System and method for improving printing of a leading edge of an image in a gravure printing process |
摘要 |
This invention relates to a system and method for intelligently placing in a periodic and/or random manner a plurality of whetting areas which facilitate lubricating and/or cooling a doctor blade in a printing press when the cylinder is placed therein. The system and method includes one or more routines which analyzes engraving/etching data and any associated white-span length. One or more whetting areas are placed in a periodic or random pattern in response thereto. The whetting areas facilitate lubricating and/or cooling the doctor blade so that it does not heat beyond a predetermined level, thereby avoiding scoring of the cylinder and problems associated with deterioration of print quality or length of cylinder life resulting from thermo-dynamic expansion and/or undesired evaporation of ink associated with areas which make up the image.
