빠른 답변: buyers comparing 907, BMS, 그리고 ITX for UV glass and ceramic inks usually get a better shortlist when they separate three different first-screen jobs instead of treating all three as interchangeable rigid-ink photoinitiators. 포토이니시에이터 907 is often the cleaner first benchmark when the decorative ink has to protect color cleanliness, lower yellowing, and white or light-color appearance. 광개시제 BMS moves up when the buyer needs a stronger surface-cure plus depth-cure balance in white or colored systems, especially when the process window may extend toward UV-LED screening. 광개시제 ITX belongs earlier when the rigid-decorative job behaves more like a thicker, more heavily pigmented screen-ink cure-through problem than an appearance-first white-ink problem.
That is the commercially useful split. This page is not another general glass-ink or ceramic-ink article. It is a narrower buyer-decision page for teams that already know they are working in UV rigid decorative inks and now need to decide which of these three Longchang routes deserves the first sample round.
이 비교를 위한 별도의 페이지가 필요한 이유
Longchang already has live supporting pages for UV glass inks 및 UV ceramic inks. Those pages help buyers decide whether the application itself belongs in the shortlist. But after that, many buyers still reach a narrower question: should the first trial start with 907, BMS, or ITX?
That choice matters because glass and ceramic decorative inks often have to balance more than one KPI at the same time:
- 외모 민감도, especially in lighter colors or white decorative areas,
- surface cure versus through-cure in screen-style or thicker-film work,
- 색소 부담 in more opaque or denser decorative systems, and
- process flexibility when the plant may compare conventional UV and UV-LED routes.
General industry references also commonly frame UV glass and ceramic inks around decorative rigid-substrate printing where color, adhesion package design, and cure behavior all need practical screening. That industry framing is useful here, but the product-specific decision still has to stay anchored to Longchang-supported facts.
Quick comparison table: 907 vs BMS vs ITX
| 구매 요인 | 907 | BMS | ITX |
|---|---|---|---|
| 최적 첫 번째 적합 | White or light-color rigid decorative inks where low yellowing matters early | White or colored systems that need balanced surface cure and depth cure | Thicker or more heavily pigmented screen-ink style systems that need stronger cure-through logic |
| 구매자들이 왜 그것을 후보에 올리는가 | Longchang supports 907 for coatings and inks with low yellowing, high photosensitivity, and good pigment tolerance, especially in white paints and light-color systems | Longchang supports BMS for flexographic, screen, offset, and inkjet inks, with high reactivity, low odor, minimal yellowing, white-system suitability, and a balance of surface and depth cure with an amine synergist | Longchang supports ITX for thick-film and pigmented-system work, especially in screen and packaging-printing style UV inks where deeper cure pressure becomes more important |
| Where it becomes more useful | Appearance-first decorative rigid inks | Broader process window and balanced cure demands | Harder-to-cure pigmented films |
| Main caution | Not every rigid-ink job needs a low-yellowing benchmark first if cure-through is the real bottleneck | The Type II route should be screened as a formulation package rather than treated like a drop-in swap | It is not the cleanest first answer when appearance sensitivity or lower yellowing outranks heavier cure-through pressure |
907이 더 적합할 때
907 should move to the front when the glass or ceramic decorative ink will be judged heavily by clean color, lower yellowing, or a more appearance-sensitive white or light-color result. Longchang positions 907 as a highly effective UV photoinitiator with low yellowing and says it is suitable for coatings and inks, especially in white paints and light-colored systems. Longchang also supports 907 with high photosensitivity, good pigment tolerance, and good storage stability.
That makes 907 commercially useful when:
- the rigid decorative ink is white or lightly colored,
- the buyer wants a low-yellowing starting point before escalating into heavier cure-through routes,
- the system still needs credible pigment tolerance without losing appearance focus, and
- the job is closer to an appearance-sensitive decorative screen than to a very hard thick-film cure problem.
In practical terms, 907 is often the right first benchmark when the customer will notice color shift faster than they will notice the difference between two cure-through strategies.
