Abstract: In a color management method for a printing press, a color chart formed from a plurality of patches is printed by multi-color printing using the printing press and a plurality of ink colors. Each of the patches has a predetermined combination of dot area percent of the ink colors. The printed color chart is automatically scanned using a calorimeter to sequentially obtain color data of all the patches. A first profile representing a color reproduction characteristic of the printing press is generated on the basis of the obtained color data of the patches and the dot area percent of the ink colors set in the patches. A color management apparatus is also disclosed.

Abstract: In a color management method for a printing press, the first profile representing color reproduction characteristics of a first printing press is generated using color data of a number of patches printed by the first printing press and the dot area percent of each of a plurality of ink colors defined for each patch. The second profile representing color reproduction characteristics of a second printing press is generated using color data of a number of patches printed by the second printing press and the dot area percent of each of a plurality of ink colors defined for each patch. The dot area percent of each ink color to be used to print a printing product by the second printing press is obtained on the basis of the first and second profiles. A color management apparatus for a printing press is also disclosed.

Abstract: In a color management method for a printing press, colorimetic values of a first patch for generating a profile printed by the printing press are measured, so that a printing press profile representing a color reproduction characteristic of the printing press is generated from the measured colorimetic values of the first patch and a dot area percent of each ink color predetermined in correspondence with the first patch. Colorimetic values of a second patch for determining stability of the printing press printed by the printing press are measured. The measured colorimetic values of the second patch is compared with colorimetic values, in the printing press profile, having a dot area percent substantially equal to a dot area percent of each ink color predetermined in correspondence with the second patch. A warning is generated on the basis of a comparison result. A color management apparatus for a printing press is also disclosed.

Abstract: A weighing-packaging-pricing apparatus has a roll supporting device to rotatably support a film roll, a film transporting device to pull a stretch film from this film roll and to transport a stretched film sheet to a packaging station, a weighing device for weighing and measuring the dimensions of an object on a tray to be packed while it travels to a lifter which lifts the object to the packaging station and pushes it against the stretched film sheet, and a folding device for folding edge sections of the film sheet to form a package. The folding device includes transversely moving plates for folding side edge sections of the film sheet, and the motion of these plates is controlled according to the size of the tray to be packaged.

Abstract: A video signal recording/reproducing apparatus includes a recording medium having a video track and an audio track separately formed, wherein a video signal is recorded in the video track and an audio signal to be multiplexed and a discrimination signal of a low frequency and a low level representing the kind of multiplexing thereof are recorded in the audio track. Decision is made of the kind of multiplexing of the audio signal, such as a bilingual mode, a stereo mode or a monaural mode, as recorded in the audio track, in response to the descrimination signal reproduced from the audio track and a multiplexed audio signal is produced in response to the decision signal representing the kind of the audio signal and the audio signal reproduced from the audio track.
