Quick Start Guide - Printer G7 Check and GRACoL Targeting

This guide will follow a common best practice using the ChromaChecker CC84 control strip. When aligning printing devices, it is not enough to just be G7 compliant. You need to know and match a target which in this case is GRACoL. Keep in mind that Chromachecker supports any control strip, spot color placeholders, and industry-standard data files so use this guide to configure the entire process and your assigned coach will help with your initial roadmap based on your organization's specific needs. You will find that ChromaChecker is both simple to use and sophisticated Color Quality Control.

Introduction

Your Quality Control Program will report on the precision and accuracy of the presses by validating the print condition of the press during normal production. The tools provided will allow you to check the press before, after, and/or throughout the print run, depending on the job and presses being used. 

Since we understand that print environments are dynamic with multiple devices, instruments, and workflows -- the Quick Start instructions are intended to allow you to maintain normal production. Specific targets and reporting requirements are based on the visual representation of the output and tied directly to measurable results in the form of DeltaE and E-Factor (CRF 95th percentile). We also provide a check for G7 compliance, substrate, and overprints.

At first, do not change your production process for this reporting, instead, maintain the highest quality for your clients and report the results. Targets will be determined based on Best Practices for the type of print condition, workflow, and devices.

Specification for Control Strip

The CC84 target is in the Capture Inspector and can be downloaded in PDF format. The Color target has to be at least 80 patches, and the G7 Production patches need to be present: solid CMYK, 25, 50, 75% tints for CMYK, RGB overprints, 25, 19, 19, 0 and 50, 40, 40, 0 and 75, 66, 66, 0, and 100,100,100, 0 and Paperwhite 0, 0, 0, 0 

Note: ChromaChecker supports any Control Strip layout and virtually any measurement instrument.  The CC84 target is a streamlined format that is quickly scanned while providing all the patches required for an accurate E-Factor and can be used to iterate G7 Curves eliminating the need for dedicated press runs. This makes it an ideal control strip for an initial evaluation of your current environment.

CC84 3-Rows and CC84 Single-Row

ChromaChecker supports any control strip and also can easily create new control strips that include placeholders for spot color patches enabling the identification of named spot colors in the workflow. For printing presses that have predefined control strips, that control strip can be used as a starting point. That automated ingestion process can be complemented with a CC84 for more advanced quality control and the iteration of G7 curves without a dedicated press run. 

 

 

 

What you need to collect data: Data Collection Choices

 

The type of instrument will identify the best method for uploading data as part of a quality control check. These include Manual Upload, CC Capture, CC Uploader, and direct API interfaces.  ChromaChecker supports industry-standard files so you may be able to easily upload using your existing scanning method. Data files can be tested by manually uploading a file using Print Inspector.

  • This tutorial shows you how easy it is to measure color bars using Chromachecker Capture software. ChromaChecker supports all color bars, all presses, and all instruments making it the optimal system for color quality control checking, correction, and reporting.

  • The starter kit provides the target and white/black backing for ensuring the instrumentation is ISO compliant and the environment is within manufactures specifications. Also included in the kit is an E-Factor printed exercise for establishing an appropriate tolerance for acceptable color shift for your production environment.

  • This tutorial demonstrates how to configure ChromaChecker Uploader to use ChromaChecker Print Inspector for analysis

  • This tutorial covers the use of Chromachecker Capture to operate an x-Rite iSis spectrophotometer.

  • Chromachecker empowers the entire organization by communicating an Expectation Fator (E-Factor) reporting the consistency of the printing process.

  • This tutorial shows how to use a barcode to automatically select the print condition and printing device that was used to produce the output being read by the iSis spectrophotometer. This automates the process of a quality check to simply placing the leading edge of the output in the iSis instrument to start the identification of the file and scanning of the control strip.

  • This tutorial shows how to work with the Image Exercise to set color match expectations. E-Factor is used to evaluate process colors and the amount of color shift from one sample to another. This uses the Cumulative Relative Frequency of the 95th percentile Delta E.

  • ChromaChecker is the industry-first Color Conformance Platform
    which enables a printer to establish their own capabilities and customer
    expectations and assess if the output device can meet their expectations. It is
    compatible with virtually any software that a printer is already using at
    proof and press, so operators don’t have to change the way they work.

  • This tutorial shows you how easy it is to measure a control trip using a Techkon handheld instrument using ChromaChecker Capture. Using a CC84 target you can quickly scan a color control strip that can be used to iterate a G7 curve.
