Embodiment 1

[0022] The detection steps of the present embodiment are as follows:

[0023] 1) After stripping the anti-counterfeit holographic direct-plating transfer paper, take a small piece of the non-aluminized paper, and use a saponin solution with a concentration of 1% to spray and clean the surface of the anti-counterfeit holographic direct-plating transfer paper until the cleaning is completed. 20-40 seconds is appropriate.

[0024] 2) After cleaning, use ionized water to rinse the saponin solution on the surface of the anti-counterfeit holographic direct-plating transfer paper until the rinse is complete, preferably for 10 to 30 seconds.

[0025] 3) Clean the surface of the anti-counterfeit holographic direct plating transfer paper with a concentration of 1% stannous chloride solution, and activate the active molecules. The activation time is preferably 20-40 seconds, and the paper is preferably not soaked.

[0026] 4) Use the silver mirror reaction method to silver-plate the sur...

Embodiment 2

[0034] The present embodiment is except that adopting concentration is 2.5% saponin solution, 1.5% tin protochloride solution, other is the same as embodiment 1.

Embodiment 3

[0036] The present embodiment is except that adopting concentration is 5% saponin solution, 2% tin protochloride solution, other is the same as embodiment 1.

[0037] The present invention is not limited to the above examples, and the above method is also applicable to the holographic transfer film. When testing the holographic transfer film, since the holographic transfer film will not be wetted by water, the activation time limit of active molecules can be extended appropriately.

Abstract

The invention relates to a method for detecting surface quality of carrier before aluminizing, which is characterized by comprising the following steps of: (1) cleaning: spraying and cleaning the surface of the carrier by using a saponin solution; (2) washing down: washing down the saponin solution on the surface of the carrier by using ionized water; (3) activating bioactive molecules: activating the bioactive molecules by using a stannous chloride solution to clean the surface of the carrier; (4) silver plating: plating silver on the surface of the carrier by using a silver mirror reaction method; (5) washing: washing the surface of the carrier by using ionized water; (6) drying: blowing and drying the surface moisture of the carrier; and (7) detecting. The detecting method has the advantages of simple process, convenient operation, small detection error and high efficiency. In the invention, a sliver layer is plated on the surface of a holographical transfer film or a piece of anti-fake holographical direct-plating transfer paper by using the silver mirror reaction method; and after the sliver layer is dried, a surface effect which is similar to an aluminized surface effect canbe obtained, therefore, quality testing staff are easy to find the problem of surface quality of the holographical transfer film or the anti-fake holographical direct-plating transfer paper, and the batch scrappage of aluminized finished products is greatly reduced and avoided.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting printing, and in particular relates to a method for detecting the surface quality of a carrier before aluminum plating. Background technique [0002] Transfer paper is an environmentally friendly packaging product that emerged in the 1990s. It is currently mainly used in the printing of cigarette packs and high-end wine boxes. The surface effect of transfer paper is a decisive factor affecting product quality. The process is to add holographic information to the BOPP original film after molding, and then to aluminize it, and then to peel off the original film after compounding with the original paper. Since the surface of the transfer paper is obtained by transferring the transfer film after molding, controlling the surface quality of the transfer film has become the most critical process step. At present, there is no uniform and clear detection method for the surface quality of the p...
