How do ODM manufacturers test the resistance of furniture to spilled ink?

ODM manufacturers rigorously test furniture resistance to spilled ink to ensure durability and customer satisfaction. The process typically involves applying standardized ink solutions to fabric or surface materials and observing absorption, staining, and ease of cleaning. Tests may include timed exposure, varying ink types (e.g., ballpoint, fountain pen), and multiple cleaning methods (wiping, washing, or chemical treatments). Manufacturers often follow industry standards like ISO or ASTM to evaluate colorfastness and material integrity post-exposure. Advanced labs may use spectrophotometers to measure stain retention quantitatively. High-performance furniture undergoes repeated testing to guarantee long-term resistance, a key selling point for commercial and residential use. Results inform material selection and protective coating development, ensuring products meet market demands for spill-proof durability.
