Abstract
A method of printing a toner, including: rotating a cylinder having a printing plate with a fixed pattern; transferring a toner from a vessel onto the fixed pattern of the printing plate, in which the toner includes a pigment with a metallic reflective layer; and transferring the toner onto a substrate; in which the fixed pattern defines select portions of an image; and in which the toner correlates to the selected portions of the image is disclosed.
Claims18
A method of printing a toner, comprising:
- rotating a cylinder having a printing plate with a fixed pattern;
- transferring a toner from a vessel onto the fixed pattern of the printing plate, wherein the toner is a dry powder, and includes a pigment with a metallic reflective layer;
- and
- transferring the toner onto a substrate,
- wherein the fixed pattern defines select portions of an image,
- wherein the toner correlates to the select portions of the image,
- wherein the pigment includes a single cavity or a dual cavity, and
- wherein the pigment is a color shifting pigment.
A method of printing a toner, comprising:
- rotating a cylinder having a printing plate with a fixed pattern;
- transferring a toner from a vessel onto the fixed pattern of the printing plate, wherein the toner is a dry powder, and includes a pigment with a metallic reflective layer;
- transferring the toner onto a substrate, wherein the fixed pattern defines select portions of an image, the toner correlates to the select portions of the image, and the pigment includes a single cavity or a dual cavity;
- transferring a second toner onto a second fixed pattern of a second printing plate;
- and
- transferring the second toner onto the substrate, wherein the second fixed pattern defines different select portions of the image, and the second toner correlates to the different select portions of the image.
A method of printing a toner, comprising:
- rotating a cylinder having a printing plate with a fixed pattern;
- transferring a toner from a vessel onto the fixed pattern of the printing plate, wherein the toner is a dry powder, and includes a pigment with a metallic reflective layer;
- and
- transferring the toner onto a substrate, wherein the fixed pattern defines select portions of an image, the toner correlates to the select portions of the image, the pigment includes a single cavity or a dual cavity, and image exhibits a color shift when viewed off a perpendicular angle.
A method of printing a toner, comprising:
- rotating a cylinder having a printing plate with a fixed pattern;
- transferring a toner from a vessel onto the fixed pattern of the printing plate, wherein the toner is a dry powder, and includes a pigment with a metallic reflective layer;
- and
- transferring the toner onto a substrate;
- wherein the fixed pattern defines select portions of an image;
- wherein the toner correlates to the select portions of the image;
- and
- wherein the pigment is present in the toner to provide an area with complete toner coverage having 5% pigment coverage by area percentage on the substrate.
