foil vs. varnish; gradient foil; foil on lenticular

[mamba]

1. What are the differences between foil and varnish? (look, feel, use, cost, production time ..).

2. Is it possible to have a gradient foil?

3. Do you have any experience with foil stamping on lenticular?

Thank you so much guys!

Foilstamping uses a physical sheet that's placed over the paper and a plate hot-presses a specified shape onto the paper. Varnish is essentially ink, and basically prints as such.

Foil must be stamped in a solid shape. Gradients will NOT happen.

Me, no. I'm sure someone has tried it. Don't know what the results would have been.

Thanks Virgo Nightingale.

So is it an obious visual difference when I compare 2 blue squares on white paper - one foilstamped and one with varnish?

[Virgo Nightingale]

It will depend on the foil. There are many MANY kinds. There's metallics, pearlescents, faux wood-grains, glitters, holographics... Most stampers will have a sample book that you can look through.

Thanks! Fair enough.
One more question ... when I have 1 PMS color and use it 2 times: 1. 100%, 2. 50% - does that still count as 1 PMS color? How about changing transparencies?

[mamba]

Ok, I just found the answer under the theme: Tints or percentage count as separate color?

Thanks ;)

there is a Flexo process called "cold stamping" that allows you to do foil gradients, however it can only be done at a lower LPI.
