Art Spectrum Colourfix Optimum Board is a high density archival and acid free foamcore board, hand screen printed with Art Spectrum Colourfix Primer...The secret that separates this board from all others is a super thin layer of Aluminum within the board that prevents warping and helps provide this substrate’s lightweight and sturdy characteristics.

Colourfix Optimum Board has a robust toothy surface that will hold layers of pastel without the need for fixative, allowing the velvet bloom and vibrant colour of pastel to be preserved.
