Abstract
A scanning laser having a wavelength compatible with a coating binder so as to cure it as the laser scans and irradiates the coating on a moving web. A system and method for curing flakes by providing a scanning laser which scans across a moving coated substrate in a magnetic field allows images to be formed as magnetically aligned flakes are cured into a fixed position. The images have regions of cured aligned flakes. The scanning laser cures the magnetically aligned flakes within it region it irradiates. Alternatively an array of lasers can be used wherein individual lasers can be switched on and off to fix irradiated coating as a moving web is moved at a high speed.
Claims21
(canceled)
A system comprising:
- one or more magnetic assemblies;
- and
- a source to cure a region of a substrate while the substrate is on a path associated with the one or more magnetic assemblies.
A method comprising:
- moving a substrate along a path that is associated with the one or more magnetic assemblies;
- and
- curing a sub-region of the substrate while the substrate is moving along the path.
A method comprising:
- moving at least a portion of substrate around a cylinder;
- and
- curing a sub-region of the substrate while at least the portion of the substrate is moving around the cylinder.
