摘要:
A recorded image is distorted on a printing plate when an image information for a computer is recorded in the form of a band with a band width of a plurality of image elements on a printing plate wound around a drum. This invention provides an undistorted recording on the printing plate, made possible by an arrangement that has a printing plate wound around a drum in the form of a right circular cylinder, and exposure unit to record image information in the form of a band on the printing plate by means of a light beam, a moving mechanism to move the exposure unit by one band width in the direction of the drum axis in relation to the drum while the drum makes a revolution, an image treating apparatus with the image information stored in the form of a right quadrangle, and an image modulator to rearrange and slant each band of image information readout from said image treatment apparatus by one band width in the opposite direction to the movement of said moving mechanism.
摘要:
A computer-implemented method of generating a glyph in which a plurality of design characteristics are extracted from a target font and a source glyph program is generated using the design characteristics. The source glyph program defines a new glyph that corresponds to a character that is not present in the target font, e.g., the Euro, and is stylistically similar to glyphs of the target font. The new glyph may be added to the target font, it may be rendered on an output device, or it may be saved separately from the target font.

Beschrieben werden Verfahren und Vorrichtungen zum Erzeugen eines Proofsatzes eines digitalen Druckauftrags und Verzögern der Fertigstellung des Drucksatzes so lange, bis der Proofsatz freigegeben ist. Die Erfindung umfasst zudem das Erstellen eines Proofsatzes, der Druckmerkmalsinformationen auf Seitenebene umfasst, die auf dem Proofsatz in einer Wasserzeichenschrift aufgedruckt werden.
摘要:
An inner drum type image recording device is provided which, in exposure of a photosensitive lithographic printing plate, eliminates unnecessary light (reflected scattered light) other than light for main exposure, and eliminates fluctuations in a dot percent. By limiting baffles to a minimum number of positions necessary, fluctuations in the dot percent caused by reflected scattered light are suppressed, and a sufficient space needed for maintenance work on a spinner mirror and the like can be ensured. Further, by making the baffle fan-shaped and disposing the baffle at a periphery of the spinner mirror, light of a subscanning component of reflected scattered light can be reliably blocked.
摘要:
Image scanning apparatus comprises an elongate image support (1) having a curved cross-section. A scanning system (7-10) is positioned radially inwardly of the support for scanning a radiation beam (11) in a circumferential direction across a record medium (2) on the support. Relative movement is caused between the support and the scanning system parallel with an axis of the support. At least one pair of axially extending resilient baffles (12-16) is mounted on axially opposed sides of the scanning system and extends close to the support to as to impede radiation reflected by a record medium on the support impinging on another part of the record medium.
