Preparation of Gold and Silver Inks
BOPP/PE Series (LP Code) – Preparation of "Green-Gold" (Yellowish-Gold) Ink
- Take a clean, empty container and pour in 10 kg of JR-LP-22 Transparent Yellow.
- Place it on a mixer and begin stirring, then add 2 kg of XL-10A silver paste. When adding the silver paste, incorporate it slowly and evenly in small amounts; do not add a large portion (such as a full scoop) all at once.
- After adding the silver paste, mix thoroughly for 5 minutes, maintaining a mixer speed between H30 and H40. Once fully mixed, filter the prepared ink before use. (This helps prevent the appearance of dark streaks when printing large areas.)
PET/BOPA Series (LA Code) – Preparation of "Green-Gold" (Yellowish-Gold) Ink
- Take a clean, empty container and pour in 10 kg of MG-DF-R4350 Transparent Yellow.
- Place it on a mixer and begin stirring, then add 2 kg of XL-10A silver paste. When adding the silver paste, incorporate it slowly and evenly in small amounts; do not add a large portion (such as a full scoop) all at once.
- After adding the silver paste, mix thoroughly for 5 minutes, maintaining a mixer speed between H30 and H40. Once fully mixed, filter the prepared ink before use. (This helps prevent the appearance of dark streaks when printing large areas.)
BOPP/PE Series (LP Code) – Preparation of Gold-Powder Ink
- Take a clean, empty container and pour in 10 kg of JR-LP Gold-Mixing Varnish.
- Place it on a mixer and begin stirring, then add 2 kg of "green-gold" (yellowish-gold) powder. When adding the gold powder, incorporate it slowly and evenly in small amounts; do not add a large portion (such as a full scoop) all at once.
- After adding the gold powder, mix thoroughly for 5 minutes, maintaining a mixer speed between H30 and H40. Once fully mixed, filter the prepared ink before use. (To prevent the appearance of faint streaks when printing large areas)
Note: The preparation method for LA-series gold-powder inks is the same as that for LP-series gold-powder inks; simply replace the JR-LP gold-ink mixing varnish with JR-LA gold-ink mixing varnish.
Preparation method for BOPP/PE-series (LP-code) silver inks
- Take a clean, empty container and pour in 10 kg of JR-LP gold-ink mixing varnish.
- Place it on a mixer and, while stirring, add 2 kg of XL-239 silver paste. When adding the silver paste, incorporate it slowly and evenly in small amounts; do not add a large portion (such as a full scoop) all at once.
- After adding the silver paste, mix thoroughly for 5 minutes, keeping the mixer speed between H30 and H40. Once fully mixed, filter the prepared ink before use. (To prevent the appearance of faint streaks when printing large areas)
Note: The preparation method for LA-series silver inks is the same as that for LP-series silver inks; simply replace the JR-LP gold-ink mixing varnish with JR-LA gold-ink mixing varnish.
Preparation of Pearlescent Inks
Preparation method for BOPP/PE-series (LP-code) pearlescent white ink
- Take a clean, empty container and pour in 10 kg of JR-LP gold-ink mixing varnish.
- Place it on a mixer and, while stirring, add 1.5 kg of "Ouke" (欧克) pearlescent powder (grade 1120#). When adding the pearlescent powder, incorporate it slowly and evenly in small amounts; do not add a large portion (such as a full scoop) all at once.
- After adding the pearlescent powder, mix thoroughly for 5 minutes, keeping the mixer speed between H20 and H30 (excessive mixing speed can damage the pearlescent effect). Once fully mixed, filter the prepared ink before use. (To prevent the appearance of dark streaks when printing over large areas)
Note: The preparation method for "LA" pearlescent white is the same as that for "LP" pearlescent white; simply replace the "JR LP" mixing varnish with "JR LA" mixing varnish.
"Interference Purple" (used for anti-counterfeiting on GBL products)
- Take a clean, empty container and pour in 10 kg of "JR LP" mixing varnish.
- Place it on a mixer and add 2.5 kg of "Ouke" (Ouke) Interference Purple powder. When adding the pearlescent powder, incorporate it slowly, in small, even amounts—do not add a full scoop at once.
- After adding the powder, mix thoroughly for 5 minutes, keeping the mixer speed between H20 and H30 (excessive speed will damage the pearlescent effect). Once thoroughly mixed, the prepared ink must be filtered before use. (To prevent the appearance of dark streaks when printing over large areas)
Preparation method for surface-print (JR) pearlescent white
- Take a clean, empty container and pour in 10 kg of "JR-8199D" high-temperature-resistant mixing varnish.
- Place it on a mixer and add 1.5 kg of "Ouke" pearlescent powder (1120#). When adding the pearlescent powder, incorporate it slowly, in small, even amounts—do not add a full scoop at once.
- After adding the powder, mix thoroughly for 5 minutes, keeping the mixer speed between H20 and H30 (excessive speed will damage the pearlescent effect). Once thoroughly mixed, the prepared ink must be filtered before use. (To prevent the appearance of dark streaks when printing large solid areas)
Preparation of Transparent Inks
Preparation method for PET/BOPA series (LA code) transparent inks (excluding transparent dark blue)
- Take a clean, empty container and pour in 10 kg of JRLA clear varnish (extender/binder);
- Place it on a mixer and begin stirring, then add 1 kg of dye-based colorant. When adding the colorant, introduce it slowly and evenly in small portions; do not add a full scoop at once;
- After adding the silver paste (metallic pigment), mix thoroughly for 5 minutes, maintaining a mixer speed between H30 and H40. Once fully mixed, filter the prepared ink before use. (This prevents printing plate clogging caused by undissolved dye particles.)
Note: The preparation method for benzene-free transparent inks is the same as that for LA transparent inks; simply replace the JRLA clear varnish with YZJ benzene-free clear varnish.
Preparation method for PET/BOPA series (LA code) transparent dark blue ink
- Take a clean, empty container and pour in 10 kg of JRLA clear varnish;
- Place it on a mixer and begin stirring, then add 0.5 kg of ethanol solvent;
- Add 0.6 kg to 0.7 kg of dye-based colorant. When adding the colorant, introduce it slowly and evenly in small portions; do not add a full scoop at once;
- After adding the colorant, mix thoroughly for 5 minutes, maintaining a mixer speed between H30 and H40. Then, add an appropriate amount (approximately 4 kg) of solvent and continue mixing for another 5 minutes. Once fully mixed, filter the prepared ink before use. (To prevent printing plate clogging caused by undissolved dye particles)
Note: The formulation method for benzene-free transparent deep-blue ink is the same as that for LA-series transparent deep-blue ink; simply replace the JR/LA-series mixing varnish (extender) with the YZJ-series benzene-free mixing varnish.
