Notes:

1. Substrates to be printed must be tested for suitability with the ECOTRANS® SB 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.
2. 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.

For use with ECOTRANS® SB Printable Adhesives 

• ECOTRANS® SB Purple Band Crosslinker (86-AD-PB) must be added to ECOTRANS® SB (86-OK-) inks at 8% and mixed thoroughly.
• The inks are now ready for printing.
• Each print layer must be thoroughly dried at a minimum of 125°C and for a minimum of 60 seconds to ensure completely dry before additional layers of inks are printed.
• Before printing the ECOTRANS® SB Printable Adhesives, ensure the drying temperature and duration is adjusted to meet the usage instructions of the adhesive.

For use with ECOTRANS® Hot Melt Powder Adhesives

• ECOTRANS® SB Purple Band Crosslinker (86-AD-PB) must be added to ECOTRANS® SB (86-OK-) inks at 8% and mixed thoroughly.
• The inks are now ready for printing.
• Each print layer must be thoroughly dried at a minimum of 125°C and for a minimum of 60 seconds to ensure completely dry before additional layers of inks are printed
• The final print layer must not be dried to allow the Hot Melt Powder to stick to the surface of the ink.
• Apply the Hot Melt Powder to the final print layer and remove excess.
• To melt the Hot Melt Powder, ensure the drying temperature and duration is adjusted to meet the usage instructions of the Hot Melt Powder. 

Notes:

1. ECOTRANS® SB (86-OK-) inks mixed with ECOTRANS® SB Purple Band Crosslinker (86-AD-PB) have a pot life of 4 hours.
2. Printed substrates must be allowed to cure for a minimum of 24 hours before application.
3. Wash & Durability Performance will be achieved 24 hours after curing. 

• The optimum print room temperature is 18-20°C.
• The optimum relative humidity is 50-60%.
• We recommend printing 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.
• The screen emulsion must be suitable for use with solvent based inks.
• For Mixing White (86-OK-1-1000) 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 solvent based inks.
• 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.
• We recommend to only mix the required quantity of ink and crosslinker to reduce wastage.

• Remove excess ink from squeegee and screen mesh immediately.
• Use PERFECTOS® Cleaner (99-10-56 / 99-10-S40) for final cleaning the of the squeegee and screen mesh to prevent ghosting.
• Ensure all ink is removed from the squeegee and screen mesh to avoid damage.

Notes:

1. The screen mesh must be cleaned thoroughly within 4 hours of when printing has stopped to avoid ink irreversibly hardening in the screen.

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

• This is often caused because the prints have not been thoroughly dried.
• Consider reducing the quantities of ECOTRANS® SB Retarder (86-AD-RE), ECOTRANS® SB Reducing Medium T (86-AD-RMT) and ECOTRANS® SB Slow Reducing Medium T (86-AD-SRMT) additives to reduce ink drying time.
• Ensure the drying temperature and duration is correct.
• Ensure the drying method has sufficient air flow and extraction to ensure all solvents are removed from the prints.
• Consider increasing the drying 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 reticulation?

• Reticulation can often be caused by a difference in surface tension between the ink and the substrate. The addition of ECOTRANS® SB Wetting Agent (86-AD-WA) may assist the surface tension of the ink to become compatible with the substrate.
• Confirm that no more than 1% of ECOTRANS® SB Wetting Agent (86-AD-WA) has been added to the inks.

3. 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.
• Mixing ECOTRANS® SB Purple Band Crosslinker (86-AD-PB) into ECOTRANS® SB inks can sometimes introduce air bubbles. These air bubbles can result in pin-holes appearing in prints. The addition of ECOTRANS® SB De-Foamer (86-AD-DF) can reduce this pin-hole effect.
• A low surface tension release coating can cause the pin-hole effect. The addition of ECOTRANS® SB Wetting Agent (86-AD-WA) may assist the surface tension of the ink to become compatible with the substrate.

4. 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® SB Retarder (86-AD-RE), ECOTRANS® SB Reducing Medium T (86-AD-RMT), ECOTRANS® SB Slow Reducing Medium T (86-AD-SRMT), ECOTRANS® SB Accelerator (86-AD-AC), ECOTRANS® SB De-Foamer (86-AD-DF) and ECOTRANS® SB Wetting Agent (86-AD-WA) 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.

5. 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.

6. 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 accross the screen.

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

• This may be caused because the PET film is not heat stable at the current drying temperature.
• Consider using a PET film that is heat stable at the required drying temperature.
• Consider reducing the drying temperature and increasing the duration if it is not possible to change the PET film.

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 drying conditions has not be exceeded when using ECOTRANS® AQ Printable Adhesives.
• Ensure that the maximum temperature specified in the drying conditions has not be exceeded when using ECOTRANS® SB Printable Adhesives.
• 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.
