Colour Absorbance Conversion

Hi all, good day,

 

This may seem like an elementary request to some, but i'm stumped and my own research has proved fruitless. 

 

I have been sent the following colour absorbance results:

 

- Absorbance at 420nm wavelength of 0.07

- Absorbance at 453nm wavelength of 0.02.

 

These numbers are to be displayed in our internal quality monitoring as 'R' and 'Y' values. Normally, i'd record it as '2R/9Y' or something of that form, but converting it from these raw absorbance values to these R and Y values is proving somewhat confusing for me. 

 

If anyone can provide guidance, or the calculation needed, it would be greatly appreciated.

 

Thank-you and regards,

 

Gareth
