When you mentioned about printing onto fabric, the thought is whether fabric can be washable after the printing? It is preferable that the ink stays. Can you please comment which of the following type is the ink? 1. Water resistant : a few drop of sprinkle water doesn't dissolve the ink. 2. Water proof : Submerged into water and the ink will not dissolved. 3. Washable : Subjected to detergent and the ink stays on.
