Jawaban singkat: buyers choosing additives for gravure inks usually get a cleaner first shortlist when they separate three different problems early: poor substrate wetting, weak print-side leveling or slip balance, Dan persistent microfoam or air-release trouble. In Longchang’s current CHLUMICRYL® branch, CHLUMIWE® 2100 is the stronger first route when the gravure ink needs lower surface tension and better wetting on difficult substrates. CHLUMILE® 3432 deserves earlier review when the real bottleneck is smoothness, leveling, anti-adhesion, or slip on the print face. CHLUMIAF® 3062 moves up when the line is being slowed by foam, air entrainment, or process-side bubble defects in printing-ink or UV-ink work.
Halaman ini sengaja dibuat lebih spesifik daripada halaman yang lebih luas. Pelapis dan Aditif Tinta CHLUMICRYL® overview and different from the already-live function pages for aditif pembasah, aditif perata, Dan penghilang busa. The buyer question here is more application-specific: which additive route makes sense when the print line is gravure and the real commercial pressure is transfer quality, smooth laydown, film release, or foam stability on a fast web?
Why gravure inks deserve a separate additive-selection page
Longchang’s own gravure-printing guidance describes gravure ink as a low-viscosity printing system where transfer behavior, drying or curing stability, and final print quality have to stay in balance. Longchang’s company-controlled printing-ink application notes also separate surface wetting, smoothness, leveling, abrasion resistance, and defoaming as different additive jobs instead of treating them as one generic ink problem.
That matters because gravure buyers usually are not trying to solve a broad ink-additive question. They are often trying to answer a narrower production question such as:
- Will the ink wet film, foil, or another difficult substrate cleanly?
- Will the printed face level well without creating a new foam or compatibility problem?
- Will the ink block, stick, or scuff too easily after printing?
- Is microfoam or entrained air reducing print consistency on a fast line?
- Should the first additive screen focus on print-face control or process-side defoaming?
Those are practical B2B qualification questions, so a dedicated gravure page is justified.
Quick shortlist: when CHLUMIWE® 2100, CHLUMILE® 3432, or CHLUMIAF® 3062 usually makes sense
| Produk | Best first fit in gravure inks | Mengapa pembeli mempertimbangkannya | Titik pengawasan utama |
|---|---|---|---|
| CHLUMIWE® 2100 | Difficult-substrate wetting in solvent-based gravure and screen-printing inks | Longchang directly supports low surface tension, suitability for difficult-to-wet substrates, solvent-based gravure and screen-printing use, and no stable foam under high-speed dispersion at low dosage. | Use it when wetting is the real bottleneck, not as a substitute for a print-face slip or foam-control route. |
| CHLUMILE® 3432 | Print-face smoothness, leveling, slip, and anti-blocking in solvent-based gravure inks | Longchang directly supports ultra-smooth effect, improved substrate wetting and leveling, extremely low stable foam, excellent compatibility, anti-adhesion, anti-blocking, excellent slip, and suitability for solvent-based gravure inks. | Choose it when surface balance matters more than a dedicated process defoamer. |
| CHLUMIAF® 3062 | Printing-ink and UV-ink defoaming when foam or air release is limiting output | Longchang directly supports high compatibility, broad medium transfer, balanced defoaming and foam suppression, use in coatings, inks and UV inks, and no adverse effect on intercoat adhesion or recoating. | It is the stronger route when foam is the main defect, not when the first problem is substrate wetting or print-face slip. |
When CHLUMIWE® 2100 is the better fit
CHLUMIWE® 2100 deserves the first look when the gravure program is being limited by pembasahan substrat instead of by film smoothness or foam alone. Longchang supports it as a polyether-modified polydimethylsiloxane with very low surface tension. The current company page directly says it is suitable for difficult-to-wet substrates, suitable for solvent-based gravure printing ink and screen printing ink, and that with a small amount added it will not produce stable foam under high-speed dispersion.
That makes 2100 the cleaner first route when:
- film or foil coverage is unstable,
- the ink is pulling back or failing to spread evenly,
- the line is still running a solvent-based gravure architecture, and
- the buyer wants a wetting-first route before moving into broader surface tuning.
It is especially useful when the commercial risk is poor laydown on the substrate rather than poor release after printing.
