A seamless texture tile is a repeating pattern. The intended use is to step and repeat it to the size desired rather than to enlarge it. With this approach there is no distortion of loss of resolution and the quality is exceptional. The tile has a pixel dimension of 3,600 x 3,600 pixels. Thus at a print resolution of 300 DPI it measures 12" x 12" or at 72 DPI it measures 50" x 50".
If, for example, you need the carbon fiber to be 4 feet wide and 2 feet high, you would step and repeat the original 4 times horizontally and twice vertically to arrive at the desired size at 300 DPI. The following image illustrates what I am describing. It shows a 2 x 4 tiling with the final tile about to be placed in the sequence.
