An ideal tool for print quality assurance, the web inspection machine with advanced defect detection system enables us to get rid of the poor quality printing material. This machine can also be adapted for the removal of edge trims, taking the load off the slitters. Inspection machines are used to inspect materials in order to find manufacturing defects, mechanical defects and dirty spots. Inspection machines have an illuminated panel, under the material. This machine rewinds and measures material in order to verify length of roll declared by the manufacturer and precisely mark distances between defects on the inspected roll of material. Yet another very important feature of the inspection machine is to ensure even tension of rewinded material. This is a very important condition for spreading and cutting operations in future. Material inspection machines are used by manufacturers, where high quality of manufactured products requires additional quality check before materials are sent for spreading and cutting.
