Does this sound familiar?
At one time your press was brand new and
printed with the consistent performance and dot value of a
new press . . . over the years you observed problems with
inconsistent dot value and experienced increased adjustments
to achieve consistent dot value.
How does this happen?
Over time a roller becomes hard, pitted
and worn creating hickeys. Eventually the durometer is too
high, causing the rubber to shrink unevenly. Consequently,
glazing occurs, as a result of excessive leaching of extractable
oils. The result is a roller that is about 40 durometer and
that will require 10X the amount of mechanical pressure as
a 26 durometer to achieve the same stripe setting. With additional
MECHANICAL PRESSURE - you get additional UNWANTED heat. Additional
ENERGY creates additional HEAT - the law of science.
Consider this . . .
The roller train can only be as good as
its weakest link. Consistency in rollers from unit to unit
will deliver consistent water and ink balance, as well as,
consistent dot value from unit to unit. Unfortunately, the
accepted practice when time to change rollers has been to
use “exchange” or used cores. Used cores lack
concentricity to the detriment of press performance. Regrettably,
the objective of replacing rollers in the press has never
been to maintain consistency throughout the ink train. Therefore,
the range of effectiveness of the individual printing units
can go from excellent to very poor. When starting out with
all new rollers in each of the units - meaning new core, cover
and bearings - you have TOTAL CONCENTRICITY.
Why is consistency in rollers from unit to unit important?
The function of a roller is to transfer
and split ink, as well as to work in cooperation with the
vibrating roller to fold-blend ink and water together as to
maintain water and ink balance. Therefore, the performance
of the actual press is in the ink train: Water and ink balance.
How do you obtain and maintain water and ink balance?
Consistent pressure and new rubber...
When you buy a new printing press then look at the press performance
3 to 4 years later, the only thing that has changed is the
performance of the rollers and blankets. Rollers and blankets
in poor condition lack the ability to provide optimum performance
and this significantly affects print quality. The press still
picks up and delivers sheets the same. The main difference
is the - HEART OF THE PRESS - the printing unit: the INK TRAIN.
What can be done to establish consistency from inking unit to inking unit?
Pacesetter presents: A BETTER WAY TO DRESS
YOUR PRESS A plan to RESTORE consistent press performance
- Consistent dot value.
- Less downtime.
- Reduced make-ready time.
A program to install NEW ROLLERS in each of the inking units
at one time:
- Brand new steel core and rubber covering guaranteed for
- A quality product supported by the manufacturers guarantee.
- Developed exclusively for the printing industry.
- Factory trained Technical Specialist to oversee installation
- The largest inventory of finished rollers in the UK to guarantee
on time delivery
What could one year of TROUBLE-FREE printing do for you?
With Pacesetter's "A Better Way to
Dress Your Press" Program YOUR DOWNTIME WILL DIMINISH
AND SAVE YOU THOUSANDS OF POUNDS WITHIN THE NEXT FISCAL YEAR.
In a year you could spend £20,000
- £25,000 in down time. When we put all new cores, cover
and bearings in ever unit of the press we are taking it back
to the day you bought it. With the traditional method of changing
rollers - one here - a few there - the downtime adds up. After
a couple hours of downtime: for each change.
By changing all inking units at once the press is RESTORED to:
Consistent print quality in ALL the inking units
Consistent mechanical pressure
Same heat or temperature
Consistent water and ink balance
Doesn't it make sense to install Brand New CONCENTRIC Rollers in each Inking Unit IT'S LIKE BUYING A NEW PRESS, YEAR AFTER YEAR.
