PROCESS FOR DEPOSITING MULTIPLE FLUID LAYERS ON VARIOUS SUBSTRATES
Provided herein are methods for printing an image on a substrate using various methods of deposition in a single process. The methods may comprise a base layer application step wherein a base layer is applied to a portion of the substrate using a valve jet, or an inkjet printhead and a graphical application step wherein one or more ink layers are applied to a portion of the substrate (e.g., using an inkjet or a valve jet). Advantageously, the base layer may be applied only to substantially the same portion of the substrate as the one or more ink layers. The methods may further comprise a top coating step wherein a topcoat is applied to the printed portion of the substrate using a valve jet or an inkjet printhead.
1 . A method of printing an image on a substrate, the method comprising:
a base layer application step wherein a base layer is applied to the substrate using a valve jet or an inkjet printhead; and
a graphical application step wherein one or more ink layers are applied to a portion of the substrate.
2 . The method of claim 1 wherein the base layer is applied to the substrate using a valve jet or an inkjet printhead having a diameter of at least about 30 microns.
3 . The method of claim 1 wherein the base layer is applied to only a portion of the substrate.
4 . The method of claim 3 wherein the base layer is applied to substantially the same portion of the substrate as the one or more ink layers.
5 . The method of claim 1 wherein the base layer application step further comprises drying the substrate following application of the base layer.
6 . The method of claim 1 wherein the graphical application step comprises applying at least one white ink layer to the substrate.
7 . The method of claim 1 wherein the graphical application step comprises applying at least one colored ink layer to the substrate.
8 . The method of claim 1 wherein the graphical application step comprises applying at least one white ink layer to the substrate, and subsequently applying at least one colored ink layer to the substrate.
9 . The method of claim 1 wherein at least one ink layer is applied in a single process.
10 . The method of claim 1 wherein at least one ink layer is applied using an inkjet and at least one ink layer is applied using a valve jet.
11 . The method of claim 1 wherein the graphical application step further comprises drying the substrate following application of the one or more ink layers.
12 . The method of claim 1 further comprising a topcoat application step, wherein the topcoat is applied to only a portion of the substrate.
13 . The method of claim 12 wherein the topcoat is applied to substantially the same portion of the substrate as the one or more ink layers.
14 . The method of claim 12 wherein the topcoat is applied using a valve jet or an inkjet printhead having a diameter of at least about 30 microns.
15 . The method of claim 12 wherein the topcoat application step further comprises drying the substrate following application of the topcoat.
16 . The method of claim 1 wherein the base layer application step comprises applying a pretreatment composition to the substrate.
17 . The method of claim 16 wherein the pretreatment composition comprises:
a water-dispersing polymer resin component, in an amount of from about 5% by weight to about 30% by weight of the composition;
a coalescing solvent component, in an amount of from about 10% by weight to about 35% by weight of the composition; and
water, in an amount of from about 40% to about 90% by weight of the composition.
18 . The method of claim 17 wherein the pretreatment composition further comprises one or more additives selected from the group consisting of defoamers, wetting agents, adhesion promoters, and softening agents,
and wherein the pretreatment composition comprises the one or more additives in an amount of from 0% to about 10% by weight by weight of the composition.
19 . The method of claim 17 wherein the pretreatment composition does not comprise any plasticizers.
20 . A printed textile prepared according to the method of claim 1 .
