  Some important things you should keep in mind:

- This media does contain the IT 8.7/2 reference file for the
  calibration target charge "R080505". Select the file "R080505.txt"
  as reference file when using the profiling software.

- Handle the targets carefully to avoid kink marks and scratches.

- Remove the protection sleeve of the photo before use.
  Return the test target to it's protective enclosure immediately
  after use.

- Always protect the calibration photo from strong light.
  Store in a cool dry and dark place, preferable 70 F (21 C)
  and not exceeding 50% RH. Avoid sudden temperature changes
  as this can cause moisture on the photo surface.
  Use a dry lint free cloth to dry/clean the surface.
  DO NOT USE ALCOHOL or other chemicals to clean the surface
  of the photo.

- The colors of the target will change with time. For critical work
  it is recommended to get a new target every 1-2 years if you want
  to avoid any quality loss. 2-3 years are fine for normal use.
  Please check out http://www.targets.coloraid.de for the latest
  information on your charge.

- You  can  use  the calibration photo with basicly any other
  proper  IT  8.7/2  software on PC/Mac/Amiga/Sun and other systems.
  Note that the reference file is identical for all systems and
  thus can simply be transfered to other systems in order to get used.

- The "Extras" directory does contain additional files for your
  target:

  R080505.eps and R080505.hist provide the spectral data of the target.
  The files can be used with the X-Rite ColorShop V2.x and
  ColorShop X software. A full functional but time limited demo version
  of the software can be downloaded from the X-Rite site at
  http://www.x-rite.com. Note that the ColorShop file only contains
  the spectral data from 390-700nm or 400-700nm while the normal
  reference file is based on 380-780nm data. Tests done show that
  this limited precission by ColorShop causes only minor faults.  

  The "Extras" directory contains files for illuminants other
  than D50. It also contains data for the CIE 1964
  10 degree observer.  Color data for even more illuminants or
  observers can be calculated using the spectral data
  (ColorShop can easily do this for you).
  
  Following illuminants/observer files are available in "Extras":

  R080505A.txt     - Illuminant A, 2 Degree Observer,
                     Illuminant A was intended to represent the

                     lighting and in projectors.
