Abstract
A method for printing on a receiver with a plurality of colored dry inks and a dry white ink, the method includes providing a look-up table having a set of one dimensional look-up tables for each of the colored inks and black inks; inputting a value to each of the one dimensional look-up tables, which value corresponds to a laydown at each pixel location of the receiver; wherein the look-up table determines a laydown of white ink at each pixel location depending on the laydown of the colored inks and black ink; and determining an amount of white ink to laydown by computing a value from the determined white laydowns of each look-up table.

A method for printing on a receiver with a plurality of colored dry inks and a dry white ink, the method comprising the steps of:
- (a) providing a look-up table having a set of one dimensional look-up tables for each of the colored inks and black ink:
- (b) inputting a value to each of the one dimensional look-up tables, which value corresponds to a laydown at each pixel location of the receiver;
- wherein the look-up table determines a laydown of white ink at each pixel location depending on the laydown of the colored inks and black ink;
- (c) determining an amount of white ink to laydown by computing a value from the determined white laydowns of each look-up table, wherein the computing step includes choosing an average of the white laydown from each of the look-up tables.

A method for printing on a receiver with a plurality of colored dry inks and a dry white ink, the method comprising the steps of:
- (a) providing a look-up table having a set of one dimensional look-up tables for each of the colored inks and black ink;
- (b) inputting a value to each of the one dimensional look-up tables, which value corresponds to a laydown at each pixel location of the receiver;
- wherein the look-up table determines a laydown of white ink at each pixel location depending on the laydown of the colored inks and black ink;
- (c) determining an amount of white ink to laydown by computing a value from the determined white laydowns of each look-up table, wherein the computing step includes choosing a maximum white laydown from each of the look-up tables.

A method for printing on a receiver with a plurality of colored dry inks and a dry white ink, the method comprising the steps of:
- (a) providing a transform which includes transforms for each of the colored inks and black inks;
- (b) inputting a value to each of the transforms, which value corresponds to a laydown at each pixel location of the receiver;
- wherein the transform determines a laydown of white ink at each pixel location depending on the laydown of the colored inks and black ink;
- (c) determining an amount of white ink to laydown by computing a value from the determined white laydowns of each transform, wherein the computing step includes choosing an average of the white laydown from each of the transforms.
