Abstract

The disclosure is related to printing an image as a multi-layered textured image on a substrate. The printing system prints one or more layers of a texture of the image as a base layer on the substrate and the image above the base layer. The base layer includes one or more layers of the texture. The printing system prints the texture using the ink from the print heads of the printing system. The process of printing a multi-layered textured image can include printing one or more layers of texture as a base layer on the substrate, printing one or more layers of white ink above the base layer, and printing one or more layers of the image above the white layers. The printing system can also insert one or more blank layers between different types of layers, e.g., texture layers, white layers and image layers.

First claim

I claim:

1. A method for multi-layered textured printing based on a maximum desired droplet count, the method comprising:
receiving information regarding a number of a first plurality of layers in which an image is to be printed on a substrate by an ink jet print head based printing system in a multi-layer mode;
determining a number of a second plurality of layers of a texture of the image, the number of second plurality of layers being a function of an intensity of a given pixel of the texture and a desired maximum ink droplet count of the texture, wherein the desired maximum ink droplet count of the texture is based on a desired thickness of the given pixel of the texture; and
generating a set of instructions to cause one or more print heads of the printing system to print the image with the texture as a plurality of layers on the substrate, wherein each layer of the plurality of layers has a corresponding counter to store the desired maximum ink droplet count of the texture, the set of instructions causing the printing system to perform a sequence of printing steps comprising:
executing an instruction to print the second plurality of layers of the texture on the substrate by using inks of multiple colors, wherein the second plurality of layers has a corresponding first counter which decrements, from a desired maximum ink droplet count for the second plurality of layers of the texture, a pre-determined value when the one or more print heads of the printing system deposit an ink droplet on the substrate,
in response to the first counter of the desired maximum droplet count for the second plurality of layers of the texture dropping to or below zero, executing an instruction to insert a blank layer within the sequence of printing steps for the image, insertion of the blank layer within the sequence of printing steps for the image causing the printing system not to deposit any ink on the substrate for the blank layer and causing a corresponding second counter to not decrement the pre-determined value,
executing an instruction to print one or more layers of white ink after the inserted blank layer, and
in response to a third counter of a desired maximum droplet count for the one or more layers of white ink dropping below zero, executing an instruction to print a first plurality of color layers of the image on the one or more layers of white ink.

2. The method of claim 1 , wherein generating the set of instructions includes:
executing an instruction to insert a first set of blank layers above the second plurality of layers of the texture before printing the one or more layers of substantially white ink; and
executing an instruction to insert a second set of blank layers above the one or more layers of substantially white ink before printing the first plurality of layers of the image.
