Photosensitive rubber pad for seal pottery, calligraphy, and painting, high-quality black and grey sheet in 7mm, 4mm, and 2mm thicknesses, measuring 330 mm x 110 mm.
Photosensitive Rubber Pad for Seal Making in 7mm, 4mm, and 2mm Thicknesses

This photosensitive rubber pad serves as a dedicated material for artists, crafters, and pottery enthusiasts creating custom seals, stamps, and decorative elements. Supplied as a single, whole sheet measuring 330 mm by 110 mm, it is designed for use with light exposure techniques common in photopolymer stamp creation. The product's key feature is its availability in three precise thickness options – 7 mm, 4 mm, and 2 mm – allowing you to select the relief depth suitable for your specific project in calligraphy, painting, or pottery marking. Its black and grey colouration is part of the light-sensitive formulation, ready to accept your designed pattern. As a single-unit supply, it provides the base material for one comprehensive project or can be divided for multiple smaller designs.
Features and Construction

The pad is constructed from a single piece of photosensitive plastic, formulated to react to light during the stamp-making process. Its dimensions and thickness options are its primary measurable specifications, defining its application potential.
Material and Build
The sheet is made from a plastic polymer that is light-sensitive. This property is essential for its intended use in creating seals and stamps through exposure, where light hardens the polymer in specific areas to form a raised design. The material is supplied in a black and grey colour, which is typical for such photosensitive sheets. Its construction as a single, solid sheet means it arrives ready to be used with your exposure unit or light source, without any assembly required.
Size and Practical Fit
The pad's overall size is 330 mm in length by 110 mm in width, providing a substantial working area. You can use the entire sheet for a large stamp or cut it down to create multiple smaller stamps or decorative pieces. The choice of thickness – 7 mm, 4 mm, or 2 mm – directly influences the height and depth of the final stamped impression. A thicker pad like the 7 mm option allows for deeper, more pronounced relief, suitable for pottery or heavy ink applications, while the 2 mm version offers a shallower profile.
Uses and Placement

This product is specifically aimed at crafts involving custom impression-making. Its applications are tied to techniques that use light to cure or set a design into a polymer material.
Event or Professional Use
For professional artisans, potters, or small businesses, this pad can be used to create custom seals for branding pottery, authenticating artwork, or producing consistent calligraphy stamps. The ability to choose the thickness allows for tailoring the stamp to the medium – a thicker seal may hold more ink or clay impression detail. A single sheet can be used to produce a master stamp for repeated use in a studio or workshop setting.
Everyday Home Use
Hobbyists and craft enthusiasts can use this pad for personal projects such as creating custom stamps for scrapbooking, handmade card decorating, or personalising homemade pottery. The 330 mm x 110 mm sheet size means there is enough material to experiment with several designs. The different thicknesses let crafters explore various visual effects, from bold, deep impressions to finer, more subtle details in their painting or calligraphy work.
Benefits and Buying Value

The value of this product lies in its specificity as a ready-to-use material for a niche craft technique, with clear options to suit different project requirements.
Reuse and Low Maintenance
Once exposed and processed according to your equipment's instructions, the created stamp or seal is a durable tool that can be reused repeatedly. The sheet itself requires no maintenance prior to use; it should simply be stored away from strong light to prevent premature exposure. After creating your stamp, no further care is needed for the pad material itself, as it becomes part of the finished tool.
Why Choose This Product
This photosensitive pad is a practical choice because it provides the specialised material needed for light-based stamp creation in a convenient, single-sheet format. The availability of three thicknesses is a clear differentiator, offering tangible control over your project's outcome that many standard sheets do not. Its defined size of 330 mm x 110 mm helps in planning designs and calculating material needs accurately, reducing waste. For anyone engaged in seal pottery, calligraphy, or painting requiring custom stamps, this product delivers the essential component without unnecessary complexity.
