High resolution gifs…

Simple question here (I would think)…

Whenever I have a high resolution which I try to save as a gif file, it is automatically converted to 72ppi at a larger print size. I know this technically maintains the correct number of pixels, but I want it to stay at the original print size and resolution.

How do I do this?

Thanks!

are you using save for web? try using just File> Save As.

if that doesn’t work, i’m not positive gif actually supports resolutions, i’m sure someone more knowlegable will chime in.

Janet,

The .GIF format has no way of storing physical dimensions/ppi information. It is up to the receiving application to decide at what resolution to display a gif and every one that I am familiar with will assume 72 ppi.

Also, keep in mind that it is a format that is optimized for screen view only (hence the 72ppi limit) and was never intended to be used as a print format.

What are you trying to do? There may be a better format we could suggest. Are you just trying to get transparency with it?

GIF is limited to 256 colours, so it is seldom used high resolution for print. PNG has fewer limitations (as a web alternative), but tiff or psd with or without transparency are what most people use for print. If it is truly <256 colours, it probably should be a vector image if you need high quality print.

Well, recently I was reworking a logo for a client, and I had a scatter sheet for him to print out so he could see the samples "in action". Saving a full sheet as a tif was a little large for emailing and it was something that looked fine with 256 colors so I thought it was worth a shot. But I wanted it to have the proper print dimension. Anyway, now I know gif isn’t an option for hi-res. (thanks for the info) I ended up using jpeg for this one, which worked out okay. I should have tried eps… didn’t think of it- next time I’ll check that out. And there is always PDF for some instances…

Thanks!

If file size is an issue and you think JPEG worked ok, don’t even bother with a Photoshop EPS. You’ll either save it without any compression or end up applying JPEG compression to it.

A real logo would be better built in a program like Illustrator though. Saving it as a vector EPS through Illustrator would result in a super small, super high quality file that is scalable to pretty much any size.

…. but if you don’t understand anything I just said in that last paragraph, you’re probably better off sticking with your JPEG.
