Problems solved by technology

[0007] The second problem is the recording speed
[0025] Although the image reproducing / forming apparatus disclosed in JP2000-190473A is suitable for preventing electric charge leakage from the conveyor belt, it does not aim at preventing electric charge leakage occurring due to ink itself ejected or absorbed into paper

Abstract

An image reproducing and forming apparatus comprises a recording head (14) configured to eject liquid droplets of at least one color and capable of bidirectional recording, and a controller (100) configured to control the amount of. liquid adhering to a recording paper (3) so as to reduce color difference occurring in the bidirectional recording. The controller includes a gamma correction unit (133) configured to selectively perform a controlled gamma correction using a controlled gamma value adjusted so as to reduce the color difference or an ordinary gamma correction using an ordinary gamma value.

Description

technical field [0001] The present invention generally relates to an image reproducing and forming device, a printer driver, and a data processing device, and more particularly, the present invention relates to an image reproducing and forming device capable of bidirectional printing while preventing occurrence of chromatic aberration. The present invention also relates to an inkjet type image reproducing and forming apparatus that prevents leakage of charges in a statically attracted paper conveying mechanism. The present invention also relates to a printer driver for processing data in order to prevent chromatic aberration and / or charge leakage in bidirectional recording, and to a data processing device loaded on the printer driver. Background technique [0002] An "inkjet recording device" is a type of image reproducing and forming device. Examples of inkjet recording devices include inkjet printers and facsimile machines or copiers that record using an inkjet mechanism....
