Good procedure helps a lot too. Just after cleaning your glazing lay the art package face down on the glazing. Flip it over so you can see the artwork. Slip a book under the art + glazing. Go over the whole thing with a bright flashlight held close. If you find a flub, slightly lift the glass just enough to get a sheet of clean paper underneath to push out the flub, or use your cotton-covered fingers to attack larger flubs, or lift the glass a little more than blast away with the air. Whenever you raise the glazing be careful not to drag its edge over the print or matte! Then lower the frame over the artwork.
PS if you are using acrylic glazing wipe in down & then polish on both sides with Novus #1, will completely kill the static charges on the acrylic for some time to come.
PS I have found the perfect solution to almost all framing woes which is to simply say NO to the traditional glass sarcophagus treatment. Mounted, coated canvas in a frame with no matte or glazing, it was a Eureka moment for me. Sells like hotcakes.
