Definitions

  • the present invention relates to a method for calculating amounts of ink to be used and more particularly to a method for calculating and displaying amounts of ink to be used for printing out an image(s).
  • the amounts of inks used for the respective process colors making up an image to be printed are regularly proportional to the number of sheets to be printed. However, these amounts differ according to the printing system used, e.g., offset printing. gravure printing, screen printing, etc. Furthermore, even in the case of the same printing system, these amounts vary according to the thickness of the ink that is to be transferred, the shape of the pixels and the type of object on which printing is to he performed.
  • the object of the present invention is to provide a method for calculating amounts of ink to be used, wherein when an image(s) that is to be printed is displayed on a graphic display, and the printing system, type of output dots, type of object on which printing is to be performed, and types of inks to be used, etc., we designated, then the amount of inks that are to be used for the single or multiple process colors that represents and makes up the image(s) can be calculated and displayed on the graphic display.
  • the present invention provides a method for calculating amounts of ink to be used, which is characterized by the fact that the method is devised so that: images to be printed, which are assigned to printing plate surfaces, are displayed on a graphic display; pixels of respective colors constituting the process colors that make up the images to be printed are integrated so that the total surface areas of the respective colors are displayed; the thickness of the inks of the respective colors prior to transfer are input and displayed; coefficients which are determined by the number of screen lines and shape of the pixels, or pixel designating symbols which indirectly designate such coefficients, are input and displayed; ink transfer coefficients which are determined by the object on which printing is to be performed, or printed object designating symbols which indirectly designate such coefficients, are input and displayed; the specific gravity values of the inks corresponding to the types of inks are input and displayed; and the number of sheets to be printed is input and displayed, and when an execution command is given, respective numerical values are multiplied for each color of the process colors, and the amounts of the inks of the respective colors that are

  • the process color confirmation button 4m in the ink amount calculating window 4 is clicked, so that all of the process colors and color names making up the image to be printed 3 are displayed in a row in the respective display columns of the first display box 4a in the window 4. If necessary, the respective display columns of the first display box 4a can be increased or decreased. In cases where the display columns are insufficient and the total number of process colors making up the image to be printed 3 is greater than the number of display column the display insufficiency is indicated by a v marking in the second display box 4b.
  • the third display box 4c in the window 4 is clicked, and gravure printing, offset printing or screen printing is selected (Figure 1 shows that gravure printing (G.P.) is selected) from the pop-up menu (not shown in Figure 1); and this selected printing type is displayed.
  • Figure 1 shows that gravure printing (G.P.) is selected
  • this selected printing type is displayed.
  • the third dialog box 4c is double-clicked, a dialog box which allows setting of the printing system and its coefficients appears, so that the characters for "flexo printing" for instance, can be input.
  • the fourth box 4d in the window 4 is clicked, and the desired material is selected from objects to be printed, such as P.P., C.A., O.P., high-quality paper, paper board and cardboard, etc., that are displayed on the pop-up menu (not shown in Figure 1) that appears. Consequently, the box display shows the name of the material selected.
  • coefficients corresponding to the material name and printing system are set in the program used to calculate the amounts of ink of the respective process colors that are to be used.
  • the fourth dialog box 4d is double-clicked, a dialog box which allows the setting of material names and their coefficients appears.
  • coefficients corresponding to the types of objects to be printed are added as calculation elements in the program used to calculate the amounts of ink to be used is that the percentage of ink adhering to the surface of the printing plate that is transferred to the object to be printed varies according to the type of the object to be printed.
  • the desired dot shape names are selected from the dot shape names that are displayed in the pop-up menu (not shown in Figure 1) that appears when the fifth dialog box 4e is clicked.
  • the box display shows the selected dot shape names; and in this case, coefficients corresponding to the dot shape names are set in the program. used to calculate the amounts of ink of the respective process colors that are to be used.
  • the coefficients corresponding to the dot shape names are classified according to combinations of the number of screen lines per inch with round dots, diamond-shape dots, hexagonal dots and free-flow cell dots, etc., and are expressed as fractions indicating proportions relative to solid-color printing.
  • the area obtained by integrating the pixels of the process colors of the image to be printed 3 that is displayed in the printed-image display window 2 is the area for a case corresponding to solid-color printing in which 100% of the surface of the printing plate is wet with ink; and this area includes portions corresponding to the screen lines, i. e., an area corresponding to portions in which the surface of the printing plate is not wet with ink; accordingly, if the amounts of ink to be used are calculated including such an area corresponding to portions of the printing plate surface not wet with ink, the amounts of ink used will be excessive. For this reason, the area of the printing plate surface not wet with ink is excluded so that accurate calculations can be performed.
  • the fifth display box 4e is double-clicked, a dialog box which allows the setting of dot shape names and their coefficients appears.
  • the content of the pop-up menu (not shown) that appears when the fifth display box 4e is clicked is associated with the gravure printing, offset printing or screen printing that is selected and displayed in the third display box 4c; and if the characters "gravure printing", for example, are selected and displayed in the third display box 4c, the dot shape names and corresponding coefficients used in gravure printing are displayed as a list, while the dot shape names and corresponding coefficients used 'm screen printing are not displayed as a list.
  • the coefficients corresponding to the printing system should be added in the program used to calculate the amounts of ink of the respective process colors that are to be used, in accordance with the printing system selected, i.e., gravure printing, offset printing or screen printing.
  • the specification of these coefficients is achieved by adding the coefficients corresponding to the dot shapes and the respective thickness of ink accumulating on the surface of the printing plate, as calculation elements in the program used to calculate the amounts of ink of the respective process colors that are to be used.
  • a desired ink name is selected from the names of ink types such as water-based ink, oil-based ink and UV ink, etc., that are displayed in the pop-up menu (not shown) that appears when the sixth box 4f of the window 4 is clicked.
  • the box display shows the selected ink name.
  • coefficients corresponding to the ink names are set m the program used to calculate the amounts of ink of the respective process colors that are to be used.
  • coefficients corresponding to the types of inks are added as calculation elements in the program used to calculate the amounts of ink used are as follows: the specific gravity values of the inks used must be multiplied, these specific gravity values are different for different ink types, and the viscosity and transfer characteristics differ according to the type of ink, so that the amount of ink transferred to the object to be printed from the surface of the printing plate differs.
  • the thickness values of the ink layers prior to the transfer of the respective colors are input and displayed in the respective display columns of the seventh display box 4g in the same window 4.
  • These numerical values refer to the thickness of the ink adhering to the surface of the printing plate and are not the thickness values of the ink layers following transfer of the ink to the object to be printed and evaporation of the solvent.
