They are not. In litho printing there was a range offset>screenless
offset>collotypie that represents that gradual change to continuous tone
printing quite good. Conventional rotogravure comes very near to continuous
tone printing, modern versions of it that rely on electronically engraved
cilinders adapted halftone screening partly in the process but never
totally. So these aren't exclusive systems. The same is possible in inkjet
printing.
Ink bleeding isn't always a negative issue in printing processes,
conventional rotogravure partly depended on that effect to get a continuous
tone result. No dot size differences in that proces but more or less ink per
spot. Transparent ink of course.
