How do I save a jpeg with 300DPI from Illustrator?

Question

I created a file in Adobe Illustrator CS2 and the printer that my client is using requested a jpeg with at least 300DPI. How do I save a jpeg out of Illustrator and ensure that the resolution is large enough?

I tried saving an eps file and then changing it to a jpeg out of illustrator but I think that is affecting the resolution. I don't know how to view the DPI on my current file in Illustrator either!

Answer 1

On CS3 you have the option of setting the resolution and quality when you export your file to a jpg format. Go to File>Export>Jpg and you will get a box with the settings. Set the Quality to Maximum (no compression) and the Resolution to Custom and enter 300 dpi.

Hiya! I'm a bit suprised that the printer is requesting a JPG and won't take an AI or EPS file... at any rate... please note that AI doesn't work in the terms of DPI, instead it's all vector (unless you imported some pictures that are not paths and curves and lines, etc). Because of this you can create a file that is relatively small, then change it to any size you want because it's all mathmatically based color and shape calculations. So, while the easy answer is - export as a JPEG with your resolution set to 300 DPI, I thought I'd add a bit more to the Illustrator answer...

How can you scale down without losing quality? By definition, you cannot. You need to play with it, scaling down to see if the lower quality is acceptable. Do you require tiff? If not, convert to png or jpg and fiddle with that. For most purposes, a very low quality is not detectable. Major cropping and large printed formats are the obvious exceptions. GIMP, Photoshop and many other viewer/processor programs allow scaling.
