Quoted from Aurich:
With the new digital printing and no screens in theory there's no longer a need to do everything vector, high rez raster art should be just fine. Which means a scan and cleanup could be done much easier than a full vector redraw.
Assuming Kevin agrees with that.
I am guessing cut lines would still need to be vectors. I'm curious how one would approach raster art for something that was originally screened.
I'm also now curious how the digital printing of the vectors works. Does it accommodate what would effectively be slight translucency in a layer so that when it's overlapped over another that it creates a new color?
If I'm vectorizing plastics that were originally silk screened, I only have to concern myself with identifying the main colors and I have to ensure that any overlaps are captured in each color layer, and the silk screening process will take care of any resulting colors that come about from multiple layers overlapping.
If I'm producing a raster image of those same plastics, I now have to be concerned with the resulting color from any overlaps. I suppose a layered raster image could be made.
Let's say I had a yellow layer overlapping a blue layer. Flattened vector art with no translucency would just show that as yellow, whereas a layered silk screening would result in a green (perhaps more so when light shines through). So if I'm producing a raster image, I'm losing the concept of depth from the layers, and I'm also potentially not capturing (or misrepresenting) the mixes that result from them.
I'm am an amateur in image processing and printing, so I don't really know how a lot of this works, and could be wrong in my assumptions.
