Watermark cardboard boxes are currently a popular packaging product in the paper packaging industry, widely used in many fields such as food, electronics, and agricultural products. In the production process, the following 20 sets of data are often used!
Common data for producing watermarked cardboard boxes
1. The air pressure required for starting the ink printing slotting machine is generally between 6-8Kgf/cm2.
2. When adjusting the position of the paper feeder in the ink printing slotting machine, the gap between the front door and the back panel is 1-2mm larger than the width of the cardboard, so that the cardboard can be neatly stacked and freely dropped.
3. When adjusting the position of the paper feeder in the ink printing slotting machine, the distance between the left and right baffles is slightly 2-3mm larger than the length of the produced cardboard.
4. The gap between the paper feeding wheel and the paper feeding roller of the ink printing slotting machine should be 0.1-0.3mm smaller than the thickness of the cardboard.
5. When adjusting the joint depth between the upper and lower grooves of the slotting cutter, it should be controlled within the range of 1.5-2.0mm. In principle, when making three layers, it can be smaller than five layers.
6. In terms of maintenance of the ink printing slotting machine's die-cutting rubber pad, the depth of the cutting blade should be controlled at around 1.3-1.5mm during normal use, and debris and burrs on the surface of the rubber pad should be removed in a timely manner.
7. The ideal range for ink pH is 8.5-9.2.
8. The thickness of the steel scraper for ink printing machines is generally chosen as 0.15mm.
9. The pressure for flexographic printing is generally between 10N/cm2 and 50N/cm.
10. The commonly used specification for flexible printing of cardboard boxes is 3.94mm.
11. At present, the commonly used number of screening cables for printing corrugated cardboard boxes using flexographic printing is 40-80 lines per inch.
12. Generally, the number of lines on the anilox roller is 4-5 times the number of lines added to the print.
13. The flexible resin version cannot reproduce dots below 5%.
14. The printing resistance of flexographic plates ranges from 500000 to 1 million prints.
15. The laser engraving mesh roller technology enables high-precision carving of up to 1000 lines per inch.
16. When the pH value is below 8.2, the viscosity of water-based ink will increase and drying will accelerate.
17. The pH range of some special water-based inks is different from that of ordinary water-based inks, with gold and silver inks having a pH value of 7.5 to 8.0.
18. The general usage of pH stabilizers is to add 1-2% of the total ink amount every 30-40 minutes and stir evenly, or add the stabilizer to the circulating ink pump.
19. In ink wash printing, the amount of defoamer added generally does not exceed 0.5%.
20. When adding surfactants to ink, the maximum addition ratio should not exceed 2%.
