近紅外光(Near Infrared,NIR)是介于可見光(VIS)和中紅外光(MIR)之間的電磁波,按ASTM(美國試驗和材料檢測協會)定義是指波長在780~2526nm范圍內的電磁波,習慣上又將近紅外區劃分為近紅外短波(780~1100nm)和近紅外長波(1100~2526nm)兩個區域。近紅外區域是人們最早發現的非可見光區域。

Near Infrared (NIR) is an electromagnetic wave between visible and middle infrared light. According to ASTM, it refers to the electromagnetic wave with a wavelength of 780 ~ 2526nm. Conventionally, near infrared region is divided into two regions: near infrared short wave (780~1100nm) and near infrared long wave (1100~2526nm). The near infrared region was the first non-visible region to be discovered.

紅外線吸收劑是近年來新興的一種添加劑,其應用范圍十分廣泛,其中十分重要的一項就是應用在防偽油墨中。近紅外吸收防偽油墨是通過把一種或幾種近紅外吸收材料加入到油墨中的方式制成。近紅外吸收劑通常是一種有機功能染料,它在近紅外區域有吸收,最大吸收波長700nm-1100nm,且震蕩波長落在近紅外區。添加了近紅外吸收材料的油墨可以吸收紅外線,如在印品的某一局部用這種油墨,在日光下無任何痕跡,但在檢測儀器下,可觀察到相應的信號或者暗紋。

Infrared absorber is a new additive in recent years, its application range is very wide, one of the most important application is used in anti-counterfeiting ink. we can get near-infrared absorption anti-counterfeiting ink by adding one or more nir absorbing materials into the ink. Nir absorber is an organic functional dye, which can absorb in the nir region. Its maximum absorption wavelength is 700nm-1100nm, and its oscillation wavelength falls in the near infrared region. The ink added infrared absorbing material can absorb infrared rays. If this ink is used on a part of the print, we can see nothing under daylight, but the corresponding signal or dark streak can be observed under the detector.

通常情況下,近紅外吸收材料是有機高分子材料,其在高溫下合成,生產加工工藝復雜,技術難度高,生產成本昂貴,因此近紅外吸收防偽油墨耐高溫、耐光照、性能穩定并且防偽效果好,仿造難度高。

In general, NIR is an organic functional dye. It is synthesized at high temperature, and its production and processing process is very complicated. It also has high technical difficulty level and production cost. Therefore, the infra-red fluorescent inks can withstand high temperature and long periods of light, it also has stable performance, good anti - counterfeiting effect, high imitation difficulty level.

紅外防偽油墨的優點眾多:防偽技術強,技術難度大,使用簡單,幾乎不受任何印刷條件的限制,可以印刷任何防偽圖案,而且可用任何印刷方式,適用于票據、證券、鈔票、商標等的防偽印刷。

The infra-red fluorescent inks has many advantages:it has strong anti-counterfeiting technology,  high technical difficulty level and can be easy to use.  It is almost free from any printing conditions. It can also be used for printing any security pattern. Besids, it can be printed in any way. And it is suitable for security printing , such as bills, securities, banknotes, trademarks, etc.

根據油墨對紅外線有不同吸收能力的特點,還可以匹配制成無吸收紅外防偽油墨和近紅外防偽油墨。無吸收紅外防偽油墨就是對近紅外線不具有吸收作用的印刷油墨。使用時可以由近紅外吸收油墨和無吸收紅外防偽油墨組成一對。將近紅外吸收防偽油墨印刷的防偽圖案或信息隱藏在無吸收紅外防偽油墨下,因此防偽功能更隱蔽,防復制功能更強,防偽效果也更好。

Because different inks have different absorption capacity of infrared, we can also make no absorption infrared anti-counterfeiting ink and near-infrared anti-counterfeiting ink. No absorption infrared anti-counterfeiting ink is a printing ink that does not absorb infrared rays. We can use the near infrared absorption ink and non - absorption infrared anti - counterfeiting ink into a pair. We can put near infrared absorption anti-counterfeiting ink printing anti-counterfeiting patterns or information hidden in the non-absorption infrared anti-counterfeiting ink, so anti-counterfeiting and anti-replication effect is better.

青島德達志成化工有限公司在以色列設有研發中心,依托耶路撒冷大學先進的實驗設備,經過多年的潛心研發,終于研制出了一款吸收峰狹窄且吸收率很高的新紅外線吸收劑---OMNISTAB NIR-788。

Deltachem(Qingdao) Co.,ltd has a R&D center in Israel which rely on the advanced experimental equipment of the university of Jerusalem. After many years of research, we finally developed a new infrared absorber with narrow absorption peak and high absorption rate ——OMNISTAB NIR-788.

歐穩德NIR-788是一種特別適用于防偽油墨的紅外線吸收劑,其自身的吸收范圍窄,且吸收效率高,在防偽過程中表現出高度的靈敏性。

OMNISTAB NIR-788 is a special infrared absorber used for anti - counterfeiting ink , its own absorption range is narrow and it has high absorption efficiency , it also shows high sensitivity in the anti - counterfeiting process.
