Abstract

An intaglio printing plate (2) has an array of imaging ink recesses (10); and, in each recess, an ink retaining structure comprising one or more regular arrays of raised elements (11) extending from the base of the recess to no more than 60 % of the height of the recess, ink retaining trenches extending between the raised elements, and wherein no more than 30 % of the area of the recess base is provided with raised elements.

Claims (21)

1. An intaglio printing plate having an array of imaging ink recesses; and, in each recess, an ink retaining structure comprising one or more regular arrays of raised elements extending from the base of the recess to no more than 60% of the height of the recess, ink retaining trenches extending between the raised elements, and wherein no more than 30% of the area of the recess base is provided with raised elements.
2. A plate according to claim 1, wherein no more than 20%
of the area of the recess base is provided with raised elements.
3. A plate according to claim 2, wherein 2.5-10% of the area of the recess base is provided with raised elements.
4. A plate according to claim 2, wherein 10-15% of the area of the recess base is provided with raised elements.
5. A plate according to claim 2, wherein 15-20% of the area of the recess base is provided with raised elements.
6. A plate according to any of the preceding claims, wherein the shortest distance between adjacent raised elements is no less than 100 microns.
7. A plate according to any of the preceding claims, wherein the raised elements have maximum lateral dimensions in the range 40-250 microns.
8. A plate according to any of the preceding claims, wherein the printing plate defines an ink wiping direction, the raised elements being defined such that no trench wider than the shortest distance between, adjacent raised elements extends by the size of the recess in the wiping direction.
9. A plate according to any of the preceding claims, wherein all trenches with a length substantially equal to the size of the recess and with a width no less than the shortest distance between adjacent raised elements extend at an angle in the range 15-75°, preferably substantially 45°, to the wiping direction.
10. A plate according to any of the preceding claims, wherein the ink retaining structure comprises a set of first raised elements defining a regular array.
11. A plate according to claim 10, wherein the ink retaining structure comprises a set of second, smaller raised elements dispersed between the first raised elements to assist in ink take up.
12. A plate according to claim 10 or claim 11, wherein all the first raised elements have the same shape in plan.
13. A plate according to any of the preceding claims, wherein the raised elements define in plan one or more of squares, rectangles, circles, ovals and the like.
14. A plate according to any of the preceding claims, wherein at least two of the imaging ink recesses have different ink retaining structures.
15. A plate according to any of the preceding claims, further comprising a set of further raised elements in each recess, the further raised elements having a height less than the first (and second) raised elements.
16. A plate according to any of the preceding claims, wherein the first raised elements define indicia.
17. A plate according to any of the preceding claims, wherein each recess defines a side wall which defines an angle of 65° or more with an imaginary extension of the surface of the plate.
18. A printing assembly comprising a printing plate according to any of the preceding claims; an inking system for supplying ink to the imaging ink recesses; a wiping mechanism for removing excess ink by wiping the printing plate in a wiping direction; and a system for transferring ink from the printing plate to a substrate.
19. An assembly according to claim 18, wherein the printing plate is mounted for rotary movement, the wiping mechanism comprising a wiping cylinder which abuts the printing plate and rotates in an opposite direction to the printing plate.
20. A document which has been printed using an intaglio printing plate according to any of claims 1 to 17.
21. A document of value, such as a banknote, according to claim 20.
