Turning 72dpi into 300dpi image

Quick question I am having to convert my logo from 72dpi into 300dpi for print.

I have a shape saved from the 72dpi can I simply copy and paste that shape onto the 300dpi image and then mae my light changes etc or do I have to start completely from scratch?

Thanks

Adam

you cannot just "convert" from 72dpi to 300dpi because there's information missing unless you only need a smaller version of the logo.
dpi is dots per inch, so 72dpi can't magically turn into 300dpi because the computer couldn't know what to put on the 228 remaining dots per inch - if it doesn't look too crappy when you change the resolution (generally just a resize), it might be fine, otherwise you'll have to redo the logo.

thanks for the reply, I do understand i would have to redo the logo startign from scratch but i was not sure if it would be ok to simply copy and paste a shape.

I think thats been answered now though :)

When you remake your logo-this time make it all vector. This will save you the headache next time you need to size-up.

Depends on your software. with mine I can turn a "selection" in to a path object which can be resized to infinite. Results vary and the path usually needs some adjusting but overall it saves quite a bit of time.

I have re-designed the logo in photoshop with a new canvas and set to 300dpi but the text stills looks blurred.

Any suggestions guys?

What's the canvas size? 300dpi doesn't mean anything. A 300x300 px image set at 300dpi will print out a very nice image the size of a postage stamp using defaults. That's all dpi does is set the default scale. If the image is 300 pixels wide and you set the it to 300pdi that means it's going to print 300 pixels in one inch by deafult.

If you send the same imge to the printer and specify a physical dimension such as 5 inches by 5 inches using 300dpi the image would have to be scaled up because there isn't enough pixels. This will produce a soft and blurry image.

Confused yet? :P scale your image before sending it to the printer.

Adam, while thecolaman makes a decent point for I totally agree with akmac - you should really be using a different tool for this.

If you have the time and the inclination, learn to make logo's using a vector application. It will never need scaling, will be true at any resolution and is portable and editable for all formats.

You could even use the selection to create a work path so you don't have to redraw it.

Illustrator is the best tool, a little steep to learn at first, but as soon as you have nodes and pen tool sussed you'll wonder why you ever used Photoshop for this.

thanks for the replys. I managed to sort it in then end after about 3 hours on 1 logo lol.

Limbo I think I may look into Illustrator when I do my next logo (couple of weeks)

Thanks again :)
