Can it be more realistic to paint the inkpad on the color-printed seal?

Of course. A seal is stationery printed on a document to indicate identity or signature. Generally, seals are stained with pigment before printing. Those that are not stained with pigment and will appear concave and convex after being printed on a flat surface are called steel seals, and some are wax prints printed on wax or wax or envelopes. Made of jade, metal, wood, stone, etc. Seal is one of the representatives of China traditional culture.
