- [Instructor] Thermographic printing offers
dimension and shine.
It's the look of letterpress or engraving
but without quite so much effort.
And here's how it works.
The image area is initially printed with slow-drying inks,
and then a resin-based powder is applied to the wet ink.
A vacuum system removes any of the excess powder,
and then the ink and the powder combine
and raise when the pieces run through an oven.
And then the printed area hardens when cooled.
Here the slow-drying ink has already been laid down
and the special powder has been applied.
The excess powder has already been vacuumed off.
Now the piece enters the radiant oven
where it's exposed to temperatures
of 900 to 1,200 degrees Fahrenheit.
The powder starts melting and combining
with the ink and the result solidifies as the piece cools,
leaving a raised and shiny surface that's attractive,
great for invitations and other special pieces.
