Security holograms come with the thermo chromic ink that responds to the changes in the temperature. With the rise in temperature it becomes colorless from being colored and when the temperature falls it becomes colored from being colorless. Security hologram stickers are available with few other security inks like fluorescent ink, IR security inks, optical variable ink, sun light sensitive security ink etc.
Nowadays Scratch holograms are used more rather than the conventional grey latex scratch panel on the discount coupons; telephone top-up card etc. Holographic scratch off label has black lacquer as well as security cut. Nobody can check the information under the label and can remove label intact from surface. They have become quite popular in a very short span of time. But before you plan to buy make sure you approach the right firm.

Our main aim is to create most effective technology so as to help the Indian customer in recognizing the fake product in the market. In India are the most reliable hologram manufacturers. After going through various print based as well as optical technologies we initiated holography as key technology. We offer customized high security hologram and tampers evident label in several shapes, sizes and different color foils, moreover in customized foils with different thickness films. These tamper proof labels as well as tamper evident labels can only be supplied in the form of sheet and in roll form that can either be supplied manually or with the automatic labeling machine. We make the use of laser etching as well as thermal deposition for the trace and track of the holograms.
We also use flexographic printing which is UV based especially when the hologram has to be applied on the printing labels. We offer different kinds of products such as holographic pouches, holographic induction sealing wads, holographic shrink sleeves, security hologram, hologram stickers, scratch holograms etc.
