Abstract
A method for providing identificational coloration on a paper ply of a yarn tube or similar article, the invention comprises reverse printing of a dye onto a pervious paper which is coated on the outer surface with a transparent polymer coating, the coating being impervious to the dye. According to the invention, the dye penetrates through the paper but not through the polymer coating, the informational coloration and/or pattern of the dye being clearly visible through the polymer coating to allow ready identification of the yarn or other material carried on the tube.
