When creating a new print mode, you can directly select the color mode and resolution. The specific operation steps are as follows:

1, turn on PS on the computer.

2. Click File-New in the upper left corner.

3. Set the resolution to 100, and then select the color mode: CMYK color.

4. Click OK after setting.

Precautions:

Generally, the resolution of ordinary exhibition boards is 70~ 150, so it is enough to make exhibition boards with the resolution of 100.
