The SpectroEye portfolio has a solution for every need and price point
SpectroEye LT: an affordable entry-level solution that delivers the primary functions required for process control at the press. SpectroEye LT supports all the densitometric functions from density to trapping, as well as the CIE L*a*b* function.
It is the ideal device to check CMYK prints according to ISO standards. SpectroEye LT can easily be upgraded to SpectroEye through the purchase of a software access code.
Also available in small aperture (SA) (see below for SA description)
SpectroEye: SpectroEye is ideal for customers who print CMYK and spot colors and who track systematic process control.
Also for use in QA and ink mixing. Measures standard control bars utilizing 4.5mm aperture.

SpectroEye SA: For customers who have smaller control elements, SpectroEye SA is equipped with an aperture of 3.2mm designed specifically for reading patches as small as 3.5mm. With the identical accuracy of SpectroEye, SpectroEye SA offers customers who work with smaller control elements the option for unparalleled quality control, representing an incredible increase in production power. SA also available for SpectroEye LT

The new spectral densitometer sd350

The ColorLite sd350 is a spectral densitometer designed for the high demands of the automotive industry.

It measures transmission density values of optical film in the printing and screen printing industry.
The high quality device is characterised by a number of features which are not available in other densitometers on the market.
From the integrating sphere light source to the high resolution spectrometer, the sd350 sets a new standard for measuring the quality of optical films.
Using high performance LED’s, with a life span of over 20 years, and a grating spectrometer we can ensure perfect stability over its life time.
Apart from a long life, this results in high accuracy which makes it possible to directly communicate absolute values.
A high dynamic range is guaranteed by a 2-channel system. Depending on the density of the film to be measured two separate measuring systems are used.
This means density values between 0D and 6D can be measured with 3 digits after the decimal point with a precision of 0.003 density values.
The spectral transmission function is evaluated with any number of response curves that can be programmed into the software. Hereby evaluating with the CIE (Commission internationale de l’éclairage) colour matching functions, colour metric data such as L*, a*, b* can also be measured.
