1. A method of producing a sustainable laser-scribed graphic image on a cotton garment, comprising:

  • providing a cotton garment containing a dye imparting an appearance of a first color other than white to the cotton garment;

    selecting an area of the dyed cotton garment comprising less than the entire area of the cotton garment where an image is to be formed pre-treating said area but less than all of the cotton garment by spraying said area with a curable pre-treatment material;

    curing the pre-treatment material on said pre-treated area of the cotton garment; and

    laser scribing a graphic image in the pre-treated area, the graphic image having a second color sufficiently different in appearance from the first color to establish a visibly perceivable contrast between the first and second colors,wherein the cured pre-treatment material improves sustainability of the visibly perceivable contrast against repeated washings.
