Autochrome RGB Printing

[Mustafa Umut Sarac]

I had been started a thread asking that Was it possible to inkjet print with RGB inks. Result : It is possible

Than I opened a thread at APUG which listing autochrome starch dyes.
I got the list from Metropolitan Museum and they got it from L'Autochrome book in French published last year.

The dyes list are herebelow.

NOW , I am asking that , if I prepare inks with these dyes and print with inkjet printer , does it become different than autochromes ?

Of course after processing with photoshop ?

Thank you ,

Autochromes are positive images filtered through colored starch grains and viewed by transmitted light (i.e. transparencies). I don't think just printing using additive colors, even if you print on transparency material, will duplicate the look of an Autochrome. You might come closer if you simulate the colored starch grains on one piece of film and overlay this with another containing the monochrome positive.

Philip , I found your suggestion intelligently.
Printing on transparent film , bw and rgb is easy.
Than you register them together and watch the final image at wall with enlarger for office presentations.

 

[Mustafa Umut Sarac]

By the way , your ideas great Philip , may be someone makes a slide film color and bw together. This improves the image.

Hey guys,

I've proposed using slide film to photograph a television and then using that as the reseau. I've posted more extensively on APUG about it.

Turns out that it might not be possible to reach the same resolution as the original potato-starch grains in Lumiere's autochrome however.

And yes, why wouldn't printing additive colors out of an inkjet work? It will work. I believe the color saturation will be lacking however, thus my slide film approach.

I'd love to bounce ideas if anyone has some.

Thanks!
