input profile. If you do not have the profile, try similar profiles or profiles for common ink sets (such as CMYK SWOP, or High End SWOP). If you are trying to match Pantone colors, it may also be appropriate to select High End SWOP as your CMYK input profile, because Pantone Process CMYK values were designed for output to the SWOP ink set.

RGB ICC input profile

The RGB ICC input profile defines the RGB source for all of your RGB files. An RGB input profile can be for either a monitor or a scanner. If you scanned your file directly to a folder, it is best to select your scanner calibration as the RGB input profile. If you have done any on- screen color correction, you should select your monitor as the RGB input profile. If you do not have a monitor profile, it is generally safe to select the Generic ICC input profile. The Generic profile assumes that you have a Trinitron monitor with a temperature of D65 and a gamma of 1.8. Selecting the correct RGB source will insure that the RGB data you see on-screen will be matched to the output printer.

Gray ICC input profile

The Gray ICC input profile defines the Grayscale source for all of your grayscale files. This may refer to either a grayscale scanner or a grayscale monitor.

ICC output profile

ICC output profile- Output profiles are created for the combination of ink and media, and resolution and dither type of your output device. When selecting a profile, be sure to select the profile that matches these criteria. For output devices that print at multiple resolutions, RIP Software provides profiles for each of those resolutions. Choosing a profile with the wrong resolution will severely effect the output. Profiles with different dither types will not greatly effect your output; however, they may cause slight shifts in color. To add an ICC output profile from another source, click the Add button. Click the Info button for information pertaining to the ICC output profile that has been chosen under Profile.

Bitmap/Vector Rending Intent

Rendering intent- before a file can be RIPed, its ICC profile must be selected so that the RGB color space of the file can be mapped or translated into to CMYK colorspace. How the colorspace gets mapped is determined by the color rendering intent that you select. The rendering intent selected in the Bitmap rendering field will be applied to bitmap images in your job file. The rendering intent selected in the Vector rendering intent field will be applied to vector images in your file. Choose from one of the following rendering intents:

Perceptual

This intent is best for photographic images. Colors outside of the output device's gamut are either clipped or compressed to fit the output device’s color space

Relative Colorimetric

This intent is best for images, such as logos, where the original image needs to match the output. Colors that fall outside of the output device's gamut are clipped. This method may reduce the total number of colors available. The white point of Relative Colorimetric is always zero.

Saturation

This intent is best for graphic images, such as vector art, where vivid colors are more important than true color matching. Colors outside of the output device's gamut are mapped to colors at the extent of the gamut's saturation. Color's that fall within the gamut of the output device are shifted closer to the gamut's saturation extent. This rendering intent may also be used to boost colors within a photographic image.

Absolute Colorimetric

This intent is similar to Relative Colorimetric, but has a different white point value. Absolute Colorimetric represents colors relative to a fixed white point value of D50. For example, the white of paper A will be simulated when printing on paper B. This intent is best for color proofing.
