For flexo printing machine, it is very important to choose the right ink when printing, so what should be paid attention to when selecting the ink for flexo printing machine?
The inks used in flexo printing machine are usually called rotary inks. This ink is basically divided into the following two types: penetration drying type: due to the use of newsprint, offset printing, paper web offset printing press printing speed is higher, the ink The drying speed is fast, so most of the commonly used inks are penetration drying. Thermosetting inks: In modern commercial web offset presses, a drying device is added to the second half of the printing device. In order to adapt to this production, thermosetting inks are mostly used. This humor is heated in the drying device, and the solvent in the ink volatilizes so that the ink film can be dried quickly. The content of dry oil (such as sesame oil) in thermosetting ink is less, and the content of petroleum agent is more.
