    How-to: Laser engraving photo

    I do a lot of engraving on acrylic on a Trotec Speedy 300,and I use a different method. I don't even bother taking out the backgrounds(personal choice). My first step it to convert to grayscale,then I go 300 for the resolution,then I go to adjustments>brightness/contrast and usually make both of those 25,but this can change depending on the picture.Next I go filter>sharpen>unsharp mask. I usually go amount-500%, radius-3,and keep threshold at 0.I don't even convert to bitmap,I just save it as one. The laser settings are definitely going to depend on your laser,and from what I understand,that goes for each individual laser even if they are the exact same model.I'll have to get some wood and try out your settings. Thanks.

    We have a the Speedy 300(I'm actually sitting right next to it as I type) and I know that it was only about $24K according to my bosses.The only thing is that I wouldn't be able to fit a full sized kitana into my machine.
