3nh TS1050 Spectrodensitometer (Professional Edition) is a high-precision quality control device designed for medium-to-large printing enterprises, professional quality inspection agencies, and packaging groups. Utilizing planar grating spectrophotometric technology and equipped with a dual-array 40-group silicon photodiode sensor, it achieves a density repeatability of 0.001D and supports a density scanning function to comprehensively analyze print quality distribution. With guaranteed first-grade metrology certification, the TS1050 ensures measurement data authority and traceability, catering to diverse, high-precision, and large-data volume testing needs. The core advantage of TS1050 lies in being ‘Professional, Comprehensive, Precise, and Efficient’: featuring 5 interchangeable measurement apertures to cover full-scenario requirements from large color blocks to fine graphics, an inter-instrument agreement of 0.20 to ensure data consistency across multiple machines, and a massive 20,000-record storage capacity for batch inspection data traceability. Whether for daily production quality control, multi-machine unified management, or large-batch finished product inspection, TS1050 delivers a professional, accurate, and efficient measurement solution.
Powered by planar grating spectrophotometry and a dual-array 40-group silicon photodiode sensor:
Density Repeatability: ≤ 0.001D
Colorimetric Repeatability: ΔE*ab ≤ 0.02 (Based on average of 30 white plate measurements, except M3)
Inter-Instrument Agreement: ΔE*ab ≤ 0.20 For enterprises operating multiple devices across various workshops, it ensures highly consistent measurement data across machines, unifying quality control standards while lowering cross-department communication costs and quality risks.

A single measurement takes only about 1 second, substantially accelerating batch testing, minimizing worker waiting time, and enhancing production line inspection throughput.

Equipped with 5 measurement apertures: Φ11mm, Φ10mm, Φ6mm, Φ5mm, and Φ3mm. Users can flexibly select according to sample size and measurement needs. From large solid color patches to medium fine patterns, one device covers full measurement scenarios without frequent device switching, drastically improving testing efficiency.

Supports continuous multi-point density scanning on printed materials to generate density distribution curves, visually demonstrating full-page printing uniformity. Scanning data quickly pinpoints local density deviations and uneven ink layer thickness, assisting technicians in diagnosing press status, accelerating color matching/calibration, and elevating overall print quality.

Guaranteed first-grade metrology compliance provides high authority and traceability, satisfying strict requirements for ISO quality system certification, customer audits, and third-party testing. It helps enterprises pass high-end client factory audits and gain competitive market advantages.

Supports real-time multi-platform synchronization across Android, iOS, Windows, WeChat Mini-Program, and HarmonyOS. Enables cloud color library searching, personal color database creation, enterprise-level color library sharing, auto-generation of professional analytical reports, and one-click export of quality inspection documentation.

Supports Netmetric network calibration, enabling accumulated measurement deviations caused by long-term instrument use to be corrected remotely over the network. It also allows systematic calibration and alignment of all instruments within an organization and across its supply chain, significantly reducing inter-instrument measurement variation. For group enterprises with multiple factories and production lines, Netmetric enables unified quality standards and centralized management across sites, substantially reducing communication costs and quality risks associated with cross-factory collaboration.

FAQs About TS1050 Spectrodensitometer
A colorimeter is used to measure absorbance at selected wavelengths with the help of filters, which is suitable for rapid comparison of colors. A more advanced spectrophotometer has a monochromator. It can measure a larger range of the spectrum of light and is more accurate. You can also get detailed color data at visible and non-visible wavelengths.

There are many factors that can influence accuracy such as surface roughness, temperature, substrate material, and calibration settings. For ferrous metals, external magnetic fields can also distort measurements. Proper calibration and preparation will help reduce the impact of these factors.
Gloss is the general reflectivity of a surface, which encompasses a variety of degrees. One particular type of finish is high gloss, which has the maximum shine and reflectance. It increases the richness but emphasizes flaws as compared to satin or matte.
Colors look different under various lights mainly because of metamerism—a phenomenon where two colors that match under one light source fail to match under another, caused by differences in the spectral composition of light.

Different lighting varies the color perception of objects. Warm light, like that from incandescent bulbs, tends to make colors more yellow, while daylight presents a bluish tint. Our color vision system plays a compensating role using a mechanism called color constancy.
Every light source emits light with a unique "spectral fingerprint" (i.e., the range and intensity of wavelengths it contains). This directly affects how an object’s surface reflects light and how our eyes perceive its color.
a. It’s needed to perform manual calibration for NH310 when first starting.
b. In the subsequent starting, NH310 will perform auto calibration at startup. No need to perform manual calibration.
c. Suggestion: it’s best to perform manual calibration once a week or when NH310 measured data is not accurate.
