Yes. Someone has another color sep question.
This is what I have CS2 and a jpeg. picture with 2 colors (lets say Red/Blue) in the pic/design. I need to print a Red layer and a Blue layer. in order to burn my screens. How do I do it? Do I just need to adjust something on the print preview screen or do I need to change the colors via magic wand or what? What is the simplest most efficient way to get the layers from the printer.

CS2, but Illustrator or Photoshop?
You're going to have to separate the colors into layers, make them pure black, darkest black, and print each layer on it's own film, with cross hairs for registration.
Photoshop CS2.
Yeah I know they need to be separated into layers. And I know they need to be black. Can the colors be separated by the program or do I need to manually do it. What is the esiest way to get them into layers.

start with an image size of 300 pixels if you can...
select> color range>(pick the color,adjust the slider, check "selected areas only" in the box) >ok.....now your color is selected in all its areas ,then in the tab called "channels" next to the "layers" tab click the lttle black arrow in the right corner, the dialog box opens and select "new channel" a box will appear with the title "alpha 1" rename it blue or whatever, click the color dropper to the color,and make sure that "selected areas only" is checked, then hit ok.....now the page should be white with the "selection" highlighted (if its not go back and make sure selected colors only is enabled).......now select from the drop down menu on top >and hit "inverse" or ctl+shift+i for the short cut....now "deselect" or control+d for the shortcut....now you have an "alpha channel"continue for each other color and can print right from here and also preview the seps and how they print by turning off the RGB channels and turning on the alpha channels,
I like to make a layer of reggie marks and make an alpha channel with them and then hit image(from the drop down) >apply image > and then drop down the channels and click the alpha channel for my reggies and "apply" them to each colr alpha channel.....complete set of seps in register with reggies and when you get good you can build an awesome white backer with chokes and spreads( by using edit >stroke to your selection)........this is where simulated process seps are created in fast films and similar programs...
then finally for simple spot colors , go to image>flatten > then go to channels >split channels and then on your sep channel image>mode> bitmap>300ppi>diffusion dither>print.... this converts the sep to a 1bit bitmap and it will be a small file and rip to the printer FAST.....it takes alot of typing but it really goes fast when you learn it ,
I just do it manually. It's easy if the colors are flat.
Select the magic wand and make sure the contiguous box is checked off. Click on the first color. This will select all of it. Do New layer via cut. The first color should now be its own layer. Label that layer the color that it is, so you can keep track. Then use the magic wand to again select all of the first color, then do ctrl+f5 (or might be shift+f5) and you can replace all of the first color with pure black. Repeat for additional colors.
Hope this helps. That's how I do it. You can change the exactness of the color so that you would get the solid red of a design and everything a few shades off. I forget what that setting is called.
I use the color range picker and save the selections as channels. Then I make the channels spot colors. Gives a more accurate preview of the stacking of the colors and the output is automatically 100% black.
Muck more control and accuracy using channels.
Again with the color separations?
