Recovery Remeasure the samples using the same specular port setting If you want to apply gloss compensation choose the Gloss measurement condition and repeat the sample measurements Strength Option Purpose In the manufacture of a colored product it is important to develop a formula that will reproduce the color accurately and efficiently each time A production formula is reliable only if the raw materials used in the formula are consistent from lot to lot A strength evaluation is based on the ability of the colorant to absorb light and determines if the current batch of colorant is stronger or weaker than the material used in the original formula The evaluation also projects the color difference between the two lots of colorant when they are at equal strength This information helps you to determine if the concentration of colorant s in a formula needs to be adjusted to reflect differences in the raw materials 156 Other Options Datacolor CHECK II Sample Preparation The strength of a colorant is defined only in reference to another colorant that has identical colorimetric and physical properties In order for the strength evaluation to be meaningful you must prepare your samples in a uniform fashion keeping in mind the following points The samples are usually finished samples of your product such as a dyed fabric or a coating applied to a substrate Colorant strength should only be evaluated using
