Very exciting! - I look forward to seeing more as the process is certified for commercial sale. Calvin is clearly on the case with the toxicology etc. so I hope it takes the world by storm when released. Bravo!
Are we talking dry pigments mixed with the emulsion? That would be good news for me. Registration for multiple passes sounds almost impossible. Would love to see that discussed. And does anyone remember Kwik Print? I purchased a small bottle (black) back in the 1980s and made some contact prints that were very pleasing to me. I thought of it as gum prints in a bottle, but don't know what was in it. It was sold in black, magenta, cyan, and yellow, IIRC.
Polymer? Hmm. Ok. Ill check it out if and when anyone doesn anything important with it. It could end up like the VanDyke Print. A process that shows up more in photography classrooms that museum walls or photo history books.
While this is exciting to see a more nontoxic process i wish the active agent used to replace the dichromate would of been mentioned. I'm about to buy some Potassium Dichromate for rawlins oil process but can't help but feel there may indeed be something non-toxic available as a substitute.
I have no idea what is the sensitiser in this emulsion, but whatever it is it would not be suitable for oil prints. Dichromates make exceptional relief with great dynamic range.
For oil printing (but also carbon printing, collotype) you can use diazidostilbene / DAS (CAS: 2718-90-3). Unlike dichromate, DAS is non-toxic, non-carcinogenic and has no dark reaction. It's very sensitive to light so it must be handled under safelight.
As others have suggested ferric ammonium citrate or diazidostilbene can be used to replace dichromates for your purposes. I have experimented with both for collotype and think that FAC is the better choice - easier and cheaper to obtain and use, plus altering concentration does appear to affect contrast, unlike with DAS.
Well a variation on a theme, it will be interesting to see the difference - obviously a wider tonal range - from Dichromate, i quite like the poisonous stuff keeps you on point 🙂
Hey Borut, great intro to the process, I got myself a bunch of the printmakers friend as former workshop customer of Calvins, will you be doing a more in depth, step by step dive into it, specifically the photoshop / calibration part ? Would love to see that ! Thanks for this. As always, entertaining and insightful.
Amazing! May be inspiration for another project/book? Because I would like another one to complement your last book on my coffee table. :-) Question-which ink jet transparencies do you recommend for digital negatives? Is there a difference nice between commonly available products out there?
The print quality is so high thus it seems that this technique is more about the poligraphy other than art. I see very well printed posters and nothing else. Isn't it easier to print them in typography?
The emulsion recipe is not being shared but for 35 EUR you get one litre of emulsion that is enough for about 100 prints size 20x25cm. I'll be sharing and promoting the process through my UA-cam channel and workshops. I have Calvin's blessings and support, of course.
99% confident his sensitizer is diazidostilbene (DAS). I did some digging and on a forum Calvin said he negotiated with a manufacturer and bought a lifetime supply. For colloid in the emulsion, he says it's a "polymer". I think it's probably PVA(PV-OH) or PVP, maybe mixed with minor ingredients like surfactant (e.g polysorbate) etc.
so for each layer you alter the pigment slightly, recoat the paper with emulsion and pigment, re-expose (registering the negative and paper carefully) and redevelop and dry? Am I getting it?
Don't worry, soon me and other people who are used to see videos horizontal will die and the vertical will be the new panorama. Until then let us all relax and enjoy the ride.
Wow, wow, wow!! It would be wonderful to see a step-by-step process!

Thanks for sharing but there's something weird going on with the audio. Sounds very distorted and "wobbly" (I can't really describe it)

I know what I'll be learning next year! Thanks for sharing Mr. B.
Everyone needs to share this, well done Mr. G.
Stay safe.Peace

That looks cool. Would love to see these prints in person.
very cool is the audio a bit weird or is it just me
OMG !! THIS IS THE COOLEST THING !!!
Excellent , now if I can learn rest of process , and have room for equipment ! YES. Great video Peterlin
I don't understand it but it looks very cool
Exciting Stuff!

You can use ferric ammonium citrate as an alternative to dichromate. Look into the Chiba process of printing
For oil printing (but also carbon printing, collotype) you can use diazidostilbene / DAS (CAS: 2718-90-3). Unlike dichromate, DAS is non-toxic, non-carcinogenic and has no dark reaction. It's very sensitive to light so it must be handled under safelight.
Das is suitable for protein based colloids like gelatin, diazo for polysaccharides like gum arabic
As others have suggested ferric ammonium citrate or diazidostilbene can be used to replace dichromates for your purposes.
I have experimented with both for collotype and think that FAC is the better choice - easier and cheaper to obtain and use, plus altering concentration does appear to affect contrast, unlike with DAS.
Very excited about this.

No, it has narrower tonal range but with different layers you can get whatever tonality range you need.
Can you use the print makers friend to make a paper negative

This is TOP-SHIT!!! Thank you, Borut
i would have joined if i lived nearby!
Any updates on this?

Mad scientist. Very cool.

Awesome work, hope to see a recipe/process for this

Dos grandes juntos!!! Eso sí es retroalimentación!
I did this when I was in Uni :)
didn't think to do it with colour though very interesting
I love it
Wow!
🎉
More than a bit garbled and difficult to follow. Pity . The ‘instructors’ are undoubtedly able but it could be so much more helpful to newcomers .
Interesting but the French guy talks too much.
When are people going to learn to STOP making videos in vertical format? It's sooo annoying!
Don't worry, soon me and other people who are used to see videos horizontal will die and the vertical will be the new panorama. Until then let us all relax and enjoy the ride.
Funny enough, it's not vertical, it's square.
Too funny! Vertical is still the format of choice for many - including filmmakers.
