Hi all -
Back to laser engraving on marble/granite for 'minute, if you don't mind. I engrave photographs on solid black marble/granite tiles that I buy at Home Depot. - the detail turns out fine, but cannot for the life of me get the pictures "brighter"! (think it's been suggested higher speed/lower power - doesn't seem to make 'difference for me.) Is the object to cut through the dark "cap" into the lighter interior of the tile? Also: I learned 'bout "Rub 'n Buff" from you all - tried the silver, today. Seems to make the picture brighter. But, not sure it would hold up to outside use of these tiles . ?? Tomorrow, plan to try different speeds 'n powers - again! But any suggestions you have - or, experience with - would be much appreciated. (will try attaching picture of one I did 'while back - BTW the lighting 'n flash make it appear much brighter than it actually is.) So ... eager to hear ideas ... thanks.
Bill
