Appendix

Gives information and data that can be collected during the generation and use of phototools to improve artwork quality and thereby improve yields downstream. It may also be used to help establish and maintain ISO 9000 certification and SPC, to facilitate troubleshooting, and to standardize the process. Also helps to identify process improvements for ultimate elimination of inspection and touchup of artwork.
