Description
One, technical field
A kind of have the method for the colored intaglio fine pattern of photo effect at glass and glass article surface formation.The present invention relates to a kind of digital spray printing equipment of using and form the color negative pattern at glass and glasswork (hereinafter to be referred as glass) surface, carry out chemical surface treatment then, make glass surface produce the intaglio point, at the colored erect image pattern of intaglio position spray printing, make glass surface form the method for colored intaglio fine pattern then with photo effect.
Two, technical background
Form the so-called art glass of various patterns at glass surface, in fields such as building, decoration, furniture, daily necessities, artwork, more and more used in recent years.The manufacture method of art glass mainly contains multicolor printing method, etch printing method, sand-blast, frosted method, mill method at quarter, the color brilliant method of upright line etc. at present.In these methods, because the restriction of complete processing, the pattern of processing mostly is rough strip and block structure greatly, and the shade of grey and tonal variation that pattern is shown as photo almost are impossible, thereby make the artistic expression of art glass and infectivity be subjected to very big influence.
For addressing this problem, publication number provides a kind of method at glass and glass article surface formation fine pattern for the patent of CN1446703A.Can form at glass surface in this way and have the shade of grey of photo effect and the fine pattern of tonal variation.But this pattern is a simulation black and white formula, even filling colored ink in the intaglio point after chemical treatment also can only form the pattern of single color, can not satisfy the hope that modern people require real multi color pattern.
As is generally known in the typography, colored fine pattern forms by blue or green, pinkish red, yellow, black four color separation version intussusception printings on common paper.Will be in this method of application on glass, no matter, the difficulty that can't overcome is arranged all at present on the technology or on the equipment.But the new situation that colored fine pattern is manufactured has been started in the development of digital technology.Digital-code printer or digit inkjet printer can be made multi color pattern easily on common printing circle matter, comprise photochrome.Yet with common digital technology the firm colored fine pattern of formation on glass be still the difficulty.This is because glass is a kind of surface smoothing, solid inorganic materials.The bonding force of oiliness that Numerical Control Printer is used or water-based paint or dye ink and glass is very poor, and pattern adheres to not firm, sometimes even can not form pattern.Glass surface roughened (as sandblast) and use ink special, though can improve bonding force, degree is limited, and makes the gelatinization of fine pattern film before spray printing, and deleterious lacks practicality.
The glass to photosensitive pattern is arranged that the CN1446703A patent proposes carries out chemical intaglio to be handled, and can form the small intaglio point consistent with the shade of grey, the tone of pattern at glass surface.Facts have proved in these intaglio points and insert printing ink, solidify the back,, can stand daily working conditions so adhere to very firmly because the printing ink point is embedded in the glass surface.
If utilize the digital spray printing technology to form the principle of colored fine pattern, utilize chemically treated technology to form and colored fine pattern color, level, the consistent small intaglio point of tone again at glass surface, with the digital spray printing technology colored ink is sprayed in the corresponding small intaglio point then, it is fully possible forming the colored intaglio fine pattern with practicality at glass surface so.
The present invention is exactly a kind of method of utilizing digital spray printing technology and chemical surface treatment technology to form the colored intaglio fine pattern with photo effect at glass surface of finishing according to above-mentioned imagination.
Two, summary of the invention
Provided by the present inventionly form the method for colored intaglio fine pattern at glass surface, comprise following several steps: (1) makes digital document image to the coloured image original copy with digital recording device.(2) use the raster image processor screening.(3) form the color negative pattern that constitutes by spray printing printing ink at glass surface with number agate spray printing equipment.(4) glass that the surface is had a color negative pattern carries out chemical intaglio and handles.(5) remove residual printing ink, cleaning, the drying of glass surface.(6) use digital spray printing equipment at the colored erect image pattern of former negative-appearing image pattern spray printing position spray printing.
The advantage that forms the method for colored intaglio fine pattern at glass surface provided by the present invention is: (1) can verily duplicate original copy at the color and the shade of grey of glass surface well reproduced colored original image.(2) observe from the spray printing glass back, the bright especially bright-coloured and adhere firmly of pattern color adapts to daily working conditions.(3) be fit to mechanize, mass production.(4) no egative film does not have forme, low processing cost.
Below, according to above-mentioned procedure of processing, content of the present invention is elaborated:
(1) colored original is made digital document image with digital recording device.
Digital recording device refers to scanner, digital camera, computer and corresponding software.Colored original is put into scanner (or take with digital camera) input computer, make amendment, edit and make the iamge description file with image processing software, graphics software, software for composing etc.
Continuously transferring, the original image of shade stepless transition and variation becomes the digital picture that the discrete point by three kinds of colors of red, green, blue constitutes to scanner by photo-electric conversion element, finishes the color separation processing of image.The optical resolution of scanner is high more, and the picture quality of scanning is good more, and the multiple that can amplify original copy simultaneously is big more.The bit depth of scanner and color depth are big more, and image detail that can scan and number of colours are many more.
The digital picture of scanner or digital camera output is reduced into coloured image, to edit and to revise on the indicating meter of computer.The editor of image and modification are undertaken by software.Image processing software (as Photoshop) can require to carry out picture size, color, level, the processing of sharpness etc. according to spray printing.Graphics software (as Freehand) can add processing such as geometricdrawing, input characters, copy editor.Page software for composing (as Pagemaker) can carry out processing such as image mixed character typeset.Image after edit-modify is finalized a text generates iamge description file-PS file by the print driver of supporting PDL (as the Postscript language), files.The concrete operations that original image is made digital document, can be undertaken by the digital plate-making of specialty company usually, can guarantee the quality of the multi color pattern that duplicates like this.
