CHAPTER 1 – General Description

Chapter 1

General description of the measurement system

1.1 Product description

High quality and productivity

The new generation of the proven Scan-Measurement System SpectroDrive com-

bines decisive advantages: Precise measurements thanks to an ISO-compliant

measuring head, technical reliability and high measurement speed. It can be fully

integrated into the printing process. The result: a productivity and quality boost

for your printing press.

The system consists of two components: The motorized measurement device scans

the complete color bar on a printed sheet within seconds and simultaneously sends

the spectral measurement data wirelessly to the PC. Here all relevant information for

controlling the printing press is clearly displayed by the TECHKON ExPresso 4 software.

Increase protability

Due to the trend of smaller print jobs and shorter press runs the time from starting a

press to getting it “in color” and running with consistent quality is cost critical. Spectro-

Drive reduces this “non-productive” and therefore expensive set-up time dramatically.

You will increase protability thanks to substantially reducing paper and ink waste and

getting more precious time out of your printing press. The system makes your printing

jobs predictable and calculable. In addition, the complaint rate will go down signi-

cantly and your customers will appreciate the sensible gain and reliability of the print

quality. ISO-compliant printing becomes easier than ever before.

The high rate of return of investment is amazing. The relative low – and only one

time – investment will show in recurring prots almost immediately. Also older print-

ing presses get a productivity boost thanks to SpectroDrive.

Ease of use and high speed measurement

Setting up a printing press can be compared with starting a jet plane. It is a time-

critical process, where the press operator – like a pilot – must observe and perform

a multitude of important tasks at the same time. Hence, during the development of

SpectroDrive great care was taken in delivering a system that is easy to use and fast, to

make working with SpectroDrive even more intuitive and convenient.

Manual TECHKON SpectroDrive

For example, a laser beam can be activated to support the exact positioning of the

print control strip. Furthermore the measurement device has only one button to start

the measurement process. Installation is simple as well. After a few minutes the system

is operable and ready to take measurements.

Due to its aluminum unibody case the new SpectroDrive is particularly robust and

reliable. Of course SpectroDrive is able to handle variable scan lengths and ts to any

printing press format. The battery charging is inductive, fast and sustainable.

Two measurement systems in one

This statement relates not only to the technical fact that the spectral measurements

allow displaying densitometric and colorimetric data. It also points out that Spectro-

Drive can be used as a scanning device as well as a hand-held instrument for single

measurements. Just take the device from the horizontal track and position it wherever

you want to take a color measurement. SpectroDrive now also features an integrated

display that shows the measurement values of spot measurements directly at the de-

vice.

Software ExPresso

The Windows software TECHKON ExPresso 4 has a self-explanatory user interface

which can be operated via touch-screen. The software oers a comprehensive tool

set comprising measurement of spot colors, support of up to 16 print units, front-side

and reverse printing, display of color density, dot gain, gray balance, CIE L*a*b*-values

and recommendations on how to adjust the ink on the press. This is only an extract of

the complete functionality.

Thanks to its modularity TECHKON ExPresso 4 is expandable and versatile. The mea-

surement data can be exported into other software applications that connect real-

time to printing presses to enable a “closed loop” turn-key solution. In addition, the

ExPresso software can export measured data to standard applications such as Micro-

soft Excel™.
