Abstract

A method for printing ink on a substrate comprising the steps of coating a glass substrate with an adhesion promoter, depositing one or more layers of ink on the coated substrate, and laminating the imaged substrate. The substrate can be a glass substrate, and the adhesion promoter can include a silane material, powder coating, organophosphate primer suspended in isopropanol.

First claim

We claim:

1. A method for printing ink on a substrate comprising:
pretreating a glass substrate, wherein pretreating includes coating the glass substrate with an adhesion promoter, wherein the adhesion promoter is a silane material, a powder coating, or an organophosphate material, and wherein the adhesion promoter increases adhesion of an ink to the substrate;
depositing one or more layers of ink directly on the adhesion promoting layer of the pretreated glass substrate;
overprinting the deposited one or more layers of ink with an overcoat;
curing the overprinted glass substrate to encapsulate the deposited one or more layers of ink; and
depositing a powder coating on the overprinted substrate before curing the overprinted glass substrate, wherein the powder coating includes material selected from the group consisting of inorganic particles, organic particles, thermally activated materials, components which absorb ultraviolet radiation, and combinations thereof.

2. The method of claim 1 wherein the step of pretreating further comprises cleaning the glass substrate of contaminants prior to coating the glass substrate with the adhesion promoter.

3. The method of claim 1 wherein the step of depositing one or more layers of ink further comprises depositing a layer of white ink or inkjetting one or more layers of ink.

4. The method of claim 1 wherein the substrate is a glass substrate with a thickness ranging from 0.1 mm to 2.2 mm.

5. The method of claim 1 wherein the substrate is planar or three dimensional.

6. The method of claim 4 , wherein the glass substrate is chemically strengthened.
