Selecting the correct settings in Photoshop will ensure accurate results when viewing and printing.
It is important to make sure all images that you work on have an embedded profile. This is usually (but not always) sRGB for digital camera files and Adobe 1998 for scanned images. Photoshop has a colour settings panel that determines how it handles the colour management of the files that you work on. Once set this can be, in most cases left alone.
Spectrum’s recommended settings have been saved as a file that can be downloaded then loaded into the colour settings dialogue box and saved as your default colour setting.
