What is (ITR) technology, and how can it benefit my company?
|
|
“ITR”, otherwise known as “In the round” is the generic term
that has been used for a long time to describe any image that has been produced
around the circumference of a plate cylinder or sleeve in either a photopolymer
or elastomer covering. The technology has been used primarily in Europe for more than thirty years with elastomer coatings being vulcanized, ground and directly
laser engraved onto sleeves and integral rolls. While plate material has and
still can be exposed in the round and is classified by some as “ITR” , I
personally only classify it as true “ITR” if the material has been bonded or
vulcanized to the sleeve or roll circumference and engraved or washed out while in a continuous format. As to the benefits of true “ITR”
there are many ranging from dramatically increased press speeds, improved print quality, improved
registration, more uniform densities, less dot gain, less bounce, reduced
waste, improved productivity, improved profitability, less set up time and less
make ready.

We hear so much about best practice being necessary for good quality print but how do we define what is best practice?
|
|
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.
