Gluing / Laminating

The 3M spray glue in a can is pretty handy stuff in these situations.

If the job is two sheets of common stock then work it multiple to view ,two fronts and two backs printed in one pass with a trim gutter ,then crease it throught the middle of the gutter (or perf it as i saw suggested in this case on another post)glue the blank side and fold ,this way you get all the line ups correct front to back (through the sheet).
If you can get hold of latex glue this works well as it is spirit based and tends to not curl the sheet too badly ,at least the companies i see use it have little trouble for blister work.

I’ve used 3M Super77 spray contact adhesive with good results. In my case, I printed the work first, set up front and back on the same plates with the bottoms of the art facing each other (called foot to foot) and a small gutter between the art for each side. I scored between the halves in the center of the gutter, sprayed, folded and pressed the pieces and then finally cut them to finished size. Very clean finished edges that way.

Thank you everyone for your help. I used the PH neutral glue option. I made both sheets slightly larger than the finished size lined up one edge and a bottom, and then trimmed them down. worked great!

Paul,
How thick was the stock that you mounted together?

Hi Vicky, I have been using lettra 110 backing on to various card stocks, itself back to back and book board.

It works well just VERY slow. I have been die cutting first then gluing .. I could really use a gluing machine. They are just so expensive.

I made a gluing/tipping machine out of plywood. The front component inside guides were 81/2 the length is optional. The back component is 81/2 wide to the inside at the frontal part of the back component is a trough for glue a stick of wood about 8 ” wide and 1/4” thick has 1” nails driven through the 1/4” stick. The cross stick with the nails in it is guided streight by two guide sticks about 10” long in two groves The stick with the nails in it is dipped in to the glue and moved forward and touch the top of the paper and the operation is repeated. This is typacally called a tipping machine. The glue trough can be lined with sheet metal or plastic wrap for cleaning. For small jobs it works just fine.

Hey pica12point, I’d love to see a photo of this setup if you’d be able to upload one. thanks!

The tipping machine is gone from my collection of stuff but I am thinking of making another one it is very simple.

Hey all, I want to share my experience with this very same process. I am NO expert, this was my first duplex job but I took lots of pictures and wrote a blog post explaining how I did it. I hope it helps someone, and if you have any insight on how I could do it with greater success, go right ahead.

This was the job here:

Very nice, Panthera press. That is how I do it. But have actually done it with spray adhesive. Believe me it is a huge mess.
I think what you propose in the end is almost nearly impossible. I haven’t yet devised a way to do it.
To duplex to different stocks after they’ve been printed.
The glue, depending on its tack makes this almost impossible to line up to a corner, and then glue down, in your case because it dries fast, and in the case of adhesive spray becasue it is too sticky/tacky.

Thanks Enrique. Does anyone have experience with printing on stocks that are already duplexed? It would certainly have been simpler to duplex this blue stock and then trim and print. Do you still struggle with impression showing through or does the layer of glue and double thick paper help keep it at bay?

I’ve printed stocks already duplexed. It can be done and not show through if there isn’t too MUCH pressure, and if there is no pressure to be printed on the other side, if left blank or something else.

I made another wooden gluing machine I am not sure how to send a pic through this network but if you email me I think I can do it that way Dave [email protected]

I have been gluing after printing, I put the glue on with a brush, I then place the cards long edge down back to back on a flat surface. I then pinch the two bottom corners together, then smooth out the two pieces. Its not perfect all the time but for what I am doing it is fine.

I did do it earlier this way with two over sized sheets then die cut them, that worked very well.

I was interested in the second method discussed after my post, so I tried it.

I laminated two different color stocks that had the image printed in the same place on the cards. Then I trimmed down from there. It actually works just about as well as the scoring method. The image I ended up using for this project was the real challenge, because it needed to line up to all four corners on one side and then fall exactly center on one corner on the other. I wouldn’t offer to do a double sided project where both sides need hairline lineup to the edges again, but this was an experiment offered on the cheap for a friend. Here is how it turned out:

The blog post explains my method for duplexing two different colored stocks. I think in the end, my downfall was really the trimming (even though most came out pretty good, some were slightly off on one side or the other), because I have a terrible, dull, miserable stack cutter. I had to cut them eight at a time and even when they didn’t shift the bottom cards were cut closer then the top of the stack… I think my actual blade is crooked, which considering it’s a cheap chinese knockoff wouldn’t surprise me.