(2) use the raster image processor screening.
As is generally known, printing dot reproduction image, its primary image unit is a bianry image.Therefore before carrying out spray printing, to be converted into the information of image the site of two-value, form the two-value dot matrix image.Common this conversion task is finished by raster image processor (RIP).
Raster image processor also is a kind of software, be installed in computer that Numerical Control Printer links to each other on.Raster image processor is accepted the PS file that sended over by application program, and image is made an explanation and forms the site.
According to the difference that forms the site method, two kinds of am screening and fm screenings are arranged for the mode of image screening.The present invention adopts the am screening mode.The screen density of am screening (line/time) has 60,80,100,120,133,150,175 and 200 etc. eight kinds.Screen frequency is high more, and the half tone image of demonstration is meticulous more, and level is abundant more.But digital spray printing equipment has the restriction in (point/time) of equipment records resolving power.For satisfying the requirement (100 grade) of human eye to the grey scale explanation, for certain spray printing equipment, screen frequency should approach 1/9.95th of equipment records resolving power.For example log resolution be 1200 points/time Numerical Control Printer, screen frequency should be 120 lines/time.Common 120 line screenings can fully manifest the photo effect of image.
That the dot shape of screening has is square, circle and rhombus.Image contrast is big, uses square and circular usually; Image contrast is little, and soft (as character image) uses rhombus.
The color form of PS file is red, green, blue (RGB) form.The color form of Numerical Control Printer is blue or green, pinkish red, yellow, black (CMYK) this common color print format.Raster image processor also has the automatic color separation function, can be automatically color conversion be can spray printing the CMYK form.The moire that produces when eliminating four look site double exposures, site angle yellow, pinkish red, blue or green, black four looks should be taken as 90 °, 15 °, 75 °, 45 °.
Image file after raster image processor is handled will generate a negative-appearing image file opposite with the erect image file by positive and negative image transformation circuit.Positive and negative picture file can directly be imported the amplitude modulation halftone dot image of digital spray printing machine controller spray printing erect image or the amplitude modulation halftone dot image of negative-appearing image in contrast.
(3) form the color negative pattern with digital spray printing equipment at glass surface.
The used digital spray printing equipment of the present invention is flat Numerical Control Printer.Because have only flat Numerical Control Printer just can carry out spray printing at surface of plate glass.
The used spray printing printing ink of the present invention is ultraviolet photo-curing printing ink.This printing ink solidifies under uviolizing rapidly, can and have certain for fastness at formation pattern on glass.Flat Numerical Control Printer has UV irradiation equipment usually.
Under suitable screen angle, blue or green, pinkish red, yellow, black four look sites can form a kind of evenly dense rose-shaped distribution at spray printing behind glass surface.Around each color dot is that barren does not have ink area.This is the situation of erect image spray printing.When the spray printing negative-appearing image, situation is opposite, and originally barren does not have ink area at this moment by the covering of printing ink point, and color dot district originally then becomes barren does not have ink area.This has created condition with regard to carry out these color dot districts of chemical surface treatment etching for next step.Based on this principle, the present invention adopts Numerical Control Printer to form the color negative pattern that is made of light-curable ink at glass surface earlier, and the position that needs is kept the glass original surface hides, and needs is carried out the position of chemical surface treatment and vacates.
For improving the tolerance of light-curable ink in chemical surface treatment, the present invention carries out post bake to the glass that is sprayed with the color negative pattern and handles, promptly be placed on and dry by the fire certain hour in the baking oven, concrete treatment temp will be given the experiment of being equipped with property with the time to different ultraviolet photo-curing printing ink and be determined.
(4) chemical surface treatment.
Chemical surface treatment of the present invention is the glass behind the post bake to be immersed in carry out the intaglio processing in the glass intaglio liquid.
The intaglio point that intaglio handle to form is should the degree of depth darker, and the intaglio face is smooth smooth.The colored erect image pattern that becomes of spray printing like this, from glass back, because the optically focused effect of glass concave point, the color that seems is bright, bright-coloured especially.Because the printing ink point of spray printing system is embedded in the glass surface, so attachment fastness is also big.
The used glass intaglio liquid of the present invention is aqueous hydrofluoric acid containing solution.
(4) striping.
After the chemical surface treatment, the negative-appearing image ink lay is ineffective, should give removal to expose following glass original surface.Ultraviolet photo-curing printing ink usually can be in 5% aqueous sodium hydroxide solution more than 50 ℃ striping.Improve the striping liquid temp and can more effectively improve striping efficient usually than improving striping liquid concentration.
Behind the striping, clean, drying enters next procedure.
(5) the colored erect image pattern of spray printing.
Glass behind the striping is placed on the digital flat spray printing machine platform, and accurately the back, location is at the colored erect image pattern of former negative-appearing image spray printing position spray printing ultraviolet photo-curing printing ink.The erect image ink dot of spray printing is just in time beaten on the small intaglio point that forms through intaglio, because flat Numerical Control Printer promptly provides uviolizing to ink dot in spray printing, so the printing ink in the intaglio point solidifies immediately.So just formed colored intaglio fine pattern with photo effect at glass surface.
In above-mentioned procedure of processing, change or flexible technology and obtain the manufacture method of derivatives, also belong to content of the present invention:
