Roland DG Corporation Releases New Densitometer


The VW-S1 specialises in density measurements required for colour matching and is designed to be easy to operate by simply tapping the tip of the VW-S1 against the relevant colour in the colour chart specified by VersaWorks 6 and pressing the button.

Roland DG’s inkjet printers are bundled with its VersaWorks 6 RIP and print management software that provides a broad range of functions to streamline users’ printing operations. According to Koji Takahashi, Project Manager at Roland DG Digital Printing Business Division, one of the important functions of VersaWorks 6 is colour matching, which accurately controls colour differences between printers. The colour matching function between printers is valid only when using the same model printers with the same ink type and configuration. Files must be printed with the same print settings, including ‘Media Type’ and ‘Print Quality.’

Its process involves printing a colour chart for each printer that needs to match colours, then measuring the results with a spectrophotometer to generate individual values that are compared and automatically adjusted for. Using a spectrophotometer is considered essential for this process.

‘Until now,’ Takahashi said, ‘users needed to purchase their own commercially available device. Customers complained about the cost and the difficulty of learning another device. In response to customer feedback, our new VW-S1 densitometer was developed for VersaWorks 6 based on the concept of being affordable and easy to operate for anyone.’

Measurements can be completed quickly, with a 4-colour chart taking approximately one and a half minutes, and a 6-colour chart taking around two minutes. ‘The device is also ultra-compact,’ Takahashi added, ‘with a size similar to a penlight, which makes it easy to use and store just about anywhere.’

‘If you produce volume work from one client with multiple printers, or print a large, combined graphic with two printers, the final output from each printer needs to be as consistent as possible,’ Takahashi said. ‘The VW-S1 makes it easy for anyone to do colour matching with reliable printing results. It can also be used to match the original colour of a printer that is slightly off compared to when it was installed due to aging or replacement print heads, which provides peace of mind to clients when printing repeat jobs.’

‘We will continue meeting the specific requirements of our customers in order to increase the quality and efficiency of printing operations and we hope to contribute to the development of even more creative business opportunities in the future,’ added Takahashi.
