Abstract
The present invention discloses a method for making a relief printing plate without using photography devices, etc. The present invention is particularly suitable for medium and small-sized printing houses. A negative film is made in a darkroom, ink draft and the film are clamped by glass plates, and the ink draft is exposed upward to carry out development and fixation. After the negative film is made, the negative film carries out trimming and plate burning, and the film and a solid photosensitive resin plate are clamped together to be sunned for 2 minutes to 5 minutes, and then, the film is removed. After the resin plate carries out sensitization, the resin plate is put in warm water to be washed by a hair brush, and the relief printing plate is made after the resin plate is baked.
Description
The present invention relates to a kind of method of making block of equipment such as need not take a picture, special being fit in addition, belong to printing photomechanical production field in sub middle-size and small-size printing house.
Printing is at present made block and will be passed through color rendering original text, draft, photograph, wash, boil photoresists, gluing, printing down, colour-separation drafting, corrosion etc. ten and come procedure, equipment needed thereby is many and complicated, promptly make metallograph, camera, printer, gluing dryer, thermostatic drying chamber, etching machine, to use nitric acid, hydrochloric acid and some poisonous medicines aborning, not only influence operator's health, and cause certain environmental pollution, the plate-making cycle is long, the cost height, generally take 5-10 days, can not adapt to short urgent document or dispatch of print cycle, also inconvenient for medium and small factory.
The objective of the invention is to overcome above-mentioned weak point of the prior art and provide a kind of technology simple, do not need any equipment, plate-making is fast, is fit to the method for the making block of middle-size and small-size printing house.
The object of the present invention is achieved like this: it comprises the making of egative film → repair sheet → printing down → wash technologies such as version → drying, it is without camera installation, making egative film carries out in the darkroom, cut film according to draft, film and draft are clamped with glass plate, draft upwards, open bulb and carry out exposure, put into developer solution after the exposure and develop, water flushing again, photographic fixing, washing is taken out to dry and is made workprint, repair sheet again, monochromatic living-article is repaiied the shakeout eye with prepared Chinese ink, and colored living-article will contrast color original text and carry out color separation, repairs by different colours, make monochrome film, in order to plate-making, the relief printing plate material is the solid photopolymer plate, gets the resin plate that is slightly larger than film, film is closely contacted with resin bed, clamp with glass plate then, be placed on and tanned by the sun under the sunlight 2-5 minute, remove film after the printing down, wash version, the warm water that resin plate after the sensitization is put into 25-35 ℃ is scrubbed with hairbrush, reaches till the desired depth, exposes after the drying again and promptly makes block in 2-3 minute.
Purpose of the present invention can also reach by following measure: at night of no sunlight or overcast and rainyly can adopt the ultraviolet light source printing down when needing printing down, dressing up a row with five of agricultural black light tubes gets final product, making block draft and product with this side is 1: 1 ratio, and draft can not amplify or dwindle.
The present invention has following advantage compared to existing technology:
1, whole mask-making technology does not need specialized equipment, and technology is simple, and the middle-size and small-size printing house that generally lacks of capital all can be adopted;
2, do not use nitric acid, hydrochloric acid and poisonous medicine, useful workers ' health, non-environmental-pollution;
3, plate-making cycle weak point, the not enough making that just can finish relief printing plate half a day, and also cost is low, and the press resistance rate height is so anxious living-article alive, that the seal amount is big is the most suitable with this technology.
Below in conjunction with embodiment in detail the present invention is described in detail: the first step, the making of egative film: making egative film needs to carry out in the darkroom, adorn a red light and common 15 watts of incandescent lamps in the darkroom, get qualified plate-making draft (1: 1 ratio), cut film by living-article, film is larger than living-article, film and draft are clamped with glass plate, clip with clip, draft is upwards opened 15 watts of bulbs and is exposed, general 3-5 is about second, visual draft quality and living-article require to prolong or shorten the time shutter, turn off the light after the exposure to take off film and put into the good developer solution of configured in advance and developed water flushing then 2 minutes, photographic fixing is washed to take out to dry in 10 minutes again and is promptly made egative film; Second one, repair film:,, wherein each look all repaired produce monochrome film, in order to plate-making if colored (chromatography) living-article will contrast color original text and carry out color separation if monochromatic living-article repaiies the shakeout eye with prepared Chinese ink and get final product; In the 3rd step, printing down: the printing down method has two kinds, a kind ofly uses the natural light printing down, a kind ofly use the ultraviolet light source printing down, diaphragm is taken off, evenly coated a small amount of talcum powder, to prevent egative film and plate adhesion, film closely contacts with resin bed, can not there be bubble the centre, clamps with glass plate, is placed on (or under ultraviolet light source) exposure under the sunlight, get final product following 5 minutes of ultraviolet light source general 2 minutes summers; In the 4th step, wash version: remove film after the printing down, the warm water of putting into about 30 ℃ is washed, and scrubs with hairbrush, general about 5 minutes, reaches the requirement degree of depth and gets final product; In the 5th step, drying: the version after washing is inhaled the moisture content on version surface with sponge and is gone, and carries out drying, and baking temperature is warming up to 80 ℃ gradually by 50 ℃, and about 20 minutes, expose again after the taking-up and solidified in 3 minutes, whole block is made, and printing promptly is available on the machine.
Developer formula:
Mitouer 1g, sodium sulphite 80g, hydroquinone 9g, sodium carbonate 35g,
Potassium bromide 5-10g, water 1000cc
The stop bath prescription:
Dodium thiosulfate 25-40g, water 1000cc
Claims (3)
1, a kind of method of making block, comprise egative film making, repair sheet, wash edition technology, it is characterized in that:
A, making egative film carry out in the darkroom, cut graphic arts film according to draft, and film and draft are clamped with glass plate, and draft is upwards opened bulb and exposed, and put into developer solution after the exposure and develop, and water washes, formalizes, washes to take out and dry again;
B, repair film: monochromatic living-article is repaiied the shakeout eye with prepared Chinese ink, and colored living-article will contrast color original text and carry out color separation, repairs by different colours, makes monochrome film, in order to plate-making;
C, printing down: the relief printing plate material is the solid photopolymer plate, gets the resin plate greater than film, and film is closely contacted with resin bed, clamps with glass plate then, is placed on and tans by the sun under the sunlight 2-5 minute;
