This is a
very big subject but for me best practice is about eliminating as many
variables as possible on and around the press. You need to look at each aspect
of the print process and determine what you believe to be the most effective in
helping you to achieve consistent results.
This usually starts by measuring and
recording what is being done to help to determine if it is repeatable and if
the results are acceptable. Generally the use of measuring devices such as
spectrophotometers, densitometers, video web inspection, interferometers,
viscometers are necessary to help capture the necessary data in an accurate
form that can then be repeated and measured accurately each time a job is run.
Always try to get your suppliers involved at the earliest stage possible as
they will then be able to assist you in achieving what is best practice for you
and your company and more to the point, how to define it.
