Abstract

A printing process that reduces the amount of flash that occurs when printing to a surface of a plastic card. The printing can occur by a retransfer printing process. The printing process includes generating an image canvas that has rounded corners instead of the conventional right angle corners. The use of rounded corners on the image canvas reduces the amount of printing in the image canvas at the corners compared to an image canvas that has right angle corners, thereby reducing the amount of printing that is present that could form flash at the corners of the card surface.

First claim

The invention claimed is:

1. A method of printing an image on a surface of a plastic card, comprising:
printing an image canvas on a transferable printing receptive layer carried by a carrier layer, the printed image canvas including the image that is to be printed on the surface of the plastic card, the printed image canvas has an area that is larger than the surface of the plastic card, and the printed image canvas having a shape of a rounded rectangle with rounded corners; and
transferring a portion of the transferable printing receptive layer containing a portion of the printed image canvas from the carrier layer onto the surface of the plastic card;
wherein the printed image canvas reduces an amount of printing that is present that could form flash at corners of the surface of the plastic card upon transferring the portion of the transferable printing receptive layer from the carrier layer onto the surface of the plastic card.

2. The method of claim 1 , wherein the printing comprises dye or pigment printing.

3. The method of claim 2 , wherein printing the image canvas includes printing a primer on the transferable printing receptive layer, the printing of the primer begins at a location upstream of where the dye or pigment printing starts so that there is a buffer area of the primer before the start of the dye or pigment printing.

4. The method of claim 1 , wherein an area surrounding and bordering the printed image canvas comprises the transferable printing receptive layer.

5. The method of claim 1 , wherein the plastic card comprises a financial card having at least one of a magnetic stripe and an integrated circuit chip.

6. The method of claim 5 , further comprising data on the magnetic stripe and/or on the integrated circuit chip, and at least some of the data matches printed data on the printed image canvas.

7. The method of claim 5 , wherein the financial card includes the magnetic stripe, and the method further comprises encoding data on the magnetic stripe.

8. The method of claim 7 , wherein the encoding data on the magnetic stripe occurs prior to printing the image on the surface of the plastic card.

9. The method of claim 5 , wherein the financial card includes the integrated circuit chip, and the method further comprises programming data on the integrated circuit chip.

10. The method of claim 9 , wherein the programming data on the integrated circuit chip occurs prior to printing the image on the surface of the plastic card.
