LITHOTRANS® LO Liquid Driers (10-AD-LD)

Use up to 5% if the ink dries too slow.

LITHOTRANS® LO Reducing Medium T (10-AD-RMT)

Use up to 10% to thin the ink as necessary.

LITHOTRANS® LO Retarder (10-AD-RE)

Use up to 3% if the ink dries too fast.

LITHOTRANS® LO Water Activated Driers (10-AD-WAD)

Use up to 3% if the ink dries too slow when printing small images or text.

Notes:

1. We recommend to only use the additives listed above to ensure the heat transfer labels produced with LITHOTRANS® inks and additives are STANDARD 100 by OEKO-TEX® Class 1 compliant.
2. We recommend not to use >10% of any combination of additives in LITHOTRANS® LO inks. 

None.

Release coated PET films

Release coated transfer papers

Notes:

1. Substrates to be printed must be tested for suitability with the LITHOTRANS® LO 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 LITHOTRANS® inks, additives and adhesives are STANDARD 100 by OEKO-TEX® Class 1 compliant. 

• The inks are supplied ready for printing.
• Once printing has been completed the printed substrate must be thoroughly dried for a minimum of 24 hours before additional processing.

Notes:

1. Ensure inks stored in part used containers are covered with greaseproof paper after usage to minimise ink drying and skinning. The greaseproof paper should be pressed firmly against the entire surface of the ink with any air bubbles removed.
2. LITHOTRANS® LO inks must be fully dried prior to screen printing ECOTRANS® AQ inks or ECOTRANS® AQ Screen Printable Adhesive.

• 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 the use of a humidifier / dehumidifier in the printing area to maintain the stability of transfer papers.
• We recommend the isopropyl alcohol concentration is increased to 20% for printing onto release coated PET films and transfer papers. This will lower the surface tension of the water giving the thinnest dampening on the plate possible to minimise over-emulsification. This is necessary because unlike paper and cardboard substrates, release coated PET films and transfer papers are not able to absorb excess water.
• Use IR drying in the sheet delivery area, if available, to accelerate oxidation drying.
• For best registration it is recommended that the substrate is conditioned to the ambient temperature and humidity of the print room prior to printing.
• Use a carton-grade anti-set-off powder to assist oxidation drying in the stack. 
• We recommend that ink is replenished into the ink duct in smaller quantities more frequently rather than larger quantities less often to prevent the ink skinning. This will improve production efficiency and reduce downtime as printing will not need to be stopped because of print defects.
• If printing is interrupted for more than 2 hours then remove the ink from the duct and clean the duct, rollers, plate and blanket with cleaning solvent approved by the press-manufacturer to avoid the ink hardening and becoming difficult to remove afterwards.
• Printed stacks should be stored in a temperature-controlled warehouse and not moved unnecessarily during oxidation drying to prevent marking/set-off.

• After printing is finished remove the ink from the ink duct.
• Clean the ink from the ink duct, ink rollers, plate and blanket with cleaning solvent approved by the press-manufacturer.

Notes:

1. Ink left on the machine will harden by the oxidation drying process and will be difficult to remove afterwards.
