Dither type
This is displayed invariably when Print Mode is set to Angled Screen.
Screen
This becomes settable in an interlocking fashion with the foregoing Dither type item, and displays a dialog box
for defining a native PostScript screen.
Perform Color Correction
Checking this setting activates the color correction settings. If this setting is not checked, incoming jobs are
assumed to already have color correction.
ICC input profile
Input profiles are used to convert the image into a neutral color space. Once the image is in a neutral color
space, then the output profile is used to convert the image into the color space of the output device. To add an
ICC input profile from another source, click the Add button. Three types of ICC input profiles can be specified:
CMYK ICC input profile
The CMYK input profile defines all elements of a job that are in CMYK color mode. If your job is in the
RGB color mode, then you should leave the CMYK input profile set to the Generic setting. If your file
contains images in both the CMYK and the RGB mode, then the CMYK input profile will be applied to the
CMYK images and the RGB input profile will be applied to the RGB images. If your image is in the
CMYK color mode, then your file was previously separated for output to a specific output device.
Whenever possible, use the profile for the device to which the elements were separated, as the CMYK
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
