Overprint ink on foil - is it possible

Is it possible to print on foil? Background has a solid shape that needs to be foiled with a black ink over print of the logo on top. Can this be done? Or should the foil be knocked out on the areas where the ink will be? It’s a very fine font so I am concerned that the registration will be very difficult to perfect.

it is. the best way is 2 steps. work with foil supplier and ask for “over stamp-able-over printable” foil. then, test the project.
The “Dyne” can be important here. it can be regulated by die temp. this is getting a little deep for the average stamper as you don’t want to be investing in a “dyne pen” set. if you do it a lot then it may be worth it. $$.

Thank you! Will do

Just spoke with the *Van Son* Dealers/Concessionaires, locally .

The response was basically as above, Yes foil can be printed on, BUT because it dries by oxidisation only, multiple colours (superimposed) will take a long time, and slender images will be even more tricky if not impossible.
Dealers, recommendations/specs. NOT authors.

(Author) implied that it was probably from a Reel Fed H/berg Platen or similar, so the possibility of interleaving was NOT an option.

Possibly try own Van Son, Dealers/Concessionaires, Stateside.!

Thank you will contact my local suppliers here in Cape Town, South Africa and see what they recommend.

Question- why not foil over foil in this case?
If it really is just black ink- unless you desire a transparent ink effect over foil- wouldn’t it be easier and more process effective to just run black foil over metallic foil?

(Mind you, I am no expert, I am actually asking because this subject has come up, and I desire the information as much as the OP- but I have heard of both hard and easy release foils, and heard of similar situations in screenprinting as well, wherein a screen printer applied foil base of one type, and heat pressed foil onto the substrate- then applied foil base to other areas, added foil. So on, so forth. I am curious how this applies to die-stamping, even though it would be more technical?)

Print on foil? It was one of the first projects I had after hiring into my current position this year.
We added a suitable drier to the ink. As mentioned it needs to oxidize completely; there will be no absorption. The ink took days to fully cure. I was able to handle the project carefully after a couple of days to emboss it after the ink.
We did Foil, ink (halftone pattern to simulate the depth of), emboss.

Van Sons Inks had a line of inks called Hard-Tru that were oxidation type drying inks. Must clean up immediatly after use. Still need to be handled very carefully after printing and takes several days to dry.

as far as foiling over a “panel” or large area foil, you’d better do your homework there. IE: extensive testing under running conditions.Many of those foils have a different release layer that fine type just won’t stick to, dependably at least. it can be done. it is done. just test, test, test.

ericm- thanks, I am curious about it more than have intentions; So, the release layer sometimes inhibits further adhesion of subsequent foil layers? I have wondered about that but have no way to do my ‘homework’ :-)

Have you done this before?

yes.
