Description:

HWYM-01：Printing ink is dark green under normal environment,printing ink changes to invisible after printing.Be observed with our IR testing tool.

HWYM-02：Printing ink is dark green under normal environment,printing ink changes to invisible after printing.Be observed with our IR testing tool.

HWYM-03：Printing ink is colorless under normal environment,printing ink changes to invisible after printing.Be observed with IR laser pen is green.

HWYM-04：Printing ink is colorless under normal environment,printing ink changes to invisible after printing.Be observed with IR laser pen is red.

HWYM-05：Printing ink is colorless under normal environment,printing ink changes to invisible after printing.Be observed with IR laser pen is yellow.

HWYM-06：Printing ink is colorless under normal environment,printing ink changes to invisible after printing.Be observed with IR laser pen is blue.

Explain:

When you order the product, please tell us your printing method,such as offset, silkscreen,gravure or letter press, drying method is UV drying or air drying, we will provide you matched ink according to your device. Details below is helped us to provide you correct ink for using.

Printing method, such as offset, silkscreen,gravure or letter press.

1、Drying method, air drying or UV drying.

2、Printing material, such as paper, PET or PVC.

3、What kind of anti-counterfeirt technology you want.

4、Producing ink depends on your request above.

Solution:

HWYM-01/HWYM-02

Solution1: The main specific is invisible after printing,we can not see it under the common environment, So we can printing some graphics or letters on the package of products or on the labels, of course these graphics or letters are not seen after printing, then we use special testing tool to check it, if the graphics or letters is there, the product is genuine, otherwise it’s fraud.

Soultion2：Printing special code, this code is not 1D or 2D barcode, it’s a dot code, can not be seen after printing, usually barcode reader or other device can not decode it, using our company matched device--- Identify pen can decode it.If genuine product, after decoding,product information can be spoken out by identify pen.

HWYM-03/HWYM-04/HWYM-05/HWYM-06

These products are also invisible but different with HWYM-01/HWYM-02, Specific about this kind of product is that they can give out different color light after excitation, such as red, green,blue,yellow etc., so we usually print a ink layer,then test it by special wavelength laser pen. If there is a ink layer, we can see a color dot when laser  pen shines it.
