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.

A method, comprising:
- applying, by a device, a first magnetic field to a binder layer when a temperature of the binder layer satisfies a threshold, to cause a plurality of magnetic flakes of the binder layer to be oriented according to the first magnetic field;
- causing, by the device, a temperature of a first portion of the binder layer to not satisfy the threshold;
- applying, by the device, a second magnetic field to at least a second portion of the binder layer when the temperature of the first portion of the binder layer does not satisfy the threshold to cause a subset of the plurality of magnetic flakes included in the second portion to be oriented according to the second magnetic field;
- and
- curing, by the device, the binder layer.
A method, comprising:
- applying, by a device, a first magnetic field to a binder layer when a temperature of the binder layer satisfies a first threshold temperature, to cause at least a first set of magnetic flakes of the binder layer to be oriented according to the first magnetic field;
- causing, by the device, the temperature of the binder layer to not satisfy the first threshold temperature and to satisfy a second threshold temperature;
- and
- applying, by the device, a second magnetic field to the binder layer when the temperature of the binder layer does not satisfy the first threshold temperature and satisfies the second threshold temperature, to cause a second set of magnetic flakes of the binder layer to be oriented according to the second magnetic field,
- wherein the first set of magnetic flakes is different from the second set of magnetic flakes.
A method, comprising:
- applying, by a device, a first magnetic field to a binder layer when a temperature of the binder layer satisfies a threshold, to cause one or more first magnetic flakes, of the binder layer, to align with one or more first magnetic field lines of the first magnetic field;
- causing, by the device, a temperature of a first portion of the binder layer to not satisfy the threshold;
- and
- applying, by the device, a second magnetic field to at least a second portion of the binder layer when the temperature of the first portion of the binder layer does not satisfy the threshold to cause one or more second magnetic flakes, of the binder layer, to align with one or more second magnetic field lines of the second magnetic field.
