How do I engrave text from a jpg?

I am trying to engrave a nameplate on plastic. The file I was given is a pdf, which I converted to a jpg. I am going to post some pictures. I hope they show up right.
Here is the jpg


The problem is this is what it looks like when I preview it.

It has a bunch of dots. I did a little research and saw some people said to trace the image, so I tried that, and got this, which looks ok.

Until you zoom in close.

The vectors look off. So I adjusted the threshold and it improved, but not enough.

I saw that some people mentioned using Inkscape, which I have, but don’t know how to use it to fix this.
Any suggestions?

When I do this I just use the text option and type it with a font that’s close. Then I size it to match the photo. Use the trace for objects you can’t type.

In fact that’s simple enough to just freehand. just a few minutes then using the duplicate feature.

I thought about just drawing it out, but there are 9 of them, so I figured if could have it engrave from jpg or pdf, it would be quicker. But if there isn’t a fairly easy solution, I’ll just make it from scratch.
Thank you

Can you post your PDF here for us to see whether we can provide a better workflow?

How do I do that?

You can either drag the file onto the text area when you’re replying or use the ā€˜Upload’ button:

image

The forum is very limited with the file types it allows you to upload but you can ā€˜fool’ it by appending ā€˜.txt’ to the file name. e.g. ā€˜myfile.pdf.txt’.

Here it is
SES 1 Label.pdf.txt (700.3 KB)

Ok, tried opening in various applications with varying degrees of success/failure. I ended up opening it in Inkscape then exporting as SVG (see attached). To download it just right-click the image and select ā€˜Save Image…’ (or similar menu item provided by your browser).

Hope this helps.

Or a PDF if you prefer:

Awesome. I think that will work. I have Inkscape, so I will try redesigning the other nameplates in there and export it as .svg file.
Thank you so much

Glad to be of help. FYI LB will import PDF directly if the PDF isn’t using any unsupported features.

How did you do this? I need to make some changes to it because some of the lines are not closed so LB can’t fill them. Plus, I have 8 more to do after this one. I have Inkscape, but I’m just not sure how to use it to achieve the results that you did.
Thank you again.

Open Lightburn. Click file, import. Select your PDF file. I just did this. It actually imports well.

@Marcus_Wakefield suggestion above

When I processed it previously I ungrouped everything before doing the export but I’ve just done a test and found that this step isn’t necessary (with this file at least - another file might be different).

Just open the PDF in Inkscape then export as ā€œPlain SVGā€. That’s it, you should be able to import that into LB.

I get nothing when I try to import the original PDF into LB. CorelDraw, Affinity Publisher and Adobe Acrobat 9 either failed to import any of the content or some was missing.

I removed the .txt off the end and did the import. Here are the results. I had to change the 3 blue lines to a different layer.

I can’t import the original pdf either. I got nothing when I tried. I get nothing when I import it into Inkscape. If I change it to a jpg, it imports, but then I have the pixel problem from my original post.

Can I just confirm that you are saying that you can’t import your original PDF into Inkscape?

That is correct

I’m using Inkscape 1.4. Which version are you using? BTW I’m using ā€œOpenā€ rather than ā€œImportā€ in Inkscape although it brings it in whichever way you use. Open works a bit better though.

Do you get an error when you try to open it in Inkscape?
