Learning Event 1:
NEED FOR QUALITY CONTROL
1. Quality control is as old as industry. From the time man began to
manufacture, there has been an interest in output. As far back as the
Middle Ages, guild members (now union members) were required to serve long
apprenticeships. Only after long periods of training and demonstration of
skills and techniques were they considered craftsmen. Even today, man
strives to improve the quality of the end product and uses various controls.
Standards have been set to assure quality; however, the standards that are
set are only as good as those that are kept. Low standards equal low
quality; high standards equal high quality. Inspections and tests are
conducted to maintain and assure quality products.
a. Camera or laboratory technicians also are concerned about quality
and aspects of its control. Quality control has one purpose; to assure
repeatable quality of the end product, whether it is a negative,
transparency, or some other product. Quality control can be applied to the
entire system or any portion of it.
