研究目的
Investigating the influence of cylinder pressure on the hue variation of ceramic tiles decorated by the laser engraving silicone cylinder method.
研究成果
The height of the cylinder affects very little the final tonality of the decorated tile, with recommended heights between 6.5 and 6.0mm depending on the incision and tone range. The study highlights the need to balance benefits against cylinder wear.
研究不足
The study found that cylinder pressure has little influence on the final tonality of the decorated design, with benefits needing to be balanced against increased cylinder wear.
1：Experimental Design and Method Selection:
The study focused on the pressure variable applied to decoration by silicone cylinders, with variations in height between the cylinder and the tile. Reflectance, shape, and filling of decorated dots at gray scale values of 5%, 25%, and 85% were analyzed.
2：Sample Selection and Data Sources:
Ceramic tiles were used, with fixed process variables including ink formulation, type of coating, and silicone cylinder characteristics.
3：List of Experimental Equipment and Materials:
Optical microscopy with Zeiss model Axio Scope A1, spectrophotometer model RS232C SPECTRAMAGIC MARCA KONICA MINOLTA, and Rotocolor S5 Universal? equipment were used.
4：Experimental Procedures and Operational Workflow:
Tiles were heated to stabilize temperature, received a water cover for moisture correction, and were then decorated. The working height of the silicone cylinder was varied.
5：Data Analysis Methods:
Reflectance and coverage area were analyzed using optical microscopy and spectrophotometry.
