What are the specific applications of Colorimeter in the ink industry?

色差仪应用的行业非常的广泛，即使说是各行各业也不为过，某一行业表面看起来和色差仪隔了千里万里，实际还是紧密相连，只要你与颜色打交道你就离不开色差仪，这大千世界到处都是色彩，怎么可能有行业离的开颜色管理，只是有些行业对色彩要求没有那么高而已。但是油墨行业不同，它对色差要求是很严格的，色彩的管理是不容马虎的。

有很多外部因素都可以造成油墨色差，油墨本身也存在一个同批色差和不同批次之间的色差问题，这是反映油墨质量的重要指标。但是对于油墨的颜色不能仅通过肉眼做出简单的判断，这就需要通过专门的颜色测量仪，即色差仪进行检测判断。一批印刷品更好使用同一批次的油墨（配制专色墨时更好一次足量调制），因为不同批的油墨中，有些油墨很难保证批次间油墨的色相没有差别。所以真的一批的油墨没有打印出所需的所有产品，就要在选定下一批时严格把关，用色差仪认真检测比对，选择数字颜色没有差距或差距很小的产品购入。

油墨质量的检测

我们应该要求油墨供应商提供相应的资料，更重要的是要对油墨的技术指标油墨颜色、着色力、粘度、耐光性、耐热性等进行检测。

油墨色相、着色力检测

色相、着色力是油墨检测的基本项目，它们对油墨的颜色影响很大。色相是油墨颜色的具体特征，在光学上对应于一定波长、频率的光，如：红、黄、蓝指的就是油墨的色相。同样色差仪检测原理也是通过检测这些并把颜色量化、数据化，是使用者更直观的了解色彩的变化。着色力是指一种油墨影响另一种油墨颜色变化程度的大小。调配专色墨时，当其中一种原墨的色相或着发生变化时，调出的专色墨颜色就会改变。在油墨的色相检测方面色差仪的重要性就是油墨日后打印出来效果的准定因素，所以在印刷商选择油墨是色差仪是很重要的，同样油墨的生产商也要靠色差仪来确保同款行的两批油墨没有色差。

色相的检测

For the newly provided ink, it is generally necessary to adjust its viscosity to the viscosity of the upper machine, use the printing machine to make a sample, print the color sample of the ink with a solid plate, or drop a few drops of the ink on the color development wheel with adjusted pressure, Drag it on the surface of the substrate with a certain pressure and speed, and display a ribbon as a color sample. A squeegee can also be used. Observe the effect of these proofs, if the ink layer is uniform and smooth, well-colored, with a certain gloss, the ink color is thick, and the color is basically the same as the standard Color Chart provided by the supplier (it can be provided by the ink factory), it means the hue of the ink meet the requirements. Finally, a certain amount of ink for this test can be sealed and stored as a reference wet color sample for the next hue test. The next time you buy the same type of ink as a sample comparison, you can’t just observe it with the naked eye. The observation with the naked eye has certain limitations. The color beyond a certain range cannot be seen by the naked eye, so using a Colorimeter will give more accurate results. to obtain the desired correct contrast value.

For the ink that has been used, you can adjust the viscosity of the ink to an appropriate value, use a color wheel to make a good sample, and compare it with the qualified color sample or standard color sample retained last time, and you can initially check whether the hue is consistent. Another method is to place a few drops of the wet color sample of the ink to be tested and the ink that passed the previous test on the color development wheel at a distance of about 1cm, and scrape them out side by side. At this time, two adjacent color bands will be left. By comparing these two color bands, you can more accurately judge whether the hue is the same.

In fact, there are still many applications of Colorimeters in the ink industry. This is just a little analysis of the influence of Colorimeters on ink hue detection. The impact is not ugly, but the poor instrument is a desired industry tool in the ink industry.
