[UV Ink Curing] Basic Way to Determine UV Ink Curing

1. Check the adhesion of the ink after the stacking of the printed product or wound. Similarly, the printed product printed with UV ink, if it is not solidified, will also cause this problem. So you can use this method to determine the curing effect of ink. 2. The method of pressing the thumb pressing method is the most convenient and fastest test method. The basic process is to use the thumb to press the curved surface on the surface, and then squeeze back and forth many times. , And ink marks on the surface of the thumb, it means that the ink is not well -curing. 3. The method of nail testing method is similar to the thumb press method. The basic basis is that the UV ink starts from the surface and gradually enters the internal. If the ink is not completely solidified, it will occur after the nail scratching, and the completely solid UV ink will not be scratched, so as to determine whether the ink has been solidified. 4. Tape stripping test Since the current UV ink is widely used in thin film materials or non -absorbing marks (such as aluminum -plated paper), the tape test method is applied to the test ink binding force performance performance. Considering that if the UV ink is not completely solidified, it will cause the ink and printing materials to be worse. Then after tape test, the ink will be peeled off by the tape from the surface of the print. The amount of ink peeling is related to tape models, peeling speed, and ink solidification. 5. Chemical testing methods. Many end users use printed ink anticated chemical solvents (alcohol) performance as an important aspect of evaluating product printing performance. Completely solidified UV ink has good antimrediented solvents, and the anti -chemical solvent performance of the undisclosed UV ink is poor. Because the UV ink with inadequate curing will appear a rigid surface, and in fact, the ink layer is still not solidified, it is soft, so the anti -chemical solvent is poor. In addition, acetone is also very suitable for testing the degree of solidification of UV inks. The method is to wipe it on the coating with a cloth with acetone. 6. Other methods The German Printing Association (FOGRA) recommends some testing devices to check the ability of UV ink to stripping and bonding into blocks. It can be tested in accordance with the methods provided by German industrial standards DIN16524 and DIN16525. More information is welcome to log in
