Streets Imaging embraces RGB colour for all output devices for all digital printing. This is because Streets Imaging’s output is mostly to photographic paper which has yellow, magenta and cyan dyes which make up all of the colours visible in the photograph. This system is commonly referred to RGB since RedGreenBlue light sources are used to expose the paper regardless whether the sources are lamps, LEDs or lasers.
Even though our inkjet printers use CMYK (Cyan, Magenta, Yellow, blacK) inks, they are set up to receive RGB files so our workflow is consistent. Sending us files set up as CMYK will give unpredictable results.
