The single-perspective window advertisement makes it easy to see the advertisement screen when the light is good during the day, but when the night falls to the earth, nothing can be seen. If you want to see the window advertisement at any time in the night, there is only one solution, that is, using luminous fluorescent ink.
Luminous inks are made from high-tech means using long-lasting rare earth luminescent materials. In the daytime, after absorbing sunlight for 10-30min, it will continue to illuminate for more than 10h, so it will still shine in the middle of the night, especially when the car is in the dark, the light is especially bright and eye-catching, it is like a neon sign, neon needs power to shine. The luminous ink does not need electricity, saves energy, and is used indefinitely. It can also be called solar "neon" advertising. Luminous ink is non-toxic, non-radiating and has a life span of more than 10 years. Luminous fluorescent ink can be printed on screen to print the patterns and text you need. The design screen should expose the luminescent layer, not all of it, otherwise it will reduce the illuminating effect. In addition, try to keep the customer to send the design manuscript. If the font in the advertisement is red, then print a 1.5~3cm wide luminous ink on the periphery of the red font, or a blue dew white font, and print it in the font. Luminous inks work better.
The single perspective advertising process opens up a new market for screen printing, so the single perspective screen printing process is introduced as follows:
First, prepress preparation
1. Selection and identification of plastic sheets
1.1 Polyvinyl chloride (PVC). Appearance: transparent to opaque, hard. Flammability: flame retardant. Burning in the flame is yellow, the edge of the flame is green, white smoke; there is a softening phenomenon, which can smell the paste.
1.2 Polyethylene (PE). Appearance: Translucent to opaque, transparent film. Flammability: flammable in flames. 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. Can smell the smell of paraffin.
1.3 polypropylene (PP), appearance and flammability with polyethylene.
1.4 polyester resin (PET), appearance: transparent sheet. Flammability: flammable, leaving the flame to continue burning. The flame is yellow, black smoke; slightly inflated, sometimes cracked, with a styrene smell. The selection of materials is very important, because the single perspective advertisement can not affect the driver's driving, so the perspective is absolutely guaranteed. It is recommended that the single-perspective film material is preferably treated PET, which has good ink adhesion and can meet printing requirements. Currently, PET is marketed in rolls, and the specifications are generally 60cm wide and 500m long.
2. Select ink
There are many varieties of plastic inks. According to different printing materials, inks suitable for the properties of printed materials should be selected, otherwise economic losses will occur. Before the official mass production, the experimental work should be done to prove which brand of ink is suitable for printing on printed materials. Once the package is completed, do not change it at will. If the printing material is PET, then PET screen printing ink should be selected. Try to use domestic ink to reduce the cost. The low price is conducive to market competition.
3. Take out a film, use 13-15L50% negative picture dot film, the size is 130×56cm, and use a sexy light glue to make a dot version.
4. In order to save money, no film is produced, and the black self-adhesive paper is cut into a trapezoidal shape, and the size is 128×104×56 cm. Apply two pieces of oil-sensitive photo-adhesive tape, use black ink and white ink screen respectively, or cut a trapezoidal figure with white newspaper, lay it flat on the stretched mesh frame cloth, and use the glass plate as the bead In the middle, in order to prevent the paper sheet from sliding on the mesh cloth, the sealing glue is repeatedly scraped to the surrounding frame with a small scraper, and naturally dried and exposed.
Second, the printing process
The PET piece was cut to a size of 30 x 60 cm. Wipe the PET sheet with alcohol. Use water-based tearable ink to print the dots. Each sheet must be checked for the quality of the dot printing. If there is any problem, wash it off with water and reprint the dot. The full version is printed with PET black ink and is naturally dry. The full version is printed with PET white ink. Print a spot color or a four-primary ink on a white ink. Finally, screen printing PET luminous fluorescent ink. The water-repellent ink is torn off by advertising self-adhesive paper. Any part printed with tearable ink will become transparent. Any part printed with PET black ink will leave ink, so that the single perspective effect will be fully presented.
Third, printing experience
If there is too much ink on the surface of PET during printing, the reason is that the viscosity of the ink is too high. The solution is to reduce the pressure of the ink-coated board; increase the speed of the ink-coated board; increase the mesh size; reduce the angle of ink-scraping and over-inking. Reduce the thickness of the stencil. If the PET layer is too thin to adhere to the ink surface, the solution is the opposite of the measures taken above.
