I would like to have a clear idea of how I can send images to the print office. I sent them as 72 dpi and they asked me
to increase it to a better dpi quality. I want to print some brochures so the images should appear crystal clear.
The size of the my prochures is 800x600 pixels. I would like to keep this size but increase the dpi.
Could anyone explain me the concept behind this and how I can increase the quality?
