72DPI to 300DPI

[turvas]

Hey there. Those of you who red the topic title probably know what I'm gonna talk about. Yep. Increasing the resolution of a 72dpi image to 300dpi with no quality loss. But I'm no moron. The point is: I have a photoshop file, which is made entirely of shapes, not a single raster layer. Is there a quick way to change the dpi to 300 or do I have to rebuild the whole image?

Image > Image Size...

Type new resolution into box marked Resolution:

No need to rebuild your image.

Are you changing the res for printing?

A thousand thanks. Yes, there is a chance it will go to printing. Nothing sure yet though.

The only reason I ask is because a lot of people think that dpi is important for web graphics. (It isn't - it's virtually irrelevant)

[turvas]

Yeh, I know that it doesn't matter in web graphics. Thanks.

It doesn't matter for printing. They just think it does

How nice of You to spam, but it does matter.

The advice about is correct, but you should remember that when you upsample an image in Photoshop you will introduce Interpolation.

In some cases you can avoid this by only changing the resolution with "locking the pixels" which basically means taking a 72 ppi file at 28 x 30 and changing it to 300 ppi at 5 x 7. Only the image dimensions change size, but you leave all you pixels intact.

So if you can do this with your current file and the small size still works for your needs, that will be helpful.

Yes, I already figured that out after a few fast test prints. Still, thanks for the advice.

Is there any success software or tutorial for this method?

Use vector format and shapes, that is the key to high quality.
