Notes:

  1. The release coating must not be silicone based.
  2. Substrates to be printed must be tested for suitability with the ECOTRANS® SI ink system prior to production runs being carried out. Always test application fully before beginning production run as there is often considerable variance in substrates from different manufacturers and even between different batches.
  3. The release substrate and application substrate must be STANDARD 100 by OEKO-TEX® Class 1 compliant to ensure the heat transfer labels produced with ECOTRANS® inks, additives and adhesives are STANDARD 100 by OEKO-TEX® Class 1 compliant. 

Usage Instructions

Recommended Usage

  • ECOTRANS® SI Crosslinker (80-20-XL) must be added to ECOTRANS® SI (80-20-) inks at 8% immediately before printing and mixed thoroughly.
  • The inks are now ready for printing. 
  • Each print layer must be thoroughly cured at a minimum of 140°C and for a minimum of 120 seconds to ensure thoroughly dry before additional layers of inks are printed.
  • The final print layer must not be cured to allow the ECOTRANS® Hot Melt Powder to stick to the surface of the ink.
  • Apply the ECOTRANS® Hot Melt Powder to the final print layer and remove excess.
  • Cure at a minimum of 140°C and for a minimum of 120 seconds.


When Curing Temperature of 140°C Cannot Be Attained

  • ECOTRANS® SI Accelerator (80-AD-AC) must be added to ECOTRANS® SI (80-20-) inks at 1% immediately before printing and mixed thoroughly.
  • ECOTRANS® SI Crosslinker (80-20-XL) must be added to ECOTRANS® SI (80-20-) inks at 8% immediately before printing and mixed thoroughly.
  • The inks are now ready for printing.
  • Each print layer must be thoroughly cured at a minimum of 120°C and for a minimum of 120 seconds to ensure thoroughly dry before additional layers of inks are printed.
  • The final print layer must not be cured to allow the ECOTRANS® Hot Melt Powder to stick to the surface of the ink.
  • Apply the ECOTRANS® Hot Melt Powder to the final print layer and remove excess.
  • Cure at a minimum of 120°C and for a minimum of 120 seconds.


Notes:

  1. ECOTRANS® SI (80-20-) inks mixed with ECOTRANS® SI Crosslinker (80-20-XL) have a pot life of 4 hours.
  2. ECOTRANS® SI (80-20-) inks mixed with ECOTRANS® SI Crosslinker (80-20-XL) will irreversibly harden after 48 hours.
  3. Standard Wash & Durability Performance will be achieved 24 hours after application.

Usage Recommendations

  • The optimum print room temperature is 18-20°C.
  • The optimum relative humidity is 50-60%.
  • We recommend using in a well ventilated area.
  • We recommend that tunnel dryers are turned on and allowed sufficient time to reach the required drying temperatures before printing commences.
  • Silicone inks are very sensitive to chemical contaminants. Ink preparation, mixing and printing should take place in clean conditions with clean equipment.
  • The screen emulsion must be suitable for use with silicon based inks and solvent based cleaners.
  • For Mixing White (80-20-M-WHITE) ink we recommend printing two layers with a screen mesh of 61T. This will produce a thicker ink layer giving excellent stretch, opacity and wash performance.
  • For other colours we recommend printing one to two layers with a screen mesh of 90T depending on colour density required.
  • We recommend a square edged triple layer squeegee with 65/95/65 shA.
  • The squeegee must be suitable for use with silicone based inks and solvent based cleaners.
  • For best registration it is recommended that the substrate is conditioned to the ambient temperature and humidity of the print room prior to printing.
  • We recommend that ink is replenished onto the screen in smaller quantities more frequently rather than larger quantities less often to keep the screen open. This will improve production efficiency and reduce downtime as printing will not need to be stopped for screen cleaning.
  • If printing is interrupted for more than 4 hours then the screen mesh must be cleaned thoroughly to avoid ink drying in the screen 
  • We recommend to only mix the required quantity of ink and crosslinker to reduce wastage.

Wash Up

  • Remove excess ink from squeegee and screen mesh immediately.
  • Remove any remaining ink from the screen mesh with ECOTRANS® SI Cleaner (99-10-8019).
  • Ensure all ink is removed from the squeegee and screen mesh to avoid damage.

Frequently Asked Questions (FAQ)

1. Why are my printed substrates sticking together (blocking)?

  • This is often caused because the prints have not been thoroughly cured.
  • Consider reducing the quantities of ECOTRANS® SI Reducing Medium T (80-AD-RMT) additive to reduce ink curing time.
  • Add or increase ECOTRANS® SI Accelerator (80-AD-AC) additive to reduce ink curing time.
  • Ensure the curing temperature and duration is correct.
  • Consider increasing the curing temperature and/or duration for larger print designs.
  • If printing on a roll-to-roll screen machine, adjust re-wind tension to prevent rolls being re-wound too tightly. 


