Kodak supplies Control Strips for monitoring processing of all Kodak Sensitized Goods (film & paper). They are precisely exposed strips of paper or film that contain varying density and color patches for monitoring sensitometric response to chemical and mechanical conditions of processing equipment. Correction Factors are given in the instructions packaged with each box of Control Strips. Add these correction factors to the reference strip densities to determine aim values. Correction factors differ for each code number.
Through the years, Kodak has led the way with an abundance of new products and processes that have made photography simpler, more useful and more enjoyable. Today, the company's work increasingly involves digital technology, combining the power and convenience of electronics with the quality of traditional photography to produce systems that bring levels of utility and fun to the taking, making and utilization of images.
