Step-by-Step
1) In an empty workspace and the desired calibration selected, click on the Color Chart icon, which is located in the Tools menu and also in the interface toolbar or on the sidebar. When working with spot color replacement, you can create variations from obtained spot color.
2) Select "Output profile color space" so that swatches are labeled with RGB values from the printer profile in use.
3) Select "Variation of one" and set your desired deviation percentage and the number of steps per channel. Each increase in the number of steps per channel will increase the total patch amount exponentially.
4) Set patch size and separation as per required, having in mind that RGB numbers will be located in the vertical separation area, at the bottom of each swatch.
5) Click on the color chip to edit the color reference. A color picker dialog will be opened.
a. If you want to select the color manually just pick it up or enter RGB values and click on Ok.
b. If you have a spectrophotometer and want to get the reference color from a sample:
1. Click on Measure. The measuring device configuration dialog will open.
2. Select your device and set Illumination and Observer according to the lighting conditions of the site where the printed chart will be observed. Set a number of samples different from 1 if what you need is an average of several measurements (up to 5).
3. Check "Use UV-cut filter" (M2 measurements) for optically brightened samples. Check "Emission measurement" for backlit samples.
4. When clicking on Ok you will be asked to calibrate the device if required by the application. Once the device is calibrated measurements can be started.
6) Once you have finished these settings just click ok and the color chart will show up on the workspace. Print it and select your best option.
