Liquid photosensitive ink is a special UV ink, which can be used for full-plate printing without printing plate. After photo-curing and developing, the ink coating can be processed by etching, electroplating, electrophoretic filling, etc. It is suitable for the production of small batch, multi-variety, personalized and high-precision graphic products.
1. Liquid photosensitive resist plating ink
The liquid photosensitive resist electroplating ink is a single-component, weak alkali development, contact exposure type photosensitive ink, which has excellent acid resistance or electrical corrosion resistance. The graphic resolution is 0.03mm. It is mainly used for high precision circuit boards, Inner layer etching of laminate circuit, corrosion of various precision metal signs and electroplating printing process.
2. Liquid photosensitive gravure resist ink
Liquid photosensitive gravure resist ink is specially used for aluminum foil gravure printing, with low viscosity and good flexibility of cured film. Compared with general photoresist inks, the cured film has excellent adhesion to aluminum foil and extremely strong resistance to strong acids such as hydrochloric acid. The gravure printing speed is up to 50 ～ 100m / min, the hot air drying time is short (100 ～ 120 ℃, 5 ～ 10 minutes), if the ink viscosity is large during printing, a small amount of ethyl acetate, butyl acetate or cyclohexanone can be added for dilution .
3. Liquid acid and alkali resistant photoresist ink
The liquid acid and alkali resistant photoresist ink is specially developed for the precision aluminum sign corrosion process, and is developed with a solvent-based special developer. During etching, strong acids or bases such as hydrochloric acid and sulfuric acid can be used, such as etching with sodium hydroxide solution. After etching, sodium carbonate aqueous solution and caustic soda solution cannot be used to remove the film, because aluminum is an active amphoteric metal and is not resistant to acids and alkalis. Use organic solution to develop and remove the film. Therefore, the ink uses xylene or aromatic hydrocarbon solvent to remove the film, which has no effect on the aluminum plate.
4. Liquid photosensitive hot stamping varnish
Liquid photosensitive hot stamping varnish is a colorless transparent varnish. It is used for hot stamping of various thermal transfer foils. It has excellent photosensitive performance and high graphics resolution. It is compatible with various metals, glass, plastic films, Leather, paper, etc. have good adhesion fastness. The photosensitive film has the characteristics of high brightness, high hardness, no yellowing and scratch resistance after UV curing.
The unique feature of the new process of liquid photosensitive hot stamping varnish is: there is no need to make metal hot stamping relief, as long as there are positive negatives, it can be hot stamped. Therefore, the cost is low and the speed is fast. It is suitable for small batches and multiple varieties of personalized hot stamping The production of printed products; the hot stamping temperature is low (100 ~ 130 ℃), can be large area or fine lines of hot stamping; hot stamping substrate is not limited, you can use a variety of plastic films, paper, leather, metal, Glass, etc.
5. Liquid photosensitive metal matte ink
Liquid photosensitive metal frosted ink, also known as imitation metal etching ink, printing high-gloss metal substrates, such as mirror stainless steel, titanium gold plate and glass. The ink is colorless and translucent, using 200-300 mesh screen full-page leak printing, developed with dilute alkaline solution, the cured film has good adhesion to metal substrates, high hardness, good matte effect, and has a variety of colors.
After printing with liquid photosensitive color sand ink, the background color of the sand surface effect such as gold or silver can be obtained. No matter how fine the corrosion pattern is, the accurate sand surface background pattern can be produced. There are many colors of gold, light gold, champagne, antique copper, silver white, emerald green, black, ruby ​​red and so on. Liquid photosensitive metal anti-blasting ink is an ink specially designed for precise sandblasting patterns on glass or high-gloss substrates.
6. Liquid photosensitive solder resist ink
The liquid photosensitive solder resist ink is a two-component dilute alkaline solution developing ink, which has dual functions of photosensitive and thermal curing. Used to manufacture double-sided and multi-layer circuit board solder mask patterns. After development, the solder mask film has high brightness, hardness and adhesion, excellent thermal shock resistance, acid and alkali resistance, and solvent resistance. There are green, blue, gold, red, black and Other colors.
