Product parameters

  printing substrate 
     

All kinds of paper such as black, white cardboard, leather-filled paper, and coated paper cannot be directly printed on the surface of metal, plastic, and film, but can be printed after primer. OPP matte film can also be matched with our special JT -1001 cross-linking agent is used, and its addition amount is 2-3%.

Printing method and related parameters
It varies according to the printing conditions, please consult us for details.

tolerance requirements
1. For wiping resistance to white electric oil, 1-2% cross-linking agent needs to be added to the touch oil JT-4090, which is limited to scraper and air knife coating.
2. The cross-linking agent needs to be added before printing, and it can be stirred manually for 3-5 minutes. Due to the limitation of the activation period, the touch oil JT-4090 added with the cross-linking agent needs to be used within 8 hours to ensure the best quality. cross-linking effect. If the temperature is below 15°C, it will not affect the effect; if the temperature is between 15°C and 25°C, it is recommended to use it up within one month; if the ambient temperature is above 25°C, the tactile oil with cross-linking agent has been added. JT-4090 can not be used after being placed for a long time, otherwise it will cause poor adhesion and white particles in friction; when the temperature is above 35 ℃, local or complete solidification and agglomeration will occur the next day.
3. The tactile oil JT-4090 has poor anti-sticking effect on face-to-face. It is recommended to add a cross-linking agent to completely prevent the sticking.
4. If double-sided printing is required, 1-2% of cross-linking agent must be added to prevent sticking. Double-sided printing cannot be done at one time. It is necessary to print one side first, and then print the other side after 24 hours.

wash
Since the water-based tactile oil JT-4090 is difficult to wash after drying, the roller must be kept in a dynamic state. If there is a shutdown, the roller should be cleaned immediately to prevent the tactile oil from drying on the roller and affecting re-printing. The detergent is usually water, such as If there is dryness, it can be washed with alcohol, and the washed product cannot leak back to the ink tank. When the machine is shut down for cleaning, the washing liquid cannot leak into the ink tank.
