Description

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] The printing plate for monotype prints of the present invention is preferably provided as a gelatinous printing plate, per se, made of a viscoelastic oil-based plasticized polymer composition comprised of one or more hydrogenated poly-isoprene/butadiene (“SEEPS”) polymers and/or an intimate melt blend admixture of block SEEPS copolymers in combination with various polymers of poly(styrene-butadiene-styrene), poly(styrene-butadiene).sub.n, poly(styrene-isoprene-styrene), poly(styrene-isoprene).sub.n, poly(styrene-ethylene-propylene), poly(styrene-ethylene-propylene-styrene).sub.n, poly-(styrene-ethylene-butylene-styrene).sub.n, poly(styrene-ethylene-butylene), poly(styrene-ethylene-propylene).sub.n, poly(styrene-ethylene-butylene).sub.n, polystyrene, polybutylene, poly(ethylene-propylene), poly(ethylene-butylene), polypropylene, polyethylene, polyurethane and silicone, and a plasticizing oil. The gel printing plate of the present invention has an extremely sensitive surface and will imprint any texture on which it is placed.

[0014] The resulting gel printing plate made in accordance with the present invention results in the gel printing plate preferably having a soft, smooth surface with a gel “feel” that is capable of accepting a wide variety of paints and inks. The most preferred paints for use with the gel printing plate of the present invention are acrylic paints, which can easily be cleaned from the printing plate with mild soap and water, followed by rinsing and gently patting the printing plate dry with a paper towel. When using acrylic paints, it is not necessary to clean the gel printing plate between prints. Interestingly, a paint residue can contribute to quite surprising and pleasing aesthetic printing results.

[0015] Oil-based paints may also be used with the gel printing plate of the present invention, and can be easily cleaned from the gel printing plate by rubbing the surface of the printing plate with baby oil and wiping clean with a paper towel. The gel printing plate is subsequently washed with mild soap and water, rinsed and patted dry.

[0016] If the gel printing plate is constructed to include a supporting substrate on which the viscoelastic gel is placed, any such substrate should preferably be a smooth, flat, non-porous barrier surface, preferably made of Teflon® (polytetrafluoroethylene) or glass.

[0017] The inventive method for using the elastomeric, or viscoelastic, gel printing plate of the claimed invention includes the steps of applying a thin layer of paint (preferably using a brayer or paintbrush) to create a design. Paper, for example, is then laid over the painted gel plate and may be rubbed by hand for transferring the paint to the paper, thereby resulting in a printed image. The advantages and attributes of this inventive method include the following: [0018] the gel printing plate's soft, smooth surface accepts a wide variety of paints and inks; [0019] the paint or ink releases easily under minimal hand pressure for an effortless transfer print; [0020] the gel printing plate stores at room temperature and is ready for immediate use; [0021] the gel printing plate is always ready to print with; requiring no special preparations; [0022] the gel printing plate is durable and reusable; and, [0023] the gel printing plate of the present invention is readily able to be cleaned.

[0024] As a result, the present invention provides a reusable, durable gel printing plate designed for artists' monoprinting techniques without the need for a press or other pressure tools. The inventive gel printing plate replaces the need to prepare natural gelatin plates for similar printmaking processes that artists have conventionally used.

[0025] While only several embodiments of the present invention have been shown and described, it will be obvious to those skilled in the art that many modifications may be made to the present invention without departing from the spirit and scope thereof.
