A Commercial Print Workflow - Scenario Two 45 scan RGB ⇒Press CMYK Monitor RGB ⇒Press CMYK Press CMYK ⇒ rev Press CMYK Press CMYK⇒ Monitor RGB Press CMYK⇒ Proof CMYK Color Transformation Color- Render Capture-referred data is retained in RGB for image Capture adjustment and job assembly (alternatively — perceptually colorrendered to an intermediate ‘standard’ wide gamut RGB) Scan originals Capture computergenerated (CG) illustrations Entire job is colorrendered to CMYK, for exchange and/or for production (single vendor profiles and possibly CMM) Color Calibration Color Characterization Color Aim Implementation Color Source Specification Color Communication Assemble Softcopy visualization is a part of image adjustment — more reliance on CRT calibration and characterization Can result in significant cost savings when image adjustment does not require rescan Source profile metadata must be managed for Create layout design and Select objects prepress RGB (also Normalize formats final exchange Combine objects CMYK) Configure job Print production Adjust T2B - Color Management A.
