When rendering I am not sure how to export print-quality images that are 300 dpi or more. Is this possible to alter in the render settings somehow, or can this only be done in an application such as Photoshop?

A rendered image will come out in screen resolution, so it’s easy to do the math for a 300dpi image.
Or ‘fake’ it in Photoshop by changing the dpi value to 300.
It’s an arbitrary value anyway.

use this formula:
Height * Number of DPI for print / 2.45
Lenght * Number of DPI for print / 2.45
So for example if you want a printable panel of 70 x 100 cm usually print goes at 300 DPI then:
70 * 300 / 2.45 = 8571 Px
100 * 300 / 2.45 = 12244 Px
So, to render out an image that will get printed on a 70 x 100 cm panel at 300 DPI
you need to output a 8571 x 12244 Pixel image if you dont want any data loss and be the most precise man in the world.
Usually you can go with 150 DPI for printing high res images since those gonna be watched in a long distance. You can go even lower for big adv panels and go down at 72 dpi.

I thin it’s best explanation… good job keep it up.
