Currently, a mass of digital printing machines emerge in the market, whose brands, norms and types are abundant. Their application in the field of digital printing is increasingly wide. However, after the study on these machines' parameters, the fact that almost no machine can be used in map digital printing is discovered. Therefore, digital printing technique can hardly be used in map digital printing field. This paper analyzes the particularity of map products, pointing out the fact that maps have relatively large breadth and lay rigid requirement on the image-text precision, which should uses high folding strength while low variant paper to print. Current printing machines cannot meet the needs of the above parameters simultaneously, which leads to the blankness in map digital printing field. This paper put forward the needed parameters and chief functions of digital printing machines used in map digital printing, which provides important reference for the printing machine producers and manufacturers to extend the products 'application range.
