Standardization by ChromaChecker™

ChromaChecker’s method for Qualification is critical to ensure your color components are operating consistently and in a standardized way to ensure accuracy in the process. 

 

 

Stage 1–Using ChromaChecker™ – Qualification Module


Before purchasing a printing device, or taking over the responsibility for a printing device, you should learn about it’s specific characteristics in terms of the stability and repeatability as well as it's level of accuracy to a given printing aim condition (such as SWOP (G7) or GRACoL).
If the device is not printing properly, you need to discover this and fix the issue. For example, in offset printing, a mechanical problem can be observed as slurring or doubling causing variation in tint reproduction. In inkjet printing, clogged nozzles or worn out heads can produce banding are other undesirable artifacts. Most problems are well known and there are maintenance procedures to fix them. There are problems caused by the substrate and other consumables. An unstable environment can have the influence on the process too.
Hundreds of parameters can contribute to many problems. 

 

Check if the Printing Devices are stable and repeatable – Variation Inspector

If you find problems you may want to use additional pre-qualifying tools in order to fix mechanical issues: Slurring-Doubling Tool, Nip Control Tool

Qualifying your output devices consistency
Variation Inspector – Analyzes the precision of any print process and can be used to determine intra-page (spatial) uniformity of a print, inter-page consistency (multiple pages in a run) and inter-job consistency (job to job, day to day) performance. Can be used to determine if more calibration or maintenance of consumables is required to keep the device within its expectations (E-Factor™) for repeatability.   

 

Check if the printing devices are accurate to your production printing aim points (G7)
- Print Inspector

You may use our tools to either change current printing condition or to find new Reference Print Condition that better describe your case. 

Qualifying your output devices accuracy

Print Inspector- Analyzes and monitors an output devices ability to match a given Reference Print Condition,
which is defined as Accuracy. Data can be used to determine the cause for a lack of accuracy.

Qualify these devices with ChromaChecker Inspectors:

  • Instrumentation 
  • Substrates
  • Lighting
  • Environment Condition
  • Setters
  • Profile Inspector 

This step will reduce potential errors before you start printing - to avoid waste of time and money.

  

More Details:

Qualifying Instrumentation

Instrument Inspector

—  Analyzes and monitors Color measurement devices to ensure the instrument(s)
are measuring consistently and accurately to one another, throughout the entire supply chain.
If an instrument is dropped, the performance of the instrument can be assessed in minutes
to determine if the instrument is still suitable for its desired task, or if it needs to be sent
back to the factory for service. E-Factor is determined for a device against itself over time (consistency)
or any instrument can be compared to any other instrument to determine
the variation caused by different measurement devices.

 

Qualifying Lighting

Lighting Inspector

— Analyzes and monitors Lighting Conditions - when a visual judgment is
determining a factor for adjusting the way in which the output device creates color, it is imperative
that the Lighting is consistent and accurate. Lighting can be compared to itself over time,
and compared to  the D50 standard, and can be compared to other Lighting environments
through the plant or supply chain to quantify if the lighting is causing the failure
of meeting the desired expectations (E-Factor).

 

Qualifying your Environment 

Environmental Inspector

— Monitors critical ambient conditions including temperature and humidity.
Can provide notifications and warnings should these attributes exceed the defined limits for operations.
Can be superimposed on the graphs showing the print process performance to tie together the factor
that temperature and humidity can greatly affect the performance of some output devices.

 

Qualifying your Platesetters and Imagesetters

Platesetter Inspector

— Used to monitor that proper linearization (even if is made in one step with dot gain correction)
is in place to ensure that Platesetter or Filmsetter is in a repeatable condition

 

Qualifying your Substrates

Substrate Inspector

—  Analyzes and monitors substrates as the most critical medium in the process  (5th color in 4 color printing), that has a huge impact on the printing condition.

 

Qualifying your ICC Profiles and your Targeted Reference Conditions

ICC Profile Inspector

— Analyzes the precision of an ICC Profile versus the data that was measured to create it.

 

 

 

How to evaluate printing device performance?

Stage 2- Monitoring/Tracking Stage

ChromaChecker Tracking Module- will monitor your production process and alert you to problems before there are too much waste and physical losses. Process monitoring for all color components lighting, instrumentation, device performance, plate setter, environment. 

ChromaChecker Variation and Print Inspector can automatically collect data from numerous print processes, or the user can upload data to the Inspector directly. Variation Inspector is a tool which measures the variation in a printing process. Variations reflect device repeatability and stability and can be due to many issues including operator performance. The key is to establish optimal parameters. Print Inspector measures the accuracy and will show how accurate the output device is performing.

Generally speaking, we can expect that printing devices are able to print in a similar way all the time.
Some printing technologies are sensitive to various parameters e.g. operator use, mechanical settings,
adjustments or properly done maintenance procedures, ambient condition temperature or humidity,
quality of consumables such substrates, inks or toners or many others. Every output device has different parameters and variables that greatly affect results. Variation Inspector provides real-time information on a device's performance and allows for the entering of “events” which can be any task applied to the process and you will instantly see if this “event” improved the result or had no effect on the printed process.
This allows you to quickly learn how to improve your process.

 

 

Stage 3 – Correction Stage

ChromaChecker Process Control Module can be used to proactively troubleshoot your process and make a suggestion or physical changes to your process to get your devices back on  the given standard the you are matching to. This module allows you to update your plate curves or TRC’s for digital devices to keep them printing correctly. Can be used to troubleshoot problems that you encounter while monitoring the process.
