1. A process for printing on a substrate using a printer and a material dispensed from the printer, comprising:
- positioning the substrate on the printer;
printing a first layer of the material onto the substrate, wherein the first layer is printed with a pattern of openings in the first layer;
partially curing the first layer by subjecting the first layer to a first predetermined radiation event characterized by a first radiation;
printing a second layer of material over the first layer; and
fully curing the second layer and fully curing the first layer by subjecting the first layer and the second layer to a second predetermined radiation event characterized by a second radiation, wherein the second layer is partially transparent to the second radiation.

Abstract
A process for printing multiple layers on a fabric or other material using UV-curable ink that includes a step of printing a first layer on the material and another step of partially curing the first layer. A next step includes printing a partially UV-transparent layer over the first layer and fully curing the UV-transparent layer while simultaneously fully curing the first layer.

10. A process for printing on a substrate that has an uneven top surface, comprising:
-
positioning the substrate on a printer; printing a first layer of a material onto the uneven top surface of the substrate; partially curing the first layer by exposing the first layer to a first predetermined radiation event; allowing the first layer to coalesce such that a top surface of the first layer is smoother than the uneven top surface of the substrate; printing a second layer of material over the first layer; and curing the second layer and fully curing the first layer by subjecting the second layer to a second predetermined radiation event; wherein the second layer coalesces during curing, such that a top surface of the second layer is smoother than the top surface of the first layer. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A process for printing onto a substrate using a printer comprising:
-
positioning the substrate on the printer; printing a first layer of material on the substrate, the first layer having a pattern of openings; partially curing the first layer by subjecting the first layer to a first radiation event; printing a second layer of material over the first layer; and partially curing the second layer and further curing the first layer by subjecting the second layer to a second radiation event; wherein the first layer of material expands into the pattern of openings as it is cured to at least partially fill in the pattern of openings. - View Dependent Claims (20, 21, 22, 23, 24)
