1. The air pressure required for the inkjet slotting machine to start up is generally between 6-8Kgf/cm2.

2. When the ink printing slotting machine adjusts the position of the paper feeder, the gap between the front door and the tailgate is 1-2 mm larger than the width of the cardboard.

In order to make the cardboard stack neatly, it is advisable to fall freely.

3. When the ink printing slotting machine adjusts the position of the paper feeder, the distance between the left and right baffles is slightly larger than the length of the production paperboard by 2-3 mm.

4. The gap between the paper feed roller and the paper feed roller of the ink printing slotting machine is 0.1~0.3mm smaller than the thickness of the paperboard.

5. When adjusting the joint depth between the upper knife and the lower sipe of the slotting knife, it should be controlled within the range of 1.5~2.0mm. In principle, the three layers can be smaller than the five layers.

6. In the maintenance of the die-cutting pad of the ink-printing slotting machine, the cutter depth is controlled to about 1.3~1.5mm during normal use, and the surface debris and burrs on the pad surface are removed in time.

7. The ideal range for pH value of ink is 8.5-9.2.

8. The thickness of the inkjet machine steel scraper is generally 0.15mm.

9. Flexographic printing pressure is generally between 10 N/cm2 and 50 N/cm.

10. The common specification for the flexo printing for carton printing is 3.94mm.

11. At present, the number of screen lines commonly used for printing corrugated boxes by flexographic printing is 40-80 lines/inch.

12. In general, the number of anilox rolls is 4-5 times the number of screens added to the print.

13. Flexible resin plates cannot reproduce dots below 5%.

14. The flexographic printing capacity is between 50 and 1 million impressions.

15. Laser engraved anilox technology enables the number of engraving lines to be as high as 1000 lines/in.

16. When the pH is lower than 8.2, the viscosity of the water-based ink will increase and the drying will increase.

17. The pH range of some special water-based inks is different from ordinary water-based inks. The pH of gold and silver inks is 7.5~8.0.

18. The general pH stabilizer is used to add 1~2% of the total ink volume every 30 to 40 minutes, or to add stabilizer to the circulating ink pump.

19. In ink printing, the amount of defoamer added is generally not more than 0.5%.

20. When adding surfactant to the ink, the addition ratio should not exceed 2%.
