Optimizing Performance and Quality: 4 Key Considerations for Water Based Flexo Ink

Water based flexo ink is a specialized ink designed for flexographic printing machine.

It is characterized by its environmentally friendly and safe composition, non-explosiveness, and absence of volatile organic compounds (VOCs).

water based flexo ink

Additionally, it exhibits excellent focus, strong water resistance, and fast drying properties, allowing for printing speeds of up to 150-450 meters per minute.

These qualities make flexo water-based ink particularly suitable for printing and packaging applications in industries such as food, medicine, cosmetics, and other areas with stringent hygienic requirements.

To ensure optimal utilization of flexo water-based ink, it is crucial to consider the following 4 key factors:


Fineness refers to the particle size of pigments and fillers present in the ink and serves as a physical measure of their dimensions.

Ink manufacturers control the fineness, and users need to be aware of this parameter.

The fineness of flexographic water-based ink generally ranges below 20μm, and it can be measured using a fine scraper.


Viscosity is a critical parameter for water-based ink, directly influencing the print quality.

Therefore, it is essential to strictly control the viscosity within a specific range.

Typically, the viscosity of water-based ink is maintained between 30-60 seconds/25°C, with the viscosity of 40-50 seconds (using a No. 4 cup).

High viscosity can adversely affect leveling properties and printing adaptability, leading to plate contamination and paste-like ink.

Conversely, low viscosity can impair the pigment’s dispersion and carrier performance.


If water-based ink is left unused for an extended period, certain unstable inks may settle or separate, while others may thicken.

Thorough stirring can resolve these issues naturally.

It is necessary to evenly stir fresh water-based ink before use, followed by appropriate dilution and adjustment.

Regular stirring of the ink fountain during normal printing is also recommended.

Water-based inks tend to freeze below 0°C.

If freezing occurs, the ink can be placed in a warm room to naturally dissolve and should be stirred thoroughly before use.

Viscosity is particularly sensitive to temperature variations, with higher temperatures leading to faster water evaporation and drying.

Consider reducing drying time or increasing machine speed in such cases.

Conversely, lower temperatures result in slower water evaporation and extended drying time.

Open the drying device or adjust the drying speed of water-based ink accordingly.

During winter usage, it is advisable to bring the water-based ink stored in the warehouse to the workshop in advance to allow for viscosity adjustment.


Drying is a crucial aspect of water-based ink and significantly impacts the quality of the printed output.

Operators should possess a comprehensive understanding of the drying principles to determine the appropriate drying time based on different products or substrates.

Adequate consideration should be given to mid-viscosity or pH stability to ensure optimal drying performance.

The drying process of water-based ink involves volatilization, absorption, and reaction solidification.

flexographic printing machine

Once completely dry, water-based ink exhibits strong water resistance and friction resistance.

If drying occurs too rapidly, the ink layer’s surface may peel off, and the ink may dry onto the printing plate.

This can result in unclear patterns, dirty plates, and the retention of internal water, leading to inaccurate printing.

These issues can be mitigated by using a blocking agent, increasing the printing speed, or adjusting the drying system.

When shutting down, it is advisable to clean the screen roller or ink fountain.

For shorter breaks, frequent stirring of the ink fountain is recommended to prevent surface skinning.

Conversely, if drying is too slow, paper expansion, reduced gloss, color folding printing issues, and potential sticking may arise, causing inconvenience for machine operators.

In such cases, it is advisable to verify the pH value and adjust it accordingly.

Adding an appropriate amount of stabilizer or ethanol can expedite the drying process of water-based ink.

pH Value

Water-based ink typically contains a certain amount of ammonium solution to enhance stability and post-print water resistance.

The pH value serves as an important indicator in this regard.

The initial pH value of water-based ink upon leaving the factory is generally around 9.

However, it should be flexibly controlled between 7.8 and 9.3, depending on different substrates and temperatures.

PH value

Simultaneously, it is crucial to consider the interplay between drying and viscosity and make adjustments by adding appropriate additives.

For gold ink, the pH value should not be excessively high; instead, it should be slightly alkaline, typically controlled within the range of 8-8.5.

Regular pH testing, approximately every 2-3 hours, is recommended to ensure the pH value remains within the optimal range for flexography printing suitability.

By considering these factors and following the appropriate guidelines, users can maximize the effectiveness and performance of water based flexo ink in their flexographic printing applications.

What is flexo printing process?

Flexographic printing, also known as flexo printing, is a popular printing process that utilizes a flexible printing plate to print onto a variety of substrates, including paper, plastic, film, and foil.

The process involves the use of a flexible printing plate made of rubber or photopolymer material, which is wrapped around a rotating cylinder.

As the cylinder rotates, ink is applied to the raised areas of the printing plate, which then transfers the ink to the substrate material as it passes through the printing press.

Flexo printing is commonly used in the packaging industry for printing labels, tags, and packaging materials such as bags, boxes, and cartons. It is also used in the production of newspapers, magazines, and other printed materials.

