Dyes inks are either natural or chemical derivates, and the
advantage it has is that it’s formulation is low
cost, ease to use, raw material easily available, and
generally non-toxic in nature.
The disadvantages of dye base are its tendency to fade out
in the sunlight and slow absorption into paper. Therefore
sharp printing is not achieved by this ink. Therefore drying
agents are added to this to make it quick drying.
