Patent ID: 7562957

Claim:
A multi-pass printing method comprising: printing a first image including a combination of colors on a substantially translucent substrate using a first row of print heads within a printer head carriage during a first pass of the carriage, wherein the first row of print heads contain all the colors necessary to print the first multi-color image, wherein the substantially translucent substrate has a first side and a second side, and wherein the first multi-color image is printed on the second side; printing an at least partially opaque coating layer over the first multi-color image using a second row of print heads during a second pass of the carriage, wherein the first group of print heads and the second row of print heads are configured in a same printer head carriage, and wherein the at least partially opaque coating layer facilitates quality viewing of the first multi-color image from the first side of the substantially translucent substrate; and printing a second multi-color image over the at least partially opaque coating layer on an opposite side of the coating layer as the first multi-color image using a third row of print heads during a third pass of the carriage, wherein the third row of print heads are configured in a same printer head carriage as the first row of print heads and the second row of print heads, wherein the third row of print heads contain all the colors necessary to print the second multi-color image, and wherein the first, second, and third pass of the carriage results in printed substrate configured such that the first multi-color image is visible when looking through a first side of the substrate and the second multi-color image is visible when looking from a second side of the substrate.
