/* Open-DTF — hoja de pruebas de imprenta.
   Mundo: el pliego que un diseñador revisa antes de imprimir. Papel estucado blanco, tinta K, tintas de proceso
   (C, M, Y) como campos de color a escala de página, marcas de corte y registro, barra de color y línea de pie
   de prueba. El lienzo 3D (fijo) es el pliego impreso; las secciones sólidas lo tapan. */
