I think these images were made by few artists, because the style is very distinct and recognizable. I still encounter these clipart pics on signs of crappy cafes and shops. Made of plotter-cut adhesive film, these pics look gorgeous.

AFAIK, PDF is mostly a container for PS with compression and better handling of fonts (BTW, can fonts be embedded in PS? How fonts are sent to printer?). Still, both formats are too much printing-oriented. Reading documentation in PDF on co

But maybe such "binarization" throws out information which might be useful? ZX Spectrum generates rectangular signal, after writing to tape and reading back, it becomes heavily low-pass filtered. So, I thought, if we take typical
