Abstract

A method of printing a print media comprises printing an image onto a surface of a print media, and applying a protective coating over the surface of the print media using an analog printing process, wherein the protective coating comprises a plurality of micro openings.

First claim

The invention claimed is:

1. A method of printing a print media comprising:
printing an image onto a surface of a print media, wherein the surface of the print media includes an imaged region containing the printed image;
applying a protective coating over the surface of the print media at the imaged region using an analog printing process, wherein the protective coating comprises a plurality of micro openings; and
depositing an adhesive onto the applied protective coating to cause the adhesive to flow into the plurality of micro openings positioned over the imaged region.

2. The method as claimed in claim 1 , wherein applying a protective coating comprises distributing the plurality of micro openings over the surface of the print media in an even manner, using a repeating pattern, or using an even average density.

3. The method as claimed in claim 1 , comprising configuring the plurality of micro openings such that the protective coating deposits on:
10% to 70% of a surface area of the print media; or
30% of the surface area of the print media.

4. The method as claimed in claim 1 , comprising configuring the plurality of micro openings based on at least one of the following criteria:
a print media type;
a protective coating type; or
a subsequent coating type, wherein a subsequent coating is to be applied over at least a portion of the protective coating.

5. The method as claimed in claim 1 , wherein applying a protective coating comprises depositing a protective coating having a predetermined thickness to the surface of the print media.

6. The method as claimed in claim 5 , wherein the predetermined thickness is selected based on at least one of the following criteria:
a print media type;
a protective coating type; or
a subsequent coating type, wherein a subsequent coating is to be applied over at least a portion of the protective coating.

7. The method as claimed in claim 5 , wherein the protective coating comprises a thickness of between 0.5 μm to 4 μm.

8. The method as claimed in claim 1 , wherein the analog printing process comprises:
depositing the protective coating using a roller coating process, wherein the roller comprises a pattern to form the plurality of micro openings in an applied protective coating; or
depositing the protective coating using a mesh screen, wherein the mesh screen comprises a pattern to form the plurality of micro openings as the protective coating is deposited through the mesh screen.

9. The method as claimed in claim 1 , wherein the plurality of micro openings form a protective coating comprising a plurality of printed dots or lines.

10. The method as claimed in claim 9 , comprising using amplitude modulation halftoning techniques and/or frequency modulation halftoning techniques to control the size and/or density of the printed dots or lines and/or the size of the plurality of micro openings.

11. The method as claimed in claim 1 , further comprising:
depositing the adhesive over at least a portion of the protective coating.

12. A method of printing a print media comprising:
receiving a print media having an image printed on a surface thereof;
applying a protective coating over the surface of the print media including the printed image using an analog printing process, wherein the protective coating comprises a plurality of micro openings and wherein the surface includes a fixing portion that is to be adhered to another portion of the print media; and
depositing an adhesive over the protective coating that is applied over the surface of the print media including the printed image and on the fixing portion of the surface.

13. A method of forming a packaging product from a print media, the method comprising:
printing an image onto a surface of the print media, the surface including a fixing portion that is to be adhered to another portion of the print media;
applying a protective coating over the surface of the print media using an analog printing process, wherein the protective coating comprises a plurality of micro openings;
depositing an adhesive over the protective coating applied over the surface of the image including the printed image and on the fixing portion of the surface; and
shaping the print media into the packaging product.

14. The method as claimed in claim 13 , further comprising:
applying a lower percentage of the protective coating at the fixing portion than a portion of the surface other than the fixing portion.

15. An apparatus for printing a print media, the apparatus comprising:
a printing module to print an image onto a surface of a print media, wherein the surface of the print media includes an imaged region containing the printed image;
a coater module to apply a protective coating over the surface of the print media at the imaged region using an analog coating process, wherein the protective coating comprises a plurality of micro openings; and
a module to deposit an adhesive onto the applied protective coating to cause the adhesive to flow into the plurality of micro openings positioned over the imaged region.

16. The method as claimed in claim 11 , wherein the surface includes a fixing portion at which the print media is to be adhered, and wherein the method further comprises:
applying a lower percentage of the protective coating at the fixing portion than a portion other than the fixing portion.

17. The method as claimed in claim 12 , wherein applying the protective coating using an analog printing process comprises:
depositing the protective coating using a roller coating process, wherein the roller comprises a pattern based on a plurality of micro openings; or
depositing the protective coating using a mesh screen, wherein the mesh screen comprises a plurality of micro openings.

18. The method as claimed in claim 12 , further comprising:
applying a lower percentage of the protective coating at the fixing portion than a portion of the surface other than the fixing portion.

19. The apparatus as claimed in claim 15 , wherein the surface includes a fixing portion at which the print media is to be adhered, and wherein the coater module is further to apply a lower percentage of the protective coating at the fixing portion than a portion other than the fixing portion.

20. The apparatus as claimed in claim 15 , wherein to apply the protective coating, the coater module is to:
deposit the protective coating using a roller coating process, wherein the roller comprises a pattern based on a plurality of micro openings; or
deposit the protective coating using a mesh screen, wherein the mesh screen comprises a plurality of micro openings.
