[specific embodiment]
Case study on implementation one
Fig. 3 gives a kind of production method flow chart of negative pressure drying silk-screen halftone of the invention, and Fig. 2 gives by this hair
The structure of the negative pressure drying equipment of bright production 2,3 is illustrated with reference to the accompanying drawing:
As shown in figure 3, a kind of production method detailed process of negative pressure drying silk-screen halftone is as follows:
1) prepare the silk-screen halftone S1 to be dried of a blank attachment emulsion；2) its printing has been placed on up
The level table of the device of drying and negative pressure, heating, drying S2；3) emulsion S3 is coated in printing face；4) its printing is faced
Under be placed on drying and negative pressure device level table, to emulsion apply negative pressure, heating, drying S4；If 5) emulsion
Thickness degree is insufficient, then applies emulsion, dries S5 through step 4；6) by halftone exposure, development S6；6) it is dried again through step 4
S7。
In S1, the silk-screen halftone for selecting blank clean, first oil removing degreasing keeps the cleanliness of grenadine；It is roasting with low temperature afterwards
45-55 DEG C of case is dried for standby.
Then emulsion is coated on clean halftone, the coated area on halftone is unilateral 2cm bigger than stock.
In S2, start the infrared heating device 25 of negative pressure drying machine, after 24 temperature of level table reaches 50 DEG C, by net
23 printings of version are placed on up on the level table of negative pressure drying machine, are dried 3-5 minutes；
In S3, emulsion is coated again in 23 printing face of halftone；
In S4,23 printing of halftone is placed on down on the level table 24 of negative pressure drying machine, then there is release characteristic
Ventilating interlayer 22 be placed on 23 printing surface of halftone, after seal frame 20 is covered to and is started negative pressure device 26, coat thoughts at this time
For the grenadine of X-ray emulsion X under 21 negative pressure pressure of stripper rubber, moisture content and solvent in emulsion run through ventilating interlayer 22
It is discharged by the pipeline of negative pressure device, the emulsion after 3-4 minutes on halftone is dry to be completed, and is closed negative pressure device 26, is opened close
It seals frame 20 and takes out halftone 23.
In S5, if sensitive emulsion layer thickness not up to requires, just come again by S3-S4 one time, until emulsion thickness
Until degree reaches requirement.
In S6, emulsion will be coated with and dried halftone exposure, development.
In S7, after negative pressure drying machine level table temperature reaches 50 DEG C, 23 printing of halftone is placed on negative pressure downwards
On the level table 24 of drying machine, then there is the ventilating interlayer 22 of release characteristic to be placed on screen painting face, after by seal frame 20
It covers and starts negative pressure device 26, develop has the halftone of figure under 21 negative pressure pressure of stripper rubber at this time, on halftone, schemes
The moisture content in shape area runs through ventilating interlayer 22 and is discharged by the pipeline of negative pressure device, and halftone is dry after 8-10 minutes completes, and closes
Negative pressure device 26 opens seal frame and takes out halftone 23.
Thus the problems such as product of the screen painting of case study on implementation production, graphic edge is neat, smooth, no sawtooth, dog tooth,
It is apparent using printed pattern, accurate.Referring to attached drawing 4.
Case study on implementation two
In Fig. 3, a kind of production method process of negative pressure drying silk-screen halftone also gives second of case study on implementation, under
Face is illustrated in conjunction with attached drawing 2, Fig. 3:
The difference of the implementation case and case study on implementation one is the difference of photosensitive material, and requires no S2, S3 and S5.
In S1, the silk-screen halftone for selecting blank clean, first oil removing degreasing keeps the cleanliness of grenadine；It is roasting with low temperature afterwards
45-55 DEG C of case is dried for standby.
Then in cleaning and dried halftone, one layer of water mist is sprayed, uniformly moistens grenadine, then the net in printing face
Yarn attaches photographic film, and photographic film area is unilateral 2cm bigger than stock.
In S4, start the infrared heating device 25 of negative pressure drying machine, after 24 temperature of level table reaches 50 DEG C, by net
The printing of version 23 is placed on down on the level table 24 of negative pressure drying machine, then ventilating interlayer 22 is placed on screen painting face, after
Seal frame 20 is covered and starts negative pressure device 26, is pasted with the grenadine of photographic film at this time in 21 negative pressure pressure of stripper rubber
Under, the moisture content in photographic film runs through ventilating interlayer 22 and is discharged by the pipeline of negative pressure device, after 3-4 minutes on halftone
Photographic film is dry to be completed, and negative pressure device 26 is closed, and is opened seal frame and is taken out halftone 23.
S5 is required no, directly carries out operation by the S6 of case study on implementation one.
Thus the problems such as product of the screen painting of case study on implementation production, graphic edge is neat, smooth, no sawtooth, dog tooth,
It is apparent using printed pattern, accurate.Referring to attached drawing 4.
The halftone cross-sectional view made shown in Fig. 4 of method of the invention, from fig. 4, it can be seen that the emulsion of this halftone
Or the graphic edge of photographic film production is neat, smoothly.
Specific embodiments of the present invention are described above.It is to be appreciated that the invention is not limited to above-mentioned
Particular implementation, devices and structures not described in detail herein should be understood as gives reality with the common mode in this field
It applies；Those skilled in the art can make various deformations or amendments within the scope of the claims, this has no effect on of the invention
Substantive content.
