Rubber Stamp Lessons Learned

I need a rubber stamp with my name and title on it to help speed some documentation at work. I picked up a sheet of “low odor” rubber from Johnson Plastics and got to work. The item number is RUS001 if anyone is interested.

The first thing I learned was that “low odor” is a subjective term. VERY subjective. Other than that, the material itself was good and consistent. I did an “R” (and then flipped it horizontally) to test it on inkscape, and it was pretty easy. I used two different colors, and the GFUI wanted to engrave them both. Since they were different colors, the GFUI wanted to engrave them in different steps, so I just told it to ignore the step where the “R” itself would be engraved, leaving only the other step which cuts everything BUT the R.

For settings, I found another post here from earlier and found the settings worked pretty well. I used 70% power at 340 speed, with two passes. To cut, I used full power at 200 speed, and I got a nice clean cut.

Attached some photos so you can see how it came out. Make sure you are well vented, or maybe try the “No odor” variety of material, because it smelled like, well, burning rubber…


Nice depth! :grinning:


That depth is perfect! Nice work! Thanks for the settings and item info. We really should have an easier way to document those.


That’s mainly why I posted. I had some difficulty finding settings to use as a starting point, so I hoped others would find it helpful. I mean, who doesn’t need a stamp?!


looks amazing, is it really necessary to cut that deep?

I honestly don’t know. It’s my first stamp :^)

Dang, so nice and clean! Well done.

Very nice job!

Now, if in the future you want to make stamps with really thin lines, keep in mind that you would need to create a greyscale image with a ramp to white (unengraved surface) so the base of the figure (next to the engraved area) would have some support. Otherwise the thin parts would wiggle when you tried to stamp them. I hope this makes sense.


It totally does. I’ve actually used the exact same technique to create what you just described. I didn’t post it here because it has a lot of personal detail, but it’s done without the type of gradient support you describe. If it wobbles when I stamp, I’ll try the greyscale ramp you’re describing and update the post. Based on Leahgee2’s input above, it may be that I don’t need to cut quite so deep as well. Nothing teaches so well as failure :^)


And for those who want to learn from other people’s experience as well, I’ve linked to posts below. Note that settings in earlier posts may not be applicable because of changes to the power settings over time. (Links to ‘Beyond the Manual’ do not display the same way as links to ‘MOAG’.)




In testing my real stamp (the one with all my personal details on it), I found it did wobble a little, but with even pressure it worked very well. That said, I’m going to cut another this weekend with the font bolded so the letters themselves are thicker. With this particular rubber anyway, I do not feel the gradient support is necessary. Your mileage may vary.

Thanks so much! My next project will either involve rubber stamps or wood block printing. This is helping me lean toward rubber!

Well done! Just received my Glowforge recently and am interested in making some rubber stamps. What is the best design software for rubber stamps. Are there any tutorials available to help me get started?

Thanks so much!

Many people use either Adobe Illustrator or Inkscape. As Illustrator would run me $20/month, I use Inkscape.

Thanks for the info. Learning Inkscape now.

Thank you for the settings.
All worked perfectly!
2 passes are essential!

Made that to my sister in law to stamp her kids school books!

It says: “This book belongs to blah blah and blah blah”


Ooh! Like the spiral text! :grinning:


long thread with lots of info. What material and settings did you end up using?

Hi there, I’ve used this material:

And used the settings he mentioned, worked perfectly.
For the engrave and cut I did two passes ! (the cut just to make sure) or you can try reducing the speed of the cutting part.


Power: 70%
Speed: 340 speed
Two passes

Cut :
Speed: 200
Power: Full
Maybe two passes.


I see that though it’s Chinese origin, they say item location is GB, and a delivery in three days.
Is that your experience, with a quick delivery ? I’m assuming your UK based because of the link !
