How to test the stability of cylinder printer ink?In addition to meeting various prescribed physical and chemical indexes,the stability of a good flatbed printer ink is also very important.When buying ink,do not blindly pursue cheapness,because cheap ink uses low-cost raw materials and low quality,resulting in different ink pigment particles,instability in the suspension system,and precipitation over time and temperature.The phenomenon of delamination will directly lead to the blockage of the print head of the flatbed printer,or even burn the print head and other serious consequences,so the flatbed printer should use good ink.
One.How to test the stability of cylinder printer ink?
1,light resistance test
The light fastness of uv machine printer ink depends on the light fastness of the selected pigment itself,it can be tested by QUV aging tester and X-Rite colorimeter.Because some printed items may be left outdoors for a long time,the screen will be affected by ultraviolet rays,acid and alkali,sand and dust and air pollution,so when choosing printing inks,try to choose the light fastness level 8(the high level is 8,due to the color The reason is that individual colors can only reach 7 grades)and weather resistance grade 5(highest grade 5)products.
2,high temperature test
After the cylinder printer ink is placed in a high temperature environment(55°C to 70°C)for a week,return to room temperature 20-25°C for 24 hours,and perform continuous printing test on the machine for no less than one hour.The ink is required to be continuous during continuous printing.,Does not change color.
3,low temperature test
After placing the cylindrical UV printer ink in a low temperature environment(-37°C to-46°C)for a week,return to room temperature 20-25°C for 24 hours,and perform continuous printing test on the machine for at least one hour.When continuous printing is required The ink keeps flowing and does not change color.
Two.Summary of the cylinder printer manufacturer Dacen
Ink is a consumable that is much consumed by flatbed printers,and it is also a basic factor in printing.Printing cannot be done without ink.The quality of the ink determines the quality of the printing effect and also affects the machine itself.A large part of the quality of ink is determined by stability.If the stability is poor,the quality of the ink must be poor.The above is the content of"How to test the stability of cylinder printer ink?",I hope to help you.
