解析 JDF 文档实现油墨预置技术的研究

目的实现CIP4油墨预置功能。方法通过Visual C++6.0平台,提取JDF文档中根结点下资源池结点"ResourcePool"中的墨区设置框架"InkZoneProfile"所包含的油墨预置信息。根据JDF文档的结构特点,采用定位关键信息、忽略次要信息的解析思路,通过实验得到网点面积率和墨键开度的关系,并运用最小二乘法建立拟合曲线。最后运用插值法将解析JDF文档获得的网点面积率转换为墨键开度值。结果实验证明该技术得到的墨区墨键值,只需要操作工人做微小的调整,即可得到满意的印刷成品。结论此项技术对于印刷效率的提高有极大的帮助。

Technique of Realizing Ink Key Presetting by Analyzing JDF Document

Objective To realize the function of CIP4 ink key presetting. Methods Visual C + + 6. 0 platform was used to extract the ink key presetting information from the ink zone settings framework of " InkZoneProfile" node in the JDF document root resource pool node " ResourcePool " . According to the structural feature of JDF document, a solution of ignoring minor message and positioning key information was adopted. The relationship of dot area ratio and ink key value was obtained by experiments and a fitting curve was established using least squares. Interpolation method was used to convert the dot area from the JDF document to ink key value. Results Experimental results showed that satisfactory printing product can be obtained after fine adjustment in the ink key value of ink zone obtained by this technique. Conclusion This technique is obviously beneficial for improving the printing capacity.
