Hello :
We're having a dilemma raster engraving silver and gold 'anodized' aluminum. We've coated it with Cermark LM-6000 and continue to get a whitish raster impression? Isn't this product supposed to produce a black image on anodized aluminum? BTW, I am using a 35+/- Watt machine that does a beautiful job with Cermark when it's used on Stainless Steel at 100% Power/9-10% Speed. Also, our question ONLY relates to gold/silver aluminum, naturally we get a white and very desirable raster with red, blue, black etc. anodized aluminum.
Thanks in advance for your help or advice,
Regards, JB Lynn
