Just saying, you can call it the way you want!

    Yes the Clear Casting Epoxy is what I am thinking of. The same stuff they have on that site link you supplied. That link is a good source for the color pigments. I will ad that to my favorites for future refernce. Thanks!

    I didn't know that signs are refered to as horizontal length and Verticle width but now I do. Thanks! I can use that information now that I am almost a sign maker.

    I know this thread is several months old. But I was searching for a way to do color lithopanes. Painting is too much work...I guess I am lazy... I did find another solution for smaller corian projects.

    Reference: http://www.vectric.com/forum/viewtopic.php?p=18356

    1. converted the color image into a CMYK image then deleted the "K" channel which is the black or shades of gray that the lithophane already represents.
    Then glue the transparency to the back of the lithophane being sure to line it up just right.

    NOTE: They look the same as a regular Lithophane from the front without back lighting (and if you give them a light spray of mat-white lacquer you can't see the transparency from the back side also).

    2. I used 3M Super77 spray adhesive, it has no affect on the ink and gives you a little bit of time to line up the print before setting up.
    This adhesive can also be used to attach a lithophane to glass...

    I think I want to try this and see how it works out

    Hi Denise

    I had done that before where you print three seperate trasparencies -Cyan Magenta Yellow and black and it works for a color overlay visual aid but it was kind of blurry. I don't know what it would be like all glued together though. For outdoor use it would probably not work but in a light box it might.

    Alan,

    It is a little fuzzy...the pictures I took was because my hands were a little shaky...but I think it turned out nice.
