Rico´s New Achievement!! Chocolate Silkscreen Printing


Retaking a thread since 2008 on silk screen printing with cocoa butter, started by @ christina-durta. 10 years later I achieved an advance on the subject.

After having some years in pastry. and then in textile screen printing I was able to get the experience to produce apparently safe edible silkscreen.

If someone is interested in retaking the thread, I can tell you specifically what information I obtained since then. Surely someone can help to understand global regulations for this issue.

Soon more photos and videos!

great @DiscoverChoc!

Translated with google. sorry for the mistakes.!

Do you know the problem of the emulsion of making the stencil that allows you to stamp with chocolate?

All this time we were looking for the "holy grail" of safe photosensitive emulsions for chocolate. The comercial food grade emulsion , dont exsist.

The issue is that in the legislation we will not find the word emulsion photosensitive. But if we know the ingredients of the emulsion we can trace them on the positive list of approved resins to get in contact with fatty foods.

Basically Polyvinyl Acetate + Sensitiver + Color + Water.

Polyvinine acetate is the basic ingredient of white glue and chewing gum.

I would feel safer using the latest generation of photosensitive emulsions. Called. Emulsions of pure photopolymer. They have less odor, no toxicity, low exposure time, long run time.

These emulsions do not have DIAZO, which has an intense yellow color that can stain the screens.   After the development of the screens, you should proceed to a post exposition to the sunlight and then it must be carefully degreased and washed with cold water!

Finally, in the legal question, it will depend on each country. If you want to sell chocolate-made tranfers you will have to make approvals that will include proof of transfer of ingredients from the chocolate emulsion. And if there is migration this should not exceed certain limits (12mg x kg)

Tomorrow I will prepare some screens, I can document with photos !!

I am interested in reopening this thread here and would love to see photos and videos. of what you've learned.
