    摘要: Calibration data is generated by an external device, and calibration of a printer is performed based on the calibration data. When a printer detects change in printing conditions, such as temperature, it transmits a calibration request and information on change in printing conditions (e.g., measured temperature) to an external device. The external device generates calibration data (e.g., data used for correcting density) on the basis of the information on the printing conditions, and calibration of the printer is performed on the basis of the calibration data.

    摘要: One page is segmented into a plurality of bands (segments), and dot image data is generated on a per band basis from given information (graphic object). High-speed printing with a small-sized memory is achieved by allowing one band to be converted into dot image data and dot image data for another band to be transmitted to a printer, concurrently in parallel. When the conversion of a band to dot image data needs more time than is available for printing one band, or when the data quantity of object per page exceeds an allocated memory area, an object corresponding to a degraded image data is generated, and then the degraded image data is generated on a per band basis based on the resulting object.

    摘要: A vacuum contact printing apparatus includes: a transparent plate on which an original film and a photosensitive material are placed, an overlay sheet which covers the transparent plate, a friction reducing sheet provided between the transparent plate and the overlay sheet, and an evacuating device for removing air from between the overlay sheet and the transparent plate. The transparent plate is covered with the friction reducing sheet prior to or simultaneously with the covering of the original film and photosensitive material placed on the transparent plate wiht the overlay sheet. Frictional force caused by the change of the form of the overlay sheet can be prevented from being applied to the photosensitive material because the overlay sheet smoothly slides on the friction reducing sheet.
