Invention by SUBLISTATIC in France, mid sixties
Development starts in fashion goods
Penetration in home furnishing in the mid eighties
Non-textile applications in development

Substrate selection
Selected disperse dyes can sublimate and have affinity for
selected substrates:
Man-made fibers:
polyester (PES)
(polyacryl (PAN))
(polyamide (PA 6.6))
coated or laminated materials polymers

Dye selection: Fastnesses and shade
Fastnesses
Substrate dependent
Concentration dependent
Selection according to the “weakest link in the chain”
Independent on the printing technique
Shade
A minimum of number of dyes must give the maximum number of shades
Such a selection is called a core range
Result of a time-consuming screening of the sublimation dyes

FAQ
The color on the paper is not right.
We can judge a color only after transfer.
Standard transfer condition
Temperature: 210°C, Time: 30s
These settings are standard for 100% PES fabrics. Depending on the substrate (fabric or hard substrate), other conditions may be more appropriate. In case of fragile substrate, it is indeed possible to reduce the temperature and still obtain an optimal transfer by increasing the transfer time.

27
FAQ
Release is bad.
Control paper side. The rough side is usually to be used.
Control press or calendar temperature.

FAQ
Suitability for outdoor application
The light fastness reachable by the dye-sub inks is in general limited. Thus a UV-protector is recommended and it is in any case necessary to test whether the end product fulfils the requirements of the application. No extrapolation for outdoor fastness should be drawn from the light fastness rating performed according to the ISO105-B02 norm, which attempts to reproduce indoor light conditions.
![Page 29: Sublimation workshop cairo 28.09.10 rg gd - sensient](https://reader036.vdocuments.us/reader036/viewer/2022081413/54654a2aaf79590f738b67dc/html5/thumbnails/29.jpg)
29
FAQ
Which substrates are suitable for transfer?
100% PES fabric is the optimal substrate for sublimation transfer printing. However other synthetic materials (Polyamide, Polyacryl …) can be applied as long as testing has shown their suitability.
