A Slick Way to Transfer Printed Designs onto Curved Surfaces Here’s a process suitable for bisque-fired pots that yields graphic imagery! Shawna Pincus

Surface design techniques are endless but often favor application on flat planes. Since many ceramic surfaces are not flat, potters have come up with clever ways to transfer screen-printed designs to their work. 

Today's post is another example of this ingenuity. In this excerpt from the Ceramics Monthly archive, Shawna Pincus explains how she uses a tool used in printmaking to transfer screen-printed imagery to her pots. - Jennifer Poellot Harnetty, editor

Preparing to Print

Gelli printing plates are readily available at local craft stores, or online. They come in a variety of sizes, so find the size that works best for you and your work. I tend to use smaller 4-inch circles to print on small items, 5-inch squares for singular or vignetted images, and an 8×10-inch rectangle for larger, continuous designs. Creating a screen with artwork is its own process. There are many screen-printing kits you can buy through a variety of online and physical stores (see the Resources list at the end of this article). Screens are pretty simple to expose, easy to store, and fairly inexpensive. 

Since traditional printmaking ink won’t stand up to the kiln’s temperatures, a ceramic pigment must be used. Commercial underglazes come in a variety of colors and work well with the screens. Underglazes will need to be thickened before using them with this process. This can be achieved by simply leaving the jar lid open for a few days, and stirring occasionally, until a sour cream–like consistency is reached. I find that different brands of underglaze, and even different colors within the same brand, need to be slightly different consistencies in order to print properly, so some experimentation is needed. 

Method

To give a little extra cushion before printing, place the Gelli printing plate onto a sheet of thin craft foam. Lay a screen face up on the printing plate, keeping in mind that your image will be transferred in reverse (make sure to consider this when designing your image, especially if you are incorporating text). Apply a small amount of thickened underglaze to a squeegee or flat rubber rib (1), then, holding the screen with one hand, drag the squeegee across the screen at a 45° angle, making sure to evenly distribute the underglaze over your image (2). Lift the squeegee and drag it across the image again, angling the squeegee up a bit more to collect the excess underglaze. You may need to repeat these steps to completely cover the image with an even layer of underglaze. 

Lift the screen from the Gelli printing plate (3). Working quickly so the underglaze doesn’t dry out, gently roll your pottery over the image on the printing plate (4). The dry ceramic surface will absorb the underglaze, immediately transferring the print from the printing plate to your clay. To print on a flat surface or interior, pick the printing plate up and gently press it onto the surface of your piece. Once you have completed a print, clean up the Gelli printing plate with a damp sponge, dry it off, and repeat the process. The screen can also be cleaned with a damp sponge; however, there is no need to clean it between prints unless the underglaze starts to dry and clog the screen.
