How to use the TECHKON DENS?

Your new test on DENS comes with a manufacturer's certificate, a short manual, a USB cable and of course the instrument itself. The device is switched on by pressing the dens button and is immediately ready to measure.

If the device is off, press the dens button to turn it on. First, we need to calibrate. For the DENS with Status E and polarization filter placed the measurement head of the dens on top of a blank area of the paper sheet and press the Cal button. A successful calibration will be indicated by three horizontal lines. You can now quickly and easily measure solid CMYK touches. You can also measure the DOT% set of patches to calculate Dot Gain. First change the mode and then calibrate then measure a solid patch cyan in this case and then the dot percent patch.

Here I'm measuring a cyan 40% and 80%. The effective dot area of each patch is shown. The dot gain is simply calculated by the effective dot area minus the patch value. In density mode, you can also measure grey balance from a grey balance patch, that has the correct dot percent to achieve a neutral gray when printed correctly. This is cyan 50%, magenta 40% in yellow 40%, no black. The density values measured should be in close range to each other to ensure neutral grey balance without a colour hue, colour shift or bias.

There is also a precision magnifier or lupe, this can be used by placing it on the spot to be checked and pressing a lens button to activate the light. As long as the lens button is pressed, the magnifier will be lit. The dens will turn off after one minute if not used. To recharge, use the supplied USB cable and plug it into a USB port on a Mac or a PC or another USB power source. Completely charging an empty battery will take approximately four hours. Dens has regulated charging management; this means it will power charge an empty battery so the device can be used again after a few minutes. On the other hand, there is no overcharge of a full batteries.

Up to ten thousand measurements can be carried out with one battery charge. TECHKON DENS, straightforward accurate and very very easy to use. You can download the detailed menu on techkon.com or contact me at colourgraphicservices.com

By Techkon

Photographers use polarization filters to cut out glare. On color measurement devices, the use of these filters minimizes differences due to gloss. Differences in appearance from specular reflection can come from paper coating and from ink finish. Also drying of wet ink changes the appearance. Whether a surface is glossy or matte can impact color measurement. 

There has been debate about the use of polarization filters and there are different camps. As always, it is important to understand both sides of the issue and see what fits your situation.
