Technology always replaces things which need more human effort to do things and that’s why technology is developed to reduce human effort but it does not mean that technology can do all things by itself. It somewhere needs a human hands, a useful interfere which is necessary to be done by it.
The same thing, a useful interfere has been done in the making or process of banners or flexes. You must have seen those big banners and flexes of some products or services for advertising something hanging over a bridge or on a specialized vehicle on which they are placed. When technology was not as developed as today is, at that time the work of printing and painting were done manually and it is still done somewhere but not as much as before. Now banners and flexes are printed by a billboard printer which print at the rate of 360 dpi provided your banners have a nice and fine print and what you want to display on it look fine.
When printing was done manually those who painted they had to pay close attention because a single mistake could ruin their whole hard work and they had to start it from starting but with the help of billboard printing one does not need to be bothered much because banners are printed automatically by the printer. Technology has eased the work and reduced the human effort provided in little time many banners can be done while earlier it took a whole day.
These banners are printed on a billboard vinyl material because of its quality of endurance. This material is anti mildew, flame retardant and also UV resistant provided it cannot get damaged by heat and UV rays and also by fire. Advertising and marketing through banners is one of the old ways of promotion which is still done because if today you use digital banners there are always a worry remains with them because they can be damaged by raining or if power supply go off they become off too and if they are battery operated then you always have to change their batteries. So in all ways printed banners are useful than all others.
