Computerized laser positioning type color name-card offset printing machine of the present utility model, its operation principle is: before printing, want earlier Pattern and character and paper position on the calibration PS plate make it every kind of color and all can be imprinted on requirement when different operations printings The position. This calibration operation is exactly common saying contraposition work in the press. Contraposition work at first is calibration PS plate, the PS plate On character pattern by the sensitization film by photosensitive facture to the PS plate, usually when sensitization, do the school, position Mutatis mutandis datum line. After the PS plate was contained on the cylinder 3, the laser beam 4 that sends by laser generator 6 was as benchmark Line overlaps datum line on the PS plate 49 with laser beam 4 datum lines, just finished the installation adjustment of PS plate. School then The position of accurate paper. Earlier start is rotated offset press, is contained in the PS plate 49 that cylinder 3 scribbles China ink and vertically advances at paper 53 The time, PS plate 49 rolls on paper 53 surfaces, and pattern and character is printed on the paper 53, and what namely be commonly called as in the so-called printing industry beats Sample. After the first time, specimen page came out, just can read the position of printing pattern and character on the paper by pantograph (mirror) and be The no requirement on the position if be not inconsistent, gets final product reading horizontal and vertical offset values, by regulating the level of paper Displacement and length travel reach requirement. Horizontal displacement is adjusted with horizontal position transposition joint device 20, and the length travel amount is passed through Push away paper coaster fine setting button 17 and adjust, because printed patterns is imprinted on the branch that is equipped with left-right and front-back on the paper from normal bit, so aobvious Show that displacement also has with it corresponding positive and negative demonstration. For intuitively reading displacement.

22, 11 are provided with nulling switch 42 and 47, are provided with nulling switch 34 at display 9, and their function is equal to. For convenience of user's use habit, alignment device also is provided with the yard and meter turn circuit, and the displacement of demonstration can be expired People's instructions for use in the different countries of foot and area. After paper 53 and PS plate 49 position corrections (contraposition) are good, get final product In batches printing, during printing, on have the PS plate 49 of China ink to roll at paper 53 to get final product. During for colored offset printing, one Multicolour pattern need to be printed once respectively by several colors, and these several colors must be in fixing position, and it is right that Here it is The different colours of same pattern all need be calibrated the position of PS plate 49 and paper 53. Printing a colour name card needs polylith PS plate, Whenever change a PS plate and all need the contraposition adjustment, the utility model has solved the quantized value that contraposition is adjusted, and makes the contraposition adjustment namely Fast and easy simply again.
