Unfortunately the jpg isn’t clean enough (in GF it’s VERY grainy with dots everywhere).
My bitmap is MUCH cleaner/crisper than the jpg, but the letters just aren’t angular enough (got somewhat rounded in the process). (the engraving will be approx. 3.5")
My bitmaps usually come out GREAT. But this one is awful - pretty sure it’s my settings but can’t get it right.
Thank you, @jestelle and @evansd2 I’ll play around with these (while requesting a higher res. image).
@evansd2 Traced your png in Inkscape and it looks almost identical to the one I did (but eagle is slightly better), so I’m thinking it has to be my Inkscape trace bitmap settings? Going to look up what the default settings usually are and try to reset them.
So, the rounding is because inkscape’s tracing is an approximation. It’ll never be perfect.
As I said, the fix I did should resolve your dots issue, not the resolution issue.
One trick I do sometimes that can make things a bit better is to resize the image in inkscape to be very large (low res and all), and then trace it when it’s bigger. After that, I shrink the resulting trace back down to desired size.
Do you need to cut or score some part of this design? If not, you don’t need to worry about tracing anything. You can upload images to your Glowforge and engrave them. You don’t need vector artwork to engrave. You even get additional settings and speeds not available to vector artwork.
As for me, I say don’t engrave this version unless you’re desperate. 3.5" is still in the “hand held” class, and that means people will be getting a good close look at it. I’d shoot for at least 300dpi resolution, if you can get it. Ideally, you’ll get a source image from the creator that is at least about 1000x1000 or higher.
@dan84 and @jestelle I think it’s just that the jpg is such a low res. that it looks super grainy (on screen, anyway) even when cleaned up…but maybe I’m overthinking it, and it will come out ok.
I will do a test - one of the jpg/png and one of the svg - and compare.
I have found Gimp to be best for me, especially in cases of jaggies,. It will still round corners (as they are rounded by pixels anyway) but you can get a good mask and set the mask to a path and then export that as an SVG.
Once in Inkscape if a corner is too round, if highlighted, you can double click in the middle of that curve, and then double click on the leftmost “curve” button and it will be a sharp angle. You can then grab the midpoint to the next node and make the fine adjustments. It is a good thing to practice with Gimp and Inkscape to know where stuff is when it is not a time crunch first,
