RGB Separation Output/Simulation 1-4 GA-1120 Color Management GA-1120 color print option What it does Determines which CMYK color space your original RGB data will be separated into—CMYK for the copier (Output) or CMYK for a specified simulation (Simulation) (see page 1-8). It is important to note that when RGB Separation is set to Simulation, RGB colors are affected by CMYK Simulation Profile and CMYK Simulation Method. CMYK Simulation Profile Adjusts CMYK color data to simulate an offset press standard or a custom color gamut defined at your site. Choosing None bypasses simulation (see page 1-9). CMYK Simulation Method Quick/Full (Source GCR)/Full (Output GCR) (Default in Setup or ColorWise Pro Tools) NOTE: Some of the Simulation settings have slightly different names depending on the model of copier. Quick simulation applies one-dimensional transfer curves that adjust output density only. The Full simulations apply colorimetric transformations that adjust hue as well as output density (see page 1-10). Output Profile The output profile is applied to all data in the print job (see page 1-11). User-defined output profiles can be downloaded to the GA-1120 using ColorWise Pro Tools (see Chapter 3). Pure Black Text/Graphics On/Off (Default in Setup) Black Overprint On/Off (Default in Setup) Black Overprint Style Text/Text & Graphics Spot Color Matching On/Off (Default in Setup or ColorWise Pro Tools) The On setting optimizes the quality of black text and line art output. (see page 1-11). The On setting overprints black text and text/graphics placed on colored backgrounds. Overprinting colored backgrounds eliminates white gaps and reduces halo effects or misregistration of colors. The On setting automatically activates the Pure Black Text/Graphics option (see page 1-11). Specifies whether black overprinting should apply to text only or to both text and graphics. For this option to take effect, the Black Overprint option must be set to On (see page 1-13). The On setting enables GA-1120-defined matching of spot colors to their best CMYK equivalents. Off instructs the GA-1120 to match color output to a CMYK combination specified by the source application for the document (see page 1-13).
1-5 Managing color on the GA-1120 GA-1120 color print option What it does Sharpness +4 Sharpest/+3/+2/+1/0 Normal/-1/-2/-3 /-4 Softest/None Black Detection On/Off Toner Reduction On/Off Halftone Auto/Detail/Smooth This option enhances the sharpness or reduces jagged edges. To increase the sharpness, for printing image data such as phtographic, select one of the positive number settings. To print text or bitmap graphics, select None. If your job consists of black-only text pages combined with a signi cant number of color pages, set this option to Off. This option minimizes the amount of toner used on a printed job. For more information, see page 1-14. This option specifies how to simulate a halftone screen for your job. If you choose Auto, the appropriate screen is automatically selected, depending on the image data. If you choose Detail, all objects are printed with high resolution and a less jagged halftone screen. If you choose Smooth, all objects are printed using a smooth and stable halftone screen. Detailed explanations of how these and other settings affect your print jobs are provided in subsequent sections of this chapter. Rendering styles The Rendering Style option specifies a CRD for color conversions. You can modify the Rendering Style option to control the appearance of images, such as prints from office applications or RGB photographs from Adobe Photoshop. The GA-1120 lets you
