This project prints test pattern for F1 on black metal business cards.
The purpose is:
1. a power reference for future comparison
2. select the lowest required power
3. chose power/ speed setting to provide the best dynamic range for grey scale
Verison 2_0 - Useful dynamic range of Blue Light card increased. QR Code for xtool material added. Burn time added.
This is a test pattern for F1 printed on the xtool Black Metal Business cards. The Test Pattern can be use for:
The xtool Black Metal Business Cards are painted. Some residue remains after the burn. Washing the cards post burning is recommended.
