The Yudu images photosensitive screens, unlike the gocco thermal imaging process. Yudu is more like traditional screen printing, super-simplified.

For instance, you don't need to mess with liquid chemical emulsion - the Yudu uses a sheet of emulsion that is ready to apply to the screen "silk". This is done with water and a squeegee.

After applying the emulsion, the screen must be thoroughly dry before you expose it. The bottom part of the Yudu has two dryer slots with a fan, and the screen frame is slid in, to dry under gentle heat for about a half hour.

The artwork must be printed or drawn onto transparent (or at least very translucent)paper, and must be completely opaque so that the exposure light cannot penetrate those areas.

The image and the emulsion are sandwiched on top of the machine and the lid closed firmly, then exposed at the push of a button for a self-timed eight minutes.

After this, the screen is rinsed under cold water, which washes away any areas of the screen that were blocked from exposure ...and the screen goes back in the drier slot to cure for another 20 minutes.

Finally, the fun part! Lift the top lid, slide your paper or fabric onto the print bed, close the lid, pop the screen in place...and ink up. It's an affordable, easy and non-toxic way to create and print custom designs. Screen-printing works on fabric, paper, and ??? ...more on that as we go!

I also LOVE that the inks are waterbased and - like the Permaset Aqua inks - are non-toxic so no fears about the watershed or septic. YAY! Plus, very easy to clean up...

 No worries about only using proprietary materials, btw - Aquaset and RISO inks in jars are excellent for YUDU printing. We've also tried thickened fabric dye, Speedball blockprint inks, and Speedball screen print inks...love the color range, and the prices are a little ... kinder. 

You can DIY with alternative emulsion sheets ! Just be sure to work with some that are more light tolerant. Some are NoT, and it gets complicated working in the dark with those. 

We experimented with a red emulsion that works well, and have also applied opaque stencils instead of working with a printed transparency...you want to make sure you adhere it on the underside of your printing screen, of course, which you should be doing with the emulsion sheets anyhow.

Have fun! Let us know how it goes!
