Use the actual printer output, media, ink or toner coverage, film, machine settings, and finishing sequence. The sample should include solid colors, fine type, photographs, and areas that may reveal haze or texture. Inspect it under the final display lighting and allow it to cool before judging the surface. Look for silvering, weak adhesion, color shift, curl, waves, edge lift, or uneven pressure across the width. If the laminated piece will be cut, creased, mounted, or folded, test those steps as well. Record temperature, speed, pressure, room conditions, and media details once the result is approved. This gives repeat jobs a dependable setup rather than requiring the operator to rebuild settings from memory.
