Specifying the color rasterized image processor (RIP) on this server Important: You only need to do this step if you will be submitting color PostScript print jobs to your InfoPrint Color 130 Plus. The RIP generates the data stream that InfoPrint Manager sends to the printer. By default, InfoPrint Manager uses a RIP that produces monochrome (black and white) documents. Therefore, you must specify the color RIP from the ps2afp data stream transform before you send color documents to your InfoPrint Color 130 Plus. To make the necessary configuration changes and start the color RIP, use this procedure: 1. You first need to stop the ps2afpd daemon: a. Find the process id number: ps | grep ps2afp b. Stop the daemon: kill -9 2. Edit the ps2afpd.cfg daemon transform configuration file that is located in the /usr/lpp/psf/ps2afp/ directory on the AIX server using your editor of choice. 3. Change the ps_output_type value to FS45, as shown in this example: ps_output_type = FS45 # -a type of AFP image to generate 4. Save and close the file. 5. Start the daemon again: /usr/lpp/psf/bin/ps2afpd -C /usr/lpp/psf/ps2afp/ ps2afpd.cfg If you ever want to send monochrome print jobs to your InfoPrint Color 130 Plus, you can stop the color RIP and start the monochrome RIP by changing the ps_output_type value back to the default value of IO1_G4, as shown in this example: ps_output_type = IO1_G4 # -a type of AFP image to generate Changing the color rendering value While the InfoPrint Color 130 Plus produces vibrant full-color images, including images that contain gradients and shading, it is not able to reproduce every shade of every color. The color rendering intent value (color-rendering-intent attribute) determines what InfoPrint Manager does when it encounters a shade in a PostScript image that the InfoPrint Color 130 Plus cannot reproduce exactly. There are two possible values for color rendering intent: Relative When InfoPrint Manager encounters a color that InfoPrint Color 130 Plus cannot reproduce, it substitutes the closest color value that it can reproduce. Perceptual When InfoPrint Manager encounters a color that InfoPrint Color 130 Plus cannot reproduce, it adjusts all of the colors in the image so that they maintain their color relationships to each other. The result is an image that is pleasing to the eye, but that might not look exactly like the original image. The default value is Relative. Chapter 2.
