69.0. "Spot color separations" by TNPUBS::JONG (Steve) Fri May 01 1992 13:49

    Question:

    	I would like to create an Interleaf document with spot color, and
    	print the document with color separations.  How do I do it?

    Answer:

       If you have the Advanced Graphics package, or Full TPS (which we
       all do), it is possible to assign a color attribute to text,
       bit-mapped images, or drawn objects, and to print a document with or
       without those elements.  When you print a separation, you will get
       two copies of every page with a second color: one with only the
       first-color elements, and another with only the second-color
       elements.
       
       The Interleaf documentation (_Diagramming_, pp. 158-162; 
       _Interleaf Basics_, pp. 80-82) is enigmatic on this point. 
       Attend:

       1)In an open Interleaf document, from the document name box (which
         shows the name of your document) pull down  Misc->Palette->Colors. 
         The color palette window opens.  

         The color palette window contains eight boxes representing the
         various black-and-white screens available (0%, 3%, 6$, 13%, 25%, 
         50%, 75%, and 100%).  Note that these default screens are shades
         of gray; no colors are defined in a default document.  You are
         defining a color.

       2)Click on a box; the border is highlighted.  I recommend clicking
         on the 100% (black) box.
       
         Select Copy; the clipboard flashes and the highlighting goes away.  
         Select Paste; a copy of the box appears below the first eight.

       3)Click on the new box and select Props; the Color Editor window
         appears, with color bars for cyan, magenta, and yellow.  

           Click anywhere in any bar and select Move (the default); drag
           the vertical indicator down below 50%.  (If you don't drag it
           down below 50%, it won't work.)  The pattern in the sample box 
           in the Color Editor window changes to indicate that you have 
           created a new color.  

           When you have modified the color to your satisfaction, select
           Apply and the Close in the Color Editor window, and then Apply
           and then Close again in the color palette window.  The new color
           is now available for use.

       Now you can create spot color separations.  

         For example, to mark  a line of user input for red printing,
         select a range of text, and  from the text properties box (which
         normally says <Default Text Props>) pull down the Color property. 
         In addition to the regular shades, you will see the shade you have
         just created; select it, and the text property becomes Color.  

         To fill a drawn object with color, open the frame containing the
         object and select the object.  Select Props->Fill->Color and the
         new shade you have created; the status line shows the color
         percentages of the shade you created. 

         To edge a drawn object in color, select Props->Edge->Color and the 
         new shade.

       If you print this document as is, the colored areas will print
       out as a shade of gray.
       
       To print a separation (two copies of every page with second color):

       1)From the printer box pull down Properties; the Printer Property 
         sheet appears.

       2)Change the Spot Color Separation property (the last one on the list) 
         to Solid, select Apply, and select Close.

       3)Print the document; you will get color separations, with
       second-color areas printed in black.
