    Resolution/DPI help.


    Hokay well I made this picture with multiple programs and now I would like to have a 3 inch by 3 inch sticker made. Dude @ stickermule.com said that my current img was half of what it needed to be and that 300DPI was the min.
    NP, so I open it up in photoshop I go to Image/Image size and I change the resolution there to 300. The nice gent at stickmule told me that "Increasing the DPI of an image file that is under 300 DPI will not improve the quality of the artwork."
    So now im at a bit of a lost...

    Can any body out there (I mean here.) Get a higher quality of this so I can have my stickers made. It would be greatly appreciated. Thank you.

    The issue is that your image is 456px by 500px.

    First, that's not square, so it can't fit on a square sticker. Maybe the sticker guy planned to solve that by adding black bands on the sides.

    Second, 456px @ 300dpi is only 1.52 inches - that's where the sticker guy has a problem with making your sticker. He would have to roughly double the size of your image to fit it on a 3x3 sticker, which is going to introduce pixelation into the image (you can see for yourself by scaling the image by 197% and viewing at 100% zoom).

    A 3in by 3in image at 300dpi needs to be 900px by 900px.

    There is no way to programatically increase the quality of an image.
