Printing Density Measurement

Density measurement is a common product quality control method in the printing industry. It is the fastest, simplest, and most effective instrumental measurement method for inspecting and controlling the quality of printed matter. A printing spectrodensitometer is a key instrument for printing quality control, whose core function is to quantify the color and density parameters of printed matter by measuring the light absorption characteristics of printing inks. Printing Density Measurement is an essential step in offset printing to ensure consistent color reproduction.

Spectrodensitometer Application industry

Widely used in ink printing, film processing, textile printing and dyeing, plastic electronics and other industries accurate color measurement and quality control.

FAQs About  Spectrodensitometer

Light should be projected through the sample to measure haze, then assess the scattered light with an integrating sphere and sensors.  The haze percentage is ascertained by the scattering light to the total transmitted light.

a. Before installation, please Copy CQCS3 folder to your computer and don’t remove any files in CQCS3 folder.

b. Double-click the setup.exe to install CQCS3 software.

c. Then double-click Install.bat under the CQCS3USB_Driver file to install the driver.

d. Detailed installation information please read the "Installing Software" under CQCS3 User manual.doc.

 Color is measured using devices such as colorimeters, spectrophotometers, and spectroradiometers. Colorimeters are easier and good for simple color quality tests. Whereas spectrophotometers yield detailed spectral information. Hence, suitable for laboratories and industries.

Zero calibration of a hazemeter is a critical pre-measurement procedure to ensure the instrument’s accuracy by resetting its baseline to "zero" when no haze or light attenuation is present.

  1. Align the hazemeter’s measurement window with air or a black background, ensuring no objects block the window.

  2. Press the hazemeter’s zero calibration button and wait for the instrument to complete automatic calibration. At this point, the instrument should display a zero haze value and a zero light transmittance value.

  3. Observe the instrument’s display to confirm the zero calibration result stabilizes near zero. If the zero calibration is inaccurate, repeat the above steps multiple times until the displayed haze and light transmittance values stabilize near zero.

Perform 0-degree calibration before testing, this eliminates inherent instrument drift, environmental interference, or residual signal errors, ensuring subsequent measurements of transparent/translucent samples (e.g., plastic films，pvc, glass, coating, displays and cosmetic packaging) are reliable. Correct for minor instrument deviations caused by long-term use, temperature changes, or power fluctuations.

a. It’s needed to perform manual calibration for NH300 when first starting.

b. In the subsequent starting, no need to perform manual calibration.

c. Suggestion: it’s best to perform manual calibration once a week or when NH300 measured data is not accurate.

 A gloss meter measures the amount of light reflected from a surface at a specific angle. It's commonly used to assess surface finishes such as paint, coatings, plastics, and paper for consistency, quality control, and visual appearance evaluation.
