John_Do is exactly correct, however, I have to ask what is the final destination of your image? If it is indeed print, then you are still fine either way. The only inconvenience is when you place your 2480x3507 (72 dpi) image in InDesign let's say, it will come in at approximately 24"x48" at 72 dpi. Now when you scale that image down to the correct size to about one-third, in essence, you now have an image at 8.26"x11.69" and 300dpi. As John said, it's a rabbit hole.
2480 / 300 = 8.26"
3507 / 300 = 11.69"
In the past, C4D hasn't always provided a proper image set to the A4 @ 300dip, but it DID provide the proper amount of pixels for you to set it right in Photoshop. I was in the graphics world back in the dark ages and it took years to master the process. Don't feel bad not understanding.
Good luck.
