Color Conversion: apply standard or custom profiles

Using ColorConversion, you can convert an image to a new printing condition. For example, if the original design was created for ISO Coated v2 and later it is decided to use the process standard PSO Coated v3. You can either preserve the existing separations or reseparate the image. You can also use GMG InkOptimizer to minimize the ink usage.

Source Space

By selecting the source space, you define the input color space of the document you want to convert. If the document has an ICC profile assigned to it, it will automatically be preselected as Source Space.

Destination Space

The destination space is the target color space you want to convert your image to. All GMG conversion and separation profiles are certified according to official print standards.

• RGB-to-CMYK: The RGB-to-CMYK standard conversions use a special gamut mapping to minimize visual changes when reducing the larger RGB color space to the smaller CMYK color space.
• CMYK-to-RGB: CMYK data is converted to RGB from a print standard such as ISO or GRACoL to a print process neutral AdobeRGB color space (or vice versa). CMYK-to-RGB conversion is particularly useful for normalizing CMYK images in multiple color spaces to a common color space.
• CMYK-to-CMYK: CMYK data is converted from a print standard such as PSR, ISO, GRACoL, and 3DAP to another (CMYK) print standard. Using four-dimensional DeviceLink profiles, the source and target values are computed directly in CMYK—without using CIELab as an intermediate color space. The black channel separation from the original data is preserved when transforming into the target CMYK color space, preserving the visual impression of the document.
• Reseparation: CMYK data is reseparated to harmonize different UCR/GCR settings for a consistent color channel separation, delivering a highly stable and reproducible print result.
• InkOptimizer: CMYK data is reseparated to optimize the color composition (gray balance) for a specific printing condition and for a specific Total Area Coverage (TAC). InkOptimizer profiles reduce the quantity of CMY inks while increasing the proportion of black ink without changing the visual color impression of the print. (Requires a ColorPlugin Pro license.)
• Custom: RGB, CMYK, or multicolor data is converted according to your own profiles created in GMG ProfileEditor or GMG OpenColor. 

Load Custom Profile

You can also apply your own color conversion or separation profiles created in GMG ProfileEditor or GMG OpenColor. For quick access to often used profiles, you can also store several profiles in the profile library.

Conversion Options

• Replace Assigned ICC Profile: Replaces the assigned ICC profile (output intent) of the open file after the color conversion. The replacement is prerequisite for a correct softproof view of the conversion. 
• Process Hidden Layers: Choose whether hidden layers are also converted.
• Unlock and Process Locked Layers: Unlocks and converts locked layers.
