Currently the most commonly used are the following four categories
Applicable temperature range of special ink for waterless printing
Ink temperature range
For the temperature range where water-free inks are used correctly, we take the temperature at which soiling occurs as the upper limit, and the temperature that is 5 ° C lower than the upper limit temperature is the lower limit. Excessive temperature is easy to appear dirty, too low will cause problems such as ink stacking, poor gloss, ghosting and poor ink. Therefore, it should be kept in the best range when printing.
Ink hardness and suitable temperature range
Ink hardness and suitable temperature range
The composition of water-free ink and ordinary water-based ink is not much different. Different from the emulsification characteristics of traditional water-based printing inks, water-free inks are easy to stick in the printing process, so it is necessary to control the ink hardness reasonably. This is mainly adjusted by controlling the temperature of the plate surface, and the use of tackifiers or debonding is assisted. Agent (the auxiliary agent of waterless printing ink is common to water ink).
Ink constant temperature control device in waterless printing
Ink thermostat
As mentioned above, in order to maintain the ink to be printed within a stable range of conditions, a constant temperature device should be added to the printing unit. Each printing unit has three hollow ink rollers, and cooling oil circulates in this channel to reduce the ink temperature and control the ink viscosity. The two devices in the above figure are real shots of the dedicated ink thermostat.
This is a good machine for making twisted paper ropes in roll, you can use the twisted ropes to wrap the gifts or for craft products, Paper Handle after knotted or tipped at the two ends or you can use it on the paper handle making to make different paper handles. It is running stably and fast and the rope diameters can be different and adjustable and customized according to customers` request. The rope can be made in different ways by using one paper roll, 2 rolls or more, which depends on the rope tightness, strongness, roundness and colors
