Hi all,
I'm hoping someone can help me out here with the following. I have a photoshop file that I have to save as seperate color channels.
How do I do this?
Thanks in advance

How many colours is it?
Do you need to create only one file or can you create a separate one for each colour?
- PunchDouble0
2 colors (white and gold) and a background color (black)
it needs to be printed as a sticker so I assume I have to create one file only?

There's a few ways of doing this. Can you post up a visual?
First thing though... is this litho print? If so, the substrate will be white and you'll need to print the black... the fact that you're talking about printing white onto black suggests you're screen printing though, unless its the old designer's favourite of white litho ink onto Plyke board...?

Okay, so make a copy of the photoshop file.
1. Make the base white.
2. Combine all the nonblack areas (the white AND the gold) onto one layer, Make it all black. Call it: white base print.
3. Have just the gold areas on another layer, again in black. Call it:gold overprint.
If you just name the layers that and talk the printer through it plus show them the visual... not a problem. The difficulties arise if you try to combine the visual end result with the artwork. All artwork is always on a white base and all print is presented as black, or tints of black. You're probably scratching your head about starting off with a black base board layer. You can make a duplicate of the above file to give to the printer as well where you colour the base layer, the white and the gold layer so they are visually correct... he can refer to that for visual purposes.
That's my two penneth.

By the way...
"I'm working on a new site, this'll have to do for now :-)"
... Can I borrow that for my site?

Hmmm, I was thinking you were trying to split an image or something similar. This is a bit out of my photoshop realm. For an image like that I would use Illustrator or Indesign where colour seps are much easier due to being vector based.
Hopefully spooky can help you, sorry Im not much help on this

okay first off thanks
second to check if i understand correctly
ill make a file w/ 2 layers?
one thats the white and gold called white base print
one thats the gold called gold overprintand i make both layers black?
- PunchDouble0
hahahaha ofcourse you can borrow it
its been there forever ;)oh and weave.. is it much easier in illustrator?
cause if so i might as well recreate it in illustrator

Also for screen printing you'll need to bleed about .25mm around the edges of the gold for registration purposes. If you do the gold flush to the white you'll get white edging. You want to protect the knock outs in the middle of the B-Boy stamp (the lettering and the highlight cresents) but then extend the rest of the gold edges really slightly so it overlaps a tiny amount beyond the 'white layer' information. Not too much though becuase gold is opaque so will really show up on the finished job.

... about a million times easier in Illustrator. And also, make three layers: a blank white base layer, then a white base print layer, and then a gold overprint layer. Its also easier to print the black and gold onto a white base but I'm guessing its vinyl you're talking about here.

okay
if you dont mind
how do i do it in illustrator? the easier the better

The way spooky explained it is pretty good and seems easier than redoing it. What you are saying you will do is how I understood spooky's instructions as well.
The benefit of illustrator is that it's vector based you can assign the colour to an individual object/text. So you don't need to do the layers as you do in photoshop and you can leave it in those colours rather than changing it to black.
Printers will probably be happier with illustrator/vector files to.

Haha I'm just to slow here,
Illustrator:
Create artwork all in vectors.
Create two spot colours - white and gold
Apply a spot colour to each object as applicable
- PunchDouble0
well i have it redone in illustrator already
wasnt that much of a hassle
but ive experienced this too "Printers will probably be happier with illustrator/vector files to."
hence my question how to do it in illustrator :)
- duckofrubber0
Vector > Bitmap
- PunchDouble0
so what do i save it as in illustrator?
eps?
meaning how will the printer have the seperate color channels?
im slow too lol
