摘要： Methods and systems herein provide for calibration of a production printing system that accommodates a plurality of different print paper types, including new paper types with no ICC profiles or optical density curves on file. One exemplary method includes printing test patches of primary colors on a first print medium, measuring colors of the test patches printed on the first print medium to determine an optical density of the first print medium, and comparing the optical density of the first print medium to a plurality of optical density curves to identify a comparable optical density curve of a different print medium. The comparable optical density curve is one of a plurality of optical density curves installed on the production printing system. The method further includes automatically selecting the comparable optical density curve to calibrate the production printing system to the different print medium for use in printing to the first print medium.

摘要： A test target is written in a non image zone at set time intervals. The test target is sensed. At least one of frequency, amplitude and phase of banding, which is inherent in a printing device, is determined based on the sensed test target. At least one banding compensation parameter based at least on one of the determined frequency, amplitude and phase of banding is determined. Characteristics of producing an image based on the determined banding compensation parameter are adjusted to compensate the banding inherent in the printing device.

摘要： An image-forming system determines a type of paper for each single sheet in a job to determine whether it is prohibited to discharge a sheet to a finisher (step S12) to respond to diversifying demands to perform processes after printing using a plurality of paper types. However, the system allows paper to be included in a sheet bundle if the number of sheets is below a fixed limited number of sheets, even if paper types used are inappropriate for the finisher to be the discharge destination. (Steps S14, and Spaces 16) Therefore, discharge to the finisher is not rejected uniformly by the type of paper; finishing can be implemented after printing with a certain degree flexibility.
