Detailed description of the invention
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-10, the utility model embodiment comprises:
Have a composite halftone for choana, it comprises: grenadine 1, first emulsion layer 2 and the second emulsion layer 3.
Described first emulsion layer coats end face and the bottom surface of described grenadine, and described second emulsion layer is coated on described first emulsion layer on the bottom surface of described grenadine, and described grenadine, described first emulsion layer and described second emulsion layer form half tone.
First film egative film 7 is arranged on the face that scrapes 4 of described half tone, second film egative film 9 is arranged on the printing surface 5 of described half tone, described second film egative film is actual original copy pattern, pattern on described second film egative film forms the line image of actual needs printing through printing down technique, described first film egative film is described second film egative film under the constant prerequisite of centre-to-centre spacing, generated by original image externally expanding single edge 100um.Pattern center distance on pattern center distance on described first film egative film, described second film egative film and described lines open centre are apart from being positioned on same vertical line, the diameter of the area of the pattern 8 of described first film egative film is greater than the diameter of the area of the pattern 10 of described second film egative film
Be provided with lines opening 6 in described half tone, lines latent image 601 is arranged at above grenadine, and the diameter of described lines open top face is greater than the diameter of bottom surface.
The diameter of described lines open top face is identical with the diameter of the area of the pattern of described first film egative film, or is less than the diameter of area of the pattern of described first film egative film.
The diameter of described lines opening bottom surface is identical with the diameter of the area of the pattern of described second film egative film, or is less than the diameter of area of the pattern of described second film egative film.
Have a preparation method for the composite halftone of choana, use the emulsion of two kinds of different qualities to be coated on one simultaneously and throw the net above version, its step comprises:
Half tone clean for pretreatment is put in baking oven and thoroughly dries, half tone is coated with the first emulsion layer, be then put in baking oven and dry, the first emulsion layer parcel grenadine.
After first emulsion layer drying, be coated with the second emulsion layer in printing surface direction, and the second emulsion layer is covered in above the first emulsion layer.
Put into baking oven after second emulsion layer has been coated with thoroughly to dry, repeat the second emulsion layer coating, till thickness reaches customer requirement.
The shaping of half tone image is irradiated from printing surface by ultraviolet, along with the prolongation of time for exposure, emulsion from printing surface to scrape face solidification process.When emulsion is from printing surface to after the face that scrapes is solidified completely, this time for exposure is correct exposure time of this emulsion.
One-tenth due to often kind of emulsion is grouped into different, has different characteristic.Therefore often kind of emulsion has the time for exposure correct separately.The emulsion selecting the time for exposure long is as the first emulsion layer, and the emulsion using the time for exposure short is as the second emulsion layer.
Take out the second film egative film and be positioned over printing surface direction, ultraviolet light source is injected from printing surface, by the stop of second film, makes photoresists continue to be cured from printing surface to the face of scraping, and formation finally prints lines.
First film egative film is identical figure with the second film egative film, wherein the first film egative film figure be the second film egative film figure extend out generation, larger than the second film egative film figure.
First film egative film ensure that scraping face emulsion non-lines opening part position fully solidifies, and can not affect half tone service life;
Second film egative film is formed and finally prints lines, due to the second emulsion layer and the first emulsion layer required time for exposure different, under same exposure energy, second emulsion layer completes solidification, and the first emulsion layer opening does not fully solidify, therefore funnel-form lines opening after development, simultaneously, can by the different coating thickness of adjustment first emulsion layer and the second emulsion, or dissimilar material properties, produce different choana amplitude and pattern.
