Techkon, a German developer of densitometers, spectrophotometers and software for colour control with a North American division in Danvers, Massachusetts, unveiled its new PressLink technology, describing it as a “closed loop print colour control solution.”
PressLink is comprised of hardware and software components that, Techkon explains, enable both automatic presetting of the ink fountains at the start of a press run as well as continuous automatic adjustments based on target values throughout the press run. PressLink runs based on a range of industry-accepted file formats and is compatible with most press manufacturers.
The system connects prepress directly to the press using Ink Presetting software. As the press starts running, the operator scans press sheets with the SpectroDrive to ensure the accurate density has been achieved. If accurate density is not achieved, then Techkon Expresso Software will send the right settings to the ink keys to make the necessary adjustments on the fly, thereby providing closed-loop colour control.
PressLink is available in thee different packages, as well as in custom configurations, including:
PressLink Ink Presetting
Calculates ink coverage for each ink zone and all colours based on CIP3, JDF or TIFF file from prepress. Automatically presets press ink keys for optimal ink coverage.
The Techkon SpectroDrive automatically scans entire colours bars while simultaneously sending spectral colour and density measurement data wirelessly to a PC running Techkon software.
PressLink Closed Loop System
The Techkon SpectroDrive measures press sheet colour bars and automatically adjusts press ink keys to maintain optimal ink coverage. Ink keys are set based on target density or minimum achievable Delta E.
