The invention relates to a method for printing an embossment microstructure with a positioned color register, in particular to a method for the integrated online printing of an embossment type optical microstructure layer which is positioned and nested with an ink color. The method comprises the following steps: taking a microstructure area as a special color for printing; printing a molding ink at a specified position; in the state that the ink area is not completely dried and solidified, attaching and die-casting the ink area in a positioning mode by an embossment microstructure mother set roller on a next printing plate roller so that the ink is embedded in an embossment microstructure groove on a mother set; and solidifying and molding a hinge for drying the ink in a coating area of a printing material and a microstructure image, wherein the embossment shaped microstructure on the mother set roller is completely copied to the ink surface of a printing stock in a mirror image mode, and a copying molding area serves as a color register printed at the specified position and can be connected with front and back printing colors to form a +/-0.15 millimeter printing registration accuracy. The method can achieve the positioned color register with a common printing and the accurate positioning of pattern and ink printing on the mother set.

A method and apparatus for correcting a color registration are provided for improving the quality of images of an image forming apparatus. A surface condition is estimated of an intermediate transfer belt used to correct a color registration. A determination is made as to whether an abnormal section exists on the intermediate transfer belt. Location information is stored regarding the abnormal section on the intermediate transfer belt, if the abnormal section exists. A mark for color registration correction is formed on a normal section, other than the abnormal section. The color registration is corrected using the mark. Accordingly, if a partially inferior section appears in the intermediate transfer belt and a mark is not normally formed, the color registration is successfully corrected.

The invention provides film-free computer direct plate making equipment and a making method. The equipment comprises an exposure light source, a print image imaging device and a printing plate carrying device, which are arranged coaxially; the exposure light source is used for irradiating light to cure a photosensitive material loaded on a printing plate; the print image imaging device is used for forming a target image to replace a film, and the target image masks the light from the exposure light source so that a corresponding exposure image is formed on the printing plate; and in order to improve the exposure efficiency and the plate making efficiency, the print image imaging device is provided with a light guide layer for trimming non-uniform exposure light to uniform parallel light. Meanwhile, a plate making process formed by the plate making equipment can adapt to the plate making requirements of high precision and low cost.

The invention discloses a high-speed base paper digital pre-printing machine and aims to solve the problem that an existing pre-printing machine is not suitable for small-batch orders. The high-speedbase paper digital pre-printing machine comprises an outer cover, an active force mechanism, an ink stack ink wiping mechanism, a printing mechanism, a position detection mechanism, a drying mechanismand an electric control system, wherein the active force mechanism comprises an active force motor, a central roller and a tensioning roller, and the printing mechanism comprises a spray head, a trolley plate, a negative pressure cylinder, a primary ink box, a secondary ink box and a trolley motor. The high-speed base paper digital pre-printing machine is reasonable in design, the problem of small-batch orders can be solved through cooperation of components such as the active force mechanism, the ink stack ink wiping mechanism, the printing mechanism and the like, so that the high-speed basepaper digital pre-printing machine is suitable for both large-batch orders and small-batch orders; the high-speed base paper digital pre-printing machine integrates multiple colors to the trolley plate, the printing width is not limited, and the application range is wide; the high-speed base paper digital pre-printing machine adopts the design of the central roller, the base paper clings to the central roller, wrinkles and deformation are avoided, the color matching is more accurate, printed patterns are more delicate, and the high-speed base paper digital pre-printing machine is suitable forhigh-end customers.

An electrophotographic image forming apparatus for enhancing color registration is provided. The electrophotographic image forming apparatus includes a developing unit including a photosensitive medium, an image transferring device, and a paper feeding device. The image transferring device includes a pair of conveying rollers, a conveying belt, and a plurality of transfer rollers. The conveying belt is supported by the conveying rollers and rotates around the conveying rollers and conveys a recording medium by attaching a recording medium to a surface thereof. The plurality of transfer rollers are disposed inside the conveying belt and form a transfer nip between the recording medium and the photosensitive medium. The paper feeding device provides the recording medium to the image transferring device. The force of the image transferring device that maintains the position of the recording medium with respect to the conveying belt during image transferring is equal to or greater than the maximum force applied to the recording medium by the paper feeding device.
