I have some rather large pdf files for print production. I have been choosing "Reduce File Size..." to make my files easier to send to the printer. Things have been fine as far as resolution, but now an image has shown up looking lo-res. Should I NOT use the Reduce File Size menu option? Does it really reduce the resolution as well as the size? Some of my jobs look great so now I am concerned. Can anyone help with this? the docs from Adobe seem vague. Thank you in advance for helping!
