I'm a photographer who does his own (fairly well) framing. Once I place the sandwich (photo, cut mat, backing board, etc.) in the frame, bend down the points, I then take acid free white tape and place 1/2 the tape on the inside side of the frame and 1/2 on top of the backing board (covering the points).

Now my question - Is the last step (tape) a good or a bad thing? In my inexperienced mind the taping secures the sandwich in the frame and helps to keep out debris from finding its way to the photo.

Good or bad?
 
Not bad. But tape the glass down to the backing board to seal the package using 3M 850 or 3M810 tape. FrameTek has a good article about it.

I also run the tape along the back like you do if the points are raised too flush to the moulding.
 
bend down the points...............Good or bad?

The biggest problem I have with what you are doing is "bending down the points."

This makes me think you are using a frame that has flexible points already inserted and are limiting yourself to either making a package of framing contents that "works" with the point position in the frame, or are forcing the package to fit with the points, or may not have sufficient filler board and have too loose of a package.

Your best bet is to either order frames without the flexible points, or remove them completely before you fit your package and buy a good quality fitting gun and shoot in the appropriate ponts at the approtriate height and spacing. The problem with removing points and then putting in new ones is you are making swiss cheese of the rabbet. Better to have a virgin frame if possible.

As long as someone brought up my hero, Greg Fremstad, he also has a great article about having a framing package too tight.

Also, what is "acid free" tape and why do you feel compelled to use it? I would be more concerned with what kind of adhesive is on the tape and what the carrier is (durability) - it may stick now, but what about in the future? If left in a warm car? If on a wall that changes in temperature? Will the adhesive hold up against an unfinished wood frame?

Re: The tape - I HATE any package that is taped in. It is difficult to remove, will usually tear the filler board, and leave residue on the frame. Properly inserted fitting staples, points or brads will never need tape. With all due respect to my fellow framers across the pond, I also do not like pressure sensitive tape in lieu of backing paper - but water activated Kraft is OK and so much easire to work with. Greg's article is not about taping in the package, but sealing it before fitting.

Get yourself a good fitting gun!
 
Thanks

Thanks to all of you for responding.

johnny - I reviewed the Frametek article. It was right on topic.

Rob - You are correct about the flexible points already installed in the frame. You asked me about the "acid free" tape. I use white artists tape that is supposedly acid free. johnny recommended 3M 850/810. I'll look those up.

Anne - I do place a dust cover on the back. I just want to reduce the likelihood of having debris. The application of the tape only takes a minute or two.
 
Attaching a full-surface dustcover is, by far, the most popular method of closing frames in the USA, but not in some other countries. Taping serves the same purpose: To close the back of the frame and make a neatly-finished appearance.

Assuming everything under the tape or dustcover is equal, then it is a matter of choice, which may be influenced mostly by the framer's appearance preferences and costs.
