Abstract

Abstract A method for printing or exposing photosensitive media is disclosed herein. The method uses standard spatial light modulators (10) with standard addressing circuitry. The data is written to the device (10) for the first row, the photosensitive media is exposed to the light reflected from the device, and the device is turned off. The data from the first row is then written to the second line of the device (14), and new data is loaded into the first line (12) of the device. The media is again exposed. This is repeated until the entire region of the drum is completely exposed. The device (10) can be repositioned to cover a different region of the drum and the process would be repeated.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 125 words
A method of printing using a least one spatial light modulator, said method comprising: a) establishing a process for printing lines of data, wherein said process further comprises: i) writing data to the addressing circuitry for said modulator to form an image; ii) illuminating said modulator with light from a light source; iii) reflecting said light to a photosensitive media with said modulator such that said light reflected as said images; iv) writing new data to the addressing circuitry such that each line of data previously on said addressing circuitry is written to a row of said addressing circuitry adjacent the position of said line before a reset; and b) repeating said process until a predetermined region on said photosensitive media has been completely exposed.
Claim 2
Dependent Claim 27 words
A method as claimed in claim 1 and including the step of repositioning said at least one modulator to expose a different region on said photosensitive media.
Claim 3
Dependent Claim 18 words
The method of claim 1 or claim 2, wherein said spatial light modulator is a deformable mirror device.
Claim 4
Independent Claim 13 words
The method of any preceding claim, wherein said photosensitive medium is a negative.
Claim 5
Dependent Claim 14 words
The method of claim 4, wherein said negative is for a printed circuit board.
Claim 6
Dependent Claim 14 words
The method of claim 4, wherein said negative is for an offset printing plate.
Claim 7
Independent Claim 19 words
The method of any of claims 1, 2 or 3, wherein said photosensitive media is a finished photographic product.
Claim 8
Dependent Claim 14 words
The method of claim 7, wherein said photographic products is a printed circuit board.
Claim 9
Dependent Claim 14 words
The method of claim 7, wherein said photographic product is an offset printing plate.
Claim 10
Dependent Claim 12 words
The method of claim 7, wherein said photographic is a film positive.
Claim 11
Dependent Claim 12 words
The method of claim 7, wherein said photographic is a paper positive.
Claim 12
Dependent Claim 11 words
A printer arranged to perform the method of any preceding claim.
Claim 13
Dependent Claim 13 words
A photographic product, being the photographic product of any claims 7 to 11.
