I am a professional in wall advertising in Xinjiang. I have worked in various industries such as electricity, postal service, China Mobile, China Unicom, telecommunications, PICC, military insurance, life insurance, family planning, health and epidemic prevention, electric vehicles, agricultural supplies, etc. Wall advertising. Templates are mainly made from different materials based on the amount of advertising the client is doing. The premise is 1. practicality and 2. economy. The materials include iron sheet, ppc and other light and stiff materials. Generally, an engraving machine is used because it is fast and the font is accurate. If it is really inconvenient, you can also draw it on paper using a machine, and then carve it out yourself with a knife. (However, you must know how to ligature when making it yourself, otherwise it will not be possible to operate). The iron sheet uses 0.3 or 0.2 white tin plate, which is generally called tinplate. These two effects are very effective when sprayed. They can also be applied with a brush, roller or sponge. If the wall is uneven, the effect will be worse. However, you must be careful and meticulous so that you can look like a professional. Writing by hand is generally performed when the wall area is large, the number of lines is too few, and the machine is incomplete. To write by hand, you need to have some calligraphy foundation and understand the basics of wall calligraphy. The most important thing is to be serious and pay attention to details, so that even handwriting can have the same computer-stereotyped effect.
