2. the substrate is easy to fall off in the sample preparation process, so that the printed pattern is deviated;
3. the oil pump needs to be assembled during printing, the assembly is too complicated in the early stage, and meanwhile, the oil pump is stopped to be started too many times in the sample preparation process, the intermittent time is short, so that the oil pump is easily overheated, leaks oil and the like, and the oil pump is frequently replaced;
4. meanwhile, in the sample preparation process, unused ink printed on a silk screen cannot be recovered, so that raw materials are consumed.
