Method of making a film negative

1. A method of preparing a film negative, the method comprising the steps of:

(a) dispersing a UV ink in a desired pattern on a UV printing substrate; and

(b) curing the UV ink with a source of actinic radiation to crosslink and cure the UV ink and create the UV printed polymer layer in the desired pattern,

wherein the UV ink is at least substantially solvent-free, and

wherein the printing substrate does not contain an adhesive layer or an ink-receptive layer and has not been modified to be ink-receptive.

2. The method according to claim 1 , wherein the printing substrate comprises a transparent material selected from the group consisting of polyethylene terephthalate, polycarbonate, and polyethylene naphthalate.

3. The method according to claim 1 , wherein the UV ink is cured by exposure to the at least one UV light source at a wavelength output in the range of about between about 365 nm and about 405 nm.

4. The method according to claim 3 , wherein the step of curing the UV printing a curing time of the UV ink is accomplished by advancing the printing substrate relative to at least one UV light source at a speed of between about 16 inches per minute and about 3 inches per minute.

5. The method according to claim 1 , wherein the printing substrate contains an adhesive layer disposed on the printing substrate, wherein the adhesive layer is covered with a release liner, and wherein the UV ink is printed on a surface of the release liner.

6. The method according to claim 1 , wherein the UV ink is cured at a temperature of between about 60° F. and about 90° F.

7. The method according to claim 6 , wherein the UV ink is cured at a temperature of between about 70° F. and about 80° F.

8. The method according to claim 1 , wherein the UV ink comprises one or more photoinitiators, monomers, and binders.

9. The method according to claim 1 , wherein the UV ink comprises a four-color system comprising cyan, magenta, yellow and black.

10. The method according to claim 1 , wherein the UV ink is a single color ink, wherein said single color ink is black.

11. The method according to claim I, wherein the curing of the UV ink produces a surface morphology configured to improve air removal under vacuum, wherein the surface morphology defines a microchannel.

12. The method according to 1 , wherein the UV ink is not subjected to heating or drying step.

13. A film negative usable in the a process of imaging a flexographic printing element, wherein the film negative produced according to the method of claim 1 .

14. A method of preparing an I-plate using a liquid photopolymer resin, the method comprising the steps of:

(a) positioning a first film negative on a substantially planar transparent support surface, wherein the first film negative is configured in a first desired pattern;

(b) casting a layer of liquid photopolymer in direct or indirect contact with the first film negative;

(c) positioning a second film negative in alignment with and opposite the first film negative, the second film negative being in direct or indirect contact with the layer of liquid photopolymer, wherein the second film negative is configured to have a second desired pattern in alignment with the first desired pattern; and

(d) exposing actinic radiation through the first UV printed polymer layer and the second UV printed polymer layer to selectively crosslink and cure the liquid photopolymer layer in accordance with the first desired pattern and the second desired pattern,

wherein the first and second film negatives are produced in accordance with the method of claim 1 .

15. The method according to claim 14 , wherein the second desired pattern is dimensioned larger than the first desired pattern, thereby producing an island around the first desired pattern.
