need help figuring out color separating/trapping/choke in photoshop
hey guys, I have a 10 color screen print I need separated. the colors are all on separate layers, but when I colored it I over lapped quite a bit an am now trying to do the trapping so the colors don't show thru under the other ones. is there a way to do it where I can select each color and delete it on the upper darker colors without getting that "flash" white border around the color? or would it be easier to flatten all the colors and figure out a way to just separate it from there? I'm using cs5 by the way. any help would be greatly appreciated...
and say if I have a light brown, with dark brown shaded on a layer above it, do I have to erase where the dark brown is laying on the light brown underneath it, or will it be ok when the ink goes down?
Say you have a selection and want to add to it by hand:
Go to additive selection mode and when you double click to close the polygon, it adds to your selection.
Likewise with subtractive mode.
Intersect mode is handy too.
You can apply those selection modes to any means of creating selections; wands etc.
You can also save selections and recall them later.
You probably don't need to knock out a light brown under a dark brown.
It's often better not to trap at all if you don't need to. This is why conventional seps are printed light to dark.
Remember to keep that damn anti-aliasing OFF. Likewise feathering. Nothing sucks more than having to recreate a complex selection because you forgot this, or forgot to save it.
not sure I know what you mean by "additive selection mode". I just been using the magic wand and it seems that if I hold down alt and use the arrows to move it in all directions it sort of fills in around the edges, like if I have a blue under a brown...
