Great work! Recraft V3 does very good vector images. I wonder if you could use the SVG the model outputs directly in the plotter. Would save you a lot of time.
For use on a plotter, the line art specifically needs to be a stroked path, rather than a filled path, and so for tracing you need centreline tracing, as discussed in the article. So you probably get absolutely no benefit from taking SVG—you’d need to turn them back into raster and trace them properly.
Looks like a fun project. I would love to get into pen plotting someday.
Have to say the text bothers and intrigues me… digital fonts that try to look like handwriting are already in the uncanny valley, and then you loop it back into physical media with a pen plotter. It could almost be an art project in its own right, exploring layers of going back and forth between physical and digital media to produce a seemingly mundane paper with some writing on it.
I remember once seeing a presentation about someone making extensive use of ligatures to create a very realistic hand writing effect. I think it was that an "e", for example, would always look different depending on the preceding letter, even though it was not a real ligature case per say. It's a huge amount of work but I remember the results being very convincing.
For me, pen plotting is a lot of fun. There is something so satisfying in bringing digital work to the physical world.
As for the text, I have it on my todo list to create a few single line fonts, for some time now. The obvious one is my own handwriting, ideally with some randomness built in. I would like others to be less conventional to sprinkle them in my drawings, or like you mentioned, to create some pieces that are text only.
Lovely project! A little trick against the smudging with some paper is to apply a thin layer of hairspray to the page after plotting/printing and then letting it dry for a bit. We do this for riso prints at our universities printshop. Should work just the same with pen plots.
About the cleaning up phase: the author cleaned up the bitmaps before the vectorizing stage, and that included separating lines.
In my experience it's a little bit easier to clean the vectorized results by removing unwanted points, because those are easier to see than line connections that may or may not pose a problem later. (But to each their own.)
Actually that's my usual approach, but you should see the vector output from these. I tried doing it and than went back to cleaning up the raster images.
Combining the two ideas, "hand drawn" animation flip books could be neat. Start with a video, convert frames to a drawable vector, draw each frame with a pen plotter, assemble the flip book

I haven’t used it personally, but examining some in https://www.recraft.ai/community?imageParentType=vector_illu..., I presume they’re producing raster images, and then auto-tracing. I looked at a few of the line-art samples they had there, and https://img.recraft.ai/--CWuHOOd2OaTTKRrIUsA-2nRJt-52M8NnXRt... has all kinds of artefacts that are just like autotracing tends to produce.

Loved this.
Love to build. Build to love.
Reminded me of Wordle and a few more projects like https://www.robinsloan.com/notes/home-cooked-app/
It's always wonderful to see projects we build for love. Haha. Cheers OP.
Thank you, you made my day!

Amy Goodchild has done some incredible work in this vein, involving pen plotters even. https://www.amygoodchild.com/blog/cursive-handwriting-in-jav...
I'm not sure it was her but this is brilliant anyways. Thank you for sharing the link!
This is awesome! I’ve seen it but forgot to bookmark it, thanks for sharing it again.

Curious to know what pen plotter was used here… didn’t look like article mentioned it.
I’m a big fan of Dan Catt and his work with generative art and pen plotting.
The author mentioned that the maker of their pen plotter is evil mad scientist, so it's likely they're using the AxiDraw
That is correct. I use AxiDraw SE/A3 and I love it. One of the best purchases I ever made.

Thanks for the tip! Does it make paper shiny and stiff?
Excellent project, congrats!

Love it - I wonder if you could create a animation book this way cheaply, see a moving image as you flip through it
You're in luck: https://news.ycombinator.com/item?id=42918902
Amazing, this is why I visit HN :D

Sure, I think the hard part is creating hand drawn animation. If you can draw or generate it, the rest is fairly straight forward.
I have an idea for somewhat different flip animation, stay tuned :)
Great outcome and write up, thanks for sharing!
Super cool and it looks fantastic!
I've been wanting to do something with a plotter, thanks for the tip about center line tracing
Amazing work! Thanks for sharing
I just can't enjoy art anymore in this brave new world.
I miss my pen plotter.
Inspiring! Great work
