摘要:
El método comprende: a) desplazar linealmente un cilindro de impresión (2) o un cilindro entintador (3) hacia un cilindro de contrapresión central (1 ), haciéndolos girar, activa o pasivamente, y monitorizando su par de giro; b) detectar un cambio significativo del valor de dicho par de giro en relación al valor medio del par de giro, en correspondencia con un primer punto de contacto entre los cilindros; y c) continuar dicho desplazamiento lineal en aproximación al cilindro de contrapresión central (1 ), monitorizando el incremento del par de giro hasta encontrar una variación significativa del incremento del valor medio del par de giro, que se toma como indicativa de un punto óptimo de presión (J2). La máquina impresora está adaptada para implementar el citado método.
摘要:
The method comprises: a) linearly moving a printing roll (2) or an inking roll (3) towards a central, counterpressure roll (1), causing said rolls to rotate, actively or passively, and monitoring the torque thereof; b) detecting a significant change in the value of said torque as compared with the mean torque value, in correspondence with a first point of contact between the rolls; and c) continuing said linear movement towards the central, counterpressure roll (1), monitoring the increase in torque until there is a significant variation in the increase in the mean torque value, which is taken to be indicative of an optimum level of pressure (J2). The printing press is designed in order to implement said method.
摘要:
The method comprises carrying out the following steps: a) capturing information in respect of at least one image printed by said printing press; and b) comparing said captured information on said printed image with at least some digital-format information predetermined prior to printing, or pre-printing digital information, which includes at least one part of the image to be printed. The method comprises adjusting pressures and/or the register of one or more printing units of the printing press using, as a minimum, the result of the comparison in said step b). The press is designed in order to implement the method.
