White ink digital printing
        
        Recently, a water-based white digital ink has been commercialised     allowing to print a white background directly onto dark textile materials     (T-shirt). Together with the already available water-based CMYK direct ink     series, this offers the possibility to realise a coloured print against a     white background on dark textile substrates.     Thanks to their excellent properties (such as a good colour fastness     against washing, light and bleaching), the applications of these inks are     mainly clothing-oriented.
