Digital printing plastic container
View Patent ↗A plastic container includes a medium applied to a portion of the container. A digital image is applied to a portion of the medium, the digital image being comprised of a plurality of ink droplets. Methods for digital printing on a portion of a medium that is applied to a container are also disclosed.
1. A method for making a plastic article with a digitally printed image, the method comprising:
providing a plastic article having a surface;
providing a medium on at least a portion of the surface of the plastic article, the medium comprising a separately applied label as an in-mold label, a glued-upon label, a pressure-sensitive label, an adhesive label, or a heat transfer label;
moving the plastic article in a substantially vertical orientation to or by a station with a plurality of horizontally movable print heads configured for horizontal printing;
providing one or more of the plurality of horizontally movable print heads at a distance relative to the surface;
horizontally side printing, on the substantially vertically-oriented plastic article, a plurality of ink droplets on at least a portion of the separately applied label; and
curing the plurality of ink droplets.
2. The method of claim 1 , including confirming the presence of the medium on at least a portion of the surface.
3. The method of claim 2 , wherein a scanning device is used to confirm the presence or the accurate placement of the medium.
4. The method of claim 2 , wherein the presence of the medium is confirmed prior to printing the plurality of ink droplets on at least a portion of the medium.
5. The method of claim 1 , including simultaneously printing the plurality of ink droplets on two different portions of the article.
6. The method of claim 1 , wherein the diameter of the plurality of ink droplets ranges from about 10 microns to about 200 microns.
7. The method of claim 1 , wherein the diameter of the plurality of ink droplets ranges from about 30 microns to about 90 microns.
8. The method of claim 1 , wherein the plurality of ink droplets are provided with a range between about 200 to about 1200 drops per inch (DPI).
9. The method of claim 1 , wherein the plurality of ink droplets are provided with a range between about 300 to about 1200 drops per inch (DPI).
10. The method of claim 1 , wherein the digitally printed plurality of ink droplets form part of a digital image, and the digital image includes text, graphics, or text and graphics.
11. The method of claim 1 , wherein the curing takes place between 0.5 seconds and 5 seconds after the ink droplets contact the container surface.
12. A plastic container comprising:
a plastic container;
a medium comprising a separately applied label that is applied directly to a portion of the container as an in-mold label, a glued-upon label, a pressure-sensitive label, an adhesive label, or a heat transfer label; and
a digital image that is digitally printed on a portion of the separately applied label after the separately applied label has been applied to the portion of the container;
wherein the digital image is comprised of a plurality of printed ink droplets provided directly on at least a portion of the separately applied label, the ink droplets have diameters within the range of about 10 microns to about 200 microns and the ink droplets forming a digital image with a range between about 200 to about 1200 drops per inch (DPI).
13. The plastic container of claim 12 , wherein the medium includes one or more pre-printed portions.
14. The plastic container of claim 12 , wherein two or more separate mediums are applied to two or more different portions of the container.
15. The plastic container of claim 12 , wherein the plurality of printed ink droplets are cured.
16. The plastic container of claim 12 , wherein the medium is white or clear.
17. The plastic container of claim 12 , wherein the medium is comprised of one or more colors.
18. The method of claim 12 , including confirming the presence of the medium on at least a portion of the surface.
19. The method of claim 18 , wherein the presence of the medium is confirmed prior to printing the plurality of ink droplets on at least a portion of the medium.
20. The method of claim 18 , wherein a scanning device is used to confirm the presence or the accurate placement of the medium.
21. The method of claim 12 , wherein the plurality of ink droplets are horizontally side printed on a vertically upstanding plastic container.
22. The method of claim 12 , including simultaneously printing the plurality of ink droplets on opposing sides of the container.
