Iphone 3G white/back engraving setting

[banhbao]

Hi,
I would like to laser etch my iphone 3GS with black/white cover but I don't know the setting for it. I"m using epilog laser 45watts.

Could someone who has done that before help me with the setting?

Thanks,
Brian

its plastic, so we'd try maybe 40% power 100% speed

Thanks, I'll give it a try and send out the result.

I'm using an epilog 35 watt machine. I tried this today at 40pwr 100spd. It just melted the plastic. I got no black mark at all. Please post if you know how to do this. it was an iphone 3gs, 32GB, the case is all white

If it's just plastic, you'll never get a black mark. To get color on plastic, you need to mask and color fill (or just color fill if you are less sloppy than I).

The cool color changes you see on other gear is due to the painted or anodized metal case. To get black on unpainted and unanodized metals, you will need Cermark or something like it. There are now colored versions of Cermark out but I've not tried them.

I have a 30W Zing and I did two runs on a white iPhone. First was 100% speed, 60% power and second was 100% speed, 25% power. It came out yellow but didn't look too bad (make sure your image doesn't have any shades in it for better results).

I did a black iPhone with 100% speed and 50% power and it came out very nice.

thanks for sharing your results, the zing will be a popular cutter so people should share settings
