Failed Export - PDF for Print. Everything worked fine during export except that some elements (notably those created using the Warp/Deform feature) didn't stay within the bounds. The warp effect was in a child layer, which exported fine using JPEG export and stayed within the confines of the parent. But with PDF export to Print, the child layer with Warp content overshot the bounds of the parent layer and displayed as a rectangle (bounding box confines).
