1. Rough Sketch
This is where the designer's creativity works the best. At the end of the process, the design is captured on a computer and makes the design more bold than its actual shape.
2. Rough Carving (using carving machine)
A carving machine does the first rough carving. At this stage, its shape is expressionless and the rim is uneven.
3. Finish Carving
This process requires a designer's skill set. The sealing surface is carefully carved to infuse spirit to the Hanko (Seal). For In-So-Tai, it makes its rim thinner and leaves trim characters for the finest possible embossment.
