Post by: Findecanor on Fri, 16 August 2013, 18:14:56: Ah. Then I think that you would need a larger, sharper image. That one is quite small and blurry. I think that the engraving would need sharp edges to give a good result.

BTW. I edited my post to post an edited image above.

:D Thank you!
I know it need a sharper image, but the available engrave is very small, i think is 15mmx10mm :blank: so i think should use a small picture

If that's the case then surely your friend can provide you with a larger resolution picture with any colour background you want?

I used Gimp, which his free. The interface is a bit different, but there should be a version that looks and feels more like Photoshop.

Post by: TheSoulhunter on Sat, 17 August 2013, 16:16:24: Upscale -> Upload to Vectormagic (the first few processings should be free iirc) -> Download generated vector file -> Tweak in Inkscape (free)
EDIT: Or wait for MOZ :D
