Bold Black Board That Makes Every Project Stand Out

Rainbow Spectrum Board A3 220gsm Black gives artists, educators and designers a rich, uncoated matte surface that commands attention in any display or presentation.

At 220gsm, this heavyweight board offers the rigidity you need for posters, signage and layered craft builds without sacrificing ease of cutting or shaping. The deep black matte finish heightens contrast against bright colours, metallic inks and sharp white text, making it a go-to choice for classrooms, studios and office presentation work alike. Acid free construction resists yellowing over time.

The uncoated surface accepts a wide range of mediums - paint, markers, pencil and adhesives - with consistent results. Each pack contains 100 A3 sheets, giving you ample supply for ongoing projects, bulk display runs or school art programmes.

Rainbow Spectrum Board is a trusted name in Australian classrooms and creative studios. Stock up and keep your projects looking sharp from the first sheet to the last.
