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 matching print colors for different ink customer orders, comprising:

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

(a) a database of data for predicting color data of ink formulations using an ink base color set,

(b) a software program for selecting an ink formulation based on data for a desired ink, and

(c) 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.

2. A system according to claim 1, further comprising an automated dispensing machine digitally connected to said first computer for receiving said selected ink formulation from said first computer and manufacturing an ink of said ink formulation.

3. A system according to claim 2, wherein said ink that is manufactured is a lithographic ink.

4. A system according to claim 1, wherein said first computer calculates data of said desired ink color to the server in L*, a*, b*-type coordinates.

5. A system according to claim 1, wherein said first computer can communicate with said second computer using a global communication network.

6. A system according to claim 1, wherein said data for a desired ink is selected from the group consisting of type of substrate, color of substrate, print process, printing equipment, desired ink cost, at least one desired ink property, and combinations thereof.

7. A system according to claim 1, wherein the software program of (c) sends information to the second computer to display the color of the selected ink formulation in a selected kind of lighting.

8. A system according to claim 1, wherein said first computer further includes a software program for modifying the selected ink formulation according to further data input from said second computer.

9. A system according to claim 1, wherein said base color set is a lithographic ink base color set.

10. A system according to claim 1, where in said first computer further includes a program that identifies the selected ink formulation with a code and stores the formulation and code information.

11. A system according to claim 1, wherein said base color set includes base colors for inks having a property selected from the group consisting of chemical resistance, lightfastness, radiation curable, heat resistance, foil stampability, UV-coatable, laser imprintable and combinations of these.

14. A method according to claim 2, wherein the ink manufactured is a lithographic ink.

12. A method for making an ink of a desired color, comprising steps of:

receiving color information for the desired ink color by a first computer from a second computer, wherein said first computer and said second computer are connected by a global communication network;

accessing with the first computer a database of available ink colors;

comparing the desired ink color with colors of ink formulations and selecting an ink formulation within a selected color difference;

providing the ink formulation from the first computer to a third computer in communication with the first computer;

manufacturing an ink according to the ink formulation received by the third computer.

13. A method according to claim 12, wherein said manufacturing step is carried out by automated dispensing equipment connected to the third computer.

15. A method according to claim 12, wherein the ink that is manufactured is a flexographic ink.

16. A method according to claim 12, wherein the ink that is manufactured is a gravure ink.

17. A method of printing on a substrate, comprising steps of making an ink according to claim 12 and printing the ink on the substrate using an offset printing process.

18. A method of printing on a substrate, comprising steps of making an ink according to claim 12 and printing the ink on the substrate using a flexographic printing process.

19. A method of printing on a substrate, comprising steps of making an ink according to claim 12 and printing the ink on the substrate using a gravure printing process.
