed by means of inkjet printing.

9. The method according to claim 8 , wherein, in a further step, at least one protective varnish is printed by means of inkjet printing onto the decorative ply or onto the ink.

10. The method according to claim 9 , wherein the ink or the protective varnish is fully cured by radiation.

11. The method according to claim 10 , wherein the ink and the protective varnish are fully cured together.

12. The method according to claim 1 , wherein the production of the decal and/or the decoration is effected in an inline manufacture.

13. The method according to claim 1 , wherein a carrier is applied to the decoration in a further step.
