Environmentally Friendly 
Cleaning
Environmentally Friendly 
Cleaning 
Using cleaning agents sparingly and minimizing water 
consumption are the first steps towards designing an 
environmentally sound washup program.
Continue 
In either case, the automatic washup systems from 
Heidelberger Druckmaschinen AG help ensure that 
wash procedures are carried out in an 
environmentally friendly manner.
Continue 
In order to significantly reduce air pollutants in the 
pressroom and in the environment, low-emission 
cleaning agents have been on the market since the 
drupa 1990.
Continue 
These cleaning agents are made up of hardly volatile 
hydrocarbon mixtures, vegetable oil esters, or 
mixtures of these. When these products came on the 
market, however, technical problems regarding the 
compatibility of certain materials in the printing 
presses arose.
Continue 
Thus, printing press manufacturers, working with the 
Fogra Graphic Technology Research Association, the 
Berufs genossenschaft Druck und 
Papierverarbeitung, the German Printing and Media 
Industries Federation and IG Media came up with an 
agreement, the "Industry initiative for the reduction 
of solvent emissions in offset printing."
Continue 
Its goals are to minimize solvent emissions in offset 
printing and thus protect people and the 
environment, and to limit the risk of damage to 
machines with a technical clearance test for cleaning 
agents.
Continue 
Fogra's specialized laboratory is commissioned by 
cleaning agents manufacturers. They then test for 
Heidelberger Druckmaschinen AG,
Continue 
 the cleaning agent's physical-chemical parameters 
(including miscibility with water, viscosity, 
temperature behavior, stability and iodine count) 
 the washing agent's compatibility with nonmetallic 
materials (rollers, printing blankets, hose and seal 
materials) as well as
Continue 
 with metallic materials (machine coatings, metallic 
components, printing plates)
Swelling test 
In a swelling test, three identical roller parts are 
immersed in the cleaning agent for 24 hours at room 
temperature. Often the cleaning agent causes the 
rubber material to swell.
Continue 
If this gain surpasses set limit values, it can no longer 
be assumed that a smooth operation is possible. The 
test assembly for a swelling test with roller parts is 
depicted in Illustration 1.
Continue 
Since some types of cleaning agents can corrode the 
coating (Illustration 2), the interaction between 
cleaning agent and the machine coating is also 
tested.
Continue 
Once the individual tests have been completed, 
Heidelberg receives a report from Fogra with the 
results from the clearance test and then decides if 
the product is suitable for use with its machines. If 
successful, the cleaning agent manufacturer receives 
a test certificate from Fogra (Illustration 3).
Continue 
Products which have passed the test are compiled in 
a list which is continuously updated by Fogra. The 
most current version of this list can be found on 
Fogra's homepage. 
Over 290 products from manufacturers all over the 
world have already been successfully certified for use 
in Heidelberg machines.
