Abstract
An elongated material such as a cable (20), for example, is provided with a repetitive pattern of a marking (40) which provide information to an observer. Each marking includes intentionally discernible indentations or recesses (33--33) which are formed in plastic material comprising an outer covering (32) of the elongated material. Further, each indentation is filled with a pigmented material (50) which provides a desirable color contrast with the color of the outer covering. The filling material must have a melt viscosity which allows it to be flowed easily into the indentations, yet be retainable in the indentations during handling of the elongated material such as during installation of a cable.
