Hewlett-Packard: White ink for digital sheet-fed presses

ElectroInk White is available for the new HP Indigo 7500 Digital Press and follows the introduction of HP ElectroInk White for commercial and packaging applications on HP Indigo press 5000 and 5500 models. The white ink may be used to print white on white, which creates a subtle, almost watermarked, appearance, which has security applications, especially when used with variable-data printing.
