The user must check the positioning accuracy of the laser plotter before purchasing the laser plotter. Users should spend some time to test the positioning accuracy and retention of the photoplotter. The hardware indexes of laser photoplotter are mainly reflected in the following aspects: positioning accuracy, format, resolution, uniformity, optical system quality and reliability.

1. Resolution

The resolution of laser plotter refers to the density of scanning points during scanning imaging. The higher the resolution of the photo plotter, the greater the scanning density, the smaller the light spot, the smoother the line edge and the thinner the line drawn. The unit of resolution is DPI, that is, how many points can be arranged in an inch of length.

2. Positioning accuracy

Positioning accuracy is not only an important technical index in the hardware index of laser plotter, but also the most difficult technical index to achieve. Its subdivision can be divided into absolute positioning accuracy and relative positioning accuracy.

3. Reliability

Reliability is also the most concerned problem of users. Haochuang Haohao’s domestic laser photoplotter adopts all domestic components, which can carry out the splicing processing of large files, so as to solve the problem of large file processing and long-time processing; Capable of line width correction, linear error correction and other functions; Documents larger than the format of the photo printer can be disassembled into small documents. The period size is suitable for the format of the photo printer, and the films can be spliced after photo painting; Various D codes can be converted.

4. Convenience of software operation

For users, the friendly interface has the advantages of concise and clear prompts, simple operation, high efficiency and happy mood. Bad software operation is repeatedly converted, inefficient and error prone. Long term use makes people feel irritable.

Users can refer to this evaluation from the following aspects:

① Whether such data can be automatically converted;
② How many hotkeys are used in operation;
③ Whether it is necessary to switch between each screen repeatedly;
④ The number of manual intervention during operation;
⑤ Whether all operations are completed under the unified interface.
