Patent number: 8625092Abstract: An apparatus (10) measures a spectral distribution of a translucent printed product (12) produced with a printing device. The apparatus (10) has an illuminating source (20) for illuminating the printed product (12), an optoelectronic measuring means (32) for measurer the transmittance value of a section of the spectrum of the light (26) transmitted through the printed product (12), an optical disperser (28) for dispersing the wavelengths of the transmitted light (26), and a light entry gap plane that is definitive for the disperser (28). The light entry gap plane that is definitive for the disperser (28) is created by the surface of the printed product (12) to be examined.Type: GrantFiled: September 8, 2009Date of Patent: January 7, 2014Assignee: Theta System Elektronik GmbHInventors: Christina Tatarczyk, Joachim Tatarczyk

Patent number: 8237828Abstract: A device for inspection of print products (36) produced by a printing machine (10) is provided with a first camera (48) being directed to an inspection field to be checked. At least one further camera (50) is provided being directed at least partially (58) to the same inspection field (54) being checked already by the first camera (48).Type: GrantFiled: April 24, 2006Date of Patent: August 7, 2012Assignee: Theta System Elektronik GmbHInventors: Christina Tatarczyk, Joachim Tatarczyk

Patent number: 7787125Abstract: An apparatus (10) measures a spectral distribution of a printed product (12) produced with a printing device. The apparatus (10) has an illuminating source (20) for illuminating the printed product (12), an optoelectronic measuring means (32) for measurer the reflectance value of a section of the spectrum of the light (26) reflected from the printed product (12), an optical disperser (28) for dispersing the wavelengths of the reflected light (26), and a light entry gap plane that is definitive for the disperser (28). The light entry gap plane that is definitive for the disperser (28) is created by the surface of the printed product (12) to be examined.Type: GrantFiled: April 2, 2007Date of Patent: August 31, 2010Assignee: Theta Systems Elektronik GmbHInventors: Christina Tatarczyk, Joachim Tatarczyk -
