I use a marking methods machine,I use the heavy duty green stencils,not the gold.I set the machine at 1/2 power,touch the pad to the stencil (lightly)2-3 seconds,lift and repeat,about 12 times.BTW before you start,put the felt on your hand pad,soak w/ electrolyte,then dab it on a dry paper towel until it barely shows a damp mark,then proceed,and hopefully you will have better results.
