1. Analyze the print for quality assurance in order to determine whether your new profile should pass or fail Things to check for include posterization lizarding effects turtling effects bleeding banding patterns introduced by process and any other abnormalities Also check the final print for saturation and overall color Keeping in mind that different substrates media will look different it is reasonable to ask Is this expected behavior for the media and resolution Step 11 Distribution optional If you intend to distribute profiles you must be in accordance with the copyright statement of your profiling software We recommend that you distribute your new Imaging Configurations using our automatic installer In order to work with the Wasatch installer you must gather all of the files associated with the new Imaging Configuration into a folder that is called configurations case sensitive We recommend you put your working configurations folder in a temporary location for gathering the files such as c temp configurations Go to c wwrip configurations and find the folder with the name of the Taga Joes printer model used in your profile Illustration 11a There are separate a n al pee folders for each of that printer s installed Imaging Configurations within Booe the printer folder Illustration 11b are iar a For distribution you need your new profile to be in a folder named an as et pr2. etc When you have completed your settings click OK Modified 05 07 09 NOTE It is extremely important that all printer settings halftone settings inks media print modes and other factors that affect the print condition be set prior to beginning the linearization process DO NOT CHANGE THESE SETTINGS AT ALL DURING THE PROFILING PROCESS Illustration 2a Color Transforms screen Back on the Imaging Configuration screen click the Edit Info button and create a text file to record the properties you selected as part of your configuration This is helpful if you plan to distribute your final IC and is a good place to keep track of your notes as you build your IC When you click Edit Info your default text editor will open for you to enter notes When you re done select Save from the File menu and your info txt file will be linked to the Imaging Configuration name you select This information will be available to anyone who clicks on the Info button later You can also edit this file at any time After saving exit the text editor and you will be returned to the Imaging Configuration screen Step 2 Color Transforms Configuration Click on the Color Transforms button to launch the Color Transforms screen Illustration 2a This is your master color flowchart screen You will notice that all color data is cleared and set to none or default as a result of setting IC to none In the lower rig

4. TECHNICAL BULLETIN KO Getting Started A Note Before You Start Always calibrate your printer before profiling Follow the steps outlined in the printers user manual for printer calibration In this case calibration refers to the setup processes performed on the printer and are specific to that printer model it s not the same as the SoftRIP calibration described below Calibration processes include media feed calibration bi directional calibration head height media thickness head speed and any other calibrations prescribed by the printer manufacturer These settings should remain constant during profiling All calibrations should be redone after loading any new substrate material In short the printer should be in its optimal operating condition Sarharps Prisi iiaa kj Pa iae F pege TEU PF Cree Pape CL E pee cong Larguier T x z Lara Illustration 1a Setup screen Conte ali am Illustration 1b Imaging Configuration screen This document will teach you how to create ICC profiles using a combination of Wasatch SoftRIP and a third party color profiling software package such as ColorBlind Monaco ProfileMaker etc We recommend that you allocate a minimum of 20 feet of media to produce each profile Although this document provides a detailed discussion of how to create profiles using SoftRIP you will also need to refer to your profile making software manual for intermediate steps where note