When CHLUMILE® 3432 is the better fit
CHLUMILE® 3432 should move up when the gravure ink already wets reasonably well, but the printed face still needs smoother leveling, better slip, less sticking, or more stable surface feel. Longchang directly supports it for solvent-based gravure printing ink and silk-screen printing ink. The same page describes ultra-smooth effect, ditingkatkan substrate wetting and leveling, extremely low stable foaming, kompatibilitas yang sangat baik, anti-adhesi, anti-pemblokiran, Dan excellent slip.
That is commercially useful because many gravure buyers are not solving only coverage. They also care about how the printed face handles on rewinding, stacking, converting, or later contact. 3432 is the stronger route when the project needs one additive that helps the print face behave better instead of only lowering surface tension.
When CHLUMIAF® 3062 is the better fit
CHLUMIAF® 3062 becomes more important when the line is being slowed by microfoam, air entrainment, or poor defoaming discipline. Longchang positions it as a silicone-compound defoamer with high compatibility, broad transfer in various mediums, excellent instant defoaming, Dan long-lasting foam inhibition. The same page says it is suitable for coatings, inks, UV inks, and epoxy floor coatings, and notes that it has no adverse effect on intercoat adhesion and recoating.
That makes 3062 the cleaner first route when:
- the gravure line is already suffering from bubbles or foam-related print inconsistency,
- the buyer needs a broader printing-ink and UV-ink defoaming reference,
- the process window is being narrowed by air release rather than by substrate wetting, and
- the team wants a defoaming route that stays compatible with later coating or recoating work.
Where CHLUMIAG® 3501 and CHLUMIFE® 3482X can still matter
Some gravure buyers will also want secondary comparison points after the first shortlist. Longchang’s company-controlled printing-ink notes and related pages make that reasonable.
- CHLUMIAG® 3501 can matter when the screen shifts toward stronger anti-blocking, print-side release, and lower dynamic friction in printing inks, inkjet inks, screen inks, overprint varnishes, and solvent-side packaging coatings.
- CHLUMIFE® 3482X can matter when the buyer needs a stronger slip and wear-resistance route, with Longchang directly supporting water-based and UV systems, anti-sticking, anti-blocking, abrasion resistance, scratch resistance, and recoating suitability.
Those are useful follow-up routes, but they should not replace the first question of whether the gravure problem is really wetting, leveling, or foam.
How buyers should shortlist additives for gravure inks
1. Start with the real process bottleneck
If the ink does not wet the substrate cleanly, start with a wetting route like 2100. If the printed face is rough, sticky, or poorly leveled, move earlier to 3432. If the line is losing stability to foam, 3062 deserves earlier review.
2. Separate print-face control from process defoaming
A gravure ink can need both, but buyers lose time when they test a defoamer to solve a leveling problem or a slip additive to solve air release.
3. Keep the system boundary visible
Longchang’s supported routes do not all live in the same system window. 2100 and 3432 are especially clear solvent-side gravure routes, while 3062 is broader across coatings, inks, and UV inks.
4. Keep converting and downstream handling in scope
For gravure buyers, print quality alone is not enough. Blocking, sticking, slip, and later coating compatibility often affect whether the sample is commercially acceptable.
5. Jaga agar putaran sampel pertama ketat
One wetting route, one print-face leveling or slip route, and one defoaming route usually produce a cleaner answer than testing too many partially overlapping additives at once.

Which additive should I test first in gravure inks?
Test the additive that matches the real bottleneck first. For difficult substrate wetting, start with CHLUMIWE® 2100. For print-face leveling, slip, or anti-blocking, start with CHLUMILE® 3432. For foam-control trouble, start with CHLUMIAF® 3062.
Why is gravure-ink additive selection different from a general ink-additive page?
Because gravure buyers usually have to keep transfer quality, low-viscosity behavior, print-face smoothness, and process stability in balance on a fast line. That creates a more specific shortlist logic than a broad generic ink article.
When should I move from 2100 to 3432?
Move from 2100 to 3432 when the substrate is already wetting reasonably well and the real issue becomes leveling, slip, anti-adhesion, or anti-blocking on the printed face.
Can CHLUMIAF® 3062 be relevant if the system also needs later coating or recoating?
Yes. Longchang explicitly notes that 3062 has no adverse effect on intercoat adhesion and recoating, which is one reason it stays commercially useful in broader printing and coating workflows.
Need a tighter gravure-ink shortlist?
If your gravure ink project is being limited by poor wetting, rough print-face leveling, blocking, or persistent foam, define that bottleneck first and then compare only the most relevant CHLUMICRYL® routes. That usually gives a faster and cleaner buying decision than treating all ink additives as interchangeable.
