  • Theory: Sublimation
    • Sublimation Transfer printing
    • Transfer printing
  • Sublimation printing history
      • 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
  • Sublimation transfer printing: how it works
    • Sublimation transfer printing process (SIT-Specialty Inks’ specialty for more than 20 years, as well in traditional as in inkjet printing processes)
    Phase 2 210°C, 30s Phase 1 Phase 3
  • Sublimation transfer printing (2) Paper: before transfer Transferred fabric Paper: after transfer
  • Sublimation transfer printing: A to Z
  • 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 = Sensient core expertise
      • Only certain dyes are suitable for the production of heat transfer paper
      • Selection criteria
        • Sublimation curve
        • Fastnesses
        • Shade (Core range)
  • Dye selection: sublimation curve
  • 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
  • Subli Inks - Fastnesses The light fastnesses have been measured at the maximal recommended dye concentration and a dilution of 1:9 (B: bluer). All other fastnesses have been measured at the maximal recommended dye concentration

  • 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.
  • 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.
  • 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.
