Abstract

A system is provided that includes a first computer that can communicate with a second computer. The second computer sends information to the first computer that includes a desired ink color and optionally includes information of other desired ink properties. The first computer includes a database of data for predicting color data of ink formulations using a selected ink base color set, a software program for selecting an ink formulation based on data for a desired ink, and a software program for sending information to the second computer to display the color of the selected ink formulation on a color monitor connected to the second computer. The ink base color set can be selected to provide other desired properties for the ink, such as low cost, light fastness, or chemical resistance.

Claims

1. A system for providing a formulation that will produce a color matching a desired color, comprising:

a first computer that can communicate with a second computer, said first computer comprising

(a) a database for predicting color produced by formulations prepared using a set of materials;

(b) a color matching program for using the database to calculate a formulation that will produce a predicted color matching the desired color;

(c) a software program for sending information to the second computer to display the predicted color on a color monitor connected to the second computer.

2. A system according to claim 1, wherein the software program of (c) can send information to the second computer to display the desired color on the monitor along with the predicted color.

3. A system according to claim 2, wherein the software program of (c) can send information to the second computer to display how the predicted color and the desired color would appear under different lighting conditions.

4. A method for making an ink with a print color matching a desired print color, comprising steps of:

receiving with a first computer color information for the desired print color from a second computer;

accessing with the first computer a database for predicting print color for ink formulations;

accessing with the first computer a color matching program to select an ink formulation having a print color matching the desired print color.

5. A method according to claim 4, wherein said first computer and said second computer are connected by a global communication network.

6. A method according to claim 4, further comprising steps of providing the ink formulation to automated manufacturing equipment and manufacturing an ink according to the ink formulation.

7. A method for modifying an ink formulation, comprising the steps of:

(a) inputting to a first computer a desired color change for a print color of a first ink formulation;

(b) accessing with the first computer a color match program to produce a second ink formulation having a print color with the desired color change;

(c) transmitting to a second computer display data to display on a monitor the print color of the first ink formulation and a print color of the second ink formulation.

8. A method for comparing a print color to a desired color, comprising transmitting from a first computer to a second computer display information to display on a monitor the print color and the desired color, wherein the display data includes data to display the print color and the desired color as they would appear under at least two different light sources.

9. A method of formulating ink, comprising steps of:

inputting to a first computer data for a desired print color and at least one parameter selected from the group consisting of;

ink properties, type of ink, cost, printer identity, printing process parameters, press equipment parameters, press speed, substrate type, substrate color, and combinations thereof;

accessing with the first computer information for predicting print color for ink formulations using a set of ink base colors selected based on the at least one further parameter,

using a color matching software program to select an ink formulation for the at least one further parameter having a desired match to the desired color.

10. A method of providing two ink formulations, comprising steps of:

selecting a first ink formulation by the method of claim 9 and

selecting a second ink formulation by the method of claim 9,

wherein the desired print color is the same for the first ink formulation and the second ink formulation and further wherein at least one parameter is different for the first ink formulation and the second ink formulation.

11. A method according to claim 10, wherein the predicted print color for the first ink formulation has no more than a specified color difference compared to the predicted print color for the second ink formulation.

12. A method according to claim 10, wherein the first computer transmits to a second computer display data to display on a monitor the print color of the first ink formulation and the print color of the second ink formulation.

13. A method according to claim 12, wherein the first computer further transmits to the second computer display data to display on the monitor the desired color.

14. A method according to claim 10, wherein the at least one parameter comprises type of ink.
