Recreating pulp, ben-day or four-color style

While working with the post process volume I came across a set of settings that in-editor looked just like a pulp magazine cover, which I enjoyed and built a game around.

Once I packaged it, the high contrast and saturation stayed the same but the dot-matrix look to the shadows and colors was smoothed out.

Normally that’s a good thing, but in my case it created a problem. Has anyone found a way to have the dot matrix, ben-day or four-color print look in a packaged game? Maybe someone that had rhe opposite problem I do? It doesn’t need to perfectly emulate the style. An approimation is fine.

Some visual examples of what I’m talking about:
