Definition in the specification
Table 66 · Additional Entries Specific to an ICC Profile Stream Dictionary
ISO 32000-1:2008, §8.6.5.5 · PDF page 158 ↗
/Alternate array or name
(Optional) An alternate colour space that shall be used in case the one specified in the stream data is not supported. Non-conforming readers may use this colour space. The alternate space may be any valid colour space (except a Pattern colour space) that has the number of components specified by N. If this entry is omitted and the conforming reader does not understand the ICC profile data, the colour space that shall be used is DeviceGray, DeviceRGB, or DeviceCMYK, depending on whether the value of N is 1, 3, or 4, respectively. There shall not be conversion of source colour values, such as a tint transformation, when using the alternate colour space. Colour values within the range of the ICCBased colour space might not be within the range of the alternate colour space. In this case, the nearest values within the range of the alternate space shall be substituted.
Qualifier: Optional
