Abstract
This disclosure describes substrate(s) formed with a three-dimensional (3D) feature thereon, and method(s) of printing the same. One method includes identifying a plurality of locations on a substrate surface where the three-dimensional feature will be formed, determining a height value of the three-dimensional feature at each location, assigning a grayscale value to each location based on the height value, and applying ink to the substrate surface at each location according to the assigned grayscale value.
Claims19
A method of printing at least one three-dimensional (3D) feature on a substrate, the method comprising:
- applying a layer of UV-curable material within a boundary of the at least one 3D feature on a surface of the substrate;
- curing the UV-curable material layer by directing UV light toward the applied UV-curable material layer;
- applying one or more additional layers of UV-curable material within the boundary of the at least one 3D feature on the surface of the substrate;
- and
- curing the one or more additional layer of UV-curable material by directing UV light toward each additional material layer after it is applied, wherein the cured material layers form at least a portion of the at least one 3D feature on the substrate;
- wherein at least two 3D features create at least two contact points, and wherein a portion of the substrate between the at least two 3D features has a thickness less than a remaining portion of the substrate.
A method of printing at least one three-dimensional (3D) feature on a glass container, the method comprising:
- applying a layer of UV-curable material within a boundary of the 3D feature to a surface of the glass container;
- curing the UV-curable material layer by directing UV light toward the applied UV-curable material layer;
- applying one or more additional layers of UV-curable material within the boundary of the at least one 3D feature on the surface of the glass container;
- and
- curing the one or more additional layers of UV-curable material by directing UV light toward each additional material layer after it is applied to form the at least one 3D feature on the glass container,
- wherein the at least one 3D feature comprises a bumper disposed at a contact point and circumferentially around the glass container, the bumper having a greater circumference than a remaining portion of the glass container.
A method of printing at least one three-dimensional (3D) feature on a substrate, the method comprising:
- applying a layer of UV-curable material within a boundary of the 3D feature to a surface of the glass substrate;
- curing the UV-curable material layer by directing UV light toward the applied UV-curable material layer;
- curing the one and more additional layers of UV-curable material by directing UV light toward each additional material layer after it is applies to form the at least 3D feature on the substrate,
- wherein the at least one 3D feature comprises a bumper disposed at a contact point, the bumper having a greater circumference than a remaining portion of the substrate, wherein at least two three-dimensional features create at least two contact points, and wherein a portion of the substrate between the contact points has a thickness less than a remaining portion of the substrate.
