Abstract
A method for printing identity cards having blind hole-shaped recesses involves filling the recess at least partly with an element at the moment of printing so that the bottom of the recess is pressed against the printing surface. The elements are either firmly mounted on the back pressure surface of the apparatus or movably mounted in this surface. In the second case the elements can disappear into the back pressure surface if necessary.
Claims14
A method of printing on cards having opposing parallel surfaces which are substantially planar, one of said opposing parallel surfaces including a blind hole-shaped recess with a membrane at a maximum depth of the recess, a printed pattern being transferred to the other of the opposing parallel surfaces by means of a printing plate which presses the card against a surface serving as a support during the printing operation, comprising the steps of:
- introducing an element into the recess which at least partially fills the recess;
- and
- holding the membrane in the printing plane with said element to stabilize said membrane against the pressure of the printing plate towards the support surface.
An apparatus for printing on cards having opposing parallel surfaces which are substantially planar, one of said opposing parallel surfaces including a blind hole-shaped recess with a membrane at a maximum depth of the recess, a printed pattern being transferred to the other of the opposing parallel surfaces, comprising:
- a support surface for supporting each card during the printing operation;
- a printing plate for pressing said each card against the support surface;
- and
- an element on the support surface for being introduced into the recess and stabilizing the membrane against the pressure of the printing plate towards the support surface during the printing operation.
An apparatus for printing on cards having opposing parallel surfaces which are substantially planar, one of said opposing parallel surfaces including a blind hole-shaped recess with a membrane at a maximum depth of the recess, a printed pattern being transferred to the other of the opposing parallel surfaces, comprising:
- a support surface for supporting each card during the printing operation;
- a printing plate for pressing said each card against the support surface;
- and
- an element movably disposed in said support surface for being introduced into the recess and stabilizing the membrane against the pressure of the printing plate towards the support surface during the printing operation.