When BMS is the better fit
BMS becomes more attractive when the buyer is not solving only for appearance, but also for a broader surface-cure plus depth-cure balance. Longchang positions BMS as a Norrish type II photoinitiator that provides high reactivity, surface cure, 그리고 depth cure with an amine synergist in UV and LED-curable formulations. The company page also places it in flexographic, screen, offset, and inkjet printing inks plus overprint varnishes, and explicitly supports white systems containing titanium dioxide and other colored systems with low odor 및 minimal yellowing.
That pushes BMS ahead when:
- the rigid decorative ink is white or colored and needs a more balanced cure profile,
- surface dry and through-cure both matter,
- the plant wants a practical route that can also support UV-LED screening logic, and
- the team needs a broader process tool than a simpler appearance-first benchmark.
For many rigid decorative programs, BMS is the cleaner middle route between 907’s appearance-led logic and ITX’s thicker pigmented-cure logic.
When ITX is the better fit
ITX belongs earlier when the real problem looks less like a light-color decorative decision and more like a harder pigmented cure-through or thicker-film screen-ink job. Longchang positions ITX strongly in screen printing inks, packaging printing inks, and other UV-curing systems where the formulary pressure is often heavier, darker, or less forgiving than a simpler white decorative benchmark.
That makes ITX the better first screen when:
- the glass or ceramic ink uses a heavier pigment burden,
- the print build is thicker and cure-through is the first worry,
- screen-printing logic matters more than low-yellowing appearance alone, and
- the job looks likely to punish a weaker thick-film route.
ITX is usually the better place to start when the buyer already suspects that an appearance-first route may cure too shallowly for the real decorative film build.
구매자는 샘플을 요청하기 전에 어떻게 후보를 압축해야 할까요
1. Start with the real commercial failure mode
If the customer will reject the job for color cleanliness, yellowing, or white appearance first, 907 deserves earlier review. If the panel still has to survive a broader cure-balance screen, BMS often belongs earlier. If the ink is thick or heavily pigmented, ITX moves forward fast.
2. Separate appearance pressure from cure-through pressure
Many teams waste time because they ask one photoinitiator to solve both at once without deciding which matters more in the first lab round.
3. Keep the print route visible
BMS and ITX both make practical sense in screen-style UV ink work, but BMS carries a stronger balanced cure and white-system story, while ITX fits the heavier pigmented route more naturally.
4. Do not ignore white-system reality
Longchang’s direct support for 907 in white or light-color systems and for BMS in titanium-dioxide-containing white systems is commercially useful, because many rigid decorative buyers start in exactly that decision lane.
5. Use sibling application pages for the next level of narrowing
If the project is clearly more about one substrate family than the other, move next into the dedicated glass-ink or ceramic-ink page rather than forcing this comparison to answer every application detail.

자주 묻는 질문
Which photoinitiator is best for white UV glass or ceramic inks?
There is no one universal answer, but 907 is often the cleaner first benchmark when the project is highly appearance-sensitive and lower yellowing matters early. BMS moves up when the white system also needs a stronger balanced surface-cure and depth-cure route.
When should buyers start with BMS instead of 907?
Start with BMS earlier when the project needs broader cure balance, white or colored-system flexibility, and possible UV-LED screening logic, rather than only an appearance-first low-yellowing benchmark.
When does ITX make more sense than the other two?
ITX makes more sense when the ink is thicker, more heavily pigmented, and more screen-printing oriented, so cure-through pressure becomes more important than lighter-color appearance logic.
Are 907, BMS, and ITX interchangeable in rigid decorative UV inks?
No. They can all belong in the same broad application family, but the current Longchang-supported roles are different enough that buyers should not treat them as plug-and-play substitutes.
Next step
If the rigid decorative job is mainly a low-yellowing white or light-color program, start by screening 907. If the project needs broader cure balance in white or colored systems, move BMS higher. If the line is behaving like a thicker pigmented screen-ink cure-through problem, put ITX into the first comparison set immediately.
