Windows 10 and later:

Right-click the (Windows) Start menu (Windows icon) and select Command Prompt (Administrator).

Working Color Space

A working color space is a transition color space used to define and edit color in applications. For each color space (RGB, CMYK, Grayscale, Lab), which is used in an application, it is possible to set separately which working color space profile is expected for data. You can select these profiles in the menu item Administration > Settings in the Color Management tab.

A working color space profile serves both as a source profile for newly created documents based on the corresponding color model and as a source profile for unmarked objects in a PDF file so that they can be used in color accounting during output.

  • New Documents: For example, if Adobe RGB (1998) is the current RGB working color space profile, all newly created RGB documents will use the colors of the Adobe RGB (1998) color range.
  • Untagged objects: For example, if there are unmarked RGB objects in a PDF file - these are referred to as Device RGB objects - the working color space profile set in the working color space is assigned to this profile beforehand in order to calculate the object in the output color space and then perform a color space transformation into the output color space.

A Color Space is a specific organization of colors. In combination with physical device profiling, it allows for reproducible representations of color, in both analog and digital representations. In our case this includes the following Color Spaces:

  • Black and White
  • Grayscale – a grayscale or greyscale image is one in which the value of each pixel is a single sample representing only an amount of light, that is, it carries only intensity information.
  • RGB – The RGB color model is an additive color model in which red, green and blue light are added together in various ways to reproduce a broad array of colors.
  • CMYK – is a subtractive color model, used in color printing, and is also used to describe the printing process itself.
  • Lab – the absolute (mathematical) color space with which the light perceived by the human eye can be imaged.

White Gap

A small gap/misalignment of colors on traditional presses leading to  missregistration. e.g. print a red (M100, Y100) text on a black or blue background consisting of C and K. If the colors are not aligned properly, there could be small areas of not-printed substrate which are clearly visible, as white gaps.
