Application of Luminescent Fluorescent Inks in Single Perspective Advertising

A single-perspective window advertisement will make it easy to see the advertisements during the daytime, but when the night falls on the earth, nothing can be seen. If you want to see the window advertisements at any time in the night, there is only one solution. It is to use luminous fluorescent ink.

Luminous ink is made of long-lasting rare earth luminescent materials and made by high-tech means. Absorb sunlight for 10-30min during the day, it will automatically continue to shine more than 10h, so it is still shining in the middle of the night, especially when the car is running in the dark, luminous and bright, eye-catching, it is similar to neon advertising, neon lights need power to shine, The luminous ink does not have to use electricity, save energy, unlimited use of recycling, can also be called solar "neon" advertising. Luminous ink is non-toxic, harmless and non-radioactive. It can last for more than 10 years. Luminous fluorescent ink can be used to print the pattern and text you need through screen printing. Design the screen to expose the luminescent layer, do not cover it all, otherwise it will reduce the luminescent effect. In addition, try to keep the customer sent the design of the original, if the ad's font is red, then in the red font printing 1.5 ~ 3cm wide luminous ink, or blue bottom dew white font, printed in the font Luminous ink is better.

The single perspective advertising process opens up new markets for screen printing, so the single perspective screen printing process is described as follows:

First, prepress preparation

1. Plastic sheet selection and discrimination

1 Polyvinyl chloride (PVC). Appearance: transparent to opaque and hard. Flammability: Flame retardant. Burning in the flame is yellow, the fire edge is green, white smoke; there is softening, can smell the burnt smell.

2 Polyethylene (PE). Appearance: Translucent to opaque, transparent film texture. Flammability: Flammable in flames. Slowly extinguish or continue burning after leaving the flame. When burning, the upper end of the flame is yellow and the lower end is blue; there is a phenomenon of melting and dripping. Can smell the smell of paraffin.

3 Polypropylene (PP), appearance and flammability with polyethylene.

4 Polyester resin (PET), Appearance: Transparent sheet. Flammability: Flammable, leaving the flame to continue burning. Flames are yellow, black smoke; slight swelling, sometimes cracking, styrene smell. The selection of materials is very important, because a single perspective advertisement cannot influence the driver's driving, so the degree of transparency is absolutely guaranteed. Here, it is recommended that the single see-through film material is preferably treated PET, which has good ink adhesion and can meet the printing requirements. At present, PET is sold in rolls and its specifications are generally 60cm wide and 500m long.

2. Select ink

There are many types of plastic inks. According to different substrates, inks suitable for the nature of the materials should be selected. Otherwise, economic losses will result. Before the formal mass production, it is necessary to do a good job of experimentation to prove which brand of ink is suitable for printing materials. Once it is completed, it should not be arbitrarily changed. If the choice of printing material is PET, then PET screen printing ink should be selected. Try to use domestic ink as much as possible to reduce the cost. The low price is favorable to the market competition.

3. Take a film, use 13-15L 50% Yin picture dot film, the size is 130 × 56cm, a sexy dot-ray version of the sun with water.

4. In order to save money without using a film, a black sticker paper is used to cut into a trapezoid and the size is 128×104×56 cm. Lighten up two pieces of oil with sexy light glue, use black ink and white ink screen respectively, or use a white paper to cut a trapezoidal pattern, place it in a moderate position on the stretched mesh frame cloth, and then use the glass plate as a bead. In the middle, in order to avoid the paper slipping on the net cloth, then use a small scraper to scrape the net sealant to the surrounding frame repeatedly, naturally drying and exposing.

Second, the printing process

The PET pieces were 30 x 60 cm in size. Clean the PET sheet with alcohol. With water-based ink, you must check the printing quality of the dots. If there are any problems, you can wash them off with fresh water and reprint the dots. The full version is printed with PET black ink and naturally dry. The full version is printed with PET white ink. White or spot color inks are printed on white ink. Last screen printing PET luminous fluorescent ink. Adhesive paper is used to tear off the water-based tearable ink. Any part that is printed with the tearable ink will become transparent. Any ink that is printed on the PET black ink will leave the ink, so that the single perspective effect is fully presented.

Third, printing experience

If there is too much ink on the PET surface during printing, the reason is that the viscosity of the ink is too high. The solutions are: reduce the pressure of the ink-covered board; increase the speed of the ink-covering board; increase the number of screen meshes; reduce the angle of ink scraping and ink coating Reduce the thickness of the template. If the surface of the PET layer is too thin, the solution is the opposite of the ones taken above.
