My preservation mounting preferences have taken this turn:

Sink mount = used most often
Cons. Corner mounts with CC tape reinforcements to the corner mounts only = 2nd place
Hinge mounts = 3rd place (rarely done; used for float mounts mostly)

My reason is because I try very hard to use noninvasive procedures. I truly believe that anything 'wet' - no matter what pH - could create adverse effects.

SINK MOUNTS take SO much longer, thus I don't enjoy them, but feel like it is best. I used to mount the rag pieces with GOLD ATG tape, but have changed to white glue. And for thin 'art paper' I use 2-ply rag. I suppose the top mat should be adhered with white glue also.....????????

QUESTION to all of my "guru's":
Given your experience, is there a reason why sink mounting should NOT be used?

Thank you!
 
Sherry- Sink mounting is great for items that have some thickness (about that of 4-ply board or more), but personally I wouldn't trust 2-ply to provide enough of a "ledge" to hold a work on regular paper. Eventually it may slip past the bottom sink edge due to expansion and contraction. I like the idea of edge supports as opposed to hinges whenever possible, but I don't like to depend on the corners alone to hold the paper-borne art, because the paper can deform due to its weight being held by the bottom corner mounts alone. I would recommend supplementing those with a strip of folded Melinex along a decent amount of the bottom edge, held in place by 3M 889 tape. These are easy and quick to make, and are a very productive use for odd leftover pieces of Melinex too.

P.S. If you or an employee have some "down time" you can engage in the hobby of mass-producing edge-mount strips and foamcore spacer strips for filling the channels of metal frames in lieu of those nasty clips. It's handy to have a bunch of strips ready to go when you need them.
 
The other reason hinges are often preferred over corner mounts or sink (I wouldn't sink mount unless the piece had some thickness as Rick says) is gravity.

I ran some experiments with my diplomas. I mounted one of them with corner mounts and one with hinges.

You can see the wave effect of the corner mounted one "settling." It's subtle and I suspect most of my customers wouldn't notice, but it's just not right.

Proper hinges are reversible and shouldn't be avoided for most things. IMHO.

That's why I like to use the Melinex strip support along the lower edge when using corner mounts. The cost and time factor are negligible.

Avoiding 'sinkage' from corner mounts

WHEN I use corner mounts, I do the corners first and then I cut corner mounts in half, and trim the sides about 1/32" (that way there is no indentations on the sides). Then I cut across the back portion so that it is lateral to the top, but extends about about 1/4" from the top flap. Are you with me??

Depending on the size of the piece, I do at least two for the top and bottom and one for each side (16x20). I do more as indicated. I place one on the middle of each side and two at equal distances on the top and bottom....more on the bottom depending on the art. Then I run a piece of CC tape from the middle of the top flap to about 1/4" below the corner mount, making certain NO TAPE IS NEAR THE ART. The placement of CC tape on each mounting piece is security! On each corner there are two pieces of tape, crossing over each other at the corner.

What might the drawbacks to that procedure be?????

I just think this is much faster than trimming to size, folding in half, cutting openings, etc., etc. to make a 'well' for the art. Perhaps if I did it often enough I would become faster.

Thank you for your input! I understand your comments about thin 'paper' in a sink mount.

See you at WCAF???
 
Sink mats done in daisy with scrap ACFC then trim out after is about as fast as it can get.

You find "anything 'wet' - no matter what pH - could create adverse effects".

and yet you have "have changed to white glue."...... ouch? :eek:
 
Sherry- I'm not sure I picture exactly what you are describing as to the trimming of the extra corner mounts. It sounds like a lot of work. Also, what is CC tape?
:kaffeetrinker_2: Rick
 
ConClear of coarse... unless its that "upscale" tape with the "Closed Corners"....

or maybe it's just Clear Cellophane tape. . . . which would not be the same at the athletic tape we found in a jersey frame job about a year ago..........
 
Clarification

Where is Dr. House's "white board" when I need it??? ;)

"CC Tape" = Scotch (3M) 888 Conservation & Preservation Tape........discontinued but I have a bit left. I think Jim Miller said it is now 889?????????

Baer: I'm glad you raised the "wet" issue. I don't like to do hinge mounts because the paste (etc.) is wet and being applied TO the art. Of course, when float mounting, one has no alternative - at least that I know of!

The WHITE GLUE is, of course, NEVER applied to the art! I would use that to attach the "daisy ACFC or mat board" for a sink mat OR to attach the top mat (window mat) so the opening doesn't slip off the art work itself. I USED to use Gold ATG tape but someone told me that was not a good idea - SHOULD the art work fall down behind mats....the dried glue would do no harm, but the ATG could really foul things up! TRUE?????????

Baer: This particular art is on "manilla paper" - it is thin. Thus a "daisy" of ACFC would be too thick for a sink mount. BUT, you raise yet another good question......is ACFC 'safe enough' to butt up against a $1500 piece of art? I've always thought rag mat was the 'treatment of choice'. I'm asking because ACFC great to use!

Thanks to all for staying with me on this!! :)
 
Hinge-free support is always a good idea, if it can be safely done. It requires covering the edges of the work, whether it employs edge strips, edge wrappers, in combination with sinks, or used alone. Hinges require the use of adhesive (starch paste) which is benign as possible, but it does represent adding something to the work, being framed. There are many techniques that can be used to support works on paper: hinges + crosspieces, pass through hinges, reinforced hinges, perimeter hinges, edge strips, edge wrappers, padded spacers, taught paper covered spacers, and each has a role to play depending on the requirements of the work to be framed.

Some days you just have to beat the man from Washington.......

Hugh, you forgot the "Tag Line"... "And most of this I will be covering in my classes in Vegas; as well as micro and macro dots." :D

just helping sir.... see you in a few weeks.

Sherry, AFFC on $1,500 art on Manilla paper.... no.... but "Z-fold" edge clips out of 1-ply rag downed with 889 and dots of PVA? Sure.

Where AFFC excels on a Daisy is when your slapping 150 Sports Illustrated mags into Poly-styrene glazed, double mat and back, pressed in a back loader.. due on Saturday....... at 5 minutes per . . . :D
don't ask.. I'm trying to forget.
 
Art work is to the edge of the paper

Thank you so much Hugh and Baer! Your dialogue was very helpful.

My first goal with this project is, of course, preservation. My second goal is trying not to cover art which is drawn right to the edge of the paper. WHY DO ARTISTS & PHOTOGRAPHERS INSIST ON DOING THAT??????? The paper is too fragile (has been mounted on regular foamboard then shrinkwrapped for years) for a float mount.

Baer - you are SO funny! I can just see you slapping those magazines together in a PERFECT "Baer Production Line"! :)

Sherry, the artists do that because they want it framed without a frame, or with an invisible frame if a frame is absolutely necessary. After all, you don't want the frame to overwhelm the artwork.

Of course, that begs the question of why they aren't creating better art in the first place.
 
WCAF/PPFA classes

Good one Paul!!

I would LOVE to take Hugh's class (yours too Baer) but I don't see either listed at WCAF! And as much as I'd LIKE to, I can't stay on for PPFA.....something to do with W-O-R-K. :)

Wish I could!!
 
If you don't stay, we can't help you. But admitting you have a problem is the first step....

Now just go to work on your chapter about getting us down there.... the wife wants to get back to the Inn at Camelback Mountain.. and the spa... :D
 
I'd love to meet the Mrs. SO COME ON DOWN! We just might have to splurge and have din-din at......oh, say maybe........Ruth Chris's???? :)
