Laboratory equipment and analysis possibilities

1. Modern laboratory for solid body analyses:

• Scanning electron microscope (SEM) examinations
  for surfaces of printing press components (e.g. bearer rings, elastomer covered rollers, roller bearings, cylinder coatings etc.) for the exact technical evaluation of cases of damage, such as:
   
  • Corrosion
    As an example we refer to the article “An expert reports from his experience” in the journal “Deutscher Drucker”:
    Issue 60, DD No. 40/03-12-2009
  • Mechanical wear
    As an example we refer to the article “An expert reports from his experience” in the journal “Deutscher Drucker”:
    Issue 20, DD No. 42/20-12-2007
  • Tribological effects
  • Fatigue failures
  • Overload breakages
  • Electrochemical attacks
  • Mechanical overloads
  • Damage in the paper
    As an example we refer to the article “An expert reports from his experience” in the journal “Deutscher Drucker”:
    Issue 18, DD No. 38/22-11-2007
     
• lectron-probe x-ray microanalysis (EPXMA) examinations for the determination of the chemical composition of solid materials for the exact technical evaluation in cases of damage or to avoid damage, respectively, for instance:
   
  • Determination of corrosion residues
  • Preventive oil analyes for cylinder bearings
    As an example we refer to the article “An expert reports from his experience” in the journal “Deutscher Drucker”:
    Issue 30, DD No. 20/05-06-2008
  • Evaluation of material qualities
     
• Internal stress measurements at impression cylinders, rollers, ink and fountain rollers in order to detemine the deformation of these components in the printing press:
   
  • Impression cylinders of sheet-fed presses
    As an example we refer to the article “An expert reports from his experience” in the journal “Deutscher Drucker”:
    Issue 33, DD No. 26/07-08-2008
  • Inadmissible deformation of ink and fountain rollers
     
• Metallographic examinations of all kinds for fast and reliable analyses of cases of damage or preventive quality controls (side frames, impression cylinders, ink and fountain rollers, rollers, roller bearings, components of the folder, etc.):
  • Strength measurements (tensile tests, hardness measurements, fatigue resistance measurements, notched bar impact strength measurements)
  • Taking samples of printing press components
  • Preparing metallographic sections
  • Structure examinations of metallographic sections

2. Modern laboratory for analyses of consumables:

• Evaluation and expert certification of fountain solution additives for newspaper, commercial and sheet-fed printing presses.
  As an example we refer to the article “An expert reports from his experience” in the journal “Deutscher Drucker”:
  Issue 15, DD No. 32/11-10-2007
   
• Evaluation and expert certification of printing varnishes of all kinds
  As an example we refer to the article “An expert reports from his experience” in the journal “Deutscher Drucker”:
  Issue 09, DD No. 20/21-06-2007
   
• Evaluation and expert certification of silicones
   
• Evaluation and expert certifications of anticorrosive oils
  As an example we refer to the article “An expert reports from his experience” in the journal “Deutscher Drucker”:
  Issue 17, DD No. 36/08-11-2007
   
• Evaluation and recommendation of suitable process water for printing presses
  As an example we refer to the article “An expert reports from his experience” in the journal “Deutscher Drucker”:
  Issue 11, DD No. 24/09-08-2007

3. Analysis of problems and failures related to printing process engineering:

• Ghost effects in commercial printing
  As an example we refer to the article “An expert reports from his experience” in the journal “Deutscher Drucker”:
  Issue 24, DD No. 08/28-02-2008
   
• Blistering in commercial rotary web offset printing
  As an example we refer to the article “An expert reports from his experience” in the journal “Deutscher Drucker”:
  Issue 18, DD No. 38/22-11-2007
   
• Corrugation in commercial rotary web offset printing
  As an example we refer to the article “An expert reports from his experience” in the journal “Deutscher Drucker”:
  Issue 21, DD No. 02/17-01-2008
   
• Printing quality, doubling, ghosting, dot gain, etc.
