Can i turn a 72dpi into a 300dpi ?

[viccar]

Sorry im not very good at images and dpi so this might be a silly question.

But i have an image at 72dpi can i change it to 300, or does it have to start off as 300.

As long as you have decent software like Photoshop and use the default settings for changing the image size (to make it easy for yourself) There are limits of course on how high you can increase the quality for printing. A desktop sized 72ppi image will give you a good print.

I've seen dodgy sellers using small 'stolen from google images' at 72 ppi to print mugs etc and I love reading customer feedback complaints about pixelated images!

I would so love to know these "settings" the most common pics are off ppls phones which are 72dpi what are the top tips to improving these? Although using coreldraw I've been doing ok without having to change too much but as I'm getting more orders I would like to improve the end result if anyone wants to share what they do free hug involved.....

Goonergary I have photoshop elements 7 could you please explain how to use these settings.

You might like to try 'Free Photo Converter' and 'Jpeg Resampler' and 'Vector Magic' all free to download. Although when I started into print about 3 yrs ago I asked the same thing on another forum populated by some 'big hitters' in the industry. I was getting images of 100kb from people wanting 2 mtr banners from it and was pulling my hair out trying to resample the images.

This was the 'definitive' answer: 'You have to realise you can't polish a turd'............their words not mine.....LOL

There is only so much interpolation that a programme can do which in itself limits just what you can do to make the image printable.

I was wondering if i could polish the turd :biggrin:

I do explain when people send me low res images that they wont be as good as a high image res, and havnt received any complaints yet, only doing smaller items, mugs, mousemats, coasters ect.
Just would like to improve them if i can.

Try the programmes I recommended viccar...they resample and then you can size them accordingly with the new higher resolution.

I would have been more helpful in my earlier post, but I was heading out the door and only had the laptop switched on.
I use the full version of Photoshop, but I've googled the info.

Image> Image Size, change resolution to 300ppi or 240 ppi for desktop printers. Change the width and height to suit your mug template.

the DPI figure can be totally misleading.
you could have a 1dpi image that is sized at 10,000 inches x 10,000 inches, or a 600dpi image that is sized at 1/4inch square......
look at the total number of pixels, and divide it by the size you want it to be to 'calculate' the dip you will be using the image at.
Most mugs images are about 3inches high.
300dpi is professional resolution
200 is very very nearly as good.
150dpi and the image can start to look a little soft
125 dpi - slightly more so
100dpi and the image will definitely not be pin sharp. very small text will start to look ropey but photos generally still look good
72dpi (screen resolution on older monitors) - photos soft but still recognisable, accepted by most people. text can begin to look ropey, especially small point size. curves can begin to get steppy.
50dpi, more so
25dpi more and more so, - faces just recognisable, some clients still happy, but professionally, very poor
10dpi, - try screwing up your eyes and guessing.....
