Title:
METHOD FOR CONTROLLING PRINTING PROCESS
Document Type and Number:
Japanese Patent JP2873266
Kind Code:
B2
Abstract:

PURPOSE: To best approach to a predetermined target curve by calculating many actual value characteristic curves capable of theoretically performing at a parameter change from an actual value characteristic curve obtained during printing, and selecting the curve most coincident with the predetermined curve according to a quality reference from the many curves.
CONSTITUTION: Many actual value characteristic curves capable of performing based on a measured value of a sheet by a color density measuring unit 2 are calculated by a characteristic curve generator 3. A corresponding parameter can be output from a memory 4. Further, a target value characteristic curve to obtain during printing is preset with a target presetting unit 5. A comparator 6 selects one from calculated performed actual value characteristic curve group according to a predetermined quality reference. A controller 7 obtains a necessary regulation command based on the actual value curve and outputs it to a controller 8 of the printer 9.
