Ink samples of a certain area and thickness are placed in a sealed balance bottle. Under certain time and temperature conditions, the solvent on the surface of the sample evaporates.

5.8.5 Preparation of standard solvent curves
5.8.5.1 For each solvent, use a 10-knob microinjector to inject 1 standard solvent into the infusion bottle through the reverse stopper, then keep it in a constant temperature box at 80±1 degrees Celsius for 20 minutes and take it out. The next day, place it in a 50±1 degree Celsius oven for more than 20 hours. After taking it out, use a 1mL syringe through the reverse stopper to extract 0.2, 0.6, 0.8, and 1.0mL of gas from the top of the infusion bottle and inject it for testing. The standard peak area of each solvent with different injection amounts is obtained. 5.8.5.2 The injection volume of the standard solvent is calculated according to the formula (1): Wstandard = [(D×V1)/V2]×V3
Wherein: wstandard——injection volume of the standard solvent, mg; D——solvent density, g/mL;
V1——the volume of the standard solvent injected into the infusion bottle; V2——the capacity of the infusion bottle, mL;
V3——the volume of the standard sample entering the instrument, mL.
5.8.5.3 The area of each chromatographic peak obtained is used as the ordinate and the corresponding solvent injection volume W is used as the abscissa to prepare the standard solvent curve of the solvent.
5.8.6 Chromatographic conditions

Nitrogen 50mL/min, air 0.5kg/cm2, hydrogen 0.6kg/cm2. 5.8.7 Operation method and calculation
5.8.7.1 Prepare the sample according to the color test method in GB/T13217.1 Gravure plastic ink test method, and let it stand in the air for 2 hours after preparation. Cut the sample into four pieces with an area of 200 square centimeters or 5cm×10cm, immediately put it in an infusion bottle, plug it with a reverse stopper, and keep it in a constant temperature oven at 50±1 degrees Celsius for 30 minutes. 5.8.7.2 Take out the infusion bottle containing the sample, extract the gas of the sample in the bottle with a 1mL syringe, inject it into the chromatograph for testing, and obtain the peak area of each corresponding solvent in the sample. 5.8.7.3 According to the peak area of each solvent contained in the sample, find the content of the corresponding solvent (P) on the standard curve, and calculate the residual amount of each solvent according to formula (2). W sample = (P/S) X (V2/V1)
Wherein: W sample-residual amount of each solvent in the sample, mg/m2; P-actual milligrams of each solvent in the sample, mg; S-printed area, square centimeters;
V1 injection volume, mL;
V2-infusion bottle capacity, mL.
5.8.8 Results
The total residual solvent content of the sample is expressed as the sum of the arithmetic mean values of the measured values of each solvent for more than two times. 6. Inspection rules
