Problems solved by technology
[0003] However, the "YC / T207 Determination of Volatile Organic Compounds in Cigarette Rod and Packing Paper" method is only applicable to printed matter, and cannot be used directly for ink. Direct input of ink samples will often cause the detection equipment to be polluted by ink components and cause detection data to appear. deviation

Embodiment Construction
[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific examples.
[0029] The preparation method of ink sample provided by the invention comprises:
[0030] The ink is printed on the pretreated substrate by an ink sample making machine, and the printing thickness of the ink on the substrate is 15-50 μm;
[0031] drying the substrate printed with ink;
[0032] Add glycerol triacetate to the dried substrate, seal it and wait for testing.
[0033] As an embodiment of the present invention, the preparation method of gravure printing ink sample comprises:
[0034] 1. Pretreatment: Take 90g / m 2 Coated paper, cut into 130mm×650mm, put it in an oven at 125°C, take it out after 10 minutes, put it in an aluminum foil bag and keep it sealed to ensure that the VOC content of the coated paper is negligible.
[0035] 2. Sampling: Randomly take a b...

The invention discloses a printing ink sample and a manufacturing method of the printing ink sample. The manufacturing method of the printing ink sample comprises the steps that printing ink is printed on preprocessed printed materials through a printing ink sampling machine, and the printing thickness of the printing ink on the printed materials is 15-50 microns; the printed materials with the printing ink are dried; glycerol triacetate is added to the dried printed materials, and the printed materials are sealed to be detected. The manufacturing method of the printing ink sample is simple and convenient and easy to operate, and overcomes the defect that the content of the VOC of the printing ink cannot be directly detected. The printing ink sample obtained from the manufacturing method can be directly input detecting equipment and is used for precisely detecting the content of the VOC in the printing ink, and therefore the compositions of the printing ink can be effectively controlled, and the problems that the detecting equipment is polluted by the printing ink and errors occur to detection data cannot be caused.
Description
technical field [0001] The invention relates to the field of printing, in particular to an ink sample and a preparation method thereof. Background technique [0002] With the promotion of "green printing" in my country, especially the promulgation of the standard "HJ2503 Environmental Labeling Product Technical Requirements Printing Part One Offset Printing", it has pointed out the direction for the development of my country's printing enterprises. Taking cigarette pack printing enterprises as an example, the state In terms of safety and sanitation, the package printed matter promulgated industry standards such as "YC / T207 Determination of Volatile Organic Compounds in Cigarette Rod and Packing Paper". It can be seen that the state's control of the content of "volatile organic compounds (VOC)" in printed matter is a common trend in the development of the printing industry in the future. As a printing enterprise, in order to control the various substances of printed matter no...
