    Printers do not print dots one on another but they print in a row.
    So you can print with RGB colors and get a full color print.

    Yes, you're right. Orange, green and violet. I'm sure it would work withe red and blue though.

    As for growing pre-coloured potatoes for their starch, This reminds me of something I read about Fender (the guitar company) injecting trees with dye while they were still growing to get some interesting wood colours.

    Just wondering out loud, here...

    If you want to shoot black and white and color images of the same subject with one single exposure, I wonder if it would be best to do it with something like the three-strip camera used in the original Technicolor process. The final print could be made by dye-transfer/imbibation.

    You could even use the same camera setup but with only two strips of film, one traditional tri-pack color and the other black and white. But, if you did use three negatives you could combine them any way you want to produce your desired effect. If you wanted to print them with the traditional CMYK matrices, no adjustments need to be made but, if you wanted black and white you simply print only the matrices that are needed to produce your desired effect.

    (Could it not be done by simply printing the blue matrix as black?)

    Steve , Ian , if you interest in aircraft building and if you need strongest fiber for lowest weight , you can search for israel , germany research , growing spider silk with first deconstructing its dna , inject to bacteria , injecting bacteria to the potato and growing spider silk on the potatos.
    You cant grow spiders a lot together because they eat each other

    Of course they do, but they can also make two passes and print a yellow over a cyan to get a green. This is why they use 6 - 8 inks including black.

    However, Autochrome and Dufay do the same, and with transmitted light can reproduce whites, but when coated on reflection support appear black and white with some color spots. Same applies to color inkjet printing if done incorrectly. This is why older color printers did so poorly and why modern ones do so well by comparison. It is also one reason why color printing is effectively so slow.

    And, if you wish to take your idea further try this. Process some E6 films with bleach bypass. then look at them. They are black even by transmitted light. And, do the same with color neg film and you will get desaturated color. You have effectively added a B&W image to a Subtractive color image. OTOH, that same B&W image in an Additive photographic system is essential to getting any image at all. And, in digital printing or standard color print systems for magazines the C/M/Y/K is essential but for another reason.

    So bw and color film emulsions can be put in to the same film by a manufacturer.

    Yeah ! Good luck on getting EK to jump on that bandwagon.

    Guys;

    A B&W emulsion and a color emulsion are essentially identical. Color is achieved by adding other ingredients, extra layers and by using a special process.
