EXAMPLE:

Complaints such as swelling, softening, polishing etc. were experienced with one specific customer.

 

As all the rollers are manufatured according to ISO 9001:2000 Quality Assurance System, we were sure that all the rollers manufactured would have the same quality. Therefore we investigated the ink and wash solvents applied on rollers by this specific customer.

 

The results showed that the swelling was due tot he roller wash solvents used. For instance brand A solvent caused 0.5% swelling effect where as brand B solvent caused 40% swelling effect. The rollers washed with brand B solvent were found to have premature wearing and various performance problems.
