Thermofax Screen Printing

11 Jun 2008

thermofax screen printing fabric

A sample of my hand-dyed and screen-printed fabrics.

What would you do if you had a month off and could do any one activity?  If I could take this kind of time, I'd scamper off to some secret destination (preferably a small creekside cottage in Sedona), and shlep plenty of Procion dyes, Jacquard and Golden paints, squeegees, rags, and my thermal imaging machine, one of my new favorite toy, for some screen printing.

An alternative to traditional silk screening, Thermofax screens can be made quite easily with images that have been copied using a copier machine. (You need the ink from a copier machine to successfully make the screen.) There are new thermal imagers on the market, or you can buy a refurbished Thermofax machine from Welsh products or go on eBay and bid against tattoo artists who use them for transferring tattoo designs. If you don't want to buy a Thermofax machine but want to have something transferred to a screen, there are also people who will provide that service for you.

Claire Fenton gave me a brief, impromptu lesson  on how to make Thermofax screens ths past January at the last QA TV taping, and I've made about 100 since. It's so simple, and I am utterly addicted.

Since I've gotten this machine, I've become more aware of patterns around me that I want to use to transfer to fabrics. For instance while sorting through my drawer of quilts in progress, I found one quilt block that I had free-motioned with an interesting pattern. I flipped the quilt block over on my copier machine so the back side of the free-motion work would copy, and here's the resulting printout:

To make the Thermofax screen from the copy, you need a carrier to securely feed the screen and the photocopy through the Thermofax machine. Put the copy on the bottom, facing up, then with the smooth side of the screen facing down on top of the copy, run them through the machine. It's the heat from the Thermofax machine that impresses the image onto the screen.

Isn't this exciting?

To find out if it worked, carefully lift one corner to see if the Thermofax machine heated the photocopy enough to make an impression on the screen. If not, run it through one more time.

Above you can see the impression on the screen as I peel it away from the copy. Now the only thing left to do is secure the screen to a frame or place duct tape all around the sides so the screen doesn't curl, and it's ready for use!

Thick fabric paints work really well for this process, and I simply slap on some fabric paint along the top edge of the screen. (To make sure I've got the right side of the screen facing up, I put an arrow on the top--another trick Claire taught me.)

Here's what the screen looks like after you pull the paint down with a squeegee:

And here's a yard of fabric created from my free-motion screen, using white fabric paint.

I used this fabric for the base to create some fabric ATCs with a musical theme for the upcoming Long Beach show:

I hope this post demsytified the thermofax screen process a bit. As you can see, I'm having a lot fun with it!

No, I'm afraid I am still totally mystified. Your fabrics are beautiful.

Wow, that fabric with the white screening is beautiful! I have a Japanese product called a Gocco that does "mini" screens that are 5x7 inches. You've inspired me to break it out and play with it again!

I sooooooooo want a thermofax machine. I wrote in my blog about suffering from thermofax envy! I've done traditional screenprinting, but this is so quick and easy--and, as you say, patterns are EVERYWHERE!

I have always wanted one of these machines but thought that they costed too much money? Now that I see the actual price, I can save up for one and be able to buy a reconditioned one some day! I love the look and now I know were and what I can do with all of my doodles and things that I have in my sketchbook!!! Thanks so much for the post!

or maybe it could be like the Etch-a-Sketch? a toy that I didn't own but always, ALWAYS, played with at my friend's house. Question -- must the photocopy ink be the powdered toner used in dedicated copiers, or would a photocopy from an inkjet or laser printer work?

Pokey- What is really cool is that you can transfer your own drawings if they are done with graphite pencils (ie an Ebony pencil). You can also do rubbings of texture and use that to create the thermofax screen. The beauty of using these directly is that they have a more drawn quality to them. And man, is it fun to make textural rubbings!!! And I love the idea of craft night with your people!

Melanie, your comment cracks me up because my free-motion design *does* look like something from an Etch-a-Sketch! About the toner: One of our copiers in our office works, the other does not. The one that works indeed uses the powdered cartridge. Anything I copy from any source (as long as it's high contrast) works. So if I took a sheet from my ink jet printer and made a copy, it would work. I used to have an ink jet printer that I could take a print-out and directly transfer to the screen through my Thermofax. I do not know what type of ink it used, but it made the impression in the screen quite successfully. I would try experimenting to see if you could make screens directly from your printer. (It can't hurt because if it doesn't take, the screen wont have an impression and can be used later.)

Looks fascinating, but what do you call the material that you use to make the screen and where can I get it? I tried searching for thermofax screen without success.

Kathy, Here's a direct link to the thermal screens at Welsh Products. http://www.welshproducts.com/process/prodlist.php?cat2ID=T2&cat1ID=T I initially purchased by the sheet but because I do so much screening now, I recently bought a roll. An idea might be to go in on a roll with friends and split it up. More cost effective in the long run!

That is such a cool piece of equipment. I'm sure I could sneak one into the house and it not get noticed for a few days... And, that resort in Sedona is fabulous...just the place to relax and create.

My daughter has a few tattoos, I asked her if she would take along an image with her next time she has a tattoo done and ask if they'll make me a screen. She said no. Then she came home from college to treat me to my own tattoo. The artist that did my ink does other art too, maybe if I get enough tattoos, she'll do a few screens for me. I should have at least asked for the screen from my own tattoo. Let that be a lesson to you. Sam and I are going to get matching tattoos, she is still turning up her nose at my suggestion about keeping the screens... Oh well. Youth. Robbi

Thanks for the link. I recently found a used machine, but have had trouble finding thermal screens for it. Does anyone know of any other place other than Welshproducts who carry them?

I recently saw thermofax screen printing supplies on a German web site another artist mentioned recently. It is www.patchworkshop.de I know a little German, enough to find a selection of the screen, but not enough to sign up for an account and make a purchase.

What is the brand that is pictured above?  It appears to be the same machine that Claire Fenton uses in her Workshop, and I have strained to read the brand name or word on it.

Great information. Thermofax screen printing is very easy way of  screen printing but also there exists silk screening which is a fast and better way of printing available at http://www.westixonline.com  . It provides high quality screen printing equipment, supplies, service and education.

I've been using Thermofax screens for a long time. Here are a few hints I've discovered for making successful prints;

1. Except for very thin fabrics, it's best to make 2 passes with the ink. The first pass is very light, just enough  to distribute ink atop the screen. On the second pass push firmly downward so the ink goes through the screen for an even print. Hold the squeegee at a 45 degree angle. The first pass can be in any direction. The second one should be pulled toward your body. Making too many passes will cause ink to leak under the edges of the design.

2. Before lifting the screen completely, check the print by lifting a corner  while holding the screen it place with your other hand. You can lay it back in place and touch up any empty spots. Also, after you've cleaned the  screen  it can be aligned over dry prints to make touch ups.

3. Always  print and clean the screen from the top ( non shiny side) to avoid  damaging the image.

4.For printing, I tape my fabric to newspaper with a few small bits of masking tape. That way I can pick up each piece to move it for drying without the fabric flapping and possibly off-printing onto itself.

5. Use only water soluble inks. Oil based inks will melt the screen. Some inks and fabric paints work better than others. White can be difficult, but when mixed with a little color to make a pastel, it works great. Check often and clean the screen if it starts to clog with ink. Always make tests of inks and print technique  on your fabric before starting an important project.

Happy printing!
