Digital Dye Sublimation RGB versus CMYK

This summarizes workflow considerations for digital dye sublimation:

• RGB - In most cases it is best to follow the recommendation of the International Color Consortium (ICC) and use the RGB color mode in Illustrator and Photoshop. Let the RIP convert from RGB to CMYK. See the ICC white paper on workflow management for more details. We have found the sRGB or Adobe RGB (1998) profiles that are standard in the Adobe workflow work quite well, but you may want to consider updating the standard sRGB profile with its ICC replacement.
• CMYK - If you want to design in CMYK, you may need a CMYK-Link profile or you can modify the CMYK profile in the Adobe workflow to reflect your printer and ink. Not all RIPs support a CMYK-Link profile.
  
  The standard CMYK profile in Adobe is U.S. Web Coated (SWOP) v2. This is a CMYK working space profile based on the U.S. standard for publication printing presses, governed by the Specifications for Web Offset Publications (SWOP). This standard was developed in 1972 for publications such as magazines and catalogs printed on offset presses and is not a match for digital dye sublimation printing.
  
  If you use CMYK, your input values may be changed by the RIP. For example a value for Pantone 186 C which might be C:0 M:100 Y:75 K:4 could be changed significantly to C:0 M:90 Y:70 K:12 on output. This is RIP dependent.
