Measurement Backing

11x17" double side black and white measurement backing

ChromaChecker™ measurement backing offers proper condition for capturing spectral measurements.

 

White Backing side

According to ISO:13655, white backing should have diffuse-reflecting surface.

Typical ChromaChecker QC batch production measurement:

  1. Opacity 100% (99,3% single page) [expected value >99%}]
  2. FLuorescence = 0,0 [expected 0,0]
  3. L*= 94,6  [requirement: L* shall not exceed 97], a*=-0,94    b*= 1,34 
  4. C*=1,64  [requirement - shall not be larger then 3.00], h*=125,1 
  5. Reflectance for given wavelength shall bein given by ISO13655 range (380-730nm:

    0,1190 0,2258 0,4528
    0,6727 0,7738 0,8069 0,8224 0,8345 0,8453 0,8530 0,8582 0,8613 0,8619
    0,8611 0,8603 0,8570 0,8538 0,8499 0,8444 0,8461 0,8470 0,8474 0,8467
    0,8472 0,8469 0,8481 0,8515 0,8555 0,8584 0,8627 0,8668 0,8688 0,8733
    0,8765 0,8767

 



Black Backing side

According to ISO:5-4 black banking should have diffuse-reflecting surface.

Typical ChromaChecker QC batch production measurement:

  1. Average Density = 1,44 [have to be between 1.30 – 1.70]
  2. Density Range = 3,9% [expected value shall be less than 5%]

 

 

Cleaning / Chemical resistance

In order to wash the surface, a small amount of the following substances applied on a soft cloth can be used (do not immerse in the bath):

  • water (recommended osmotic or distilled water)
  • water with a small amount of washing up liquid (recommended osmotic or distilled water),
    Caution: rinse at the end with osmotic or distilled water
  • isopropyl alcohol i.p.a 

 

The product is definitely not resistant to such substances as:

  • Acetone
  • Acetonitrile
  • Ammonia
  • Benzyl Alkohol
  • Chlorobenzene
  • Cyclohexane
  • Diethyl Ether
  • Ethyl Benzene
  • Isopropylbenzene
  • Nitrobenzene
  • Nitrotoluene
  • Styrene
  • Toluene
  • Vinyl Acetate
    and more
