Abstract

Example implementations relate to a printing an image on a substrate and printing an ultraviolet-sensitive finishing mark on the substrate using ultraviolet-sensitive ink. The ultraviolet-sensitive finishing mark can be visible under ultraviolet light.

Claims

1. A method comprising:

printing an image on a substrate; and

printing an ultraviolet-sensitive finishing mark, using ultraviolet-sensitive ink, on the substrate within a print area that is defined by a boundary of the image,

wherein the ultraviolet-sensitive finishing mark is visible under ultraviolet light.

2. The method of claim 1, further comprising:

preparing a digital layout that includes a digital representation of the image and a digital representation of the ultraviolet-sensitive finishing mark,

wherein the printing the image is performed in accordance with the digital representation of the image, and the printing the ultraviolet-sensitive finishing mark is performed in accordance with the digital representation of the ultraviolet-sensitive finishing mark.

3. The method of claim 1, wherein the ultraviolet-sensitive finishing mark is selected from among a cut mark, a fold mark, a barcode, and a finishing instruction.

4. The method of claim 1, wherein the ultraviolet-sensitive ink is non-opaque.

5. The method of claim 1, wherein the print area extends from a first edge of the substrate to a second edge of the substrate.

6. The method of claim 1, wherein the printing the ultraviolet-sensitive finishing mark prints the ultraviolet-sensitive finishing mark on top of the image.

7. The method of claim 1, wherein the printing the image and the printing the ultraviolet-sensitive finishing mark are performed by liquid electrophotographic printing.

8. The method of claim 2, further comprising:

outputting a print that includes the substrate having the image and the ultraviolet-sensitive finishing mark printed thereon;

illuminating the print with ultraviolet light to reveal the ultraviolet-sensitive finishing mark; and

finishing the print in accordance with the ultraviolet-sensitive finishing mark revealed by the illuminating.

9. A print system comprising:

a printer that includes visible ink and non-opaque ultraviolet-sensitive ink,

wherein the printer is to;

print an image on a substrate using the visible ink,

print an ultraviolet-sensitive finishing mark on the substrate on top of the image using the ultraviolet-sensitive ink, and

output a print that includes the substrate having printed thereon the image and the ultraviolet-sensitive finishing mark,

wherein the ultraviolet-sensitive finishing mark is visible under ultraviolet light.

10. The print system of claim 9, wherein the printer is a liquid electrophotographic printer.

11. The print system of claim 9, wherein the printer is an inkjet printer,

12. The print system of claim 9, further comprising a layout module to prepare a digital layout that includes a digital representation of the image and a digital representation of the ultraviolet-sensitive finishing mark,

wherein the digital layout is transmitted to the printer, and the printer produces the print in accordance with the digital layout.

13. The print system of claim 9, further comprising:

an ultraviolet light source to make visible the ultraviolet-sensitive finishing mark under ultraviolet light; and

a print finisher to finish the print in accordance with ultraviolet-sensitive finishing mark made visible by the ultraviolet light source.

14. A print comprising:

a substrate;

an image printed on the substrate; and

an ultraviolet-sensitive finishing mark printed on the substrate in a print area that is defined by a boundary of the image,

wherein the ultraviolet-sensitive finishing mark is visible under ultraviolet light.

15. The print of claim 14, wherein the ultraviolet-sensitive finishing mark is selected Thorn among a cut mark, a fold mark, a barcode, and a finishing instruction.
