Definitions

  • the materials that predominate lately refer to those used in completely rigid or semi-rigid suitcases, which provide a certain degree of flexibility, such as ABS (Acrylonitrile Butadiene), PC (Polycarbonate) or PP (Polypropylene) among others, which provide greater safety of content, and four wheels for greater comfort when traveling. On these materials, it is necessary to include the different colors, designs, brands, prints or customizations required to suit the consumer's taste.

  • printing means configured to stamp an ink print in a print area of a single determined printing plane
  • height adjustment means coupled to the printing means, configured to regulate the height of the printing means and the height of the single printing plane
  • leveling means attachable on the support means, configured to receive one or more suitcases on at least one of their faces, such that the surface of the opposite side of each suitcase is leveled in the single printing plane;
  • Obtaining leveling means comprises, according to one of the embodiments of the invention, obtaining a male mold that reproduces the inner contour of the suitcase, where the male mold comprises a first body configured to receive the inner face of the front part of the suitcase and a second body configured to receive the inner face of the back of the suitcase, so that, in a completely open position of the suitcase, the front and rear outer faces are leveled in the single printing plane and facing print media
