Summary of the invention:
The invention discloses a kind of color laser phototypesetting sheet, purpose is to provide a kind of photosensitive material that laser photocomposing machine exposure black white image comes the display color stereo-picture of using.The stereo lamp box sheet that utilizes this material to make has fabulous sharpness, stereoscopic sensation and density contrast.
Principle of the present invention is, RGB three colouring components of stereo-picture are reassembled into a monochrome image, exports by laser photo-typesetting to be folded on chromatic filter layer, forms the color solid image under the irradiation of backlight.Chromatic filter layer is made of RGB optical filtering bar or the optical filtering color lump of periodic distribution, is applicable to the stereo-picture output of various breadths and pitch.
The following describes the structure of color laser phototypesetting sheet and realize the process that color laser phototypesetting is exported.
Color laser phototypesetting sheet is made of antihalation layer, sheet base, binding layer, sensitive emulsion layer, protective seam; add chromatic filter layer between sheet base and sensitive emulsion layer; sensitive emulsion layer is after the laser photocomposing machine exposure, rinsing; the black white image of record is under the backlight irradiation; through the filter action of chromatic filter layer, color display.Chromatic filter layer is made of RGB optical filtering bar or the optical filtering color lump of periodic distribution, and except three primary colors RGB, the filter pattern that also can add other color is further improved the color of image, and the present invention mainly describes the filter layer that is comprised of RGB optical filtering bar.The colorized optical filtering layer pattern by periodically, continuously apart from and the redness that is arranged in parallel consider striation (2), greenly consider striation (3) and bluely consider striation (4) formation, the width of considering striation equates, be that live width is that the red, green, blue three look optical filtering bars of w are arranged in one group of optical filtering bar that live width is 3w, N group optical filtering bar consists of whole chromatic filter layer, this design is succinctly to optimize, but is not necessary.The direction of optical filtering bar parallel with laser photo-typesetting scroll attachment direction or vertical be all feasible, but can relate to the maximum breadth of stereo-picture and with the locator meams of black white image.
The production method of chromatic filter layer can be with reference to the colored filter exposure technique of LCD panel, and cost is higher but colour filter good.Colored filter is a spare part that can not lack realizing the LCD color, in the manufacture method of colored filter, the technology of main flow is the Photoresist method of Pigments formula, this is that pigment with corpusculed is distributed in photoresist equably, with this dyeing photosensitive material, repeatedly smear on the glass substrate with Black Matrix, the processing procedures such as exposure, little shadow, to form the dye layer of RGB.Chromatic filter layer in the present invention does not need black matrix B lack Matrix, produce relatively simple, in detail can be with reference to related data.
Color sensitive lamp sheet after flushing has comprised antihalation layer, sheet base and chromatic filter layer, only needs the binding layer of continuation coating thereon, sensitive emulsion layer, protective seam to get final product.Therefore can adopt full impregnated, semi-permeable colorful sensitization lamp sheet, after the mask negative film proximity printing of colorized optical filtering layer pattern, rinsing, form antihalation layer, sheet base, chromatic filter layer, then apply binding layer, sensitive emulsion layer, protective seam.
The most economical production method of chromatic filter layer is to adopt protruding seal, UV flat stamping or gravure techniques; the optical filtering bar of chromatic filter layer is designed to pattern on the spot without the site; be printed onto on the plate substrate material of rolling with the good RGB spot ink of color developing, then carry out the subsequent coated technological processes such as antihalation layer, binding layer, sensitive emulsion layer, protective seam.
What export on color laser phototypesetting sheet is stereo-picture, R, G, B three colouring components are reassembled into a monochrome image file, the diaphanous spot of RGB sub-pixel (6) is placed in the middle, sub-pixel (6) is arranged above and below and forms a full color pixel (5), be perpendicular strip, the lateral resolution of the stereo-picture that shows after exposure is rinsed can reach the resolution of laser photocomposing machine minimum laser point.With the raster stereoscopic picture of RGB pattern, be converted into the stereo-picture of grayscale mode, and further be meshed into the method for the 1bit TIF image that can expose, but two patents that relate in the reference background technology.Contraposition requirement and Adopts measure during laser photo-typesetting output stereo-picture:
Aligning accuracy between stereo-picture and chromatic filter layer, it is different requiring on the parallel and vertical direction of optical filtering bar, less demanding with the aligning accuracy of optical filtering bar parallel direction, there is no in other words the requirement of contraposition, and have high contraposition requirement on vertical direction.If do not reach the contraposition requirement in actual production, the transition that perhaps filters between bar is not sharp keen, when excitation is not high, can increases black and block lines and guarantee the color entirely accurate between optical filtering bar of all kinds.The color gamut of gray scale stereo-picture is adjusted to 0～g from 0～255, g＜255, carrying out gridding processes, increase the isolation between the stereo-picture sub-pixel, owing to using addition colour developing principle, do like this colour vividness and the contrast that can't reduce image, just brightness slightly descends, and the brightness of corresponding increase backlight can make up.General color value adjusts to 0～150, can solve preferably the color cross-talk problem that causes not because of alignment precision.
Contraposition between stereo-picture and chromatic filter layer, most critical are also the simplest requirements, find exactly contraposition reference point or the reference edge of optical filtering bar, adjust the outgoing position of stereo-picture according to contraposition reference, guarantee both accurate contrapositions.If the optical filtering bar is vertical with spool, can utilize two edgings of color laser phototypesetting sheet to make reference edge, do not need other mark.If the optical filtering bar is parallel with spool, need to locate to stamp the equidistant perforation of series at the both sides of color laser phototypesetting sheet cross curve marks (1) and make benchmark, must guarantee all when exposing the color solid image that perforation is snapped into the fixed position at every turn.Obviously, stamp circular on the both sides of color laser phototypesetting sheet coiled material or sheet material or square contraposition perforation, perforation centre distance is the integral multiple of one group of optical filtering bar, is all effective for the contraposition of the phototypesetting sheet of any optical filtering bar direction.In addition, add the insensitive photoelectric induction device identification optical filtering bar of contrast screening sensitive emulsion layer position in laser photocomposing machine upper slice mechanism, can guarantee that also image aims at the accurate of filter layer.
The present invention is the follow-up invention of developing on the basis of patent 200710079378.5, if only be used for output color plane image, there is no other substantial meaning except density, contrast advantage.Color laser phototypesetting sheet is mainly used in the output of stereo-picture, can utilize existing laser photo-typesetting equipment to realize, the lateral resolution of stereo-picture really reaches the resolution of laser photocomposing machine minimum laser point, satisfies the production requirement of stereo lamp box sheet high precision, high colour vividness, high-level efficiency, lower cost.
