Stamp, Stencil and Badge Factory

1. Sharp black and white images and a minimum of border are best.
2. Use image format .png or .jpg with resolution 150 px for clean edges.

Print and finishing your stamp

Stamps may be printed in standard PLA or ABS (flexible material does not work well).
Provide a grip and backing to your stamp by gluing it onto a block slightly larger than the stamp with white or plastics glue.
To finish the stamping surface, sand with P120, 150, 180 then polish with P240 grit.
Make sure to sand the stamping surface flat and parallel to the table.
To use and get best results from your new stamp, place a soft tissue under the paper.
Use a helper triangle or guide to keep the stamp straight on the work.
Feedback and pictures of results are always very welcome. Get in touch with me via Facebook or G+.
Happy stamping and make lots of gifts or stamps this year!

CandleCaster works best with a modern browser such as Mozilla Firefox or Google Chrome.
