Abstract

Using the molding tool (2), spatially-resolved spectrometer (1) and computerized device (101) of U.S. patent application Ser. No. 09/303,409, streaking problems identified in production are first diagnosed (140), then duplicated on a laboratory scale (142) and compared with the streaking problems observed in production. Next, options are developed and tested for fixing (correcting) the observed problem and testing these on a laboratory scale (144). Finally, the option(s) chosen for correcting the observed problem are validated prior to reinitiating full-scale production (146).
