In what resolution to make a prototype of outdoor advertising?

Question

Design

At what resolution should I create outdoor advertising in Ps in order to get a clear image when printed?

Answer 1

I recommend that you clarify this issue with the printing house in which you will print the advertisement. Also, on the sites of printing houses, they usually lay out requirements for layouts, which will also be useful to familiarize yourself with.

Answer 2

Depends on the size of the outdoor. I vary the resolution for different works from 72 to 300 dpi. If possible, do it with vector tools in the same Photoshop: text, shapes, gradients. So you will not have problems with psd scaling when printing.

Answer 3

In fact, it all depends on where it will hang, you need to find a compromise between minimizing the file size and so that the viewer does not notice compression or soap artifacts. The ideal option, as already mentioned, is a completely vector layout so that it does not depend on dpi at all, but if a raster is used, then in many cases one should not be afraid of low dpi, especially in the case of 5x15 supersites, which are usually located at a height of 30 meters, for which 30 dpi is often sufficient. For 3x6 billboards, which tend to be at a fairly low height, I use around 100 dpi.
300 dpi is a value accepted by many beyond the border above which, upon close examination, the viewer will not see the difference, I definitely can’t distinguish 300dpi from 1200dpi in a photo, this can only be noticeable in very small text. That is, it is worth using 300dpi only for posters at bus stops, which the viewer can come close to and look at.
Well, as already mentioned, you should not make files with dpi higher than the capabilities of printing equipment, it makes no sense
