　　The main problem in ceramic inkjet printing is the after-sale service, not only in after-sale service of the machine, but also the ink.

　　The service problem comes next after machine is installed. The service of ink concerns the fineness, color, quantity and degree of color development (dark or light) of ink and then comes the pattern service. For instance, you provide several patterns to users for reference and selection, or send free of charge some variety of designs, after the user make its selection, the technician of ink company will stay on the plant to assist the company in tuning the required color. Although the company will also send its relevant technicians for study, ink is after all a software keeping changing and new problems will occur.

　　Take simple ceramic wall tile as an example, it presently has three basic overglazed decoration effects, one is the mill finish transparent glaze, the second is floated milky glaze and the last one is the matt glaze. On the surface of these three different overglazed decoration effects, for same pattern, same color plotted by ink jet printer and fired in the same time, the resulted color and effect will be somewhat different, because their base are different. Moreover, other factors such as temperature change in kiln and alteration of glaze supplier (selection of transparent glaze supplier with lower price) will affect the color effect of the finished products.

　　INTESA will put on a new design of jet head product in Rimini Exhibition this October. The new design of jet head put on by INTESA for use on this type of machine can directly spray the printing ink prepared on roller printing machine, that is to say the commonly used color glaze on the market can be sprayed by it, so the cost can be greatly lowered.

　　陶瓷喷墨技术的问题主要是售后服务，但不仅仅是机器的售后服务，还有墨水。

　　机器安装好后，接着就是墨水的服务问题。 墨水的服务牵涉到墨水的细度、颜色数量多少、发色程度(深或浅)，然后就是图案服务。 比如提供一些图案供客户参考、选择，或者提供几幅免费赠送的花色，客户选定后，墨水公司的技术人员就会留在工厂帮企业调试出所需要的颜色。虽然期间企业也会派相应的技术人员来学习，但墨水是一个软件，跟硬件是有差别的，随时随地都在变化，都会产生新问题。

　　以相对简单的瓷片为例，瓷片目前有三种基本的釉面效果，一种是光面透明釉，二是浮浊白色釉，三是哑光釉。在这三种不同釉面效果的表面，用喷墨打印机绘制同样的图案，使用同样的颜色，并同时烧制，它所得到的颜色、效果均是不同的，因为它们本身的基础不同。此外，窑炉温度的变化，釉料公司(如选择价格更便宜的透明釉供应商)的更替，都会影响成品的颜色效果。

　　INTESA在今年10月的里米尼展会上推出一款新的喷头产品出来。这些喷头可以直接喷出用于辊筒印花机上的调制油墨，就是说目前市面上普遍使用的印花釉将可以直接拿来使用，如此一来成本可以降得非常低。
