Abstract

DISPOSITIVO PARA EL CONTROL DE PANTALLAS SERIGRAFICAS. PERMITE NOVEDOSAMENTE UN CONTROL DIRECTO SOBRE PANTALLAS SERIGRAFICAS (1) PARA POSIBILITAR UNA COMPARACION RAPIDA Y PRECISA DE LA MISMAS. DICHA COMPARACION SE EFECTUA MEDIANTE LA DETERMINACION DEL AREA LIBRE DE PASO Y/O CERRADA DE CADA PANTALLA (1) O ZONA DE PANTALLA A COMPARAR; SIENDO DICHO AREA LIBRE EL CORRESPONDIENTE A LA ZONA DE LA SUPERFICIE QUE DEBE QUEDAR CUBIERTA DE TINTA SERIGRAFICA EN EL SOPORTE QUE CORRESPONDA TRAS UN PROCESO DE IMPRESION. CUENTA CON UNA FUENTE PLANA DE LUZ DIFUSA (2) SOBRE LA QUE SE COLOCARA LA PANTALLA (1) A MEDIR. SOBRE ESTOS ELEMENTOS (1 Y 2) SE DISPONE UN SISTEMA DE LENTES DE AUMENTO (3) CONECTADO A UN BLOQUE (4) QUE SE COMPONE A UNA CAMARA CCD CONECTADA A UN ORDENADOR CON VARIOS MONITORES QUE ANALIZA MEDIANTE PROGRAMAS ADECUADOS LA IMAGEN PROVINIENTE DE DICHO SISTEMA (3) PARA PROPORCIONAR EL VALOR DEL AREA MENCIONADA ANTERIORMENTE.DEVICE FOR THE CONTROL OF SERIGRAPHIC SCREENS. IT ALWAYS ALLOWS DIRECT CONTROL ON SERIGRAPHIC SCREENS (1) TO MAKE A QUICK AND ACCURATE COMPARISON OF THEM POSSIBLE. SUCH COMPARISON IS MADE BY DETERMINING THE AREA FREE OF PASS AND / OR CLOSED OF EACH SCREEN (1) OR SCREEN AREA TO COMPARE; BEING SUCH A FREE AREA CORRESPONDING TO THE AREA OF THE SURFACE THAT SHOULD BE COVERED BY SERIGRAPHIC INK IN THE SUPPORT THAT CORRESPONDS AFTER A PRINTING PROCESS. IT HAS A FLAT SOURCE OF DIFFUSE LIGHT (2) ON WHICH THE SCREEN (1) TO BE MEASURED. ON THESE ELEMENTS (1 AND 2) A SYSTEM OF INCREASE LENSES IS PROVIDED (3) CONNECTED TO A BLOCK (4) THAT IS COMPOSED TO A CCD CAMERA CONNECTED TO A COMPUTER WITH SEVERAL MONITORS THAT ANALYZES THROUGH APPROPRIATE PROGRAMS THE IMAGE PROVIDED BY SUCH SYSTEM (3) TO PROVIDE THE VALUE OF THE AREA MENTIONED ABOVE.
