ColorWorkDesk CWD: next generation spectrophotometers

Identifying, measuring and controlling the quality of a colour is the task of an instrument as delicate as it is precise: the spectrophotometer.

Choosing the most suitable spectrophotometer for your business, configuring it correctly is an essential step, useful to optimize the performance of the software used for color management.

Spectrophotometers: precision at the service of colorimetry

A spectrophotometer is a device used in colorimetry not only to acquire and evaluate color, but also to identify it, find any matches and check its quality.

This precision instrument is capable of measuring any type of material: paints, liquid products, plastics, paper, metals, inks and fabrics. It is also designed and calibrated to detect both the visible spectrum and the ultraviolet component of materials.

These features allow operators to maintain color uniformity throughout all process stages, from concept to product delivery.

As the instrument that physically reads color, the spectrophotometer represents the first stage of the acquisition process.

It will be essential, therefore, to make sure to choose a type of spectrophotometer, suitable to meet your colorimetry needs.

Spectrophotometers VS Colorimeters: the difference is there

The spectrophotometer is not the only instrument suitable for color acquisition and measurement. On the market there are also colorimeters that although similar, offer lower level performance. To understand the reasons, it is necessary to understand how these tools work.

Operation of a spectrophotometer

The spectrophotometer, compared to the colorimeter, provides a complete analysis of the visible spectrum from 400 to 700 nanometers with measuring ranges of 10 nanometers.

The spectrophotometer can work in two ways:

  • By reflection: illuminates the sample and detects the reflected light through a probe. The reflected light will then be split down into monochromatic sources ranging from 400 to 700 nanometers, translated into numerical data, ready to be communicated and processed.
  • By transmission: illuminates and detects the light that passes through the sample. The light transmitted later will be split down into monochromatic sources ranging from 400 to 700 nanometers, translated into numerical data, ready to be communicated and processed.

 

Operation of a colorimeter

The colorimeter, unlike the spectrophotometer, does not measure monochrome sources between 400 and 700 nanometers, but quantifies only 3 results within this range, thus defining the quantities of red, green and blue light perceived by the eye.

Benchtop and portable spectrophotometers: the CWD range

In industrial applications it is therefore essential to choose the most suitable measuring instrument for your operational needs. It becomes equally important, therefore, to know every measuring geometry and every type of spectrophotometer available.

In this regard, URAI offers a wide range of benchtop and portable spectrophotometers, in which converge all the most modern technologies capable of ensuring high precision performance in color measurement.

This new generation of instruments with LED or XENON lighting technology, is equipped with pre-installed Color Quality Control software, different reading geometries (d/8 sphere, and 45/0) with connection via USB or Bluetooth ports.

Configure and calibrate a CWD spectrophotometer

The benchtop and portable spectrophotometers of the CWD range are easily configurable according to the needs of the operator.

Calibrating the spectrophotometer is a necessary step to ensure perfect operation that ensures optimal accuracy and performance over time.

Calibration in modern spectrophotometers is carried out by means of the calibration plate and white and the black trap.

Spectrophotometer lamps gradually change their condition and ability to create light.

Calibrating the instrument can, therefore, mitigate the negative effects of such criticalities related to the stability of the lamps and the cleaning of the lenses.

Connecting spectrophotometers to CWD software and technical support

The ability to connect CWD spectrophotometer models, via Bluetooth or USB, to ColorWorkDesk software or to your smartphone, on which the ColorWorkDesk app is present, makes them highly performing and user-friendly tools for the operator.

To this peculiarity is also added the possibility to update and implement the new models of spectrophotometers placed on the market, as well as that of configuring and coupling to the CWD software also different models of spectrophotometers or colorimeters already in use to the operator.

Once configured and connected, the spectrophotometer can be used independently by the user who can still use URAI assistance for its maintenance.

This can be a simple repair in the event of a failure or a thorough check of the instrument to verify its optimal operation. These specific instrumental controls provide periodic maintenance contracts, with interventions carried out by URAI technicians directly at the customer’s premises.

The best solution is the ColorWorkDesk system

CWD benchtop and portable spectrophotometers are therefore not only the top in terms of the latest technology and versatility, but also the most performing solution to be associated with the use of ColorWorkDesk software, and the dedicated app at the heart of the CWD system.
