What is Closed-Loop Color Process Control for Offset, Flexo & Digital Presses and Why it’s Time to Retrofit

Periodic color monitoring and control of aim characteristics (color, density, TVI, G7, etc.) of an offset, flexo,or digital press is extremely important for ensuring accurate and consistent color reproduction throughout the press run. These operations can either be accomplished manually, semi-automatically or automatically via color measurement hardware and color control software. Manual color control is a primitive method of quality control that uses a “trial and error” process—and it’s costing printers worldwide millions of dollars…

What is a SpectroDensitometer?

By: Bruce Leigh Myers, Ph.D. Color reflection densitometers have been used for many years in the graphic communications and printing industry and are likely the most widely adopted type of color measurement instrument for process control especially when dealing with four-color process (CMYK) printing. In the 1990’s, instruments began to be utilized that, while providing densitometric information, were referred to as “SpectroDensitometers.” This has led to confusion by some and has been regarded as hyperbolic…

5 Advantages of Using an Automatic Scanning Color Spectrophotometer

Automate your color control process An automatic scanning color spectrophotometer like the SpectroDrive is a perfect tool to aid in the task of automating your color control process. It is designed to scan entire press sheet color bars in a matter of seconds thus eliminating the need for manual measurements via a handheld device. These devices are fast, accurate, and can also scan color bars anywhere on the press sheet. Collect & distribute data The…

What are M0, M1, M2, M3 Measuring Mode Settings

In accordance with the ISO 13655 standard, the “M” series of measuring mode settings were defined in order to standardize illumination conditions where optical brightening agents are utilized in substrates. The following is designed as a quick reference chart of the 4 different measuring mode settings within the “M” series. M0 “Color measuring mode A” spectral luminance factor without polarization filter under a light source that simulates standard illuminant A (gas lamps or LEDs, 2856…

Choosing the Right Color QC Software Package

Brand managers and print providers can take control of their color quality process by implementing a Color QC software solution.  Color QC software solutions are an essential tool in the pressroom to communicate job color standards and tolerances, provide PASS/FAIL feedback for operators, offer recommendations to quickly achieve desired color targets, and provide reporting of job color metrics to internal and external stakeholders such as brand customers.  Press-side and on-press color quality solutions are available…

Optimizing Density for Non-Process Colors

When printing colors other than CMYK, many users understandably turn to colorimetric information (CIE LAB, Delta-E). Frequently overlooked, however, is the importance of using optimized density metrics for process control in the offset lithographic pressroom.  One such metric, available on many spectrodensitometers, is spectral density (sometimes called “density-by-wavelength” or “lambda density”). A brief illustration of how a densitometer “sees” color ensues, followed by an overview of spectral density. Consider looking at a printed cyan ink…

Have You Fallen Behind on Your Device Recertifications?

The device recertification process for a densitometer or spectrophtometer ensures that your device is functioning properly and meets our strict international standards.  We recommend it be evaluated every 12 months at a Techkon Service Center. This preventative maintenance is critical to keeping your equipment performing at optimum levels and will help avoid sudden and unexpected interruptions on the pressroom floor. Properly maintaining your equipment helps ensure the accuracy of your color measurements while also extending…

3 Reasons Offset Printers Need Automated Color Control

While color measurements can be taken by hand, calculated, and worked out to verify a ‘passing’ sheet, for most offset printers this is not practical. The time it takes, both to measure and to calculate all the required print attributes, is prohibitive. When printers ask about doing this, we advise that while it can be done, for most printers they will not be successful. Many brand customers care about a variety of attributes such as…

MYIRO-1: First Impressions of the Software

A few weeks ago I wrote a blog regarding my first impressions of the MYIRO-1 instrument and how it stands apart from the competition.  This week, I’d like share a few quick thoughts regarding the MYIRO-1 ICC color management software and how it has been built to support several specific use cases that complement an ICC profiling workflow very nicely. Ease of Use: Before we get into the features and functions of the software, I…

The Importance of Color Quality for Brand Owners

We invited Sonja Dearden, Print Production Manager at Lindt Chocolate, to a discussion on color quality for brand owners and developed this Question & Answer Guide to provide valuable insights on the importance of print standardization when managing color around the globe. QUESTION: Why do we need print standardization? ANSWER: An international company can have many different designers, pre-press agencies and print vendors around the globe working on their brand. If they all start from…

Beyond the Brand Requirements: Using On-Press QC for Efficiency

Screen from ChromaQA, Color Quality QC software, showing ink Delta E, as well as recommended adjustments to improve Delta E. For printers, being able to see if the print is good during makeready and production is important. Most press consoles do not have any easy way to see if a print is measuring to the print standard. Press consoles typically show metrics such as dot gain, density and even solid ink LAB values but they…

A Testimonial from Paul Sherfield

Me and my MYIRO :  I have been using my MYIRO-1 for nearly 10 months now as my main handheld, computer attached spectrophotometer. The instrument from Konica Minolta is clearly aimed as the first creditable competitor to well known market leading spectrophotometer in this area. Its build quality is good, a strong plastic body with a ‘lens cap’ that also serves as the calibration plate. The instruments technology is based on Konica Minolta’s FD-9 high-end…

Deployment of Press-Side Color QC Is Easier Than You Think

Good afternoon everybody and I sincerely hope you are all doing well during the COVID-19 crisis that we are all facing.
