Press release from the issuing company
Danvers, MA——Techkon USA – a leader in color measurement instruments and color management software for commercial printers and materials manufacturers – introduces the latest functions of their SpectroDensTM 4 spectrodensitometer. 4th in the line of a series of continuously evolving all-in-one (combined densitometer and spectrophotometer) handheld color measurement instruments from Techkon, SpectroDens 4’s newest features include OBA-CheckTM and visual opacity measurement functions. These functions join a list of capabilities that also include: measuring solid ink density, CIE LAB density, printing curves, and dot areas; checking G7 conformance; and performing ink checks, or best color matches. OBA stands for Optical Brightening Agents, which are used frequently in paper production. OBAs have a significant effect not only on how one perceives paper under different illuminants, but also on the results of putting ink down during the printing process. SpectroDens 4’s measurement function, OBA-Check, provides precise information about the intensity of the optical brightening agents used and the shade of the paper (often referred to as “the 5th color”). Measuring for visual opacity is a need that’s become more prevalent, as it is now referenced in an ISO standard for graphic technology. ISO 23498:2020 is a specific visual opacity guideline regarding a measurement characteristic of printed white ink. SpectroDens 4 is the first color measurement instrument to offer a unique visual opacity of printed white ink measurement function. It allows a user to measure and monitor opaque white ink's “hiding power”, as it is commonly referred to. Opaque white ink is widely used in flexographic and offset packaging printing. Measuring it requires that (4) unique measurements are made of the ink drawdown on a black and white contrast card. These (4) measurements are interpolated by the SpectroDens 4 spectrodensitometer and provide the user with the white ink's ability to minimize the factor of the substrate material in the printing process. If this information is not available, press operators are often guessing incorrectly on color corrections because they’re not factoring in the white ink’s impact. This can lead to longer make ready times and unnecessarily wasted substrate materials and ink. Additional features of the SpectroDens 4 include:
SpectroDens 4 is calibrated to standards that are in accordance with the National Institute of Standards and Technology (NIST). It is available at (3) price points ranging from a basic model (primarily density-oriented measurement functions) which is $5,450, an advanced model for $7,300 (adds the ability to measure M0 through M3 conditions and delta E of CIE LAB, and conduct ink checks), and an $8,900 Premium model (conducts delta E on CIE LChab, and measures whiteness, OBA and visual opacity, automatically conducts an ISO check and pass/fail tolerances, creates a metamerism index, and more). Each comes with Techkon’s device utility software SpectroConnectTM. Optionally, customers can also tap into Techkon’s cloud-based color management software platform, ChromaQATM for additional features. ChromaQA allows for storing and sharing insightful job and color data across the enterprise for maximum production efficiency and corporate profitability. ChromaQA provides press operators deeper insight on ideal corrective actions to take during make ready and production, and quality managers the ability to centralize ink management and create powerful job reports and shift performance analysis. Also, included in ChromaQA is the ability to manage an entire fleet of SpectroDens devices and other Techkon color measurement instruments globally. Team leaders can ensure devices have been calibrated and recertified on a regular basis and are working properly no matter where they are located. To learn more about SpectroDens 4, visit: www.techkonusa.com/products-2/spectrodens4-densitometer/ The SpectroDens 4 and ChromaQA will also be available for evaluation and trial at Techkon USA’s demo center located in their booth at Labelexpo Americas 2022 (booth #5800) and Printing United (booth #N543).
