Does Your Pressroom Densitometer or Spectrophotometer Have an Expiration Date?

The short answer to this question is “no”. However, while there is no real expiration date on your measurement device, there are a few important factors to consider regarding the efficacy of older pressroom color measurement instruments. Just consider how the print market has changed and matured over the last 10 years or even the last 5 years. Do you really think your old densitometer or aging pressroom spectrophotometer still has the right mix of…

Should I Use a Densitometer or Spectrophotometer in My Pressroom?

Should I Use a Densitometer or Spectrophotometer in My Pressroom – this a question we hear all the time from printers across all segments of the industry. While the densitometer has been around for many years and has been widely adopted, there is no doubt that the momentum has now shifted towards using spectrophotometers in the pressroom. Today’s pressroom spectrophotometers (sometimes called “spectro-densitometers”), offer all of the capabilities of a densitometer and also have the…

Quantum Group Chooses the Techkon SpectroDens

Quantum Group states “We elevate digital printing and offset printing and set the standard for color and quality” which is precisely why they continue to invest in the latest printing technology.  A look at their About Us page reveals that they started in 1992 as a high-quality commercial sheet-fed printer and are continuing to evolve into a single source communications partner.  Quantum Groups’ high-tech presses can execute a complete range of print runs, from small…

An Affordable Scanning Solution for Printers

Techkon recently announced a brand new solution aimed at budget conscious printers looking for a scanning solution that allows them to see a visual representation of the results displayed by ink zone and printing units.  The solution utilizes the SpectroDens Handheld & Scanning Spectro-Densitometer in combination with Techkon’s Expresso software and serves a real need in the sheetfed offset market. Techkon has a long history of listening to their customers and coming up with solutions to meet…

Viewing Density Trends with Expresso Mini

ExPresso Mini is a SpectroDENS feature that shows print density trends as a bar graph. Press operators can use this capability to track trends across multiple sheets or across the press width. It is a simple tool to help maintain print uniformity. STEP 1: Use the up/down arrow buttons on SpectroDENS to select the Measurements Function menu on (bottom left menu). Scroll through the menu and select the Expresso Mini function.  Expresso Mini displays results…

A Functional Comparison of the Densitometer and Spectrophotometer

In deciding on the appropriate color measurement instrumentation, it is essential that you understand the operational characteristics, functional comparisons, and intricacies of both the densitometer and the spectrophotometer. This is best communicated in the in-depth instrument descriptions below. Densitometers Density is a measure of the absorbance of an ink at specific wavelengths of light. As an example, yellow ink has a maximum absorbance in the blue region, so its density is calculated using a filter…

What are M0, M1, M2, M3 Measuring Mode Settings

In accordance with the ISO 13655 standard, the “M” series of measuring mode settings were defined in order to standardize illumination conditions where optical brightening agents are utilized in substrates. The following is designed as a quick reference chart of the 4 different measuring mode settings within the “M” series. M0 “Color measuring mode A” spectral luminance factor without polarization filter under a light source that simulates standard illuminant A (gas lamps or LEDs, 2856…
