Screen Printing Process
Here's a basic overview to help you understand the craft and skill required in the creation of screen prints.
Screen printing is way to reproduce art onto paper using a screen stretched with a mesh where a stencil is exposed. A squeegee is used to push the ink through the stencil, one color at a time.
But a lot of steps are required before the ink hits the screen. For the Home.HOPE! prints, all art was was converted to 4 process inks that allows me to get all the colors in the rainbow.
Speedball kits and workbooks are a great place to start if you're looking to try it out at home! Visit their website.
CMYK = cyan, magenta, yellow, and black where inks are translucent and form new colors. If you find an old ad or comic book and look really close you can see the dots in the printing. It's similar, just dots are a lot bigger in screen printing.
File Prep: (boring technical stuff)
Convert art to CMYK, split channels, convert to halftone, add registration marks, and print each layer to a transparent film
Screen Prep & Printing:
1 coat screens with light sensitive emulsion where it needs to dry in the dark
2 while screens is drying, this is a good time to mix your inks - FYI, I only use Speedball inks
3 once emulsion is dry, screens are exposed to light
4 after exposure, screens are sprayed with water where unexposed emulsion is removed
5 after screens dry check for any pinholes and fill
6 place registration shims & register screen to art
7 print 1st color, one sheet at a time making sure you carefully align sheet
8 after printing, reclaim screen to be reused for next color
Repeat all steps for each color.
Once prints are dry, trim to final size and sign & edition!
It is a lot of work, but reckon it makes them much more special than any digital point from a computer. Yup!
