Corrugated Box Pre-Press digital Proof Solutions

Inkjet print technology is applied in corrugated box pre-press proof and small batch multiple medias produce. It means universal adaptable of printing material, including e.g. E flute, 3 or 5 or 7 layers media thickness. Corrugated box printing proof and small batch multiple medias digital printing are required to finish standard CMYK 4 color and special color printing, and show printing colors and all kinds of color gradations and hues. So the requirement to media and ink subscribes the application of digital jet printer in corrugated box proof field. If digital jet print technology wants to do corrugated box proof and small batch multiple media produce, it has to solve the problems of printing density and ink gloss. Major technology problems are: successfully develop a set of digital printing equipment and digital ink, matched with proper color management RIP software, and meet the quality requirement of printing machine. The media universality and consistency, colors, gloss, saturation, hues showed on packing material by digital ink are required to be the same as printing ink. Also the environmental standards need to be the same. And it can enhance printing speed and format.

After many years’ research, in 2011, Jinan Juli Digital Technology Company successfully developed corrugated box digital printing proof and small batch multiple media produce solutions. Pre-press digital proof is same with the offset printing. The same rate is more than 95% compared to the offset printing. The technology parameters of this corrugated box digital proof and small batch multiple media produce system are as below:

1. Universal adaptability of boxes: corrugated box material, thickness 1mm-100mm.

2. High chase color accuracy: matched with professional color management RIP software, it can show color density and surpass printing machine ink’s color density. Color gamut can reach and surpass European printing gamut standards. Jet print color standards are (Compared to standard printing color): Averagely Delta E≤2.5, maximum is Delta E≤10. It can meet requirements of over 90% users.

3. Hardware equipment specifications: Width is 1600-2500mm, length is not limited. Operation cost is low, printing precision is high. Solve simulate printing screen dot technology. Screen dot shapes and sizes can be controlled by software. The precision is 30-100 grid lines.

4. Printing speed and stability: Highest print speed is 40m2/hour. Equipment operates steadily.

5. Digital ink: The quality of digital ink is the same as traditional printing ink. Color, brightness, screen dot, gloss are all the same as corrugated box used ink. It is convenient to print proof on digital jet printer. Also the ink is environment friendly (pass SGS authentication), no smell, no erosion, high color density, wide color gamut and batch consistency.

The technology solutions of corrugated box proof and small batch multiple media produce developed by Juli, matched with professional color management RIP software, forms a competitive product. The solution has huge advantages in the fields of color performance, color accuracy, screen dot, ink gloss, media adaptation, solution, operation convenience, producing cost, and print speed, compared to current UV jet print technology in the market. At present, it goes into domestic packaging market and gets good feedbacks from users.
