A hot stamping cylinder for webs includes a mounting cylinder, a longitudinal channel extending running along the substantial entirety of the length thereof. A flexible substrate plate includes a leading edge flange substantially parallel to the flexible substrate plate and offset a distance substantially equal to the depth of the channel. A trailing edge flange is also provided which is substantially parallel to the flexible substrate plate and offset a distance substantially equal to the depth of the channel. A layer of silicone material is positioned on the flexible substrate plate where the layer of silicone material has a relief pattern thereon which corresponds to a desired stamping pattern. A longitudinal clamp resides in the channel and retains the leading edge flange and the trailing edge flange within the channel thereby securing the substrate plate, with silicone relief pattern thereon, to the mounting cylinder in preparation for use in a web hot stamp operation.
