When potatoes are packed in containers, such containers shall be branded, marked, labeled, or stenciled in a plain and legible manner with the name of the grade as hereinbefore provided for and to which such potatoes conform. When the containers contain one hundred (100) pounds or more, such brands, marks, labels, or stencils shall be in two (2) inch or larger block type letters, but when the containers contain less than one hundred (100) pounds, the brands, marks, labels, or stencils may be in proportion to the size of the container.
The brands, marks, labels, or stencils shall be branded in a color or colors to contrast with the color of the container, and shall be on the same side of the bag or container as the private brand or other printing on the container, and shall be in such position as to be readily legible with the other printed matter or design on the container. On one hundred (100) pound bags, the grade designation shall not be nearer than six (6) inches to the top or bottom of the bag; on bags containing less than one hundred (100) pounds, the grade designation shall be placed in position in proportion relatively to the one hundred (100) pound bag.
