% FrameMaker users specify the proper paper size for each print job in the % "Print" dialog's "Printer Paper Size" "Width" and "Height~ fields. If the % printer that the PS file is sent to does not support the requested paper % size, or if there is no paper tray of the proper size currently installed, % then the job will not be printed. The following flag, if set to true, will % cause the job to print on the default paper in such cases. /FMAllowPaperSizeMismatch false def
%
% Frame products normally print colors as their true color on a color printer % or as shades of gray, based on luminance, on a black-and white printer. The % following flag, if set to true, forces all non-white colors to print as pure % black. This has no effect on bitmap images. /FMPrintAllColorsAsBlack false def
%
% Frame products can either set their own line screens or use a printer's % default settings. Three flags below control this separately for no % separations, spot separations and process separations. If a flag % is true, then the default printer settings will not be changed. If it is % false, Frame products will use their own settings from a table based on % the printer's resolution.
% For any given PostScript printer resolution, Frame products have two sets of % screen angles and frequencies for printing process separations, which are % recomended by Adobe. The following variable chooses the higher frequencies % when set to true or the lower frequencies when set to false. This is only % effective if the appropriate FMUseDefault...SeparationScreen flag is false. /FMUseHighFrequencyScreens true def
%
% The following is a set of predefined optimal frequencies and angles for various % common dpi settings. This is taken from "Advances in Color Separation Using % PostScript Software Technology," from Adobe Systems (3/13/89 P.N. LPS 0043) % and corrolated with information which is in various PPD (4.0) files. %
% The "dpiranges" figure is the minimum dots per inch device resolution which % can support this setting. The "low" and "high" values are controlled by the % setting of the FMUseHighFrequencyScreens flag above. The "TDot" flags control % the use of the "Yellow Triple Dot" feature whereby the frequency id divided by % three, but the dot function is "trippled" giving a block of 3x3 dots per cell. %
% PatFreq is a compromise pattern frequency for ps Level 2 printers which is close % to the ideal WYSIWYG pattern frequency of 9 repetitions/inch but does not beat % (too badly) against the screen frequencies of any separations for that DPI. /dpiranges [ 2540 2400 1693 1270 1200 635 600 0 ] def
% PostScript Level 2 printers contain an "Accurate Screens" feature which can % improve process separation rendering at the expense of compute time. This % flag is ignored by PostScript Level 1 printers. /FMUseAcccurateScreens true def
%
% The following PostScript procedure defines the spot function that Frame % products will use for process separations. You may un-comment-out one of % the alternative functions below, or use your own. %
