Stage Exploration on the Specification Characteristics of Self-Inking Seals
From a quantitative perspective,the stage-specific characteristics of ink-return seals were ex-amined and the feasibility of using these features as a basis for determining the formation time of ink-re-turn seals was also discussed.Auto CAD was employed to measure the length and angle of natural ink-back samples over a one-year period,while SPSS data processing software was used to analyze and process the measurement results.The study obtained information on the changing patterns and thresholds of specification characteristics within different time ranges.Through multiple experiments involving vari-ous individuals,it was observed that there was an overall increasing trend in variation values for specifi-cation features with longer sealing times.However,there was no direct proportional correlation between added value and sealing time intervals.Additionally,it was found that environmental and human factors significantly influenced measurement results for specification features.Consequently,by observing trends in specification characteristics of reinking seals,it is possible to determine their sealing time.
