The Automatic Drying Tester for ink is used to test ink's drying time. This tester consists of a rotating cylinder, a weight wheel and a touch screen. During operation, the rotating cylinder spins at a constant speed meanwhile, the weight wheel moves in line along the cylinder axis at a constant speed. Apply the sample on the parchment（film length is 30cm, then insert the parchment on the rotating cylinder. Move the weight wheel to the starting point（cylinder left）and set the needed time（from 5 hours to 20 hours）which goes over the whole distance（the length of cylinder. If the ink doesn't dry completely, then the weight wheel would leave a mark on the parchment's blank space untill the test is finished. Obtain the test results by counting the ink traces on the parchment and rotating the cylinder's working speed.
