    摘要: In an image forming apparatus, an object surface (14) is disposed facing one end face of a rod lens array (10), while an image surface (16) is disposed facing the other end face thereof. A lens working distance of the rod lens array on the object side is substantially equal to that on the image side. An actual object-image distance Tco is set between the conjugate length TC1 at which the average value MTFave of the MTF of the rod lens array in the lens array direction is maximized and the conjugate length TC2 at which the ΔMTF (= (MTFmax - MTFmin)/MTFave) is minimized, and a shift quantity ΔC (= |TCo - TC1|) is set within 0mm

    摘要: Es wird eine punktweise Bebilderung von Druckflächen mit wenigstens einem Laserstrahl, welcher relativ zur Druckfläche bewegt wird, vorgeschlagen, dessen aktive Fleckgröße, d. h. diejenige Fläche, auf welcher die Intensität die Schwellenintensität zur Bebilderung überschreitet durch Variation der Laserleistung veränderbar ist. Mit einem Entfernungsmesser werden Abweichungen der Istlage von der Sollage von der Druckfläche zum Strahlfokus detektiert. Durch eine entsprechende Erhöhung der Laserleistung oder Belichtungszeit wird auch mit dem aufgeweitetem Strahl die Bebilderungsschwellenintensität auf vorgegebener Fläche im tatsächlichem Abstand erreicht.

    摘要: A method of printing on a print medium (11) with an ink jet printer (13) uses a first color ink, a second color ink and a black ink. An image area on the print medium has a plurality of pixel locations. Print image data (24) indicate on of a presence and on absence of the first color ink, the second color ink and the black ink at the plurality of pixel locations. A subset of the print image data is defined. A determination is made as to whether the subset of print image data indicates: (1) a presence of the first color ink and/or the second color ink within the subset and a presence of the black ink within the subset; (2) a presence of each of the first color ink and the second color ink within the subset at a same corresponding pixel location; and/or (3) a presence of the first color ink and/or the second color ink within the subset at a number of corresponding pixel locations exceeding a threshold value.

    摘要: A rod lens array to be used for an optical printer comprises a plurality of rod lenses arranged densely in array, an opaque substance filled in the gaps separating the plurality of rod lenses, and a pair of side panels sandwiching the plurality of rod lenses and the opaque substance. The rod lens array satisfies the requirement as defined by the formula: S where P is the resolution of the optical printer expressed in dpi, Z is the length of the rod lenses expressed in mm, L is the conjugate length of the rod lenses expressed in mm, and S is the flatness of the surfaces of the side panels bearing the rod lenses.

    摘要: An optical printer head (1) capable of preventing catching between a filter holder (8) and a luminous tube (2) to prevent production of dust and attaining replacement of the luminous tube (2) without exposing filters to an ambient atmosphere. A filter holder (8) is arranged separately from the light source (2) and a selfoc lens array (14), to prevent production of dust from the filter holder (8) due to contact of the filter holder (8) with the light source (2) and the selfoc lens array (14). A base (9) is arranged so as to receive only the filter holder (8) from being exposed to an ambient atmosphere, resulting in dust being kept from adhering to the filters. A pair of light passages (12,13) are formed on a light path and closed with a light-permeable cover (15) to sealedly close the base (9), thereby preventing dust from intruding into the base (9) during replacement of the light source (2).
