The original logo design in Sharpie.
After converting the logo to a vector file in illustrator, it gets printed on a transparency.
Here's the transparency on the light table that burns the screens.
This is the screen with the logo image burned in.
Mixing the right kind of yellow.
First try. The ink gets applied through the screen with a squeegy. The tshirt is underneath.
Bam! The first shirt.
And a few more for good measure.
