Abstract
A method comprises forming a first pattern on a first flat surface and forming an inverse of the pattern on a second flat surface. The method further comprises attaching the second flat surface to a roller to produce an embossing tool and applying pressure between the embossing tool and a substrate thereby forming a second pattern in the substrate. The substrate is coated with a radiation curable resin material. The method also comprises transferring ink to the substrate, the ink containing a catalyst, and coating the substrate with the second pattern in an electroless plating bath. The first pattern alternatively may be formed on a sleeve which is then attached to a drum/roller.
Claims17
A method, comprising:
- forming a first pattern on a first flat surface;
- forming an inverse of the pattern on a second flat surface;
- attaching the second flat surface to a ropier to produce an embossing tool;
- applying pressure between the embossing tool and a substrate thereby forming a second pattern in the substrate, wherein the substrate is coated with a radiation curable resin material;
- and
- coating the substrate with the second pattern in an electroless plating bath.
A method, comprising:
- forming a first pattern on a first flat surface;
- forming an inverse of the pattern on a second flat surface;
- attaching the second flat surface to a roller to produce an embossing tool;
- applying pressure between the embossing tool and a substrate thereby forming a second pattern in the substrate, wherein the substrate is coated with a radiation curable resin material;
- transferring ink to at least a portion of the substrate, said ink containing a catalyst;
- and
- coating the substrate with the second pattern in an electroless plating bath.
A method, comprising:
- creating a photomask;
- applying the photomask to a flexographic plate;
- exposing the photomask and flexographic plate to radiation to produce a printing plate based on said flexographic plate;
- and
- transferring a catalyst-based ink to the printing plate.
A method, comprising forming a first pattern on a sleeve;
- mounting said sleeve around a drum thereby forming an embossing tool;
- applying pressure between the embossing tool and a substrate thereby forming a second pattern in the substrate, wherein the substrate is coated with a radiation curable resin material;
- and
- coating the substrate with the second pattern in an electroless plating bath.
