Handwriting appraisal is mainly to identify whether the character was written by the person, not limited to signatures.
People who write have feelings, the same word, different moods, different temperatures, different locations, and what is written is different.
There is also such a feeling that this word is written by whoever wrote it at a glance!
How to identify it?
The "scavenger" in "Forensic Doctor Qin Ming - Scavenger" has to leave the word "scavenger" after committing the crime, but if you look closely at the "Dao" he wrote, there are three horizontal lines in "self". Therefore, a series of cases can be determined.
Qin Ming printed a lot of road accident handling books that he handled, and the Tao in these materials also has three horizontals from the inside.
This is the habit of writing.
Words can change, but habits are hard to change.
Handwriting is also based on writing habits.
Of course, there are also the rules of writing, the weight of the pen, smudging, and so on.
What do I need to prepare for handwriting identification?
Application. Materials to be identified.
More than three samples from the same period.
For judicial appraisal involved in court litigation, samples need to be cross-examined, and the appraisal agency only uses samples that are mutually acceptable.
