 Production of laminated card with printed magnetically encodable stripe

Details

Assignee: Addressograph Multigraph Corp. (Cleveland, OH)
Primary Examiner: Wityshyn; Michael G.

Attorney, Agent or Firm: Goldstein; S. L., Fleck; H.

In production of a credit card or other magnetically encodable articles, a thermoplastic surface laminate layer is thermally tacked to a core stock layer and a magnetically encodable stripe is printed, for example, silk screened, on the laminate-core stock assembly. The resulting assembly is laminated to provide a smooth magnetic stripe having minimal distortion.

DETAILED DESCRIPTION It is therefore an object of the present invention to provide a method for providing a magnetically encodable card in which a magnetically encodable area is printed on a lamina and in which the provision of a flat card and a flat, smooth magnetic stripe are facilitated.
It is also an object of the present invention to provide a method for producing a credit card having a magnetically encodable stripe printed on a lamina within dimensional tolerances required of credit cards.
It is a specific object of the present invention to provide a method for making a magnetically encoded card in which a surface laminate is tacked on a core layer prior to printing of the magnetic stripe on the surface laminate, a magnetically encodable area is printed on the tacked surface laminate, and in which lamination of the surface laminate on the core layer is then performed.
It is a general object of the present invention to provide a relatively low cost and highly reliable method of providing a flat, smooth magnetically encodable area in a lamina of a magnetically encodable card or the like.
Briefly stated, in accordance with the present invention, there is provided a method for producing a card having a magnetically encodable area in a lamina in which provision of a flat card and nondistorted magnetically encoded area is facilitated.
A core stock is provided, a surface laminate is tacked to the core stock but not laminated thereto.
The magnetically encoded area is printed on the surface laminate and the surface laminate is then laminated to the core stock.
In this manner, distortion of the core stock and magnetic stripe printed thereon is minimized.
