ColorConversion: Converting an Image to a New Printing Condition

Using ColorConversion, you can convert an entire 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. Also, you can 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.

Load Custom Profile

With a GMG ColorPlugin Pro or Packaging license, 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.

This feature allows you to use Multicolor Project to Multicolor MXN profiles created in GMG OpenColor as custom profiles in GMG ColorPlugin. GMG ColorPlugin offers an almost unlimited flexibility to swap or replace colors in the final stage of production. You are free to convert any combination of process and spot colors to any combination of colors by a single mouseclick. 1–7 input colors and 1–8 output colors are supported!

  1. Open a CMYK or RGB image in Adobe Photoshop.
  2. Click File > Automate > ColorConversion or click ColorConversion in theplugin panel.
  3. Select a Source Space and a Destination Space and click OK to convert your data.

ColorConversion.

In the example, the image will be converted from ISO Coated v2 to PSO Coated v3, preserving the separations and replacing the assigned ICC profile accordingly.

  • 1–7c multicolor to CMYK
  • 1–7c multicolor to 1–8c multicolor
  • 1–7c multicolor to ECG, i.e. CMYK+3c
  • Adapt to new media type or paper tint

It is possible to remove spot color channels and replace them by CMYK, to significantly reduce production costs. For example, a document delivered in 7c can be "normalized" to CMYK with the ColorConversion feature and then reseparated with ChannelChanger (or with another Multicolor Project to Multicolor profile).

Also, you are able to keep the channels and only adapt the document to a new target printing condition, for example, a different media type or paper tint.

Simply calculate a Multicolor Project to Multicolor profile in GMG OpenColor and load it as a custom profile in GMG ColorPlugin.

GMG ColorPlugin shows a Channel Mapping dialog box where you can check the channel mapping and correct it in case the channel names in the profile are different than in the document.

The conversion will be applied to the selected image area or to the entire image if there is no selection.

The document will be flattened during the conversion with a Multicolor Project to Multicolor MXN profile.
