To transfer the rubber stamp, you can lay sulfuric acid paper on the desired pattern and trace it, then stick this side on the rubber stamp and scrape it with bus card and coin. Or use transfer water to wet the printed pattern, and then stick it on the rubber stamp and scrape it with a hard thing.
We usually need to transfer the desired pattern to the rubber brick when carving the rubber seal. There are two methods of transferring the pattern. They need sulfuric acid paper and transfer water.
The first is to print out the pattern we need, then lay a piece of sulfuric acid paper on the pattern and describe the pattern on the paper, then paste the pattern we have drawn on the rubber stamp, and then scrape the sulfuric acid paper repeatedly with things such as bus cards and coins.
The second is to print the desired pattern first, then wet the printed paper with transfer water, stick the patterned side of the paper on the rubber stamp, and scrape the paper repeatedly with hard things.
