Invention Name: Applying a matte laminate finish to a card to allow detection by a light sensor

On demand thermal transfer card printers can apply a matte laminate to a card or produce a clear card with a matte finish so it can be sensed by a light sensor.

It can be difficult to sense a clear laminate or a clear card. The reason for this is that most sensors use a light source and a light sensor, sensing a card when the light from the light source reflects off the laminate to the light sensor. However, with clear laminate, the light does not reflect, rather it passes through the laminate. This causes the light sensor to not receive reflected light and therefore to not sense the presence of the laminate.

It is often desirable to apply clear laminates to cards, so a solution is needed for card printers using a clear laminate that can be sensed within by a light sensor. A laminate is needed that provides a clear finish yet would still be capable of reflecting light to a sensor.

A clear, matte laminate applied to a card could reflect light for a sensor and still provide a clear finish for the user. A matte laminate is a clear surface with small raised portions that provide a non-shiny finish that provides a diffuse reflection of light shone on the card. The matte laminate can be placed on the entire laminate or part of the laminate. When the light source illuminates the matte laminate, some of the light may pass through the laminate, but some may be reflected so it...
