To keep stamp ink from smearing, you can use a few different methods. One is to use an inkjet printer to print your stamps. This will prevent the ink from smearing because it dries instantly. Another method is to use a clear embossing powder on your stamps before you stamp them. This will also help to keep the ink from smearing. Finally, you can use a sealer on your stamps after you have stamped them. This will create a barrier between the ink and the paper, preventing the ink from smearing.
