Resumen
Printing with inkjet technology has found new forms of application in the industry and in this article we study this technology focused on printing on non-flat surfaces. Since there is no print history over distances greater than 1 mm due to the rupture phenomenon, an initial quality standard is defined to measure achievements in a relative manner. An interactive method is used that requires the user to approach the machine in multiple analyzes of different types. The first approach is a mathematical model this model was constructed to predict the drop distance of the drop in the non-planar substrate with respect to the planned one in the flat substrate, taking into account that most of the drops fall to different heights presenting a greater or lesser state of development the phenomena present in the flight. The results allow to initiate a process of compensation that avoids the distortion of the figure to improve the printing resolution. The results are validated using a relative quality through industrial ink-jet printer with heads capable of injecting functional fluids. The initial result indicates that in standard surface printing with print relative quality already defined, it can be used only for low resolution formats with thick lines, and the result can be improved when the original figure is treated by compensating the distance between the numerical prediction and the initial objective. © 2019, Springer-Verlag France SAS, part of Springer Nature.
