What kind of self-adhesive printer was used to print the shocking slogans affixed to the rear of the car?

Ordinary home and office printers are not suitable. The ink is not resistant to ultraviolet rays, and it is also afraid of water. You can use a process called "big car stickers". Many advertisements on buses use "big car stickers". They use outdoor inkjet ink, which is not afraid of light or water. The self-adhesive material has a certain degree of elasticity and is suitable for certain people. For some uneven car surfaces, scissors can be used to trim the special shapes after the painting is completed. The cost is not high, the market price in Qingdao is 25-45 yuan/square meter, and the graphics can be designed by yourself. The recommended resolution is 50dpi or above, not higher than 72dpi. This process is available in inkjet printing companies with a slightly larger scale - note: it is inkjet printing, not a photo! Hope this helps!
