Sublimation ICC profiles are created by scanning the media after sublimation for more accurate colours
Why would you create an ICC profile from an item sublimated on polyester then use that profile when pressing on a different media type ?
A wider range of tones and closer match to the original colours is achieved by using an ICC profile created around the media type you are pressing - custom icc profiles are better if you are trying to colour match a specific design.
ask yourself these questions
1: If you have an icc profile what was it created from ?
2: Are you using it on the same or similar media type ?
3: Are you getting the best results you can from your current setup and supplies ?
Here are some examples of some images that have been sublimated onto products and then scanned into an image file
The source ICC profile was made on metal then we used this profile on other media types and then compared to an icc profile made around the specific media type.
The images do show what we expected - but please bear in mind these are sublimated scanned images - looks much better sitting here looking at the physical products.
