1. A method of evaluating data capturing in a forms processing system comprising steps of incorporating simulated forms data as images of predetermined contents into a workflow of a data capture system; the simulated forms data being computer generated from the predetermined contents, associating the predetermined contents in a machine-readable form with the images of the forms data, interpreting the images of the forms data within the workflow of the data capture system for inferring contents of the images, comparing the inferred contents to the predetermined contents, and scoring results of the comparison for evaluating the data capture system, wherein forms data subject to interpreting provide statistically significant results.
