摘要： A controller controls printing heads to print a page information mark with black ink to perform line flushing. The printing heads each have a plurality of inkjet nozzles for discharging ink being disposed in parallel in a width direction of web paper. Upon printing the mark, when an overlap region is present in which a mark printable region overlaps a line flushing region with ink other than the black ink, the controller performs control to decrease an ink discharge amount per unit area in the overlap region in the mark printable region to be smaller than that in the mark printable region except for the overlap region and the line flushing region. This causes a decreased total ink discharge amount in the overlap region.

摘要： A printing system is provided with a dummy data insertion unit configured to insert dummy data into print data based on waiting time occurring when post-processing is performed by a post-processing device (for example, a collating machine). In a printing unit, a dummy page is printed on the basis of the dummy data. A dummy page removing unit configured to remove a dummy page from printed printing paper so that the dummy page is not supplied to the post-processing device is provided between the printing device and the post-processing device.

摘要： A printing apparatus of this invention scans with a tester a testing chart printed by a printing controller to acquire testing image data. A total amount of displacement calculator calculates an amount of displacement of a recording position including a direction of misregister as a total amount of displacement, based on a large amount of displacement determined by a large amount of displacement determiner, a direction of displacement detected by a direction of displacement detector, a shift amount corresponding to an amount of displacement detecting chart determined by an amount of displacement detecting chart determiner, and a peak position of the amount of displacement detecting chart determined by the amount of displacement detecting chart determining unit. Thus, since a total amount of displacement of the misregister can be calculated only by printing the testing chart on web paper WP, an amount of displacement of the misregister in the transport direction can be obtained easily in a short time.

摘要： A screening output density corrector of an image processor corrects output densities of a plurality of types of dotted pattern data stored in a screening data storage upon printing. A dotted image data generator uses a plurality of types of the dotted pattern data subjected to the output density correction for performing screening processing to each of images, the images being represented by the continuous tone image data. Consequently, the dotted image data generator generates dotted image data of the images with the corrected output density. Accordingly, output density correction is made not to the continuous tone image data but to the dotted pattern data. Consequently, uniformity of the discharge characteristic (the number of ink droplets) is obtainable upon printing with different types of dotted pattern data. This allows prevention of unevenness in printing through the screening processing based on a plurality of types of dotted pattern data.
摘要翻译：图像处理器的筛选输出密度校正器校正打印时存储在筛选数据存储器中的多种类型的虚线图形数据的输出密度。虚线图像数据发生器使用经受输出浓度校正的多种类型的虚线图形数据，以对每个图像进行筛选处理，所述图像由连续色调图像数据表示。因此，虚线图像数据发生器产生具有校正输出密度的图像的虚线图像数据。因此，输出密度校正不是连续色调图像数据，而是使得虚线图案数据。因此，用不同类型的点状图案数据打印时可以获得放电特性的均匀性（墨滴的数量）。这允许通过基于多种类型的虚线图案数据的筛选处理来防止打印不均匀。

摘要： A printing apparatus includes a head part, an encoder, a tension sensor, a head part temperature sensor, an edge sensor, an estimation part, a storage, and an output part. The estimation part estimates print quality in terms of a page printed by the head part on the basis of variation elements detected by the encoder, the tension sensor, the head part temperature sensor, and the edge sensor. The storage stores print quality information containing the printed page and the print quality estimated by the estimation part in association with each other. The output part outputs the print quality information to a display, a post-processing device, and a printer controller section.
