Need some help. I found some great Alex Ross artwork that I'd like to convert into a marquee. Any ideas on what would be the easiest way to convert the top blue section of this artwork into a marquee for my cab (Captain Americade)?? I don't want to just stretch it to fit and print it, losing all the resolution. All ideas are appreciated!

Find the original source, scan it.
You can't upres an image without losing resolution. There are a few tricks to 'fake it' but you can't do what you are asking. From a technical standpoint it is not possible... you can't make something with nothing. If you have 72 dots per inch, and you scale up 200%, youre dots per inch will then be 36. That's the way it works.
If you do a search, I've detailed several times on this board how best to 'fake' the dpi when you upres something.

So, can I print out this .jpg in it's original size and scan that? Once it's scanned, how do I get it to be 27.5 x 7 without it looking like a bunch of los res squares? I was thinking about buying this poster and going down in size from the poster. The poster is about 24 x 36 with the blue section that I'd need being about 24 x 12. Who knows, maybe I should just go with something else...

No. Original Source... You have to go to wherever that JPG came from... a magazine, a book, a comic, an art print, and scan that. A book or a print might have enough DPI for you to get what you really want, the other two... maybe, it just depends.
You mention that there's a poster. That's really what you should go after. Scan that, and it would make a much better source than a low-res JPG.

Why can't he print that at its current resolution and then scan it at a really high resolution if he wants to blow it up? The stock pictutre looks clear enough at the current resolution.
Lets say he wanted it 3 times bigger. If he scanned it at 900 dots per inch and blew it up 3 times bigger wouldn't it still be at 300 dots per inch?

If you print a picture at 72 DPI, and then scan it at 900 DPI, it still EFFECTIVELY has a resolution of 72 DPI. See DOTS per inch... If you print out 72 DOTS per inch, and then scan those dots in, you create a really detailed scan of a bunch of dots packed in, 72 to the inch. If you want to do that, you just skip the printing & scanning, and just upres it in Photoshop. It doesn't help you either way, you don't increase resolution. Newspapers are about 35-65 dpi. If you scanned in a pic in a newspaper at 300 dpi, it would still look like a pic from a newspaper.
Another bad thing, you might create is a moir

Why don't you just use the poster for the marquee? It's 24" wide? That should be about right. Then all you'll be paying for is the side art.

Yeh, the width is good, but the length isn't. The section I want to use is probably 10-12" long and I need a marquee that is 24" x 7". I'd have to cut off alot of the art and I'm not sure I want to do that. We'll see when I get the poster.

You don't need to print it and scan it to do that. Just upres it in an application

OH, and you wouldn't get a bigger picture at the same (effective) resolution. You would get a bigger picture at a lower resolution. When you upres 72 dpi (or print and scan) to 3 times it's size, you would get a resolution of approximately 24 DPI.
