We want very high resolution images for printed versions in JPEG. And
resolution so becomes an important concen for us. When u poof it to 800 dpi
directly from 72 dpi your are not adding any information. You can always get
the resolution down when you have a high resolution image and get the
desired effect. Do u know of some method to take high resolution outputs?
will appreciate it .
Regards
Ashley.
