Ranking Tips for Selecting the Best Spectrophotometer

2 min

Quality control isn’t possible without making measurements, and a spectrophotometer is essential for such measures. There are several models on sale and manufacturers to select from. You should select a spectrophotometer that suits your needs. A spectrophotometer detects and quantifies the ethereal composition of light and interprets the outcomes into color connected to data. There are plentiful forms of color data, but the predetermining of color facts in the CIELab format is the foremost known and used. When picking a spectrophotometer, there are various aspects to pay attention to, mainly ensuring it’s suitable for the substrate you’re measuring. One spectrophotometer cannot measure all sorts of substrates; for example, when measuring transparent substrates, you’ll require a backlit function, and several spectrophotometers don’t support this. To get the best spectrophotometer like Agilent UV VIS spectroscopy, below are the top tips of consideration.

Substrates are vital

Concluding on which printed substrate you’re going to measure must be the first separating point to what form of a spectrophotometer to acquire. For traditional substrates, such as vinyl and paper, many spectrophotometers on sale will do. Devices from the best manufacturers will then vary in price based on the accuracy, speed, and special features they come with. When measuring transparent substrates, you cannot go wrong with a spectrophotometer with a backlit function, devices that aren’t ordinary on the market. For tricky substrates like prints with metallic inks, choose a spectrophotometer with sphere technology.

Software and special features

One of the vital specifications has been labeled for your spectrophotometer. There are more functions and features to consider before you make the final decision. First, ensure the control software is simple for you to utilize. Does the app incorporate an interactive manual? For handheld devices with in-built screens, ascertain the screens are effortless to read with readable and clear text and icons.  A handy feature is great to connect and transfer records wirelessly; hence is it supported? Another aspect to check in the control system is a dependable color library for renowned ink standards. You may wish to utilize your spectrophotometer as a densitometer, and it should be capable of. However, when gauging wet ink, you likely want to employ a polarization filter. If so, ensure your spectrophotometer has or can be connected with a polarization filter, or you may not obtain consistent densitometric measurements.

Quality and speed

After narrowing down your selection to types of spectrophotometer that compute most of your substrates, it’s time to consider the number of measurements you’ll make daily, weekly, or monthly. For more measurements, get a spectrophotometer such as Agilent UV VIS spectroscopy that has meaningful speeds. And there can be relatively significant variations between models. When gauging reference test orders to build excellent ICC profiles for a particular device, you may have to measure many test graphs with 1,500 or more patches. This is nearly impossible to do with a handheld spectrophotometer since it does not support scanning mode. Quality is hard to define, but one sign is the sampling interval and the amount of spectrum measured.  Also, check the repeatability between measurements and the anticipated readability between various spectrophotometers of a similar model.
