ChannelExtender for RGB to Multicolor separation: Use GMG color management directly in Adobe Photoshop

(Requires a GMG OpenColor 2.1.4 or higher.)

In the high-performance packaging variant separations from RGB into Multicolor color spaces can be created with up to seven target colors – on the basis of separation profiles from GMG OpenColor. Using the new ChannelExtender functionality, you can use devicelink GMG OpenColor profiles to separate the whole design from RGB to your custom GMG OpenColor project directly in Adobe Photoshop. GMG OpenColor transferres the precalculated separation profiles to GMG ColorPlugin via a direct connection. In this way image data can be adapted to the multicolor printing process in use.
Color Conversion from RGB to CMYK + up to 3 spot colors
Expanded Color Gamut (ECG) printing, also referred to as Fixed Color Palette printing, uses a standardized ink set enhancing the CMYK color space to reproduce any color used in the design. In the plugin, up to three additional inks can be used. The inks need to be between the CMYK process colors, i. e. Red or Orange, Green, and/or Blue or Violet.
This method allows a gamut expansion to reproduce more spot colors and also nesting print jobs with different color channels, without changing the ink configuration of the printing machine.
Using ECG, design can be more eye-catching, resulting in highly saturated colors. The print result is closer to the original RGB design. As the ink setup is standardized, printers are saving on make-ready and ink costs.

Soft proofing
The ChannelExtender allows you to switch on a color correct preview of the final print result. See in the image below: checkbox 'Preview'.


With the ColorBoost you can make images more saturated, colorful and eye-catching.

Tip: As an alternative to the global ColorBoost function which applies the ColorBoost to the complete image, you can use the Work Preview functionality to use Photoshops built-in tools to do selective color corrections on particular layers or marquee selections.

Work preview
The new Work Preview functionality allows editing of the original document in RGB while providing a color accurate simulation of the print result. The Work Preview automatically uses the correct GMG OpenColor profile for the Adobe Photoshop Proof Colors functionality.

MinDot Preview and MinDot Adjust - Spot color support

In MinDot Preview problem areas for flexography printing can be localized in the highlights. MinDot Adjust optimizes the print data on the basis of the tonal-threshold values of the print process used. In addition, the function can now also be used on spot colors and hidden or locked layers.

Extended MinDot Features

MinDot Preview does not add an entry to the Adobe Photoshop History anymore, as the preview does not alter the document.

Set with Curve: Transfers all color values below the defined threshold to the printable tone value range while keeping details in the gradients. To avoid a visible edge and to keep details, a curve is applied to the clipped values and to the color values slightly above the threshold, see black graph. Blue: 'Remove', Red: 'Set with clipping'. Former 'Set' renamed to 'Set with clipping'

Improved soft proofing with OpenColor Preview

GMG ColorPlugin now supports more than 8 profile channels.


Support of new characterizations FOGRA53 and FOGRA54

FOGRA53 is a CMYK based and media neutral color exchange space that primarily serves color communication throughout the print production, including copy preparation, job assembly, proofing, and process color printing. FOGRA54 characterizes a web offset heatset printing process using PS6 (super calendered uncoated SC-B) medium. Both characterizations are now available within the ColorConversion function.

Support of Adobe Photoshop CC 2018

GMG ColorPlugin 1.3 supports Adobe Photoshop CC 2018 on PCs. This Photoshop version was already supported on Mac.

Resolved issues

The following technical issue has been resolved in ColorPlugin
