VDT | Variable Dot Technology

VDT is a functionality of the piezo print head that enables the creation of ink drops of different sizes, allowing smoother gradations and higher detail. The larger drops are a combination of small drops jetted with different speeds; when reaching the media, they have merged into one larger drop.

The advantage of VDT explained

Variable dots

With different dot sizes, a much smoother gradation of colour tones is achieved, improving the overall image quality. In addition, smaller details can be printed further increasing the image quality.

Normal dots

The production of gradations with a single dot size will result in a less smooth and more grainy effect.
