摘要
针对铝质气雾罐表面印刷图像随罐体扩冲而变形的问题,提出了一种解决图像变形的新方法,这种方法具有迅速、准确、稳定的特点。首先建立罐体的半径随高度变化的数学模型;其次用等步长插入或删除像素对原图像处理,得到预变形图像的基本算法。用图像预处理的改变量抵消由罐体扩冲变形而引起的变量,以满足忠实复制的印刷效果。该方法为后续的研究奠定了理论基础,对金属包装印刷品生产具有实际指导意义。
To solve the problem of the deformation of the surface printed image of the aluminum aerosol cans with the expanding of the can,a new method is proposed to solve the image morphing,which is fast,accurate and stable.Firstly,the mathematical model of the tank is established,with the equation of radius variation with height obtained;secondly,the original image is processed by inserting or deleting pixels with the equal step length,with the basic algorithm of image pre-deformation obtained.The change of image preprocessing is used to cancel the variable caused by the can expanding deformation to meet the printing effect of faithful reproduction.This method lays a theoretical foundation for the following research and is of practical significance to produce metal packaging and printing products.
