Professional Graphic Design Help.

So I have this image that I'm thinking of having professionally printed. It's 24x36 inches. I drew it along time ago on the computer just for computer use but now I'm gonna redraw it for printing purposes.

My question is and for the moment lets ignore weather it would be feasible or manageable if I did it at 1200 DPI or even 2400 DPI would that be overkill for a 24x36 image to achieve a very high quality printed image? Also what file format would be best? Tiff, Png, Bmp?

I concider my self an intermediate Gimp and Photoshop user but I'm not that knowledgeable when it comes to designing things to actually be printed.

Any help with this would be great.


Also should I be using a vector program like Inkscape or a program like Gimp or Photoshop?

If this is an illustration, .tiff, if it's an image, .png.
Most images that large are typically inkjet printed and usually are designed in cymk

As far as programs, I am not too sure. I worked at kinkos during college so some aspects of printing may have changed since 2007.

I'm still with my morning coffee so an error in thinking is possible

The size in inches/cm has nothing to do with the dpi and the monitor is playing tricks on you.

The normal print quality is 300 dpi and it doesn't really make sense to create a 24x36 inches picture with 2400 dpi. A normal printer that only can print 300 dots per inch, won't to be able to put 2100 additional dots to that particular inch. It'll enlarge the picture instead. Do you want to print a housewall with it?

Let's take a pic of 60 cm (which is almost 24 inches).
With the web resolution of 72 dpi it'll come out at 14,4 cm. it'll be smaller.
A resolution of 2400 dpi will turn out as 480 cm.

That's at least how I have understood it.

But if you want to have it printed professionally and go to some professional printing-shop, why don't you call them. They should know their business and tell you how they want your picture.

Yeah no I'm gonna take it to a print shop not print it at home.

Then ask them what resolution and file-format they'd prefer.
