Re: double sided images - Duratrans?

    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

                      I should have asked: on what size
                        and thickness are you printing?

                                Duratrans and similar is
                                  translucent and is the material to
                                  use. Despite Yoram’s comment, do not
                                  use glass. Just try putting a piece of
                                  4x8’ quarter inch thick glass up as a
                                  display. The first problem is its
                                  weight, not that it is breakable. 
                                

                                Furthermore, try to imagine what
                                  could happen if Abu Nidal decided to
                                  hijack your image. It won’t fly any
                                  better on glass than it would as a
                                  ferry. I’m sure engineers have other
                                  ideas, but a sheet of tempered glass
                                  would shatter into a million
                                  itty-bitty pieces while still on the
                                  runway. If you lab (if you have one)
                                  has no ideas, get in touch with duggal.com in
                                  NYC.

                                        I don't know if
                                          it's relevant in your case,
                                          but when an image is printed
                                          on glass it behaves
                                          differently, depending on the
                                          position of the light source.
                                           It behaves as you expect, as
                                          a positive image when using
                                          reflected light, but behaves
                                          as a negative when using
                                          transmitted light.  (FWIW, I
                                          could not believe this, in my
                                          gut, until I tried it myself.)
                                           So if you want to look at it
                                          using transmitted light, you
                                          have to print the negative on
                                          the glass.  
                                          
                                            
                                          You'll have to be pretty
                                            clever and use some
                                            sophisticated setup if you
                                            want to have the image look
                                            the same from both sides.

                                            
                                            Also,
                                              I recommend glass rather
                                              than some flexible
                                              material.
