Increasing DPI for print

I have a logo that is 72 DPI that I would like to make 300 CMYK so that I can use it for print. Is this possible in Photoshop? Thanks, Andrew

Is it possible....Yes

The problem is, you are only going to ba able to print it at about 25% of its original size... you can't give an image data... and thats what you would have to do to make it 300 dpi at the size it is now. Photoshop handles that by "interpulating" pixels.... it almost ALWAYS looks bad

The only way to get a "true" 300 dpi is:

Image>Image size

uncheck the checkbox at the bottom that says "resample image" and that will constrain the size and resolution.

type in 300 in the resolution

and the size you end up with is the maximum you'll be able to print.

That was easy. It's an egg...

Here's one for you... No cheating.. ;)

This thing all things devours:
Birds, trees, beasts, flowers;
Gnaws iron, bites steel;
Grinds hard stones to meal;
Slays king, ruins town,
And beats high mountain down.

One last thing. Blowing up a 72 dpi picture of anything to 300 dpi will always look awful. If you're forced to (as I am in MANY daily circumstances), the best thing I've seen for this is to use the Genuine Fractals Printpro plug-in for Photoshop. Its basically an extra file format plug-in that saves and loads images in a format that sharpens pictures as it expands/blows them up. The difference between using this and using standard photoshop interpolation is amazing.

The results still aren't perfect, of course, but its still a great tool.

Basically I use it when a client asks to have something printed and all they provide for source material is small or web-based images. Its also good for blowing up small clipart images.
