How to Use the Stamp for Clean Impressions
Follow these steps to achieve sharp, consistent results with your thumbprint stamp.
- Prepare the Leather: Dampen the leather slightly with a sponge or spray bottle. The surface should be evenly moist but not soaked. This softens the fibers and helps the stamp create a clear impression.
- Position the Stamp: Hold the stamp vertically over the desired location. For a straight lined pattern, align the horizontal lines with your intended design. Use a ruler or guide if you need a consistent border.
- Strike with a Mallet: Using a rawhide or nylon mallet, strike the top of the stamp firmly and squarely. One clean strike is usually enough. Avoid rocking the stamp, which can blur the impression.
- Check and Repeat: Lift the stamp straight up to avoid smudging. Inspect the impression. If it is too light, re-moisten the leather and strike again. Repeat to create a pattern, spacing stamps evenly.
Care and Maintenance Tips
After use, wipe the stamp clean with a dry cloth to remove any leather residue. Because it is stainless steel, it resists rust, but storing it in a dry place will keep the stamp head in top condition. Avoid dropping the stamp on hard surfaces, as this can damage the CNC-milled head and affect impression quality.
