[. . . ] (These percentages refer to the size of the CMYK halftone dots. ) The curve you selected appears, and points along the curve are marked so you can adjust them. A curve with this shape makes a color appear darker by adding density in the midtones. A curve with this shape increases contrast. NOTE: You should adjust points in this way only after you have entered the Dot Gain and Brightness values. 4 9. 10. 4-16 ColorWise Pro Tools For greater precision, you can key in percentages in the Input and Output boxes or use the arrow keys on the keyboard to adjust the curve. To use the arrow keys, you must first click on the curve to establish an anchor point that serves as a reference. For an output profile, you can set maximum densities of the C, M, Y, and K channels. You can enter the maximum densities, called D-Max values, of individual colors for profiles that support density settings. D-Max settings are not available when editing Simulation profiles in Master mode. When you are finished, click Save and enter a name for the new profile. The new custom profile is saved to the Fiery 3850C with the new name. If you edit one of the press standard targets (for example, SWOP-Coated, DIC, or Euroscale), you may want to include the original name as part of the new target name (for example, DIC-new) to help you remember the source of the new target. NOTE: Preset default profiles are locked and must be saved with a new name. Custom profiles must be linked to one of the 10 predefined custom profile names (Simulation-1 through Simulation-10 for Simulation or Output-1 through Output-10 for Output) in order to be accessible from the printer driver. You can create as many custom profiles as you want, but a maximum of 10 are available from the printer driver at any one time. See "Defining profiles" on page 4-8 for information on linking custom profiles to the predefined custom profile names. If you set a custom profile as the default, you can access it from the printer driver without linking it to one of the predefined custom names. Select "Printer's default" from the printer driver. Undoing simulation edits You can undo the changes you made to simulations (master and linked) in these ways: · If you have not yet saved your edits, click Done on the Color Editor menu bar, and do not save the changes. · If you saved your edits under a new simulation name and want to delete all edits to the simulation, see page 4-7. · If you saved your edits under a new simulation name and want to undo the edits to one or more linked simulation, use the following procedure. 4 TO 1. 3. 4-17 Color Editor UNDO EDITS MADE TO A CUSTOM LINKED SIMULATION Launch ColorWise Pro Tools and click either Color Editor or Profile Manager. Choose Simulation from the View pop-up menu, choose the simulation for which you want to undo edits, and click Select (Color Editor) or Edit (Profile Manager). Choose the output profile with which your unwanted edits are linked from the Link with menu. 4. Click Revert to Master. NOTE: Revert to Master makes the curves for one or more linked simulations match the last saved master simulation. If you have edited and saved changes to a master simulation, your linked simulations will revert to the changed master, not the original. 4 5. 6. 4-18 ColorWise Pro Tools Indicate whether you want to revert the currently selected linked simulation only, or revert all links of this simulation profile, and click OK. If you choose "For all Edit Modes and all Profile Links, " a warning dialog box appears. Click OK. The curves for the linked simulation(s) now match the last saved master simulation exactly. Checking edited profiles You can view a printed sample of a profile before you save it to the Fiery 3850C. To do so, print one of the following: · Comparison Page provided with ColorWise Pro Tools, which shows a comparison of images and colored patches with and without edits · User-defined CALIB. PS in the Hold Queue You can create a custom comparison page and save it as a PostScript or Encapsulated PostScript (EPS) file called CALIB. PS and then print the file to the Hold Queue of the Fiery 3850C from your application or download it to the Hold Queue with Fiery Downloader (see page 3-35). 4 TO 1. 2. 4-19 Color Setup CHECK A PROFILE Click Test Print from the Color Editor window. Select a page to print, specify the paper size and input tray (Comparison Page only), and click Print. For Comparison Page, specify the paper size (LTR/A4 or 11 x 17/A3) in the Paper Size pop-up menu. In the Input Tray pop-up menu, specify the paper source. Color Setup Color Setup is used to set the default ColorWise settings for the Fiery 3850C. To access Color Setup, click its icon in the ColorWise Pro Tools main window. Setting default ColorWise options Color Setup allows you to configure the default color management settings for the Fiery 3850C. [. . . ] The term is a combination of the words "picture" and "element. " PostScript Software applications commonly used for business purposes, including presentation applications, spreadsheets, and word processing programs. offset lithography Printing in which ink is transferred from printing plates to a rubber blanket and then from the blanket to paper. output profile A device-independent page description language developed by Adobe, which is used to print and display pictures and text. PostScript 3 includes many enhancements to older versions of PostScript, including improved image quality and color with Enhanced Image Technology, faster performance with Advanced Page Processing, and ease of use and setup with NetWorks System. PPD (PostScript Printer Description file) The output profile describes the color characteristics of a printing device. It consists of both a profile for your printer and a calibration target that defines the expected density response of the printer. phosphor A file containing information about a particular PostScript print device's capabilities and restrictions. The information in the PPD is presented via the printer driver. prepress proof Material used in making computer monitors; phosphors glow and emit red, green, and blue light when struck by an electron beam, thus creating an image. A print made from a set of film separations or other file to simulate the results of printing. [. . . ]
