24x36-is 300dpi necessary?

[Tbonz]

Title says it all, I may have to render an image to be printable @ 24x36 inches(and some smaller sizes as well) is 300 dpi too much?

That would be 7200x10800 for the 24x36

[Chad Warner]

I would say that it's overkill, but not terribly out of the question. 24x36 is generally better off at 150 or 200 dpi.

This is just my personal opinion... but... you really should not need anything bigger than a 4k image in general. Think of it this way. Imax, which is projected on a screen that is 6 stories tall, is rendered at 4k (4000 x 3000). If you are concerned about pixelation. There are some tricks that you can do to make it look more "real." Add a very slight gaussian blur to your whole image. Like a one pixel blur or less, then add a slight film grain. It will then look like a blown up photograph and less like an pin sharp CG image.

I've had 24x36 boards printed for several jobs, and 150 DPI always looks great. I agree that anything more is overkill and more importantly, not perceivable.

I agree. I've used 150 or 200 dpi for my oversize prints. I'm pretty satisified with how they turn out.

Thanks guys appreciate the info!

I agree 110% with Chris.

this question get's posted way too often. it is first and foremost dictated by your plotter. are you printing it on your own or are you having a shop print it for you? if they are, ask them what resolution it needs to be for best results. when i print things on my photo inkjet, i render at 200+, but i don't use that for our 24x36 presentation boards, i use our hp designjet 4000 color large format plotter. it prints things a bit grainy no matter what the rez. i get the same results on down to around 150dpi. either ask the printing people, or experiment to see how low rez you can get away with
