The site has opted for a Technotrans Alpha.c combination unit to control both the inking and dampening temperature and an Alpha.f filtration unit for its latest press, a Komori L628.
A statement from Technotrans said that consistent temperature and ink tack as well as consistent dampening allow the company to remove variables from production, preventing scumming, which is a hazard with UV inks.
Meanwhile filtration, the removal of debris from the dampening, is a prerequisite to reducing alcohol levels.
Print manager Terry Plumley said: “We were cleaning out the dampening every two or three weeks before we invested in the Alpha.f. Now it will be every three months.
“The reduction in the cost of chemistry is probably offset by the investment in filters but where we definitely cut costs and effort is in the reduction in maintenance time.”
The filtration unit uses a bypass connection to the dampening solution tank of the circulator. The dampening solution goes through a double filter system resulting in perfectly decontaminated dampening solution and a clean system. This cuts down on waste disposal costs and maintains equipment at its optimum level.
Alan Footitt, print and cut and crease production manager, said: “We now have full consistency across all four presses, two B1 and two B2, so when the water pH and conductivity is tested we know exactly what it should be.”
