Production of high-quality color digital printing
November 11, 2008
The different phases of a color workflow involve increasingly the use of different devices that may speak a language of different color. Digital cameras produce entries with different RGB technologies, digital printing and offset systems use different technologies CMYK (and sometimes more than four inks) and test systems using other technologies CMYK. Each technology has its own characteristics and its own range of colors.
The increase in the predictability of the color and the reduction of errors in the delivery of color, from the generation of the file until the final output, requires a solution of objective management of color to match the colors of a device with the following and a color with another spacewhile maintaining the fidelity of the original image data at all times.
An essential factor to produce an effective color management solution is to ensure that procedures that control the color throughout the system are integrated and automated. Work without human intervention or interaction or practically without them - but offering options to color experts to refine and produce works of critical colors - significantly reduces the possibility of making mistakes.
Color management gains in importance to print with digital systems given that, unlike the offset, each device uses inks exclusive and the correspondence of color is even more difficult. In addition, the urgent nature of the digital printing leaves no time for corrections. While offset printing is a phase of adjustment, in the digital world work often produce upon request, which means that correspondence of color must be progress in the control console digital, allowing a correspondence in the first page.
The color management process includes generating ICC profiles or other universal converter between different languages and ranges of colours, both the source device and final output device. These two profiles are then combined to create a profile of full origin that guides the transformation between colorimetric performed by a module of correspondence of colors for all the color workflow.
Color servers think
The requirement that the digital printers were capable of producing digital colour fast, accurate and high quality on demand gave rise to the development of color servers think. Developed for production environments and based on a technology itself, these color servers incorporate automated tools of color management that can easily be adjusted to achieve a correspondence of color critique, and integrate perfectly with any flow of work or digital printing system.
On the basis of numerous characteristics, color server technology think offers all the necessary elements - uniformity, accuracy and smoothness - to achieve a high quality color over time and between devices. The functions of color management Device Link are a tool of creation of profiles to technology digital, together with the dynamic creation of profiles in real time for any pair of source and destination profiles. As a result of these capabilities, the current digital printing systems get the correspondence of color in works produced with the same file on a machine offset or even two different digital platforms.
Isolated time of products and solutions have been completed. Many service providers are creating mixed environments that take advantage of the best in digital technologies and offset. With effective management of colour in all its production center, print services providers keep their customers happy and make the most of growth opportunities offered by digital printing.
