Description

A kind of method for making of photo certificate card

The present invention relates to plastics is the card card of taking pictures of base material, and being specially with PVC is the card card of taking pictures of base material.

With the card of various plastic sheet materials, its range of application is increasingly extensive, wherein needs to encapsulate or print the certificate card of individual photo, and (being called for short the picture card), as employee's card, I.D., temporary residency card, pass or the like, demand is also more and more; Card require is printed exquisite, especially required clear, the wear-resisting wiping of photograph image, rub, the operating period is long etc.; In addition, because these cards also have and can add other functions: as adding magnetic stripe, IC chip, bar code etc., also come into one's own and welcome with regard to having become to store the novel card of bulk information, and eliminated gradually original old-fashioned the sort of behind printing, paste picture on the paper certificate card of plastic packaging.Making the processing of photo on the certificate card at present, is two kinds of methods basically; A kind of is the photo inlaying process, uses in the 3-layer PET transparent plastic material and two-layer PET transparent material to be base-material, the appropriate location of in the upper strata, expecting in advance die-cut one with the big or small identical square groove of photo, after photo posted, surface coating was heated to add and is pressed into; The picture card that this method is made, process velocity is fast, service time is long, can reach decades, day output can reach several ten thousand to hundreds of thousands spare, and shortcoming is that required PET transparent plastic price is higher, manufacture craft needs complex apparatus, thereby required investment is big, makes the cost height of picture card, is applicable to the big and long-lived picture blocking work of this class amount of I.D..Another kind method is an impact system, is base material with the PVC plastics, at first photo is scanned on scanner, carries out colour-separation drafting on computer screen, is turned into electronic signal computer floppy disk again, and with this floppy disk input color card card machine (FARGO machine), individual is printed as photo.The advantage of this method is can field fabrication, is suitable for various conventions, as the card card center of the Asian Games, the Olympic Games etc., and the preparation digital camera, shooting at that time, the direct input color card of MO floppy disk card machine, individual processing, a few minutes can go out the finished product card.But adopt this method, the costing an arm and a leg of four looks that consumed (red, yellow, blue, black) colour band and printhead handled photo in batch, and print speed is slow; Because four color ribbon is after imaging on the PVC card base, colour band itself has the thick plastic foil of 8um to stick on the card surface to shield, and this tunic is too thin, and serviceable life is not long, can only use 2-3 usually.The disposal route of above-mentioned two kinds of photos, complex process, wherein a kind of manufacturing speed is slow, the cost height, seriously restricting this is being extensive use of of novel card card of base material with plastics.

Purpose of the present invention, providing the plastics that a kind of technology is easy, quick, equipment investment is few, cost of manufacture is low is the method for making of the photo card card of base material.

The method of making photo certificate card of the present invention is to have adopted photo is carried out pretreated interior imaging method, and its concrete processing step is as follows:

The pre-service of photo: separate easily with the photo surface layer for impelling the photo base stock, and obtain complete photo surface layer, photo is carried out pre-service;

(1) at first mixes for 1 part with 25 ℃-35 ℃ water and stir evenly, make and discongest slurries by weight the cellulase 2-1 part that with activity is 500-1000;

(2) will discongest slurries by 1: 100 (weight ratio) and mix with 35 ℃-45 ℃ water, and stir, it is 7.8 that the repeated hydrogenation sodium oxide molybdena is transferred pH value, is mixed with and discongests liquid;

(3) soak 24 hour or more above-mentioned discongesting in the liquid black and white or photochrome;

(4) the photo surface layer after carefully will soaking is torn, and discards base stock, keep the surface layer of tearing and answer zero defect, its surface thickness should≤0.08mm, then 80 ℃-100 ℃ dry 20-25 minute, and press multiple smooth, standby;

2, the stickup of photo: super glue is coated at the photo surface layer back side that drying flattens, sticked on through on the reserved location of expecting among the PVC after the conventional printing process processing of fabrication, the thickness of middle material is 0.3mm;

3, the pre-service of upper and lower two-layer facial mask: at thickness is the transparent PVC facial mask surface of 0.06-0.1mm, evenly applies 135 thick type resins of 0.04-0.06mm, then at 40 ℃-45 ℃, solidifies and makes glue PVC film in 20-30 minute, standby;

4, material among the PVC that 0.3mm is thick, post among the PVC of same thickness of photo material and through pretreated upper and lower facial mask totally four layers in mirror board the manufacturing card with routine synthesize, the aniseed after synthetic blocks through dashing, make finished product after the product examine.

Described seccotine is the moment seccotine, and 135 type resins claim water base lamination oil again, and the pretreatment process of above-mentioned facial mask is prepared glue PVC facial mask, also can directly replace with the glue PVC film of buying from the market that has.

It is simple that the photo disposal route of plastics card card of the present invention has manufacture craft, quick and convenient and have an advantage of photo inlaying process, but large-scale mass production, photo is handled attenuation, solved and card basic strong bond and surface-brightening, smooth technological difficulties, still use original printing and synthetic, die cutting device, need not to increase more equipment.Therefore, equipment investment is few, cost is low, and the sharpness of photo and scuff resistance be also significantly better than impact system, the photo after handling with this method, and aliquation, non-foaming, eclipsed has not kept the sharpness of photo fully.

Example 1

Extracting cellulose enzyme (activity: 1000, buy by the food additives shop) 150g, join in the water of the 300g about 30 ℃, be mixed into even paste liquid, again this pulpous state liquid is added in the 4500g warm water about 40 ℃, after mix stirring all, add 2.25gNaOH (chemical pure), be mixed with pH value and be 7.8 to discongest liquid standby;

The photo of fabrication is separated in duplicate (reservation is a, replaces during in order to damage and uses), get a photo and cut into the identical size of 1 inch, be immersed in and be equipped with in the shallow vinyl disc of discongesting liquid, photo faces up, can not adhesion between photo, soak after 24 hours, individual takes the photograph the son base stock of tearing with tack, stay the photo surface layer, be placed on the stainless steel flat plate, in baking oven, dried by the fire 20 minutes with 120 ℃, then, they calm down in two glass plates press multiple 4 hours standby;

The processing of the upper and lower aspect film of picture card:

With two layers of thickness be the transparent PVC film of 0.08mm respectively on screen printer, with the 135 type resins (also claim water base lamination oil, buy) of 200 order gauze blade coating 0.05mm thickness, solidified 20 minutes at 45 ℃ by the chemical products shop, make the sticky surface film;

The photo surface layer back side that flattens sticked among the thick PVC of 0.3mm that fabrication operation routinely prints with moment seccotine (there is the production of capable enterprise-like corporation in Zhuhai, Guangzhou) expect reserved location, bondline thickness should be not more than 5 μ;

At last, with material (wherein material has pasted photo in one deck) among the upper and lower aspect film handled well, the PVC that two layers of thickness is 0.3mm, totally four layers of sign indicating number are neat, and last laminating machine (Taiwan: AZ450), at 125 ℃, under the 25kg pressure, blocked in per 23 minutes synthetic one by big opening; The synthetic every big card (48) of opening is through die-cut, and seal is finished product after the product examine; 1000 on daily output picture card.
