dpi problem

I recently created a A7(74mmx105mm) flyer using gimp and sent the image to a print company who replied with:

The artwork you have sent is only 72dpi. Therefore, too low resolution to print from. Ideally artwork should be 300dpi.

Here is the image: http://www.imageox.com/image/354977-GetAttachm.jpeg

What do i need to do to get the higher dpi?

Any help would be most appreciated. Thanks,
Si.

Redo the flyer at 874x1240 pixels, which makes out to 74x105mm at 300 DPI. Don't just resize the existing image, as that will either make the image blurred, or blocky when printed.

I don't really know much about gimp but just playing around with it for a few seconds, why not scale image but change the x, y resolution to 300 ppi, doesn't seem to have dpi, in the drop down menu. The size of the image doesn't need to change I think.

I was hoping beyond hope that i wouldn't have to do it again. Oh well the first time was a learning experience, I should be able to do it faster this time.

Previous answer from Jernej is correct. But when I take a look at your flyer I see, that critical point is white letters on the background. If U have possibility to remove letters (or have background image without letters) just resample (scale) image up to 300dpi, and put the text again on it. Maybe U save some work and time this way.

Will this not make the image blocky?

I don't think so. Rather blurry. But your background is not sharp, crisp and spicy. That's why I suggest to skip some work with creating background, cutting computer etc. Try and see. If it doesn't work, or U affraid of quality - redo image as Jermej says.

U can try few different interpolation method. But probabelly bicubic is the best one.

No, for upscaling Lanczos is the choice. ImageMagick provides many algorithms and I have made many tests for enlarging a picture. Peter

Thanks for all the quick replies. I'll give that imagemagick a try tonight or tomorrow.

Lanczos is possible in Gimp too :) - the third option - Sinc(Lanczos)
