The exchange of reflectance data among retail and branded apparel companies with their suppliers
has increased substantially over the past five years. These electronic color programs are creating a
"flatter color space" by connecting tiers of suppliers across continents via a common color language and
protocol. The instrument, or spectrophotometer, in most cases provides the baseline upon which all
other factors are built. In this paper we will discuss the process of spectrophotometer correlation - or
profiling - whereby a spectrophotometer is characterized parametrically and corrected to measure like a
standard instrument using software and a series of reflectance standards.
