For outdoor advertisements around 3m * 3m, how big should cdr be introduced to avoid ambiguity?
According to the distance between your audience and the advertisement, the best viewing distance of the general image is five times the height of the image. However, the minimum resolution angle that human eyes can distinguish under the condition of medium brightness is 1.5'. It is equivalent to 8DPI, but we usually use 36DPI, and the limit is 18DPI, so the minimum pixel of the whole picture is 2 126X2 126.
However, if you watch at a distance of about 1 m, it is recommended to use the resolution of 150DPI, with a minimum of 36DPI.
