Description
Technical field
The present invention relates to a kind of color-painting method of digital control, the optically-variable figure that is adapted at colored drawing shades of colour figure on the various rigid and flexible materials or has the grating micro-structural.
Background technology
The colored drawing technology is widely used in the daily life, comprises printing various advertisements, print product, packaging material, and perhaps clothes in the daily life etc., in addition little of button, key chain etc.Mature methods has at present: digital ink-jet colored drawing, LASER HEAT distillation color printer etc.
Utilize ink-jet printer can realize digital coloured drawing, but its processing speed is slower, and cost is very high, particularly when handling the large format colored drawing, it is more outstanding that above-mentioned defective seems.
The course of work of laser color printer is by charging on photosensitive drums, exposure, development, image rotation, photographic fixing, removing and removes the process of seven big step cycle actions such as looking like.The concrete course of work is: at first be full of positive charge or negative electrical charge when printing beginning on photosensitive drums, and then the view data that printer processes is good sees through laser beam and shine on the photosensitive drums, and expose in the relevant position; The magnetic that contains microcapsules can have with photosensitive drums on the electric charge of same nature, the photosensitive drums that makes quick rotation is during through powder box, the part that is exposed can be adsorbed charged magnetic and video picture; When paper through the out-of-date because electric charge effect that there is a natural attraction between the sexes, make magnetic image rotation on the photosensitive drums to paper; Then by the mode photographic fixing of HTHP, magnetic closely is combined on the paper on paper; At last the magnetic on the photosensitive drums is removed, then the static on the photosensitive drums is removed, just remove picture.The pigment difference that microcapsules are contained can produce different colors.
Laser color is printed the main printing that is fit to paper material because the price of organic photo conductor drum and service life problem, the price that laser color is printed is still high, becomes the major obstacle of its application.
Summary of the invention
The object of the invention provides a kind of method of utilizing laser to realize the colored drawing of digital control, so that make the colored drawing figure and have the colored light variation image of micro nano structure on the matrix of various materials, more flexible reaching realized digital coloured drawing at low cost.
For achieving the above object, the technical solution used in the present invention is: a kind of method of laser digital coloured drawing comprises the steps:
(1) the hot transfer film that will include a kind of Information Level is fitted in by the material surface of colored drawing;
(2) utilize computer control to adjust optical head and, make the laser beam irradiation position aim at the next location of pixels of drawing by the relative position of the material of colored drawing;
(3) open laser beam, transient heating makes the Information Level of the hot transfer film on the material surface melt to come off and is adsorbed on by on the material of colored drawing, form a colored drawing unit pixel on by the material of colored drawing;
(4) according to predefined graphical pixel position data, repeating step (2) and (3) are until the drafting of finishing this kind Information Level;
(5) change the hot transfer film that includes another kind of Information Level, repeating step (1) until the drafting of finishing all Information Levels, has promptly been realized required laser digital coloured drawing to (4).
Above, can be hard material by the material of colored drawing, also can be flexible material; The optical head that gives off laser beam and by the relative motion between the colored drawing material, can be by the scan mode of optical head, perhaps place by the accurate operation of the servo platform of colored drawing material, perhaps coiling is realized by the cylinder method of operation of colored drawing material, carries out therebetween triggering laser beam output carrying out figure transfer colored drawing after the precision positioning.
In concrete operations, can be, make respectively earlier have black and cyan C, magenta M, yellow Y (or red R, green G, blue B) color layers divert film or have the Information Level divert film that micro nano structure light becomes figure, three color pixel pattern-transferringlayer layer are transferred to needs be formed color graphics on the substrate surface of colored drawing with black and C, M, Y (or R, G, B) one by one to adopt laser pulse instant melting mode again.Because base material fixes, the multilayer divert film is replaceable, and it repeats the prize precision of drawing shape of digital process that shifts and depends on the positioning accuracy of laser transfer equipment.
In the technique scheme, described hot transfer film is a sandwich construction, by outside to inside comprising substrate layer, release layer, Information Level and hot melt adhesive layer.Substrate layer is the clear PET film, and hot melt adhesive layer is selected the material of strong adhesion according to the material of substrate.
Wherein, described Information Level is a color layers, comprises 3 kinds of hot transfer films at least, and it is red, green and blue that its color layers is respectively.
Perhaps, described Information Level is a color layers, comprises 4 kinds of hot transfer films at least, and its color layers is respectively cyan, magenta, yellow and black.
Perhaps, described Information Level is made of micro nano structure and metallic reflector, and micro nano structure wherein is the embossment phase structure.
Described micro nano structure is the optically-variable figure that optical grating construction constitutes.
In the technique scheme, the instantaneously heated temperature of laser beam is between 120～150 ℃ in the described step (3).Because the effect of release layer, Information Level separates with base film, and adhesive linkage is adsorbed on and is formed digital laser colored drawing figure on the colored drawing material.
Described laser beam send by solid semiconductor pump laser with 20ns～80ns pulse width after collimate, shaping obtains, laser beam wavelength is 355nm, 532nm or 1064nm.
In the described step (3) yardstick of colored drawing unit pixel at 5um between the 160um.
The method of technique scheme is applicable to that plate laser process equipment and drum-type laser shift process equipment.
Because the technique scheme utilization, the present invention compared with prior art has following advantage:
1. the difference of this method and traditional gilding technology is to have very strong flexibility.Gilding technology is at first to carry out gold stamping die head, make the graphical information on the plural layers transfer on the material by heating gold stamping die head, what a die head each figure all must do in advance like this, and the figure aligning accuracy on die head and the material requires very high, otherwise brings the figure of transferring on the material not to be sufficiently complete and to misplace.This invention is by the mode of point by point scanning line by line, according to predefined image request, makes that the film color is complete accurately to transfer on the material.
2. this method has control flexibly, and pattern precision height, colored drawing are effective, especially can go out to have the advantages such as optically-variable figure of metal-like by colored drawing, is fit to digital printing, digital laser colored drawing false proof and textile industry is used.
3. distribute by the micro nano structure that changes Information Level, the present invention can make the light variation image with colored drawing effect, has dynamic effect.
4. base material of the present invention can be paper, also can be plastics, metal and glass.
5. the equipment positioning accuracy can be accomplished 1um or higher, and by Digital Control, graphic designs and colored drawing are flexible.
