How to choose Kingplast online Gravure Printing Machine and online Flexographic printing machine?

I. Kingplast Film blowing machine work with online Gravure Printing Machine

Advantages

1. High Print Quality: Gravure printing uses dot transfer technology, resulting in high color saturation, rich layers, and high image resolution, making it suitable for exquisite packaging (such as food and cosmetic bags).

2. Strong Ink Adhesion: Gravure printing uses high pressure, allowing the ink to penetrate deeply into the film surface. It is particularly suitable for non-polar materials such as PE and PP, and has excellent abrasion resistance.

Disadvantages

1. High Equipment Cost: Gravure platemaking is expensive (several thousand yuan per set of plate rollers), making it uneconomical for small-volume orders.

2. Poor Environmental Performance: Traditional gravure printing uses solvent-based inks, which emit high VOCs and require exhaust gas treatment equipment. While water-based gravure printing is environmentally friendly, it consumes a lot of energy for drying.

II.  Kingplast Film blowing machine work with online Flexographic Printing Machine

Advantages

1. Flexible printing : Flexographic platemaking costs are low (approximately 1/5 of gravure), making it suitable for high-variety, small-volume orders (such as customized packaging). 2. Environmentally Friendly: Flexographic printing plates support water-based and UV inks, have low VOC emissions, and comply with environmental regulations (such as EU REACH and US EPA standards), eliminating the need for complex exhaust gas treatment.

Disadvantages

1. Low Printing Precision: Flexographic plates use rubber or resin plates, resulting in higher dot gain and generally lower resolution. Fine details (such as hairlines and small text) are less expressive than gravure printing.

2. Ink Drying Speed Limitation: Water-based flexographic printing relies on hot air for drying, making it prone to "sticking" in high-humidity environments. Printing speeds typically range from 50-80 m/min, slightly lower than gravure printing.

3. Short Plate Lifespan: Resin plates have a print lifespan of approximately 1-3 million impressions, lower than gravure chrome-plated plates (over 10 million impressions). Long-term, high-volume production may result in higher overall costs.

Summary

Gravure printing machine : Preferred for high-volume, high-quality, and color-critical packaging (such as snack bags and laminated films), but incur high equipment investment and environmental costs.

Flexographic printing Machine: Suitable for small-batch, high-volume, and environmentally sensitive products (such as fresh produce bags and courier bags). It offers particular advantages when printing on films with large thickness fluctuations or non-polar materials.
