This is an image of skid-proof rug pad. You can learn more about preparing these images for thermofax screens in the tutorial "All about Thermofax Screens". You can also learn how to "frame" new screens with water-proof tape in the same tutorial.
Thermofax screens can be used with thickened dyes, acrylic paint or fabric paint.
The paint or dye can be squeegeed across the screen with plastic tools that won't cut or damage the screen.
The most important criteria for choosing a tool is matching the width of the tool to the width of the screen. Above are 3 sizes of Bondo scrapers from an auto supply store (fabulous), stiff squeegees with thin plastic edges, a plastic putty knife and old credit cards (stiff plastic).
I like pulling images on a slightly padded surface like a layer of felt. I cover that with a piece of cloth to protect the felt from any paint that might bleed through.
I lay a piece of cloth down to receive the image. I place a bead of paint at the top of the screen.
Then holding the tape at the top of the screen to stabilize it, I pull the squeegee across the screen at a 45 degrees angle.
The angle is imperative. It is better to be closer to 90 degrees than 10. If the squeegee is too flat, the paint with spread under the screen and the image will look thick and blurry. You want a sharp image. Also print the image with ONE pull. Subsequent pulls will also make the image look thick and blurry. The best way to learn this is by practice.
As soon as you are finished using a screen with fabric paint or acrylic paint, put it in a plastic basin with water in it.

The only things that will hurt your screens are melting, cutting or letting paint dry in the void of the image. The paints or dye need to be able to permeate the image. If you are using thickened dye, this does not apply because thickened dyes will wash off the screens even if dried.
After the image in paint has dried, you can heat set the paint by covering it with parchment paper and ironing on the cotton setting. If you are using dyes, batch as you would any other dyeing project, do not iron.
Why use a thermofax screen and not a stencil or stamp. The main reason for using a thermofax screen is that you can produce fine lines that are not possible with a stencil or stamp. See the veining in the maple seeds below. That is the beauty of a thermofax screen.
great post!!
ReplyDeleteThanks so much... I do use Thermofax screens, but not often. Your tutorial is clear and concise and will be great for a visit from my students at the College here in Kingston, ON. One of our students has a small Thermofax business, so this might help the students "see" what Peta Bailey can do for them.

Well hey....it's 2020 and I am just seeing your wonderful site now, as I hunker into the Covid19 isolation world. Really great way to explain Thermofax, and I can't wait to keep reading your stellar fiber information! Thank you so very much! Chris Burton
