摘要: Provided is a container including a container body and an image on the container body. The image includes a plurality of dented portions and non-dented portions. A visibility value of the image represented by Mathematical formula (1) below is greater than or equal to a predetermined value. Visibility value=b0·L*0·(1−exp(b1·ΔL*)) Mathematical formula (1) In Mathematical formula (1), L*0 represents a luminosity of the image. ΔL* represents a difference between the luminosity of the image and a luminosity of any other portion than the image, b0 represents a positive real number, and b1 represents a negative real number.

摘要: Provided is a container including a container body, and an image on the container body. The image includes a plurality of dented portions and non-dented portions. Each of the dented portions is formed of a plurality of processed portions. The plurality of processed portions are disposed linearly, contacting or overlapping each other along a first scanning direction. A width of each of the dented portions in a second scanning direction orthogonal to the first scanning direction changes cyclically along the first scanning direction. Each of the dented portions has bossed portions along the first scanning direction between adjoining ones of the processed portions.