2. Why are my prints suffering from pin-holes?

  • This can be caused by dust, other particles or dried ink blocking the screen mesh. Ensure the screen mesh is thoroughly cleaned.


3. Why are my prints not opaque? 

  • This can be caused by dust, other particles or dried ink blocking the screen mesh. Ensure the screen mesh is thoroughly cleaned.
  • Consider double flood / double stroke options to increase the volume of ink printed.
  • Consider reducing the quantities of ECOTRANS® SI Reducing Medium T (80-AD-RMT) and ECOTRANS® SI Accelerator (80-AD-AC) if wanting to produce the most opaque prints.
  • Ensure screens are in good condition with a consistent mesh tension across the screen.
  • Consider using additional layers of emulsion to make a high build screen to increase the volume of ink printed.
  • Consider a screen mesh with a lower screen mesh count to increase the volume of ink printed.
  • Consider using a screen mesh with thinner threads.


4. Why are my prints showing mesh marks?

  • This may be caused by the thickness of the screen mesh filaments preventing an even coating of ink. Where possible use thinner threads or a finer screen mesh.
  • We recommend printing two layers of ink to reduce this effect.


5. Why are my prints missing details?

  • This can be caused by dust, other particles or dried ink blocking the screen mesh. Ensure the screen mesh is thoroughly cleaned.
  • Dust or other particles can also settle onto the substrate preventing the ink from printing correctly.
  • Ensure the screen snap-off distance is uniform to prevent uneven squeegee pressure distorting the print.
  • Consider using a dyed/yellow screen mesh instead of a white screen mesh for sharper prints.
  • Ensure screens are in good condition with a consistent mesh tension across the screen.


6. Why are my prints smearing?

  • This may be caused because the prints have not been thoroughly cured.
  • Ensure the curing temperature and duration is correct.
  • Ensure the curing method has sufficient air flow and extraction to ensure all solvents are removed from the prints.
  • Consider increasing the curing temperature and/or duration for larger print designs.
  • Consider the use of ECOTRANS® SI Accelerator (80-AD-AC) to improve curing.


7. Why are my transfers wrinkled or distorted after the drying tunnel?

  • This may be caused because the PET film is not heat stable at the current curing temperature.
  • Consider using a PET film that is heat stable at the required curing temperature.
  • Consider using ECOTRANS® SI Accelerator (80-AD-AC) and reducing the curing temperature from 140°C to 120°C as indicated in the Usage When Curing Temperature of 140°C Cannot Be Attained section.


8. Why are my transfers not releasing from the release substrate?

  • Ensure the appropriate release substrate is used.
  • Check the release substrate is within its expiry date.
  • Confirm the release substrate has been printed on a side with a release coating if not double sided. 
  • Check both the inks and the additives are within shelf life and expiry dates.
  • Ensure the inks are fully cured before attempting to transfer.
  • Ensure a compatible adhesive is used. 
  • Ensure that the maximum temperature specified in the melting conditions has not be exceeded when using ECOTRANS® Hot Melt Powder Adhesives.
  • Ensure sufficient time has elapsed between printing the inks and adhesives and attempting to transfer. 
  • Ensure application temperature is correct. If the platen temperature is too low then the adhesive may not melt completely and therefore not be able to flow into the application substrate correctly. Be aware that the platen temperature can reduce after multiple transfer applications.
  • Ensure the platen pressure is correct. If the pressure is too low then the adhesive may not be pushed into the application substrate sufficiently to adhere and pull the printed heat transfer label from the release substrate. Please note that the inlet pressure does not equate to platen pressure.
  • Ensure the application dwell time is correct. If the dwell time is too short then the adhesive may not melt completely and therefore unable to flow into the application substrate.
  • Ensure the application instructions are followed for cold-peel or hot-peel release substrates.
  • Hot Peel release substrates can typically be removed 1-2 seconds after application.
  • Cold peel release substrates can typically be removed 10 seconds after application.


9. Why are my applied transfers not meeting the expected wash or durability performance?

  • This is often caused because the prints have not been thoroughly cured.
  • Ensure the curing temperature and duration is correct.
  • Ensure the curing method has sufficient air flow and extraction to ensure all solvents are removed from the prints.
  • Consider increasing the curing temperature and/or duration for larger print designs.
  • Confirm that crosslinker has been added to the inks at the specified percentage and mixed thoroughly. Adding excessive crosslinker can reduce the flexibility of the applied heat transfer labels therefore limiting stretch as well as potentially reducing wash & durability performance.
  • Check both the inks and the crosslinker are within shelf life and expiry dates.
  • Ensure crosslinker has not been added to the screen printable adhesives.
  • Ensure additives are not used in excess of the recommendations.
  • Ensure the applied transfers are given the required 24 hours after application before testing.
  • To improve colour fastness to rubbing and abrasion resistance, consider mixing the first printed layer with clear ink or if not possible, print a protective first layer of clear ink.
