PANTONE¨ Color Picker for the AppleVisionª Color Display
                                     
                                    
The PANTONE Color Picker consists of a self contained Macintoshª system extension.  This extension is an extensible color picker module which displays calibrated PANTONE Colors from the PANTONE¨ MATCHING SYSTEM.  It will display the PANTONE Colors in three modes:
  
  PANTONE MATCHING SYSTEM - As printed as a spot ink on a coated paper stock
  PANTONE MATCHING SYSTEM - As printed as a spot ink on uncoated paper stock
  PANTONE MATCHING SYSTEM - As reproduced in four-color process ("Spot to
  Process")
  
System requirements are:
  ColorSync¨ 2.0
  Apple Color Picker Extension
  ICC/ColorSync 2.0 Monitor profiles
  
  
Installation
  Assuming you have ColorSync 2.0 and the Apple Color Picker 
  extensions installed on your Macintosh, copy the PANTONE Color 
  Picker extension into the Extensions folder within your System 
  Folder. Then copy the ColorSync/ICC source profile into your 
  ColorSync Profiles folder inside the Preferences folder. The source 
  profile is named Pantone XYZ Source Profile and ensures that the 
  purest PANTONE Color information is processed by ColorSync and your 
  new AppleVision monitor.
  
  Restart your Macintosh prior to using the Color Picker.
  
  
How to load the PANTONE Color Picker
  You can use the PANTONE Color Picker anytime the built-in Macintosh 
  Color Picker is called by software running on your Macintosh. When 
  the Color Picker is called, a dialog box such as the one shown 
  below will appear.
  
  When you exit the dialog box by clicking the OK button, the color 
  value you selected is returned to the calling application or 
  utility.

Setting the Display Profile
  You will need to tell the PANTONE Color Picker what monitor profile 
  you want to use. Select your monitor type in the pop-up list under 
  Profile:  You new AppleVision Color display ships with software 
  which enables you to re calibrate you monitor at any time and 
  create a current ColorSync profile. If you use this software, make 
  sure you save the profile in the ColorSync Profiles folder prior to 
  loading the Color Picker.
  
  
Selecting a PANTONE Color Mode
  The PANTONE MATCHING SYSTEM is provided in three different flavors. 
  You can obtain display simulations of PANTONE Colors as they would 
  appear printed on Coated Paper, Uncoated Paper and as printed in 
  four-color process on Coated stock. You will notice that the 
  appearance of the colors change when you select each of the three 
  modes.
  
  
Selecting a PANTONE Color
  To choose a PANTONE Color you can type the number in the edit field 
  below the horizontal scroll bar. Or you can simply scroll through 
  the colors until you find one you like. Additionally, you can click 
  on the vertical multi-colored bar on the right side of the PANTONE 
  Color display to jump to a particular color range.
  
Computer Displays _ Additive Color Mixing
  Additive color mixing is the basis for non-reflective 
  sources such as computer monitors and televisions.  
  Non-reflective sources are actually light sources, and each 
  pixel on a color computer display is a separate light 
  source.
  
  Each pixel on a computer display is composed of three 
  "cells," each of which is coated with a different type of 
  phosphor.  One type of phosphor emits bluish light when it is 
  bombarded with electrons, one emits greenish light, and the 
  third emits reddish light.  In theory (though not quite in 
  practice), each of these phospors operate independently of 
  the others.  The intensity of the light  emitted by each 
  phosphor more or less depends on the intensity of the 
  electron beam bombarding it.  The color of the pixel results 
  by adding together the light emitted by each of these 
  phosphors.
  
  The relationship between the intensity of the beam and the 
  light emitted by the phosphor is only approximate and 
  indirect.  This can cause real problems for those who wish 
  to display accurate and repeatable colors.  
  
  A factor that can effect color accuracy on a monitor is 
  called "gamma".  Gamma occurs because the intensity of light 
  emitted by the pixel phospors is not directly proportional 
  to the number of electrons hitting them.  Actually, the 
  brightness emitted varies with a number that is between the 
  square of the number of electrons and the cube of that 
  number.  For example, the monitor has a gamma of 2.6.  This 
  means that the brightness of the light emitted by a phosphor 
  on that monitor is proportional to the number of electrons 
  hitting it raised to the 2.6 power.
  
  In order to ensure consistent color reproduction, all video 
  cards for Macintosh displays have "average gamma correction" 
  tables stored on-board the card.  If the monitor response is 
  measured and recorded in such a table, the monitor will be 
  able to consistently reproduce colors.
  
  
Color Gamuts
  Each set of color primaries (RGB, CMY) define a "color 
  space" that includes all colors that can result from any 
  combination of these primaries.  The "color space," or 
  "color gamut," may be quite different for different sets of 
  primaries.  Typically, a CMY color gamut falls inside (is 
  smaller) a RGB color gamut, which means that the eye can 
  detect (or a monitor can display) more colors than a printer 
  can print.  In other words, it is not possible to print some 
  colors that can be photographed or displayed on a montior 
  when using CMYK printing.
  
  Some of the PANTONE Colors do not fall within the RGB color 
  gamut for particular monitors because the primaries (or 
  phosphors sets) are much more saturated than those that 
  define the RGB gamut for particular phosphor sets.  RGB 
  color gamuts vary as well.  For example, the color gamut for 
  one monitor may be quite different from the color gamut for 
  another, since the phosphor set that produces the RGB 
  primaries, the gamma correction and other variables for the 
  monitors may be different.
