NIST Traceable Calibration
Calibration and master metrology traceable to NIST (National Institute of Standards & Technology).
SpectroDens Highlights
Quick Measurement of Process and Spot Colors
Control your process, spot, Pantone® or other critical brand colors by measuring solid ink density, % dot area, CIE Lab, deltaE, and more.
Track Densities Across Sheet
Shows density variation across press sheet and provides specific ink key adjustments right on instrument display.
Best Color Match
InkCheck™ feature helps press operators minimize color differences (deltaE’s) by providing specific density adjustments to achieve best possible color matches.
Spot and Scan Measurement in Same Device
Switch from spot measurements to color bar scanning with the touch of a button. Scan up to 200 color patches; no guide required, 4 wheels keep straight alignment while scanning.
Achieve G7 Compliance
GrayGuide™ feature displays G7 pass/fail indication and specific C,M,Y density adjustments to obtain grayscale values according to G7 specification.
Scan Media Wedge for Quick Proof Verification
Scan control wedge in seconds to confirm proofs against 12647-7 and known datasets like GRACol, SWOP3, SWOP5, IFRA, UGRA/FOGRA, G7™, etc.
ISO Check in 3 Seconds
Quick method for verifying print-to-print and print-to-standard color quality with clear pass or fail indication and explanation.
Desktop Software Included
Create, edit, and manage color libraries, import/export color data, generate pass/fail QC reports, and manage instrument, all with SpectroConnect.
Tailored to Meet Your Needs
The SpectroDens is available in 3 different models to best meet your color measurement needs (model comparison below).
Additional Information

SpectroDENS has been evaluated and adopted by printing companies big and small with the highest standards for quality. Our customers include Bemis, Quad, RockTenn, Menasha, Heidelberg, RR Donnelly. Here are some examples of their comments:

“We use the Techkon SpectroDens here. Works great for us, includes measurement export, nice trending features and a lot of features built in to one device. The ink check feature is very user friendly as well.”

“You are absolutely right the Techkon SpectroDens is very rugged and reliable.”

“The Techkon SpectroDens has the better UI, superior ergonomics, measurement speed, and nice *free* software.”

“We have both and the Techkon is better designed all the way around. If for no other reason, you can set it directly on the patch you want to measure and take a reading.”

“We just bought 3 of the Techkon SpectroDens, all the bells and whistles. Love them, why we waited this long I have no idea. Easy to use and amazingly…a fully charged battery last more than 10 minutes and you can use them not plugged up to a power cord!! WOW!!  Great customer service too, they will actually call you back…

“It’s just amazingly fast. I use it to do G7 Gray Balance Optimizations and I can
either read the minispots in spot or scan mode.”

“I’m going to throw in my vote for Techkon to…amazing consistency, accuracy and very easy to use. The software they provided (Expresso) and some other newer innovations are great. Some of their most recent software even includes helpful troubleshooting tips (i.e. it detects consistent slur in your last unit, it will recommend tension adjustments that may be helpful; obviously on a web press). Nice little package.”

What size aperture is included with SpectroDens?
The SpectroDens comes with a 3mm aperture. A smaller 1.5mm aperture is available at an additional cost.

Is the SpectroDens a densitometer or a spectrophotometer?
Both. Measurement is spectral. The spectral data is converted into density or colorimetric information. The spectral measurement technology calculates not only density values for CMYK, but also exact data for the density of spot colors.

Are there different versions available?
Yes, there are three different performance packages: The Basic model with essential density functions, the Advanced version with extended density functions and colorimetry and the “all-options” flagship the Premium device.

Can the units be upgraded?
Yes, very easy via program upload with the USB connection to a PC.

Which TECHKON products are replaced by SpectroDens?
The former R410 and R410e devices are in functionality comparable to SpectroDens Basic. SpectroDens Advanced replaces the SD 620 and SpectroDens Premium the SP 820 and SP 830 products.

What is included in the package?
The measurement device, charging console with integrated white standard, device case, USB-cable, CD with software SpectroConnect, manual with ISO 9000 certificate.

Is PantoneLIVE Connectivity available with SpectroDens?
The “partner ecosystem” for PantoneLIVE includes several software solution providers for color quality control. Their products are licensed to access PantoneLIVE color libraries. Typically, measurement devices connect with the color QC software which in turn connects with PantoneLIVE. Examples of widely used print color quality applications that connect with PantoneLIVE are MeasureColor and HAVI ColorSentry. Both of these applications, among others, also connect with Techkon SpectroDENS. Any other software application can also be easily connected with Techkon devices. Read more.
