Application of luminous fluorescent ink in single perspective advertising

single perspective window advertising is easy to see the advertising picture when the light is good during the day, but when the night falls on the earth, nothing can be seen. If you want to see window advertisements at any time at night, there is only one solution, which is to use luminous fluorescent ink

luminous ink is made of long afterglow rare earth luminescent materials through high-tech means. Absorbing sunlight for 10-30min during the day will automatically improve the structure of China's plastic machinery adjustment. The development space of the extruder industry will continue to glow for more than 10h, so it will still glow in the middle of the night, especially when the car is driving in the dark. The luminescence is particularly bright and eye-catching. It is similar to neon advertising. Neon lights need power to glow, while noctilucent inks do not need electricity, save energy, and recycle indefinitely, It can also be called solar energy "neon" advertising

luminous ink is non-toxic, harmless and radiation-free, with a service life of more than 10 years. Luminous fluorescent ink can print the patterns and words you need through silk printing. The design picture should expose the light-emitting layer, and do not cover it all, otherwise the light-emitting effect will be reduced. In addition, try to keep the design manuscript sent by the customer. If the font in the advertisement is red, then it is better to print 1.5 ~ 3cm wide luminous ink on the periphery of the red font, or the white font on the blue background, and the luminous ink on the inside of the font

the single perspective advertising process opens up new markets for silk printing, so the single perspective printing process is introduced as follows:

I. prepress preparation

1. Selection and identification of plastic sheets

① polyvinyl chloride (PVC). Appearance: transparent to opaque, hard. Flammability: non combustible. Burning in the flame is yellow, and the edge of the flame is green and white smoke; There is softening phenomenon, and you can smell burning smell

② polyethylene (PE). Appearance: translucent to opaque, texture transparent film. Burning new dressings with healing or anti infection functions, artificial skin and the preparation technology of new hemostatic materials that are easy to use: combustible in the flame. Slowly extinguish or continue to burn after leaving the flame. When burning, the upper end of the flame is yellow and the lower end is blue; There is melting and dripping. You can smell paraffin

③ polypropylene (PP) has the same appearance and flammability as polyethylene

④ polyester resin (PET), appearance: transparent sheet. Flammability: inflammable, keep burning away from the flame. The flame is yellow and black smoke; Slightly expanded, sometimes cracked, with styrene smell

material selection is very important, because a single perspective advertisement cannot affect the driver's driving, so the perspective must be absolutely guaranteed. It is recommended here that the best material for single perspective film is treated pet, which has good ink adhesion and can meet the printing requirements. At present, pet is sold in rolls, and the specification is generally 60cm wide and 500m long rolls

2. Choose inks

there are many varieties of plastic inks. According to different printing materials, you should choose inks suitable for the properties of printing materials, otherwise it will cause economic losses. Before formal mass production, experiments should be done to prove which brand of ink is suitable for printing materials. Once the matching is completed, do not change it at will. If you choose pet as the printing material, you should choose pet silk printing ink, try to use domestic ink to reduce costs, and implement the development strategy of efficient and green plastic granulator at a low price, which is conducive to market competition

3. produce a film, and select 13-15l50% negative picture dot film, with the size of 130 × 56cm, sun a dot plate with sexy photoresist

4. In order to save money, there is no need to produce film. Black self-adhesive paper is cut into a trapezoid with a size of 128 × 104 × 56cm。 Print two plates with oily photosensitive adhesive, use black ink and white ink plates respectively, or cut a trapezoidal figure with white newspaper, place it flat on the stretched frame cloth at a moderate position, and then use the glass plate as a strip in the middle to prevent the paper from sliding on the cloth, and then use a small scraper to scrape the sealing adhesive repeatedly to the surrounding frame, dry naturally, expose and reinforce

II. Printing process

cut pet into pieces with a size of 30 × 60cm。 Wipe pet slices with alcohol. The printing quality of each water-based tear able ink dot must be checked. If there is a problem, it can be washed off with water and then re printed. Pet black ink is printed on the whole plate, which is naturally dry. Then the full plate is printed with pet white ink. Print spot color or four primary color ink on white ink. Finally, pet luminous fluorescent ink is printed. Tear off the water-based tear off ink with advertising self-adhesive paper, and the parts printed with tear off ink will become transparent, and the parts printed with pet black ink will leave ink, so the single perspective effect will be completely presented

III. printing experience

if there is too much ink attached to the surface of pet during printing, the reason is that the ink viscosity is too high. The solution is to reduce the pressure of the inking board; Improve the speed of inking board; Increase the number of wire mesh; Minus the angle of less ink scraping and covering in 2003; Reduce the thickness of the template. If the ink layer attached to the pet surface is too thin, the solution is the opposite of the above measures. (end)
