Abstract
In the regions in the check pattern image where the stripe is formed, the density of the region with higher density has a density value lower than the density value in the case without occurrence of the color mixing and the density of the region with lower density has a density value higher than the density value in the case without occurrence of the color mixing. Regarding this difference in the density value, determination on whether or not density unevenness caused by the color mixing or the landing position deviation occurs is made by using a threshold value and a threshold value different from that.
