Adventures in Screen Printing

I have had screen printing in my bag of tricks for quite some time. It is the best way to get consistent and clear prints. Until recently, I have used the traditional framed screen which is durable and accurate. and bulky. Durability is important, but my style changes and I rarely use a screen for more than a couple projects. Of course, they can be cleaned off and reused. The "photo-emulsion" method produces the finest lines and greatest detail; but it is a pain for us home enthusiasts. It requires more tools than I have around the house! Enter a new product: the EZ Screenprint frameless screen. It uses the sun to develop, and I have access to abundant sunshine. It takes only a minute in the sun, some soaking in warm water, and curing time (again in the sun) to make a screen that can be used for many repeats. It is delicate and I find that paint will dry rapidly in the screen in our near zero humidity, so care must be exercised.

I decided to make a screen for our business, so we could advertise while we ride! At first I designed a screen which would tile together. The results were okay, but not great. I had little success in lining up my registration marks, so my tiles didn't match up like they should. I cut the fabric into smaller pieces and made a puzzle ball out of it. (See "Balls!" in this blog) My next attempt did not involve matching edges. I created a 6 x 6 inch square in photoshop featuring our logo, some gears and cogs, and petroglyphs.

Tiled Screen (See how the edges wrap-around?)

Non-tiled Screen (Nothing to line up!)



The square is printed out in black on to an acetate transparency. This is layered with the screen material and then taken outside into the sun.


The transparency and original print out

The layers: glass,transparency,screen, mat. All clipped together!

 After a 15 minute soak the print emerges!.

The cured screen. Note the color change and where the clips were!

I had ice-dyed nylon from previous dye sessions, (See "The Learning Curve" in this blog), and I selected a yellow green to print on. It takes very few tools to print. A squeegee, paint, painter's tape, paper towels for clean up, a tray with water, and the fabric.

The tools assembled.

I knew from my first experiments with these screens that metallic ink clogs them quickly; one strike and they must be cleaned; so I selected an indigo paint to go with my yellow green background. As you see in the photo, I marked out lines (6 x 6) on the screen. I also marked this grid on my fabric with washable chalk. Printing works best with a little padding under it. I like the height of my ironing board and it is padded nicely. I put on my cover for crafting (i.e. I don't care if something gets on it!) and began.

I found that I needed to soak and clean the screen after three strikes. Did I mention we have no humidity?! That slows the process a bit, but it preserves the screen. Soon enough, the fabric is covered.

Finished fabric

After letting the fabric and paint cure for 48 hours, I heat set the paints with the iron to make it permanent. I then sewed it into a new tool kit, the 'velope.

Voila, a 'velope!

I have some fabric left and I plan to make a mini-backpack from it. I think it clearly depicts our loyalties!

I submitted two photos of t-shirts I screened to the EZScreenprint people for their gallery, and they were chosen for display on their website! Pretty cool! I was paid in the form of more screens for which I have lots of ideas! Here's the link to the gallery: http://ezscreenprint.com/roxyb.aspx
There are in depth tutorials on their website and all in all, it's a great way to screen print!
