Pure ink is a painting software in Ink Art and developed with the mission to bridge the gap between this traditional Asian art form and digital media. Pure ink simulates realistic ink diffusion and water-based coloring effects on paper. It is also capable of visualizing various strokes produced by Chinese brush.

Pure ink中文取名離心一墨。當中的離心意指運動之力,然則力在天道中恆常以一對的形式存在,離心一墨實乃向心一墨。今以傳統水墨為此心之源頭,立足於此,乘數碼時代之利,以離心之勢拋擲水墨創造的種子,心念源頭,足下追新拓遠。

Pure ink won Certificate of Merit in the category of Interaction Design at the 2021 Hong Kong ICT Awards (香港資訊及通訊科技獎 Pure ink is opened to the public and assists ink artists for their creative projects in digital media. This project welcomes donation for sustainable development in future.
