Color measurement and control technology with Lithec quality retrofits

In cooperation with our partner, Lithec GmbH from Miesbach, Germany, we offer you advice on color measurement and control systems as well as inline and online inspection solutions for retrofitting existing offset sheet-fed printing presses.

High-quality equipment from Lithec completes our portfolio for quality assurance and industrial color management in printing plants.

Inline Color Control

Retrofittable color control options for accurate process control.

Online Color Control

Super-flexible online Color Control Systems for high demanding packaging applications and lower budgets

As experts for quality assurance in printing, you can rely on us to provide honest advice tailored to your individual needs. We have decades of experience in system integration, industrial color management and the preparation of color control systems for various application scenarios.

 Of course, Lithec color control systems are also suitable for modern process control approaches such as expanded gamut printing or gray balance oriented printing.

 If you decide to retrofit your existing Heidelberg, Koenig & Bauer, Komori, manroland or RMGT (Ryobi) printing presses with a Lithec system in combination with advice and training from us, you will receive an extended solution package at no extra charge compared to the manufacturer’s conditions. Guaranteed!

The performance update for your existing printing presses.  Increased value and performance. Waste reduction and stable ink feed.

The inline retrofit options LithoFlash and LithoFlash-Dyn enable your existing presses to catch up with new presses with integrated color control in terms of performance and color stability. Lithec’s color measurement and control systems are hundreds of times industry-proven and enjoy an excellent reputation for quality and reliability.

Lithec color control systems can be retrofitted to almost all printing presses. The user interface of the corresponding control software is clearly arranged and allows the operator to quickly get used to the operating elements. In addition, we offer suitable software for ink zone presetting so that the correct ink zone profile is sent to the press at the start of the job, further reducing start-up waste. The systems are extremely low-maintenance and do not disturb the press operator in the accessibility of the press, as the units are installed close to the impression cylinder, below the press gallery.

Experience significant increases in the performance of your existing printing presses at a low price. Increase your return on sales through reduced start-up waste, perfect color stability in production and minimize the risk of color fluctuation-related customer complaints.

Other products from the Lithec-range of color measuring and control systems:

LithoScan Professional. Color measuring table with maximum freedom of measuring positions for packaging printing.

LithoScan Professional, the online color measurement and control system for variable measurement in the image and in the print control strip. As an online solution (separate measuring table next to the printing press), the LithoScan Professional can be connected to several printing presses simultaneously. Measurement data is recorded spectrally and densitometrically according to the requirements of the print job. The ink slide control value change is calculated in fractions of a second so that the transmitted data has already reached the printing unit before the printer has left the measuring table.

The LithoScan Professional is also known as Densitronic Professional and, with a total of approx. 1500 installations worldwide, is one of the most successful systems of its kind. The LithoFlash-Professional is known among printers for its high reliability and outstanding precision in color control.

Thanks to the combined spectral/densitometric measuring head, the LithoFlash-Professional is ideally suited for applications in packaging printing and security printing where high ink film thicknesses and absolute stability of the ink feed are required. In addition, the LithoFlash-Professional offers a highly attractive price-performance ratio and upgrades any existing conventional printing environment.

LithoScan-Professional, the optimal solution for variable measuring requirements in packaging printing. It can be connected to several machines for shared use. 

Measurement of print control strips or directly in the image. Spectral and densitometric.

Sheet inspection. If the content has to be checked as well as the color.

LithoScan PDF. A complete inspection of the printed image against the original.
In some industries, such as packaging and pharmaceutical printing, it is essential to ensure that the printed sheet is matched against the original. The LithoScan PDF Inspection System is an online extension option that allows a pixel-accurate comparison to be made with the PDF template of the print job or a good sheet signed by the customer. The LithoScan PDF can be equipped with a 45°/0° or spherical all-round illumination (DOM illumination) of the inspected sheet, depending on the requirements of the application. The system can be connected to several machines at the same time. By simply selecting the template on the screen, the corresponding print job is preselected for comparison. The time for a complete scan of a typical 70cmx100cm print sheet is just 1.5 seconds. This allows a reliable and regular sample inspection and documentation of the manufacturing quality without significant additional time effort.
Detected errors are immediately displayed to the operator on the connected monitor. In the event of a persistent or unacceptable printing error, the printer can react immediately. Furthermore, the LithoScan PDF never gets tired and guarantees perfect detection of printing errors of any kind even during stressful times and night shifts.
