Réponse rapide : For UV ceramic inks, buyers usually get a better shortlist when they first decide whether the real bottleneck is decorative color cleanliness, balanced cure across white or colored systems, or a harder pigmented cure-through problem. In Longchang’s current product set, Photo-initiateur 907 is often the best first benchmark when the ceramic-ink program is highly appearance-sensitive and needs low yellowing with good pigment tolerance. Photoinitiateur BMS moves up when the buyer wants a more balanced route with surface cure, depth cure, and direct white or colored-system relevance. Photoinitiateur ITX deserves earlier review when the ink behaves like a heavier, darker, or more difficult ceramic decorative package rather than a relatively straightforward color-controlled job.
This page is intentionally narrower than the broader UV screen ink discussion and complements the older company article on UV ceramic ink monomer selection. That older ceramic-ink page is useful for resin and reactive-diluent context. This article focuses on the photoinitiator decision after the buyer already knows ceramic decoration is a real application branch and needs a deliberate cure package instead of generic UV-ink assumptions.
Shortlist: when each photoinitiator is the better fit
| Produit | Best fit | Pourquoi les acheteurs le présélectionnent | Main watchpoint |
|---|---|---|---|
| Photo-initiateur 907 | Decorative ceramic inks where low yellowing, cleaner color, and pigment tolerance are the first qualification pressures | Longchang positions 907 for coatings and inks, especially white or light-colored systems with strict color requirements. The current page also highlights low yellowing and good compatibility with pigmented systems. | It should be screened as an appearance-led route first, not assumed to be the only answer for every ceramic decorative job. |
| Photoinitiateur BMS | Screen or inkjet ceramic inks that need balanced surface and depth cure across white or colored systems | Longchang directly positions BMS for flexographic, screen, offset, and inkjet inks, says it delivers surface cure and depth cure with an amine synergist, and explicitly says it is effective in white titanium-dioxide systems and other colored systems. | Because the route depends on an amine synergist, buyers should treat BMS as a formulation strategy, not a context-free drop-in choice. |
| Photoinitiateur ITX | Heavier, darker, or more pigmented ceramic ink packages that are harder to cure through cleanly | Longchang directly supports ITX for thick films, pigmented systems, screen printing inks, and packaging printing inks, which makes it commercially useful when a ceramic decorative ink behaves more like a difficult thick-film cure problem. | ITX is usually stronger as a problem-solving route than as the only first sample when color cleanliness is the main concern. |
Why UV ceramic inks need a dedicated photoinitiator decision page
In practical buying work, ceramic decorative inks are often judged on more than whether the print simply dries. Buyers usually care about appearance stability, opacity or pigment burdenet reliable cure on rigid decorative parts. That makes the photoinitiator decision more specific than a generic UV-ink article suggests.
- Decorative appearance matters: cleaner whites, brighter colors, and lower yellowing pressure can affect acceptance quickly.
- Pigmented ceramic systems can be harder to cure: the real issue is often not whether the top feels dry, but whether the full decorative layer cures reliably enough for production.
- Screen and digital ceramic-print routes can behave differently: buyers often need a shortlist that matches the actual process window instead of a broad ink answer.
- Ceramic projects mix aesthetics with production pressure: cure speed, color quality, and formulation practicality all matter at the same time.
That is why a dedicated ceramic-ink photoinitiator page is commercially useful. The real question is not simply which photoinitiator works in UV ink. It is which route makes the most sense for the decorative ceramic job being qualified.
When 907 is the better fit
Photo-initiateur 907 deserves early attention when the ceramic-ink program is mainly being judged by appearance quality. Longchang’s current public page positions 907 for traditional coatings and inks and says it is particularly suitable for white or light-colored systems with strict color requirements because of its low-yellowing characteristics. The same page also says it has good tolerance toward pigmented systems and is frequently used in colored inks and coatings.
That makes 907 a strong first benchmark when ceramic tiles, decorative panels, rigid branded parts, or similar printed ceramic formats need cleaner color after cure instead of a yellow-shifted appearance. It is also useful when the team wants pigment tolerance without giving up the appearance standard too early in screening.
The practical limit is simple: 907 is strongest when the buyer’s first problem is color quality. If the project is being blocked more by difficult through-cure in a heavier or darker ceramic decorative package, another route may deserve earlier priority.
