Re: double sided images - Duratrans?

Randy is right, but the long-lasting print will be solvent as the makers developed it for exactly your use: long-term exposure to sun.

There are a zillion trans materials.  No really more then you can fothom.  Ones that you can print at home or silver halide if you wish.   Really go to a lab if you need huge or go to xpedex and tell them what you want.  They will overwhelm you with options.  
As for the neg/pos thing  it wouldn't happen with color unless you are using lcd screens.  Its a result of reflectance of substrate and angle of light striking the surface.  So if you are parallel to the trans it wont under normal circumstances ever be negative.  You can make it do it if you choose.

I'm still in my pj's here, but to make the digital negative even the stuff for making overhead transparencies will work.  For that, just run them through a copy machine.

    Hi, 

    thanks, that's really helpful actually. It's interesting about the
    positive/negative effect, I wouldn't have thought about it working
    like that, kind of just assumed you'd be able to print a positive
    image straight onto the translucent media, whichever that is. I'll
    do some tests and see. 

    By the way, I hadn't heard of palldian printing, so just googled
    it...looks really beautiful! What media do you print onto to make
    your digital negative? 

    Cheers,

    Jonathan

      Sounds good to me. You can print on the same stuff
        we use to make digital negatives when we do palladium printing.
         One side has coating to adhere the printer ink.  You would just
        mount the negative on the window; no one will be looking at it
        from outside, and it will be a positive from inside the
        greenhouse.  Sticking it on the glass will need some kind of
        tape/adhesive.

        Another method, needing extra steps, is then to transfer
          the image onto any other rigid material.  There are many
          transfer techniques; do an online video search.

          But I just had a thought.  When I described my experience
            with the negative/positive effect, it was black and white.
             So light either came in or was blocked, or in between.  But
            color? Either get some other advice or just do a test
            yourself.  I have a hunch -- but that won't do.

                  Hi, 

                  So to explain it with a little more context, the
                    idea is to display images taken in an allotment, as
                    a 'pop up' exhibition (on the allotment where the
                    pictures were made...). That means the exhibition
                    needs to be weather proof, so after having thought
                    about ways to do this (printing as vinyl banners
                    etc) I had this idea of displaying them in a
                    greenhouse. I liked the idea as it seemed
                    appropriate to the subject matter. 

                  So, I wondered if I could print the images onto
                    some kind of translucent surface which could be
                    stuck onto the windows of the greenhouse. Initially
                    I thought of just printing inkjet onto acetate, then
                    I thought about duratrans. I also wondered if it
                    would be possible to print onto some kind of clear
                    vinyl that would be self adhesive so that I could
                    easily stick them to the window panes of the
                    greenhouse. Size of the panes could range between 8
                    inches to 23 inch square, depending on the kind of
                    greenhouse.

                  I imagined the greenhouse to work as a giant
                    lightbox (at least from inside, not sure whether it
                    would work from both sides). Sounds like a slightly
                    crazy idea and not completely sure it would work,
                    but interested to know if anyone has prior
                    experience. 

                  Thanks, 
                  Jonathan
