Things you should know about etching metal.
The most important part of the process of etching metal is the preparation of the photoplate.
The drawing must be properly dimensioned based on the metal and its thickness. The drawing must be done using a vector graphics program. The printed drawing must be perfect – black must be totally black and white without spots.
