For direct digital printing directly onto fabric, only cotton textiles are used. The more natural the fabric, the brighter the pattern. Dense fabrics are used for roll digital printing on fabric: linen, fabrics for bedding, diagonal, cotton, canvas, calico, poplin, lacoste, tight knitwear, as well as non-woven fabric, spunbond, and others. Direct Digital Printing Fabrics Must Be Tested.
