摘要： A method and an apparatus for exposing light-sensitive materials, including a first light beam conducted from a light source with the wavelength lambd1 to a first exposure point on the light-sensitive material via an optical system. This system has at least one input end and one output end as well as at least one reflecting or transmitting rotating optical element arranged relatively to the optical output end, wherein at least one additional light source generates an additional light beam with a wavelength lambdx which is different from lambd1. The additional light beam with the wavelength lambdx is conducted via the input end of the optical system to the output end of the optical system, so as to be geometrically coincident with the first light beam at the output end of the optical system, the additional light beam being conducted from there to an additional exposure point on the light-sensitive material inside the image setter drum in dependence on lambdx or the mutual difference between the wavelength DELTAlambd, said light beams being conducted completely or partly from the input end of the optical system via one or more light guides, preferably optical fibers, to the output end of the optical system.

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： Vertical rotating-drum scanners, with a fixed or replaceable drum fitted on one side, for scanning direct-view images or transparencies must not only ensure vibration-free rotation of the drum but must also have a very compact design. The invention meets both requirements by using a controlled, direct asynchronous drive which avoids jitter caused by transmission equipment such as gearing of any kind, the drive rotor being designed as a hollow shaft which is also the scanner-system axle. The hollow-shaft design enables the light for the internal illumination of the drum to be guided along the hollow shaft, thus saving space.

摘要： Print heads are formed with spaced subheads having nozzles such that all of the lines or pixel rows on a print medium such as a sheet of paper are printed by scanning of the print head along the face of the sheet. The head structures include three subheads, each having nozzles for printing one or more adjacent lines with the subheads being spaced the same number of lines apart as the number of lines each prints; and three subheads spaced the equivalent of seven lines apart, each subhead having three nozzles spaced at the equivalent of alternate lines. The heads are advanced between scans by an equivalent number of lines generally equal to the number of nozzles in the head, whereby all print lines are addressed only once. Apparatus for printing includes the use of pointers in registers to keep track of head structure and location on a print medium for calculating print addresses. A partial page memory is used which wraps around to the beginning from the end. A positive printer carriage position encoder uses an index marker located in the middle of a strip of incremental markers. Sensing of the index marker resets an up/down counter with a value that gives a positive value for all count conditions.

摘要： A method of compensating the interval of a plurality of pixels to be simultaneously recorded on a recording surface. The plurality of pixels are recorded by a plurality of beams whose light intensity distributions partially overlap with one another on the recording surface and the pixel whose position should be compensated is selected. The light quantity ratio of the plurality of beams for recording the pixel is changed. Since the light quantity is changed, the peak of the density of pixel is shifted on the side of the beam of a large light quantity so that the interval between the pixels can be compensated.
摘要翻译：一种补偿要同时记录在记录表面上的多个像素的间隔的方法。多个像素被记录在记录表面上的光强度分布彼此部分重叠的多个光束并且选择其位置应被补偿的像素来记录。用于记录像素的多个光束的光量比被改变。由于光量改变，像素的浓度的峰值在大光束的一侧移动，从而可以补偿像素之间的间隔。
