Abstract
A deposition device may deposit, on a substrate, a binder layer that includes a first set of magnetic flakes and a second set of magnetic flakes and may cause, when a temperature of the binder layer satisfies a temperature threshold (e.g., a Curie temperature of the first set of magnetic flakes), a magnetic field to be applied to the binder layer to cause the first set of magnetic flakes and the second set of magnetic flakes to be oriented according to the magnetic field. The deposition device may cause, when the temperature of the binder layer ceases to satisfy the temperature threshold, another magnetic field to be applied to the binder layer to cause only the second set of magnetic flakes to be oriented according to the other magnetic field.
Claims20
A method, comprising:
- depositing, by a deposition device and on a surface of a substrate, a binder layer that includes a plurality of magnetic flakes;
- applying, by the deposition device, a first magnetic field to the binder layer when a temperature of the binder layer satisfies a threshold, to cause the plurality of magnetic flakes to be oriented according to the first magnetic field;
- applying, by the deposition device, a second magnetic field to the binder layer when a temperature of at least a portion of the binder layer does not satisfy the threshold, to cause a subset of magnetic flakes, of the plurality of magnetic flakes, to be oriented according to the second magnetic field;
- and
- curing, by the deposition device, the binder layer.

A method, comprising:
- depositing, by a deposition device and on a substrate, a binder layer that includes a plurality of magnetic flakes;
- applying, by the deposition device, a first magnetic field to the binder layer when a temperature of the binder layer satisfies a threshold, to cause one or more first magnetic flakes, of the plurality of magnetic flakes, to align with one or more magnetic field lines of the first magnetic field;
- and
- applying, by the deposition device, a second magnetic field to the binder layer when a temperature of at least a portion of the binder layer does not satisfy the threshold, to cause one or more second magnetic flakes, of the plurality of magnetic flakes, to align with one or more magnetic field lines of the second magnetic field.
