JAC Paper

[masoth]

Like so much practical stuff I've not applied JAC paper in roughly a hundred years, and need help - there is a clever way of applying the paper to mimimize the formation of bubbles. This, I think, requires the user to cut the covering (non-sticky) paper before application.
Would any experienced member mind explaining how to go about this, please?

I suspect that you are going to use this to mount a photograph. If not, just modify the process I describe here. Being two sided "sticky" paper I apply it to the mounting board first. My step 1 is to cut it to size. I cut it to the full size of the mounting board, even if the photo is a smaller size. The oversize component is used to hold the top matt board. Having cut it to size I peel back one edge of the non stick paper about 25mm. I then line this edge up with matching edge of the mounting board. Only allow about 1mm to come in contact during this step. As you no doubt know, once in contact it is there to stay - 1mm can be pried off. Once this edge is lined up press the full 25mm down. Do this from the centre using your fingers to slide towards the edge. Now pull the nonstick paper out about 50mm. This paper will be doubled back on itself and should be easy to move. The trick is not to become too confident and cause the paper to twist and introduce a bubble. Once this step is completed the top has to be prepared. measure out the location of the print to be mounted. With a craft knife cut out the area to be removed. Make it about 1mm all round larger than the photograph except on the edge you are going to start from. Remove the non sticky paper. Now the character building part. Place 3mm wood dowling at about 100mm intervals across the exposed sticky surface. Sit the photograph to be mounted across the dowls. This will allow you to position the photograph at the starting edge and fix it in position. Now remove the first dowl and press the photograph down. Continue the process until finished. Hope this helps.

Itsa lot of fun doing it without the dowels

Thanks, two Bobs.
The way I think I remember is to lift half the 'dry' from one side, cut it narrower and replace it to the edge of the sticky - attach the exposed narrow sticky length at the centre of the picture, slowly removing the dry out to the edge and repeat the other side. You have a relatively stable item to work with. Trim to size.
I'll give your method a try first. Again, thanks.

Soth,
when I was a screen printer a few lifetimes ago, "Jac" produced a few different products and the ones we dealt with were sticky back materials for making stickers. I'm not sure what product you have or what the substrate is that your're applying it to, so the following may, or may not, be helpful.

When applying a large sticker we would use a spray bottle with a detergent and water solution in it to thoroughly wet the substrate. Peel backing paper off approxiamately half the sticker and apply it to the substrate, holding it in place with one hand as the soapy water will prevent it sticking. Then you peel off the rest of the backing. At this stage you can move the sticker around till you have it in its correct position. Spray solution on face of sticker and use a squeege to work the solution and any air bubbles from the centre out to the edges. Hey presto! sticker is stuck in correct position an without any bubbles, bumps or creases.

Mick,
I'm actually sticking photographs on both sides of a smallish piece of vaneer (one side smoothed and the other displaying it's natural grain) standing erect in other polished timber offcuts.
The JAC paper is the acid free (all is, isn't it?) double-sided sticky. Your suggestion may not be right for this use but I shall know where to find it later.

Thanks, soth

what the hell is JAC paper

[masoth]

Now, how can I be politically correct? Coloured? Nup. Ebony? Not really - aahrgggggg B***a-it.
Black1,
JAC Paper is double-sided sticky paper in sheet form. It's been available for many years and is extremely handy.

[masoth]

I got my recent lot at an art supply shop and am confident you'd get it from office suppliers too.
JAC is the brand name. Look here: http://www.jac.com.au
