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密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 displacement amount calculation part in a base material processing apparatus calculates the degree of matching between an upstream data section and a downstream data section included in a first and a second detection results, which indicate time-varying changes in the positions of an edge of a base material in the width direction at an upstream and a downstream detection positions. This calculation uses calculation results obtained by sequentially calculating the degrees of matching between sub-data sections in the upstream data section and downstream sub-data sections in the downstream data section. This reduces the amount of computation and enables highly accurate detection of the amount of displacement of the base material in the transport direction on the basis of an identification result of the downstream data section that is highly matched with the upstream data section.

摘要： Disclosed is a printing apparatus that performs printing onto a print medium including a transporting device that transports a print medium, a plurality of printing heads, a photographing unit that photographs the print medium, a shift detecting chart forming device, and a correcting device. The shift detecting chart forming device forms a shift detecting chart having a first line segment group consisting of first line segments that are printed onto the print medium at given intervals in an orthogonal direction with respect to the transportation direction with a reference printing head, and a second line segment group formed along the first line segment group, and consisting of second line segments that are printed with a subsequent printing head. The correcting device corrects a printing timing with the subsequent printing head relative to the reference printing head in accordance with a density variation of the photographed shift detecting chart.

摘要： An image shifter creates plural pairs of shift image data. A shading corrector and a halftone dot processor create halftone shift image data from shift images. Further, a difference image creator creates halftone common image data which is a common part of a pair of halftone shift image data, and creates halftone positive difference image data and halftone negative difference image data each of which is a difference between the halftone common image data and one of a pair of halftone shift image data. A composite image creator synthesizes the halftone common image data corresponding to an amount of positional deviation, and the halftone positive difference image data or halftone negative difference image data. A controller executes printing on web paper. Since the image data is only synthesized, processing load can be lightened even if printing is performed to restrain positional deviations.

摘要： In printing apparatus, an edge sensor detects a serpentine amount caused by transportation of a web. A predicted waveform data generating unit generates predicted waveform data on the serpentine amount to be produced in the following web in accordance with actually measured waveform data on the detected serpentine amount. A correcting unit corrects a printing position of an image in accordance with a shift amount, and applies a corrected printing position to a printing head. Here, the shift amount is determined with the shift amount determining unit in accordance with the predicted waveform data. Accordingly, the shift amount is determinable in accordance with the actually measured waveform data on the serpentine amount detected with the edge sensor more accurately than that through a method in which a shift amount is directly determined. This allows suppressed misregister.

摘要： A base material processing apparatus includes a first detector, a second detector, and an arithmetic unit. The first detector intermittently detects the position of the edge of the base material in the width direction at a first detection position to acquire a first detection result (Ra). The second detector intermittently detects the position of the edge of the base material in the width direction at a second detection position located downstream of the first detection position to acquire a second detection result (Rb). The arithmetic unit calculates a transport error of the base material by comparison between the first detection result (Ra) and the second detection result (Rb). The controller changes detection timing of at least one of the first detector and the second detector.
