Today’s excitement was to learn how to screen print a photo onto glass. Below are two images drawn by Edward Wolfe that I chose to use. Our tutor resized our emailed photos and printed onto transparent plastic sheets ready for our class today.
First we prepared our canvas with photo emulsion. This was applied in a thin layer by pulling the photo emulsion upward using a trough to evenly spread the emulsion over the screen. This is then immediately placed on a dark shelf (with no light) to dry. This will absorb the image once exposed to light.
Once dry, we readied the light box by warming up the bright light and positioning our sheets of images. Quickly we transferred the now dry screen and placed this over the images, covering quickly with blackout material. Finally we put old heavy telephone directories on top to keep it in place whilst the image is exposed. 3mins and 20seconds later we switched off the light box.
The final step was to remove the screen from the light box (with fingers crossed) and to take it to the sink. As we watched the screen be showered with water, the images started to emerge. Witchcraft!
[I was doing the ‘washing’ so didn’t get any pictures of our screen at the final stages]
Different results with different colours used. Below are a selection of the glass with images from the group awaiting firing in the kiln. (You will see that I reused the red striker glass that hadn’t shown the orange powder before – let’s see how it works). (Also one of my classmates reused a powdered image with screen printed text on top.)
We’ll all have to wait until next week to see the results.
Finally, our tutor also showed us a slightly different method to utilise multiple colours via screen printing. You apply the enamel colours in splotches over the image. Then a line of the acrylic medium and pull the squeegee dragging the medium first and picking up the enamel but forcing both through the mesh. Again an interesting image created and I’m intrigued to see how that will look once fired.
