My favourite material for printing is Pandora Canvas 380 gsm 100% cotton and matte finished canvas. It allows framing without glass in a clean modern way. Printing is done with enough white border for stretching around a frame with a box border of choice. It is perfect for either colour or black and white production.
The fine art paper I use is Ilford Galerie Prestige Fine Art Textured Silk, which offers a 25% cotton and 75% cellulose capable of delivering stunning contrast and sharpness with a wide colour gamut. Also perfect for black and white production.
