Applications for DeviceLink profiles

• DeviceLink profiles complement the use of normal ICC profiles by producing substantially better results in terms of both quality and the printing process when converting and adapting colors during color conversion.
• The principal application of DeviceLink profiles is the transformation of "separated" CMYK data to a different CMYK. The aim of reseparation can be to harmonize different separations or to use more black in order to stabilize the printing process and/or save ink.
• DeviceLink also have benefits when converting from CMYK to Grayscale owing to the preservation of 100% black, which would not be possible with normal ICC profiles.
• DeviceLink technology also offers attractive, new approaches to quality optimization, especially for RGB-to-RGB or RGB-to-CMYK and CMYK-to-MultiColor conversion. The impressive result: pure, highly saturated colors and the same color appearance.

Standard DeviceLink profiles Features

Limiting the total amount of color (TAC) for various printing standards

e.g. ISO, Fogra, ECI, Ifra, Gravure (PSR), GRACoL, SWOP, SNAP.

Optimized color conversion between different printing standards

These color conversions preserve separations, limit the TAC in accordance with the selected printing standard, and preserve the purity of primary and secondary colors. They ensure smooth transitions in vignettes and permit correct transformation of PDF files.

Ink reduction (SaveInk)

The ColorLogic DeviceLink profiles for ink reduction preserve the separation characteristics while at the same time replacing CMY with black. This leads to far better transformation than classical ICC-based conversion with strong GCR.

CMYK-to-Grayscale conversion profiles

When converting CMYK data to Grayscale using ICC printer profiles, a tone composed of pure, 100% black – such as black text – cannot remain 100% black owing to the architecture of the profiles. Instead, it is converted to 95%, for example, depending on the printing process involved. On the press, this leads to rasterizing and thus to unsharp printing results. The CMYK-to-Grayscale DeviceLink Sets retain 100% black.

RGB-to-CMYK separation profiles

Depending on the quality of the printer profile used, conversion from AdobeRGB, sRGB or eciRGB_V2 to the various printing standards can give rise to annoying artifacts in some areas. For instance, smooth RGB vignettes often have a much less smooth structure after conversion to CMYK, highly saturated RGB colors lose their saturation, and losses of definition may also occur, depending on the rendering intent used. The ColorLogic separation DeviceLink profiles are optimized for conversion of AdobeRGB, sRGB and eciRGB_V2, meaning that the above problems are avoided.
