Definitions

  • the invention relates to a method and an apparatus for Applying a decor to an object in which the object is immersed in a liquid on which the decor floats to transfer the decor to the object.
  • US-A-4,348,246 and US-A-4,388,866 describe similar ones Transfer printing techniques, with the film being transferred Decor on a granulate layer or a deformable layer from pens.
  • US-A-4,436,571 describes a transfer print of the beginning mentioned type, in which the object to be printed in certain Point into the liquid with the decor floating on it is immersed, namely in a continuous movement obliquely down towards the flow and then obliquely upwards, also in the direction of the flow of the liquid.
  • US-A-4,407,881 (corresponding to DE-A-32 19 992) describes for the transfer printing mentioned at the outset a special configuration of the support film, which is a hydrophilic, deformable layer has, which can swell by absorption of water, and another layer overlaid on the hydrophilic layer and which is permeable to water in different ways, so that the hydrophilic layer more or less expanded.
  • US-A-4,229,239 describes a special embodiment of the Transfer printing technology mentioned at the beginning, in which the decor before preparing for transfer using a solvent so that it is easier to transfer from the object to the object supporting film triggers.
  • This activation of the decor takes place immediately with the prior art mentioned before applying the film with the decor on the free Water surface.
  • the can Dissolve the decor supporting film so that the decor alone (without the film) floats on the surface of the water and then Immerse the object to be decorated on this Item is applied.
  • US-A-4,269,650 also describes the addition of a solvent, to facilitate the detachment of the decor from the supporting film.
  • the one to be decorated Object two-dimensionally in a main plane of movement emotional.
  • the main plane of movement is defined by the fact that is spanned by the following vectors: That of the flow direction vector corresponding to the liquid and one perpendicular Vector (normal) to the liquid surface.
