摘要
激光打标技术是一种非接触、无污染、无磨损的标记工艺,可在材料表面留下永久性标记。Photoshop软件是一个图像处理与绘图软件,利用其广泛的编修与绘图工具,可以更有效地进行图片编辑工作。由于激光打标只能标刻高于某一灰度值(该灰度值在打标时可设定)的较深的颜色,没有渐变效果,所以要求所做的图像最好为纯黑纯白的图像。本文探讨了几种Photoshop图像处理方法,分别采用曲线工具、滤镜工具、位图模式将彩色图像处理成适合激光打标的纯黑纯白图像,激光打标出的图像效果良好,生动逼真。采用曲线工具调节后的人物清晰可辨;采用滤镜工具中的影印效果后人物轮廓清晰;采用绘图笔效果后的人物如素描;采用位图模式,将图像转变为疏密不同的点状,经过激光打标到金属名片上的人物图像栩栩如生。学生可以根据个人喜好采用不同的工具处理。
Laser marking is a non-contaet, non-polluting and non-wear marks technology, and can producing permanent mark on the material surfaee. Photoshop is an image processing and graphics software. Picture editing can be carried out more effectively with the help of its editing and drawing tools. As laser marking technology can only mark a certain gray value of darker colors, images have to be processed into black-white form. Several image processing methods using Photoshop software are discussed in this paper. Suitable black-white images are successfully completed with the help of curve tools, filters tool and the bitmap mode. Samples of the images printed by laser marking are in good quality. People images can be more clearer with the help of curves tool, and the character outlines look like sketch after using filter tools. Bitmap mode can transfer images into different point cloud, which are finally used to produced life-like pictures. Students can choose freely different processing tools according to their personal preferences.