Flexo printing offers several advantages over other printing processes, including high-speed production, the ability to print on a variety of substrates, and the ability to use a wide range of inks, including water-based, solvent-based, and UV-curable inks.

what is offset printing?

Offset printing is a printing technique that uses a flat printing plate to transfer ink onto a rubber blanket, which then transfers the ink onto the substrate, such as paper or cardboard.

This technique is called “offset” because the ink is not directly transferred from the plate to the substrate, but is first transferred to an intermediary surface, the rubber blanket, before being transferred to the final substrate.

Offset printing is one of the most widely used printing techniques, especially for commercial printing.

It is ideal for high-volume printing jobs, as it is highly efficient and produces high-quality prints with sharp, clear images and text.

The offset printing process involves several steps.

First, the printing plate is created by applying an image or text onto a flat surface, typically made of aluminum or polyester.

The plate is then mounted onto a printing press, which contains a cylinder covered with a rubber blanket. Ink is applied to the printing plate, which transfers the ink to the rubber blanket.

The rubber blanket then transfers the ink onto the substrate, which is fed through the press.

Offset printing allows for precise color registration and a wide range of color options, making it ideal for printing high-quality marketing materials, such as brochures, catalogs, and posters. It can also be used to print on a variety of substrates, including paper, cardboard, plastics, and metal.

What is the difference between flexo and offset printing?

Flexographic printing and offset printing are two popular printing techniques that are widely used in the printing industry.

While both techniques have some similarities, they also have several key differences, including the following:

  1. Printing Plate: The primary difference between flexo and offset printing is the printing plate. In flexo printing, a flexible rubber or photopolymer plate is used, which is wrapped around a cylinder. In contrast, offset printing uses a metal plate that is mounted onto a printing press.
  2. Printing Surface: Another key difference between the two techniques is the printing surface. Flexo printing is primarily used for printing on non-porous surfaces, such as plastic films, foils, and metallic surfaces. On the other hand, offset printing is ideal for printing on porous surfaces, such as paper and cardboard.
  3. Ink: Flexo and offset printing also use different types of ink. Flexo printing uses fast-drying ink that is applied directly to the printing plate and then transferred to the substrate. In contrast, offset printing uses a wet ink that is transferred to a rubber blanket before being transferred to the substrate.
  4. Color Registration: Color registration is another significant difference between flexo and offset printing. Flexo printing requires precise color registration because the printing plates are wrapped around a cylinder, and any slight misalignment can cause blurring or distortion of the image. Offset printing, on the other hand, has a more precise color registration because the metal plates are mounted onto the printing press.
  5. Production Speed: Flexo printing is generally faster than offset printing, primarily due to the fact that the printing plates are mounted onto cylinders, which allows for high-speed production. In contrast, offset printing requires more setup time, which can slow down production.

Overall, both flexographic and offset printing techniques have their own strengths and weaknesses, and the choice between the two will depend on the specific printing needs of the project.

What is colour registration?

Color registration refers to the precise alignment of different colors in a printed image, such as in offset printing or other multi-color printing processes.

When printing an image with multiple colors, each color is printed separately, and the final image is produced by layering the colors on top of each other.

Color registration is essential to ensure that the different colors in the image align correctly and produce a clear and sharp image.

If the colors are not aligned correctly, the resulting image can appear blurry, fuzzy, or out of focus, which can detract from the quality of the print and render it unusable.

Achieving accurate color registration involves several steps, including preparing the printing plates or cylinders, setting up the printing press, and adjusting the ink and substrate.

The process requires careful attention to detail and precision, as even small errors in alignment can have a significant impact on the final image.

Color registration is critical for producing high-quality printed materials, such as magazines, brochures, and packaging, which often require precise and vibrant colors to stand out.

Skilled printers and printing equipment can achieve near-perfect color registration, ensuring that the final image is crisp, clear, and visually appealing.

What is a printing press?

A printing press is a machine used in the printing industry to produce printed materials such as books, newspapers, magazines, brochures, and other printed materials.

The primary function of a printing press is to transfer ink onto a substrate, such as paper or other materials, using a printing plate or cylinder.

Printing presses can use a variety of printing techniques, including offset printing, flexographic printing, letterpress printing, gravure printing, and digital printing.

Each printing technique has its own unique advantages and is suitable for specific types of printing jobs.

The basic components of a printing press include a feeding system that feeds the substrate into the press, a printing cylinder or plate that transfers ink onto the substrate, and a delivery system that collects the printed material.

Printing presses can be manual, semi-automatic, or fully automatic.

In manual presses, the operator manually feeds the substrate into the press and adjusts the printing cylinder or plate.

Semi-automatic presses use automated feeding and delivery systems but require manual adjustments.

Fully automatic presses are completely automated and can run continuously without manual intervention.

Printing presses have revolutionized the printing industry by making large-scale printing of high-quality materials possible.

They have enabled the mass production of books, newspapers, and other printed materials, making information more accessible and affordable to people all over the world.
