The Indian ink is very important because it maintains a uniform consistency and color after adding water.
There are different techniques used: “coloring on washed paper” which overlaps the colors that are being used so that they can easily overlap other colors to form the effects that are desired. This technique allows the colors to expand when drying and produces an effect that seems to elongate the design. The “paintbrush color” is used to create similar effects as the watercolors but can also create more definition by using the pen desired to outline.
There are different types of tips for the pens: the calligraphy tips that are resistant to the various pressure applied , the bamboo tips create a denser line, the goose tips create a form that is very thick. The best paper to use is the rough F4 paper.
