本文介绍一种在纺织印染花样设计、处理工艺自动化中使用的彩色图象光电扫描分色装置,其作用是将人工设计的美术图案经光鼓扫描分色测量,将光信息转换成电信息,然后通过A/D转换成R、G、B三基色信息,输入计算机自动处理后成为符合印染工艺的实用分色图片。该装置在机械结构上采用滚珠轴承导轨、精密丝杆传动,同步信号由光栅编码器给出,扫描速度快,每分钟扫描面积达720×16毫米~2。扫描密度达625点/毫米~2,扫描精度高。该系统作为一个光机电有机结合的整体,是印染花样设计、分色处理工艺自动化的关键,其扩展应用的前景也很广阔。
This paper introduces a color image photoelectric scanning and color separation device used in textile printing and dyeing pattern design and processing automation. Its function is to measure artificially designed art patterns by photographic drum scanning and color separation, convert light information into electrical information, And then converted into R, G, B three-color information through A / D, enter the computer automatically processed into a practical color separation process in line with the printing and dyeing process. The device adopts ball bearing guideway on the mechanical structure, precision screw drive, synchronization signal is given by grating encoder, scanning speed, scanning area of 720 × 16 mm ~ 2 per minute. Scanning density of 625 points / mm ~ 2, high scanning accuracy. The system as a combination of optical mechanical and electrical integration of the printing and dyeing design, color separation process automation key to its expansion prospects are also very broad.
