In the printing industry, accurate color reproduction is the core requirement for quality. Particularly, the rendering of high-saturation spot colors directly affects the visual expressiveness of products and brand recognition. Many practitioners have a question: Can flexo printing machine 6 colour accurately reproduce high-saturation spot colors? The answer is a definite yes. Relying on advanced 6 color printing systems and precise color control technologies, 6-color flexo printing machines can not only easily handle high-saturation spot colors, but also unlock more possibilities for rich color expression.
I. What is a flexo printing machine 6 colour ?
A flexo printing machine 6 colour is a high-end model among flexographic printing equipment. Based on the core principle of flexography—relief printing—it engraves graphics and texts on flexible rubber or resin printing plates, precisely transfers ink via anilox rollers, and then applies appropriate pressure through impression rollers to transfer the ink on the plates onto the substrate surface to complete printing. Different from traditional 4-color (CMYK) printing machiees, it adds two special colors (such as light cyan, light magenta, or orange, green, etc.) on top of the basic four colors, forming a broader color gamut. It has stronger color control capabilities whether for direct spot color printing or spot color reproduction through multi-color overprinting. Its core advantage lies in breaking the color gamut limitations of 4-color printing through the coordination of six colors, making the reproduction of high-saturation and high-precision colors a reality.
II. Core Features of 6-Color Flexographic Printing machines
1.Precise Reproduction of High-Saturation Spot Colors
Unlike 4-color printing, 6-color flexo machines add two special colors, expanding the color gamut to cover over 90% of Pantone spot colors. For tricky high-saturation hues like red, orange, green, and purple, they deliver exact matches—color saturation and vividness outpace traditional equipment. Paired with high-precision anilox rollers, they maintain dot reproduction during high-speed printing, resulting in sharper, more three-dimensional color layers.
2.Efficient, Stable Production
flexograohic printing machine 6 color with full servo drive control keep registration errors within ±0.1mm for precise overprinting. Boasting a top speed of 500 meters per minute, they handle large-batch orders efficiently. Quick plate change tools, automatic tension control, and closed ink circulation systems cut downtime, boosting overall productivity.
3. Environmental Friendliness and Wide Adaptability It works with eco-friendly inks like water-based and UV-curable options, aligning with green printing trends. This meets strict environmental demands for food packaging, children’s products and similar fields. It also handles diverse substrates—paper, plastic films (BOPP, PET, PE), non-wovens, aluminum foil, etc.—enabling multi-purpose use.
4.Intelligent Operation for Greater Convenience
Equipped with an intelligent color management system, it supports multiple color standards, can automatically complete color correction and concentration adjustment, ensuring color consistency of batch printed products. Some high-end models are also equipped with a video inspection system, which can real-time monitor printing defects (such as stains, streaks, insufficient printing depth, etc.), greatly reducing the rejection rate.
III. Application Scenarios of Six Color Flexographic Printing Machine
With outstanding color performance, wide substrate adaptability and green printing advantages, six colour flexo printing machines have become core printing equipment in multiple industries, especially suitable for packaging printing needs in the food, medical and daily chemical fields, and can accurately match various commonly used printing materials such as film plastics, paper, aluminum foil and non-woven fabrics. The specific application scenarios are as follows:
1.Food Industry
As the core application scenario, it covers various food packaging such as plastic food bags, beverage labels, hamburger boxes, pizza boxes, etc. Food packaging has strict requirements on brand spot color reproduction accuracy and printing safety (environmental protection). The high-saturation color reproduction capability of 6-colour flexo machines can accurately match the brand visual image. Combined with environmentally friendly inks such as water-based inks and UV-curable inks, it can effectively avoid printing pollution risks, ensuring both printing quality and food safety meet standards, and is suitable for large-batch food packaging production needs.
2.Daily Chemical Industry
It covers flexible packaging printing of daily chemical products, such as tissue packaging, laundry bags, etc. Daily chemical products focus on brand visual appeal. 6-color flexo presses can accurately reproduce high-saturation spot colors and delicate color gradient effects of daily chemical brands, enhancing the high-end texture of product packaging.
3.Medical Industry
It meets various packaging printing needs in the medical industry, such as masks, medical aluminum foil, etc. Medical packaging has extremely high requirements on printing precision, environmental protection and functionality. The high-precision registration capability of 6 colour flexo printing machine can ensure that medical logos and text information are clear and error-free, and the adaptability of environmentally friendly inks complies with the safety standards of the medical industry.
4.Industrial and Commercial Printing
Such as woven bags, supermarket shopping bags, etc., which need to balance large-batch production efficiency and color recognition. The high efficiency and precise color control capability of 6-color flexo presses can easily meet these needs

CHCI-E-S Large CI Flexographic Printing Machine 6 Color
2. Central Impression Flexographic Printing Press (CI Type)：
Adopting CI structure design, all plate cylinders are arranged around the same impression cylinder. Substrates stay under stable tension during printing, boosting overprinting precision—ideal for thin plastic films and other stretch-prone materials. Its UV curing system dries ink instantly to prevent smudging, fitting high-end labels, flexible packaging and other high-precision needs. It accurately reproduces high-saturation spot colors and fine color layers.
3. Stack Flexo Printing Machine：
Adopting independent unit stacked layout, it has a compact structure, small floor space, and is easy to maintain and upgrade, and can easily achieve double-sided printing. Each printing unit can be independently adjusted, with extremely strong adaptability. It can not only complete conventional multi-color printing, but also flexibly switch to 6-color spot color printing to meet personalized spot color needs. It is suitable for scenarios such as small and medium-batch packaging printing, especially for production workshops with limited space.
