Paper Profile Configuring a Paper Profile is a fundamental part of calibrating a printer for optimum colour output. The profile is assigned to a Media and matches paper and ink characteristics to the output driver, resolution, colourspace and custom settings of the Media. The user interface for Paper Profile comprises of a toolbar containing options and functions to assist in creating the profile; and a tabbed panel where the printer’s dot sizes (Density Patches), Ink Limits and if appropriate, ink Separation Control are configured. Toolbar Options • Measure Patches – Use this to measure a printed density chart using a supported instrument. After selecting, choose an online device and desired density standard from the dropdown menus. Consult the instrument manual for supported types. When the device is ready, the measuring window appears. If instructed, calibrate the instrument and begin. • Change Media – Change the Media currently assigned to the Paper Profile. • Print Density Chart – Prints a density chart containing the patches currently turned on. Where patches are turned off, there will be a space on the output print. • Print Density Chart (All patches) – Prints a density chart containing all patches, irrespective of their on/off state. • Prink Inklimit Chart – Prints an ink density chart containing all enabled limits as one job to the selected Media and Pagesetup. • Print Inklimit Chart (Separate Jobs) – Prints an ink density chart for each enabled ink limit colour combination as a separate job, using the Media and Pagesetup selected. • Configure Inklimit Chart – Configures the combinations of inks to be tested for ink limits. Select which colours will be printed, the start and end ink percentage points and step increments. Note: If a combination is selected but insufficient patches to fill the row, an empty chart will be printed. For example, selecting to print 3 ink limit and 2 colours are selected, only the chart border will be printed. • Preview Graph – Show a graph of the patches currently turned on. See the Graph section for more information. • Sift and Sort – Enable or disable to option to Sift and Sort the patches in the Paper Profile. • Reorder Inks – Change the order of the inks in the paper profile to match the order used in the ICC profile. Often used for N-­‐Colour profiles. A list of ink channels will appear. Highlight and move using the up and down arrows, or drag and drop inks to the required position. • Upgrade – Upgrades a legacy (pre-­‐version 5) paper profile to the latest version. Density Patches This area shows the patches making up the Paper profile. Each patch represents a dot size or combination of dots available to the printer being profiled. The number of ink channels shown and the number of patches shown for each channel will vary, depending on whether the printer has variable dot capability; if it has light inks; and if the light inks are configured to be treated as separate or combined channels. These options are selected in the Output and Custom Settings of the Media chosen when creating the Paper Profile. Before densities have been measured, all patches will be turned on and will have default density values. These densities are updated with the data input from the Measure Patches option. •
•
Patches can be turned on or off by clicking the upper half of the patch. Clicking the lower half of the patch allows for manual entry of density values for that patch number. For colours that have visual and colour densities, select the letter to enter a value for – D for Density or V for Visual. When entering values manually, ensure the patch sort order is set to Patch Number. Note: If patches are measured in Lab mode, each will display an L value, rather than density values.
