  • Publication number: 20250144931
    Abstract: When a foaming promotion component is applied to a recording medium including a foaming layer containing foamable particles to foam, a forming height of an edge of a forming region may decrease. An image processing apparatus detects an edge pixel located inside the forming region at a border of the foaming region with a non-foaming region and increases an amount of application of the foaming promotion component, thereby being able to prevent a decrease in the forming height.
