摘要： PROBLEM TO BE SOLVED: To reduce a plate making time and plate materials and to do printing efficiently. SOLUTION: Page description data in which raw materials 61 which are printing contents are associated with each other are divided into a fixed part 62 which is printing contents common to a plurality of kinds of printed matter and variable parts 63a, 63b which are printing contents peculiar to each kind of the printed matter and are administrated. When plate making raster data are produced from the page description data, the raster data of each color component are produced from the fixed part 62 and the variable parts 63a, 63b. In plate making printing, with the use of the raster data 67k of a K plate obtained by synthesizing raster data 64y, 64m, 64c concerning three plates Y, M, C obtained from the fixed part 62 and the raster data of the fixed part and the first variable part 63a, the first plate making printing is done. Thereafter, every time when the variable part is changed, printing is continued with only the K plate made/replaced by using the raster data 67k of the K plate obtained by synthesizing the fixed part and the variable parts.

摘要： PROBLEM TO BE SOLVED: To provide a proof forming apparatus with which the color of an objective printed material can be accurately and stably reproduced by using a relatively simple mechanism and dots are easily confirmed, or to provide a method of forming the proof. SOLUTION: The apparatus forms a proof of a printed material as an ensemble of dots on the basis of the digital image data of a multicolor printed material. An area gradation image corresponding to at least one printing color of the printed material is formed of at least two kinds of dots having a density difference of 0.01 to 0.5.

摘要： PROBLEM TO BE SOLVED: To materialize the easy handling of special colors in line drawing data processing. SOLUTION: This image data processing device has a means for inputting processing information such as a work memory 4, a keyboard 7 and the like, a line drawing processing means 15 for executing processes such as color conversion and the like and an indicating dara forming means 11. In the work memory 4, a line drawing file to be processed and further run length data consisting of color numbers and run lengths, a color-in-use table CT, which represents a relationship between the color number including the run length data and the density value of the color-in-use consisting of each color number, and a color-in-use name data representing the correspondence relationship between the specified density of the color-in-use and the signal value of an indicating calorimetric system are stored. The indicating data forming means 11 forms indicating data on the basis of the run length data, the color-in-use table and the color in-use name.

摘要： PROBLEM TO BE SOLVED: To reduce or eliminate artifacts of printed images without depending on an expensive, cost-increasing image processing method and without adding additional hardware to an existing device. SOLUTION: In a method for reducing the naked eye-visible artifact of a color-printed image, the imaging of each plate surface to be used in different color planes is started by using different imaging beams. It is also possible to start the imaging of each plate surface to be used in different color planes by using different sets of imaging beams. The present method does not need the operation of image data. In the method, some error is diffused over the whole printed image to prevent the error from being imaged and or printed, so that the perception of the artifact can be reduced or eliminated.

摘要： PROBLEM TO BE SOLVED: To precisely set an original film to a specific position by providing a positioning means supported by a supporting member and capable of designating at least a pair of points on an original platen. SOLUTION: A position designating mechanism 70 includes four visible lasers irradiation devices 71 to 74 mounted to a transparent light source unit 30b and irradiating visible laser beams to the original platen 20. Among these, two lasers 71, 73 are fixed to the unit 30b and used for designating the position of the register 23a of originals 21a to 21d. The positions of these two lasers 71, 73 on the unit 30b fix the positions of the y-direction of the register 23a of the originals 21a to 21d. The other two lasers 72, 74 are mounted to the unit 30b to be movable in a main scanning direction (y-direction). In addition, as the moving means of the lasers 72, 74, an automatic or manual moving means to be used normally can be used.
