Exactly that. I just googled "Demon Woodcut" or something lol. Then I used this website to convert it to a vector:
https://www.autotracer.org/
Once converted to a vector I made a few small changes in Affinity and that was that.
It's worth noting, you can do a full Tayda PDF in Affinity alone. I upload the drill template, then I do my design around that (has to be vector art of course). Then I convert text to curves under the Layer menu. Then I export as PDF - Digital High Quality and I make sure that it says nothing will be rasterized. If something will be rasterized and I don't know what, I'll export it, then open it in Affinity and zoom in on everything and see what's rasterized. One annoying thing, is if you use ANY layer effects (such as outlines) it'll rasterize those layer effects on export. So if you NEED to do layer effects, export your rasterized file, then use that rasterized file with that autotracer site I mentioned above, then open BACK into Affinity. Then you can make additional tweaks from there. I find vectorizing will mess with fonts, so you may want to make your design, hide your fonts, then export, then vectorize, then import again, then show your fonts again, so your fonts retain their tightness/sharpness.
