Abstract
In an example of the disclosure, a priming lane and a non-priming lane are identified within an image frame to be printed by a printer. A line of molten wax is applied to the roller. The molten wax when cooled is to form a wax ridge upon the roller. The roller having the formed wax ridge is wetted with the primer. The wetted roller is rotated against the substrate to apply the primer. A first width of the wetted roller that does not include the wax ridge forms the priming lane upon the substrate. A second width of the roller that includes the wax ridge causes the primer to not transfer and thereby forms the non-priming lane upon the substrate.
Claims15
A method for selective application of a primer to a substrate, comprising:
- identifying, within an image frame to be printed by a printer, a priming lane where a primer is to be applied to a substrate and a non-priming lane where the primer is not to be applied to the substrate;
- applying a line of molten wax to a roller, the molten wax when cooled to form a wax ridge upon the roller;
- wetting with primer the roller having the formed wax ridge with the primer;
- and
- rotating the wetted roller against the substrate to apply the primer, wherein a first width of the wetted roller that does not include the wax ridge forms the priming lane upon the substrate, and wherein a second width of the roller that includes the wax ridge causes the primer to not transfer to the roller and thereby forms the non-priming lane upon the substrate.
A method for selective application of primer to a substrate, comprising:
- receiving data indicative of an image frame to be printed upon a substrate by a printer;
- identifying based upon the image frame data a priming lane within the image frame wherein a primer is to be applied to the substrate by a roller;
- identifying based upon the image frame data a non-priming lane within the image frame wherein the primer is not to be applied to the substrate;
- causing a streak of molten wax to be applied the roller, the molten wax to cool form a wax ridge upon the roller;
- applying the primer to the roller having the formed wax ridge;
- and
- applying the primer to the substrate by rotating the roller against the substrate, wherein the priming lane is formed upon the substrate using a width of the roller that does not include the wax ridge forms, and wherein the non-priming lane is formed upon the substrate as the wax ridge causes the primer to not transfer to the roller and thereby not transfer to the substrate.
A system to prepare a roller for selective application of primer to a substrate, comprising:
- a data receipt engine, to receive data indicative of an image frame to be printed upon a substrate by a printer;
- an identification engine, to identify based upon the data a priming lane within the image frame wherein a primer is to be applied to the substrate by a roller, and to identify based upon the data a non-priming lane within the image frame wherein the primer is not to be applied to the substrate;
- a wax application engine, to cause a wax application apparatus to apply a line of molten wax to a roller in consideration of the data, the molten wax when cooled to form a wax ridge upon the roller in a position such that a width of the roller that does not include the wax ridge is for forming the priming lane, and wherein the wax ridge upon the roller is to cause the primer to not transfer to the substrate and thereby is to form the non-priming lane.
