AI Technical Summary
Technical Problem
In inkjet image forming apparatuses, high-speed printing mode results in a reduction in image quality, particularly in image density and color gamut, due to the ink ejection area being halved.
Method used
By reducing the resolution of image data along the transport direction in high-speed printing mode and increasing the ink ejection volume according to the transport speed, while adjusting the UV light irradiation state, image quality and density are maintained.
Benefits of technology
While increasing the conveying speed, it effectively suppresses image quality degradation, ensuring that the image density and color gamut are similar to the standard printing mode, thus achieving high-speed printing.

Abstract
The present application provides an image forming apparatus capable of realizing high-speed printing while suppressing deterioration of image quality to a minimum, a control method of the image forming apparatus, and a storage medium. An inkjet image forming apparatus includes: an operation mode setting section that accepts selection of a print mode at the time of executing a print job from among a standard print mode and a high-speed print mode in which printing is executed in a state in which a conveyance speed of a recording medium is increased compared to the standard print mode; an image data conversion section that converts image data of a print target into image data that is low-resolutionized in a conveyance direction at the time of the high-speed print mode; and an ink ejection amount decision section that decides, at the time of the high-speed print mode, an ejection amount of ink ejected from an inkjet head toward each pixel position of the recording medium based on the converted image data so that the ejection amount of ink corresponding to the density of pixel data of the image data is increased in accordance with the conveyance speed.
