Firstly Diptrace says that the bottom color must be a reduced color opposed to the top color. Mine are the reverse way around - how do I change this? I am new to using Gerber files, looking through from the top side, the bottom layer looks the same. Do I assume that the Greber file for the bottom layer must NOT be "Mirrored" am I correct? Only text on the bottom must show through in a reversed mode.
I am 83 years old and have a problem understanding the technique of Gerber files.
