This tutorial shows the simple operation of the i1i0 table using Chromachecker Capture software. The control strip consists of 18 spot colors and the G7 patches to iterate a G7 curve directly out of Capture. This creates a simple and automated process for operators to perform a quality check on G7, process colors and spot colors.
How to save a PDF file for use in the Named Color workflow with ChromaChecker. ChromaChecker is able to create custom lookup tables using device ICC output profiles. These tables are used to convert LAB values for each individual press to achieve the best match for critical spot color workflows.
The Spot Color Exercise is an interactive way to communicate how Spot Colors will print and determine the Delta E difference that is acceptable. The exercise is an instruction and a practical tool for designers, print buyers, and sales for communicating color.
This tutorial shows how Chromachecker Capture scans control strips that include spot colors as part of your overall color quality control program.
