击凸评论辩论(国外英文资料).doc

击凸讨论 From the design concept to the printed object, it is the process of conscious expression and form. Computer screens can be precise and even model, but we still cant predict the effect of the shape. Just for ordinary four-color offset printing, if can get the ideal in the printing color reproduction is not easy, if you choose a different printing carrier, add special printing technology and effect. It is difficult to imagine the complexity of the process. For designers who need to have a lot of practical experience, they work closely with the printers who are able to fully implement the design intent. Not everyone has the chance, in fact, no matter printing provider, or a graphic designer, more time is often in the face of such problems and confusion: from the computer screen to the printing material, representational consciousness performance and form, the gap between how far is it? Its really hard to describe in words. Be patient with your interested friends... In graphic print design, designers tend to emphasize concave and convex part and to the printing shop, while ignoring the quality of the specific requirements are put forward, make the effect is not perfect. There are several ways to make the performance of the concave and convex better: first of all, should be used in laser engraving plate (as far as possible need not corrosion artificial cut), at the same time need to make a set of gravure and letterpress (that is, the male die and female die), so that more fine clear edges. Second, choose the proper depth (maximum to 2.5 mm) according to the need of the design and the toughness of the paper. Third, if you print more than 10, 000 copies, you should choose a durable copper material for printing, which is strong and ensures that the corners are not worn easily. Process principle Concave and convex processes are the three-dimensional effects of the surface of the paper forming above or below the surface of the paper by prefabricate sculptural models and
