Abstract

An apparel printing system for printing on regions of tubular fabrics with repeating patterns includes a textile printer having a print head and a tubular platen that includes features on the platen surface to retain and register the tubular fabric on the platen surface during printing.

First claim

The invention claimed is:

1. A printing system for printing onto an article of apparel constructed with a fabric repeating pattern, the printing system comprising:
a printer including a framework and a print head;
a tubular platen having a drum connected to the framework by a platen support, wherein the print head is disposed proximate to the tubular platen; and
a platen surface extending around an outer region of the drum, the platen surface having a plurality of registration features extending throughout the platen surface to retain the article of apparel in a printing configuration,
wherein the plurality of registration features form a platen repeating pattern on the platen surface that corresponds to the fabric repeating pattern formed by a plurality of repeating features of the article of apparel.

2. The printing system according to claim 1 , wherein the registration features include raised portions separated by cavities.

3. The printing system according to claim 2 , wherein the raised portions are circular features.

4. The printing system according to claim 1 , wherein the platen repeating pattern is a reverse of the fabric repeating pattern.

5. The printing system according to claim 1 , wherein the registration features are geometric features positioned to retain the article of apparel.

6. The printing system according to claim 1 , wherein the article of apparel is a tubular knit textile.

7. The printing system according to claim 1 , configured to print a graphical design on a portion of the article of apparel.

8. The printing system according to claim 1 , wherein the platen repeating pattern is etched into the platen surface.

9. The printing system according to claim 8 , wherein the platen repeating pattern is the reverse of the fabric repeating pattern.

10. The printing system according to claim 1 , wherein the plurality of repeating features are round openings in the article of apparel.

11. The printing system according to claim 1 , wherein the plurality of repeating features are thickened regions of the article of apparel.

12. The printing system according to claim 1 , wherein the platen surface includes combinations of the plurality of registration features to accommodate various types of fabric repeating patterns.

13. The printing system according to claim 1 , wherein the printer includes at least one registration sensor.

14. The printing system according to claim 13 , wherein the at least one registration sensor is selected from the group consisting of a digital eye, a laser, a position sensor, a rotation sensor, a contact sensor, and a mechanical switch.

15. A method of printing on an article of apparel that includes a tubular portion of fabric that includes a pattern of repeating thickened regions formed in the article of apparel, the method comprising:
positioning the article of apparel on a tubular platen, wherein the tubular platen includes a plurality raised portions separated by cavities disposed on a platen surface of the tubular platen in a spaced apart configuration, wherein the plurality of raised portions are separated by cavities which form a platen surface pattern that is the inverse of the pattern of repeating thickened regions,
wherein the step of positioning the article of apparel includes inserting at least one thickened region of the repeating thickened regions into at least one cavity disposed on the platen surface; and
printing a design onto the article of apparel.

16. The method of claim 15 , wherein the step of positioning the article of apparel includes positioning the article of apparel on the tubular platen in a registration arrangement.

17. The method of claim 16 , wherein the step of positioning the article of apparel on the tubular platen in a registration arrangement includes advancing the article of apparel onto the platen surface until a leading edge of the article of apparel mates with a stop.

18. The method of claim 17 further comprising:
expanding the article of apparel prior to the step of positioning the article of apparel on a tubular platen.

19. The method of claim 15 further comprising the step of determining a position of the article of apparel on the tubular platen prior to the step of printing the design.

20. The method of claim 19 , wherein the step of determining the position of the article of apparel includes using a registration sensor.
