Heidelbergs largest Mainstream 80 installation
to date is at Trafford Park Printers in Manchester, England, where commissioning
of two Mainstream 80 presses is well underway.
Trafford Park prints The Daily Telegraph (daily,
1.03 million) and The Sunday Telegraph (Sunday, 805,316), and the first live
production run on the new presses was completed on June 26. The Mainstreams
consist of two folders with six towers each, seven reelstands each and 35
printing couples each. The two presses can be operated independently or as one
press.

Trafford Park Printers is a joint venture company
between The Daily Telegraph, owned by Hollinger, and Guardian Media Group.
The Daily Telegraph prints (approximately) one
million copies per day, of which Trafford Park does normally about 330,000,
seven days per week, including The Sunday Telegraph. The balance is printed by
our sister company, West Ferry Printers in London, said Jacques de Wit,
managing director of Trafford Park Printers.
Trafford Park also prints 130,00 to 150,000
copies, Monday through Saturday, for newspaper titles of Guardian Media Group.
Before the Heidelberg expansion, Trafford Park was using four Goss presses
two to print The Daily Telegraph and two to print the Guardian titles.
The Telegraph decided about two years ago they
needed to re-equip and we bought two Heidelberg presses for Trafford Park and
although we havent signed a contract yet five presses for West Ferry
Printers in London, de Wit said.
Trafford Park has already done several trials and
has successfully run six webs at 77,000 copies per hour on the Mainstreams,
which are designed for print runs of up to 80,000 cph. A supplement for The
Daily Telegraph is now being printed on one of the Mainstreams each week and in
August, Trafford Park began the first night production of The Telegraph on the
new presses.
I [have] migrated production from the Goss
presses onto the Heidelberg presses, a little bit at a time, de Wit said.
The older Goss T-60 double-wide presses were
installed in approximately 1986.
Theyre a good 16 or 17 years old and theyve
worked very hard, because the total output in this plant is something like 8
million copies per week, de Wit said.
With five presses, the Mainstream installation at
West Ferry Printers in London would be a much larger installation than
Manchester. However, that sale is dependent upon performance of the presses in
Manchester.
The two presses at Trafford Park are part of a
seven press order with Heidelberg. That contract (at West Ferry Printers) hasnt
been signed yet, de Wit said.
It is part of our agreement with Heidelberg to
first install the two presses at Trafford Park. We have to accept them here
before the order at West Ferry goes through.
When we placed the order for the presses at
Drupa in 2000 at that stage the only press we had actually seen run of
this model was the one at Drupa. So we were buying, to some extent, something
that wasnt proven. The whole idea is that the two presses in Trafford Park
have to be commissioned, accepted and be in regular daily production before we
proceed with the order for the five presses in London.
The Mainstream 80 displayed at Drupa 2000 was
sold to Danish newspaper printer, Dansk Avistryk.
Trafford Park expects the Mainstream 80s in
Manchester to be accepted and in full daily production by the end of September.
[Heidelbergs] commitment is outstanding. Of
course, they have a lot to prove, he said. This is a big installation for
them. If this one didnt go well it would be bad news for us and, I guess, bad
news for Heidelberg.
Heidelberg relationship grows
Trafford Parks relationship with Heidelberg
has been built since becoming interested in the 4-by-1 Mainstreams at Drupa. De
Wit assembled a team of six printers and one press hall manager that are solely
committed to working on the Mainstreams with Heidelberg employees.
The installation at Trafford Park is part of a
32-million-pound sterling investment (approximately $50 million U.S.). So its
a big investment, de Wit said.
Re-equipping The Daily Telegraph with new presses
was a necessity for Trafford Park because the older Goss presses are limited in
terms of color capacity.
They still have a lot of life left in them,
but have little color availability, de Wit said. Were increasing our
color now by 50 percent with the Heidelberg presses.
Although the new presses have 12 towers, they are
not fully populated, meaning more color can be implemented by adding extra
printing couples.
Theyre relatively easy and its a cheaper
way of increasing color availability rather than the (Goss) T-60 presses,
where
we print with color satellites and we can only print 4-by-1, de Wit
said.
Gapless blankets use air pressure
The sleeve concept of the Mainstream 80 is
unique, Heidelberg officials said. Traditional newspaper printing presses use
rubber, or flat blankets (or sleeves) with two bars on each end. Blankets fit
around the cylinder and there are two bars that fit into a groove in the
cylinder.
The Mainstreams, however, have a sleeve that is
applied on the blanket cylinder with air pressure. Air pressure expands the
sleeve and it can then be slid onto the blanket cylinder. When the air pressure
is taken away, the sleeve fits tightly onto the blanket cylinder. This gapless
blanket concept is designed to eliminate gap-related vibration.
This is quite revolutionary in newspaper
printing, de Wit said.
Although Trafford Park Printers has done numerous
press runs of the supplements to The Daily Telegraph, the blankets need more
tests.
We need to now prove them in long-term
production [and with] long print runs, de Wit said. From our point of
view, of course, they need to have similar, if not better blanket life than the
traditional blanket, because they are more expensive. Its far too early to
say if we are going to get that blanket life, but all the indications are that
it should not be a problem.
The Mainstreams do not have an on-press blanket
washing system, so Trafford Park purchased four off-line blanket washers and one
of the washers has been commissioned.
It is relatively quick, but due to the large
number of blanket sleeves, there is a bit of a logistics problem, which we are
trying to solve by trial and error, de Wit said. We are trying to
establish the best way of handling the blanket sleeves.
Trafford Park has been testing a Techni Web
blanket washer and de Wit said if it is successful it will be retrofit onto the
presses to minimize the need to remove blankets for washing.
Since the washing is not done on the press,
sleeve storage might also have been an issue but not for Trafford Park.
We are fortunate in that our sleeve supplier
has a facility just a few miles from our plant, so they store our sleeves for
us, de Wit said. We have manufactured a storage rack, which we are
currently [testing] to see if it will meet our needs. This is a very large press
and we will have to learn over time what is the best way of handling and storing
these blanket sleeves.
Employees committed to new press
De Wit credits what has so far been a successful
press implementation, to commitment from employees and commitment from
Heidelberg.
At the moment, Im a very happy customer,
he said. Were working well together as a team and thats important when
you have a big project like this. When you have problems which you will
always have at some stage with a big installation its really important
that my people and Heidelbergs people work well together to address those
challenges.
I think all the foundations are in place for
this to be a successful installation and in the next three to six months, well
hopefully prove that.
Heidelberg lands Mainstream 80 sale at Le
Progrés
French regional newspaper Le Progrés, based in
Lyon, France and owned by Holding Delaroche, is investing in two Mainstream 80
presses with a total of 64 printing couples to be installed at its printing
facility in Chassieu, France. A single press is to be installed in
Saint-Etienne.
