How does PS make such a fence advertisement?

Generally, PS is enough for outdoor advertising. I often do indoor and outdoor advertisements, and my friends upstairs should not do much, so there are several things that are not very correct.

First, indoor and outdoor advertisements are ink-jet printed instead of printed, so there will be no film (that is, film), so there will be no mode. For you, using CMYK and RGB mode is the same.

Second, when PS draws outdoor advertisements, the resolution does not need to be set too large. Generally, I set it to 70-90 (this is already very high, and some are set to 30-50). Because outdoor advertising is farsighted and cannot be set according to the requirements of printing, the resolution does not need to be set too much. The main reason is that the file is too large and the computer is slow to respond.

After you make the file, just export the picture in JIG format and send it to the inkjet printer. You don't need any source files (don't worry, the inkjet printer has the same effect. The source files are too big, and it will take you and the inkjet printer a long time to receive them. )

If you are afraid of blurring your own drawings, you can have a look (click the zoom tool and right-click the shortcut key "z" of print size, and you can see the print size. Check that the lower die is not blurred. If it is not blurred, there will be no problem.

In addition, if the picture is too big, it should be collaged (for example, if what you do is 8m wide and 5m high, even if what you do is on one page, the manufacturer will cut it into two pieces when you spray it, because the sprayed materials have standard specifications, and there are probably two kinds of most commonly used outdoor advertisements, namely "lamp cloth" and "outdoor glue". The former is cheap and needs to be fixed with something, such as glue or any nails around it. The latter is expensive and can be pasted. The torn back film can be directly attached to the wall with high precision and good effect.

Generally, inkjet materials are rolled up, and the length is very long, ranging from several hundred meters. Most of them are only 3 meters wide, and they are spliced over 3 meters. If it's a picture, it's better to do it together, not separately. If not, it's better to do it alone, so as to avoid the problem of crashing when the file is too large.

When it comes to margins, just measure the actual size with a ruler and print it according to the actual size, without bleeding like printing. If some outdoor advertisements need edge banding (that is, making a border around them will definitely press down a paragraph), just talk to the manufacturer and they will know to set aside a white edge of 10- 15 cm for you.

Resize and change data directly in the image-image size or canvas size.

Finally, you mentioned that white is transparent. I don't quite understand what this means. Generally, everything without content is white.

Ask me if you have any questions. .................
