活版印刷法是设计工作方法上的一项重大革新,它的主要特点是将工艺布置、制图、插图、晒图并成一道工序。据初步估计出图效率比原来的设计方法要高三十倍左右;同时节省了制图员、描图员,还节省了大量的晒图纸;此外,图纸的质量大大提高,图面非常清晰美观。 The letterpress printing method is a major innovation in the method of design work. Its main feature is to combine process layout, drawing, illustration, and blueprinting into one process. According to a preliminary estimate, the efficiency of the map is about 30 times higher than that of the original design method. At the same time, cartographers and plotters are saved, and a large number of blueprints are saved. In addition, the quality of the drawings is greatly improved and the drawings are very clear and beautiful.
