Commercial Workflow for Sealing Trials & Sample Approval
封护打样与色样确认的商业流程

封护打样与确认流程是纠纷防线。打样按 300–800 元/块收费或免收（计入后续合同预付款），且必须在客户方实际环境（朝向、光照、背景）制作 200×200 mm 样板，覆盖光泽与哑光两档。样板贴标签注明牌号、道次、膜厚与施工温湿度，客户签字后一分为二：客户与工方各存一块，作为交付比对与售后争议的仲裁基准。合同附"封护外观分级表"，写明光斑、流挂、颗粒的允许限度，并约定轻微橘皮在户外 5 m 视距下不判不合格。售后复护按年收费（工程价的 3–5%），含巡检与局部补涂，把一次性工程变成长期现金流。
The trial-and-approval workflow is the dispute firewall. Charge 300–800 RMB per sample panel (or waive it against the contract advance) and make it on site — 200×200 mm in the client's real light, orientation and backdrop, in gloss and matte variants. Label each panel with product, coats, DFT and application conditions; after the client signs, split the set so each side keeps one as the arbitration reference for handover and after-sales disputes. Attach a "seal appearance grading table" to the contract defining tolerance for shine patches, runs and grit, with mild orange peel acceptable beyond a 5 m outdoor viewing distance. Recoat service at 3–5% of contract value per year — inspection plus spot repair — turns a one-off job into recurring revenue.
