Very different, you could train one to be really good at making signs, but you'd need a huge dataset of images of things with text and transcriptions of the text in the image.
Otherwise you just get this emulation of the general idea of text that's contained in images that look like the thing that you're asking the AI to replicate by smooshing all the similarly tagged images together.
I don't know enough about this stuff to know how closely related those two things are, an AI that does images and one that does text.
