IMAGE-FORMING DEVICE, IMAGE-FORMING METHOD AND FORMED IMAGE PRODUCT

摘要

If the upstream section and the downstream section in the direction of conveyance of a substrate (9) of two selected ink-discharging sections (head assemblies (42)) that are disposed side by side in said direction of conveyance are respectively defined as the first ink-discharging section and the second ink-discharging section, the inkjet printer (1) discharges from the first ink-discharging section a first ink for which the surface tension of droplets adhering to the substrate (9) decreases over time. The second ink-discharging section discharges a second ink for which the surface tension of droplets when adhering to the substrate (9) is approximately equal to the surface tension of the droplets of the first ink adhering to positions adjacent to the second ink droplets. The surface tensions of the first ink droplets and the second ink droplets adhering at positions adjacent to each other are thereby approximately matched, making it possible to limit bleeding and shifting of the boundary position at the boundary between the first ink regions and the second ink regions on the substrate (9).
