Embodiment Construction

[0023] In the following, reference will be made to Figure 1 to Figure 13 Embodiments of the present invention will be described.

[0024] figure 1 is an overall view showing an embodiment of a multifunction printer (hereinafter referred to as MFP) to which the present invention is applied. The MFP 1 includes: an acquisition unit 2 for acquiring pixel values; a storage unit 3 for storing position information on the joint portion of the head unit and head characteristic information about the head; a prediction unit 4 for , position information, and head characteristic information to seek the output characteristics of the printed material; a direction transforming section 5 for transforming the image into an appropriate direction based on the result sought by the predicting section 4; An inkjet head unit that ejects ink onto a recording medium such as paper to capture image data.

[0025] Furthermore, the MFP 1 is connected to a terminal such as a personal computer (hereinaft...

Abstract

An inkjet recording apparatus comprising; a recording portion for recording an image on a recording medium, said recording portion having an inkjet head unit including a plurality of connected line heads, an acquisition portion for acquisitioning pixel information indicated by a pixel of a document, a memory portion for storing position information of a joint portion of said head unit and head property information, a prediction portion for seeking output property by each printing directions based on said pixel information, said position information and said head property information, a direction conversion portion for converting a printing direction to reduce influence of the joint portion of said head unit on the document based on the output property acquired by said acquisition portion and said direct conversion output to said recording portion.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority to US Provisional Application No. 61 / 288,636, filed December 21, 2009. technical field [0003] Embodiments described herein generally relate to inkjet recording devices. Background technique [0004] In recent years, in order to achieve high-speed printing / recording, a line-head is formed by connecting a plurality of inkjet heads, and recording devices of this type have been introduced on the market, which utilize one scanning path or less The scan path records an image on the recording material. [0005] Such a recording apparatus corrects recording unevenness of each ink nozzle by performing complicated multi-scan or the like due to errors in recording accuracy related to ink ejection characteristics of each nozzle. In addition, when a plurality of inkjet heads are connected, due to inconsistencies related to fixed position accuracy between the heads, inconsistencie...
