    Hello everyone,

    i want to make big scale Cyanos. My problem is to make big Negatives. What do you recommend. Try to find a professional printing service? Has anyone tried it to make prints on transparent paper?
    I started something with an old Dia-Projector ..... it won't work ... i will need a long exposure time ....
    So, if anyone has ideas to make Cyanos with a size for maybe 1x2meters ..... let me know :-D

    Greetings from the South of Germany

    How about liquid emulsion on a transparent plastic material (like a big acetate) and project a positive slide onto it to create a negative?

    I looked into that also quite a while ago. I know they make A3 transparencies for commercial needs but I guess that's too small for you. Eventually I opted out on it because I don't have the room or equipment to handle large sheets and anything larger seems to be non-existence. But I you find something then please let us know.

    you might have to go the hybrid route, i did ..
    but i did smaller negatives en route to larger ones...
    blueprint shops may be able to help
