击凸讨论（Bump discussion） From design concept to printed material, it is the process of conscious expression and figurative form. The computer screen can accurately display consciousness and even model, but we still cant predict the shape effect. As far as ordinary four-color offset printing is concerned, it is difficult to obtain ideal color reduction in printing. If we choose different printing carriers, we will add special printing technology and effect. Form and appearance can be described as ever-changing, and the complexity of the process can be imagined. Accidental success is rare. Because of the need to have extensive practical experience of designers, and can fully implement the design intent of the printing firm close cooperation, and jointly completed. Not everyone has this opportunity, in fact, whether printed or graphic designer, provider, or more often in the face of such problems and doubts: from the computer screen to print the kind, figurative consciousness and form, the gap between how far? Its really hard to describe in words. Friends who are interested should be patient In the design of printed matter, designers often emphasize only the concave and convex parts, and give them to the printing factory, and ignore the specific requirements of the quality, so that the effect can not be perfect. There are several ways to make smooth even more outstanding performance: first, the laser engraving plate (not as corrosion, artificial carving version) also need to produce a set of intaglio and relief (i.e., male and female mold), such edges more clearly. Second, select the appropriate depth (maximum 2.5 mm) depending on the design requirements and the paper toughness. Third, if more than 10000 copies or more, should choose durable materials as copper plates, plates and ensure the edge is not easy to wear. Process principle A bump process is a three-dimensional effect of paper surface that is higher than or below the surface of the paper by means of a preformed