When BMS is the better fit
Photoinitiateur BMS moves up when the ceramic-ink job needs a more balanced process answer. Longchang describes BMS as a benzophenone-family Norrish type II photoinitiator that delivers high reactivity plus surface cure and depth cure when used with an amine synergist in UV and LED curable formulations.
The direct application wording is especially useful for ceramic decoration because Longchang explicitly lists screen printing inks, offset printing inks, and inkjet inks. The same page also says BMS is effective not only in transparent systems but also in white systems containing titanium dioxide and other colored systems, while also emphasizing low odor and minimal yellowing.
For buyers, that means BMS is often the most balanced route when the project sits between easy appearance-led screening and genuinely difficult pigmented cure problems. It is the shortlist option to review when you want more than a simple low-yellowing benchmark, but do not yet need the most problem-solving cure-through route.
When ITX is the better fit
Photoinitiateur ITX deserves earlier review when the decorative ceramic ink is genuinely harder to cure. Longchang directly supports ITX for thick films, pigmented systems, screen printing inks, and packaging printing inks. That public wording makes ITX commercially relevant whenever the ceramic job behaves more like a heavy-deposit, opacity-loaded, or darker-color curing problem.
This is especially helpful in ceramic decorative systems where a simpler appearance-led route may not fully reflect the real formulation difficulty. In those cases, ITX is not just another option on the list. It is the route that earns its place when the buyer needs better logic for difficult cure-through conditions.
Used correctly, ITX is not the default for every ceramic ink. It is the product to move forward when the job stops looking like a relatively clean decorative print and starts behaving like a harder thick-film technical package.
How buyers should choose between 907, BMS, and ITX
Choose 907 first if:
- the ceramic print is highly appearance-sensitive,
- white or light-colored systems need lower yellowing pressure,
- or the team wants a cleaner decorative-color benchmark before moving into harder pigmented packages.
Choose BMS first if:
- the project needs a balanced route across surface cure and depth cure,
- the decorative job runs through screen or inkjet ceramic-print workflows,
- or white and colored-system flexibility matters more than chasing only one narrow cure feature.
Choose ITX first if:
- the ceramic ink is darker, heavier, or more pigment-loaded,
- routine low-yellowing screening does not reflect the real cure-through difficulty,
- or the team expects a decorative deposit that behaves like a harder technical package.
Common mistakes to avoid
- Do not treat ceramic decorative selection as a generic ink decision. Ceramic work can combine appearance pressure with heavier pigmented cure demands, so a generic UV-ink answer is often too broad.
- Do not choose only by appearance. A cleaner-looking benchmark is useful, but some ceramic inks fail because the real issue is cure-through in a heavier decorative package.
- Do not assume every colored ceramic ink needs the hardest cure route. If the job is mainly appearance-sensitive, 907 or BMS may be the more rational first screen.
- Do not ignore process reality. Longchang’s current public product pages give more direct printing-process relevance for BMS and ITX than a generic decorative-ink explanation would suggest.

FAQ
Which photoinitiator is the best first benchmark for UV ceramic inks?
In Longchang’s current public product set, 907 is often the strongest first benchmark when decorative appearance and low yellowing are the main qualification pressures, while BMS is attractive for more balanced white or colored-system printing routes and ITX moves up when the ink package is harder to cure through.
Why is UV ceramic ink selection different from general UV-ink selection?
Because ceramic decorative projects often combine color and appearance pressure with heavier pigment burden and more practical cure-through risk than a simple generic UV-ink explanation shows.
When should BMS outrank 907?
BMS should move ahead when the buyer needs stronger surface-plus-depth cure logic, direct screen or inkjet relevance, and clearer public support for white and colored systems instead of mainly prioritizing low-yellowing appearance.
When should ITX enter the first sample round?
ITX should enter earlier when the ceramic decorative ink behaves like a darker, heavier, or more pigment-loaded curing problem rather than a relatively straightforward color-controlled print.
Next step
If your UV ceramic ink project is being slowed by decorative color cleanliness, pigmented-system cure difficulty, or uncertainty around the first sample route, start by deciding whether the real qualification issue is low-yellowing appearance, balanced white or colored-system cure, or a harder pigmented cure-through problem. Then compare 907, BMSet ITX against the actual ceramic decorative package instead of choosing by generic UV-ink wording alone.
