Briefly, Strappo’s are a monotype from a dry acrylic transfer. An acrylic painting is developed and painted in reverse on a clear glass plate. When the image is fully formed and dry, to thicken the acrylic skin, successive layers of acrylic gesso are added. For the transfer process, fresh coats of acrylic gesso are applied both to the back of the glass plate and on the sheet where the image will be placed. The plate is placed on the prepared surface while the fresh gesso surfaces are still wet. Weights are placed to insure contact while the gesso layers bond. After the acrylic layers are bonded, the image and attached surface will be peeled from the glass. It is exactly the image as painted. The image, a monotype, is now transferred and the glass plate is clean. The surface of the image is smooth because it was developed on the smooth surface of the glass. A great advantage is that it does not require the use of a press.
When I want to add collage elements the layering process starts again. For the Floral pieces I create, I use acrylic paint chips from dried pigment on my palette. This is great for the leaves and blossoms of plants. They are set in place using polymer and then coated with the same medium. Wallpapers in rooms are often designed with pre-painted newspaper or magazine clippings. These collage elements are treated and adhered in the same way as the floral works, alternating layers of polymer with the pieces of ephemera.
The only other adaptation is that after all is said and done instead of adhering the glass to a surface for weights and drying, I peel the image from the glass and then apply it to a new surface. This can be paper, material and even an existing painting. And while these are still Strappo's I have begun to refer to them as Mono-Transfers.
