KINGCOLOR uses focused sample tests—including weight measurement, receipt printing and label application—to answer practical questions about product compatibility and performance.
Effective sample testing begins with the customer’s actual application question, rather than unnecessary complexity. This video shows paper sample weighing, thermal receipt output inspection and adhesive label application on a bottle.
Test results are observed and recorded, while confirmed samples provide a reference for subsequent production and repeat orders. KINGCOLOR selects test items according to the customer’s device, application surface and usage scenario to develop an appropriate product solution.
