  • ISO 12647-2, PSO standardised


    ISO 12647-2:2013 and PSO out of the box

    The built-in CKP standardisation toolset is not only helping your print standardisation but all measurements and settings can be compared and set to the given standards. All ISO 12647-2:2013 standard referencess and the latest MediaStandard PSO references are preprogrammed and ready to use for different paper types. CKP automatically detect test strips and works with ISO / PSO and in-house references as well.


    Setting-up and keep in-house standards is very easy. The integrated color reference data and the unlimited number of spot channels can be easily integrated to the standards. Tools for CTP plate linearization, TVI curves and our unique ColorLAB functions are also integrated.

  • Speaking the printer's language

    All of the user interfaces and functions are designed together with press operators and with print house managers.

    Speaking the printer's language

    Color Key Pro (CKP) is veary easy to understand, learn and implement. User friendliness is reflected in all details of the system. At the time of installation all education and exams can be done, so no later training required. An average press operator could operate Color Key Pro form day zero, naturally.

    Perfect settings automatically

    The main screen of the system helps the press operator to visually control the settings of the whole sheet with a preview of each inking zone. All current colour / density measurements are displayed as well as the standard reference and aim values. No manual setting of the console is needed, all corrections and settings are uploaded automatically.

    From CTP to Print

    Tone value increasement (TVI) compensation, and the ideal colour /density aims are controlled by the system. The Color Key Pro TVI toolset helps the CTP operators to linearize and standardize their output. All standardization aim values are pre-programmed and the CKP system helps the standardization procedure with automated functions.

    Total inking control

    The advanced inking control functions are helping to reach the ideal settings based on the actual measurements of each printing unit. Ductor, ink response, ink key opening and tone value increase are measured, controlled and documented. The required corrections are calculated automatically and can be uploaded to the printing machine's control unit.
  • Take their words.

    There are no two identical printers as there are no identical scenarios. All of our installations are customised to our customer's needs to match their workflow, quality requirements and every day tasks. Savings and reducing waste is just the starting point, with Color Key Pro all of our customers have several additional benefits and savings. Take their words.

    Nevelland Graphics, Belgium

    At Nevelland Graphics we arrived when all of our competitors failed. At this video you can see why they chosen Color Key Pro over the competition and what are the unique benefits they get with our system. 

    Galleria Grafica, Spain

    The aim of Galleria Grafica in Spain was to save as much waste as possible. They chosen Color Key Pro because of the rapid ROI (less than 1 year in this case). Beside of savings the y reached another goal: client satisfaction because with CKP they have even print quality at their short and long print runs also.

    Gráficas AGA, Spain

    At Gráficas AGA we installed our system on their KBA Rapida 142. The automated ultra fast console and inking settings with the spectrophotometric colorbar measurement helped this printer to save time, waste and increase their print quality.
    A simple case for us but a big leap for the printer.

    Our booth at Drupa 2012

    At Drupa 2012 the X-Rite news team visited our booth. They checked our demo device simulating a printrun with an attached X-Rite EasyTrax measuring device. Our CEO introduced some of the advanced features of Color Key Pro (CKP) Pressroom Optimizer such like the printed job reporting. 
  • Our history

    From local to global. From easy to easier.

    The story of CKP was started as a custom development more than 10 years ago to fulfil the needs of a quality aware local printer in Budapest, Hungary. After we seen how our solution was growing and getting more and more capable we decided to enter the local market with the product: Color Key Pro.  At 2010 we started the development of a very special project and after 2 years of hard working we decided to step further and introduced our first in-line measurement and control solution at DRUPA 2012. After a very successful year with over a dozen installations at Belgium, Germany, Finland, Hungary, Slovakia, Spain we reached a new milestone and extended our international sales and support team. Now, after more installations than we ever expected we are here to bring what we do the best - our most advanced pressroom control system: 
    Color Key Pro (CKP) Pressroom Optimizer.
