Although it&#;s a widely accepted fact that digital printing is the most cost-effective way to produce high-quality products, there are still times when you might need full-color printed materials that look and feel like they were printed on a press. 

If this sounds like something your business needs, then you&#;re in luck both flexo and gravure printing can give you exactly what you want! However, it&#;s important to understand how each method works before deciding which one is right for your project.

Gravure Printing

Gravure Printing

Gravure printing sometimes referred to as Rotogravure, is a long-run, fast, and high-quality printing technique. Gravure is an intaglio printing technique similar to engraving in that it creates delicate, detailed pictures. 

For CMYK printing, where each color of ink is applied by a separate cylinder with drying phases in between, it works effectively.

Gravure printing is a method of printing that is used to print on a variety of materials such as paper, plastic, metal, and glass.

Gravure machines are used to print the majority of the high-quality packaging labels in use today. These machines are capable of producing high resolutions on products ranging from food packaging to cosmetics. 

They work by using a gravure cylinder that has an engraved pattern with tiny ink channels called &#;grooves&#; or &#;rills&#; etched into its surface; these grooves hold up to ten times more ink than other types of printing presses. The ink is then transferred onto the substrate by pressure rolls that run along each side of these grooves (one side at a time).

Pros of Gravure Printing

  • Flexibility

A relatively wide range of colors can be printed on a gravure press and the quality is high, making it appropriate for short-run printing jobs. 

In comparison to flexo printing, which tends to not print as many colors at once and requires different screens depending on what is being printed (some colors are better suited), gravure offers better versatility in terms of its capabilities.

  • Durability:

Gravure is known for being extremely long-lasting and durable in terms of print quality it won&#;t fade or scratch off easily over time as some other methods do. 

This makes it ideal for products that need extra protection from environmental factors such as sunlight or heat/cold fluctuations so they&#;ll last longer without degradation in appearance or quality (e.g., outdoor signs).

  • Print quality

The equipment used in gravure printing produces consistent results, which means you can be sure that your print job will look great every time.

  • Easily reproducible 

This type of printing can be done quickly without having to worry about any errors occurring during production since there are no moving parts involved as there are with other methods such as screen printing which requires multiple steps before being able to produce copies of your design onto the paper stock.&#;

Cons of Gravure Printing

Although gravure printing is a great method for printing on smaller runs, the higher cost per unit and longer run lengths make it more expensive to get started. 

  • Expensive Solution: 

Gravure printers are more expensive than other types of printing. This means that if you&#;re looking for a low-cost solution, gravure probably isn&#;t the best option for you. However, if you want to create something that&#;s going to last for years and years, then gravure might be the ideal choice!

  • Gravure Printing takes Time and Planning:

The more time that goes into prepping your design and the more work that goes into printing it on your product, the better quality you&#;ll get from the final product. This means that if you don&#;t have much time or money (or both), then gravure might not be right for your business model!

  • Doesn&#;t work well with highly detailed images

Gravure printing doesn&#;t work well with highly detailed images because it creates small dots on the paper.

Flexo Printing

Flexo Printing

Flexo printing is a high-speed printing method that uses a printing plate and a rubber blanket to apply ink to paper. This method is used to print on packaging, labels, and other products. 

Flexo printing can be used with a variety of materials such as metal foils, plastic films, glassine papers, aluminum foils, and laminates. The main advantage of flexographic printing is its ability to print detailed images without any loss in quality.

The most common type of flexo presses is large-format offset presses which use metal plates instead of photopolymers plates like those used by gravure or lithography presses. 

However, if you don&#;t have access to one then there are smaller tabletop versions available that allow you to do small runs at home or at school!

The process begins with a digital image file that is used to create a negative form on the roller. The roller is then inked with a special ink that adheres to the surface of the roller, but not the grooves in between them. 

When this flexo roll is pressed against paper or another medium, it transfers its image onto the surface without any ink being deposited into the grooves where it would not show up on your final product!

Pros of Flexo Printing

  • Produces High-Quality Images:

Flexo printing produces high-quality images that can be reused multiple times without losing quality or clarity.

  • Less expensive:

Flexo printing is less expensive than other types of printing because it uses less ink per print run than other processes do (offset lithography requires more ink because it uses water-based plates instead of plastic ones).

  • Use Different Types of Substrates:

Flexo printing can be used on many different types of substrates (like cardboard or plastic), and it doesn&#;t require special materials like those used by letterpress machines (which use metal plates).

  • Great for Short Runs: 

If you only need a small number of printed materials, flexo printing may be better than other methods because it&#;s fast and efficient! Because there&#;s no setup time involved in this method (other than setting up your press), you can get more done faster than with other methods like offset lithography (OL).

  • Recycled Materials:

Because it doesn&#;t require any chemicals or solvents, flexo-printed products can be made using recycled materials like plastic bottles or cardboard boxes&#;which means less waste in landfills

Cons of Flexo Printing

  • Initial setup may require some time.

Flexographic printing requires a lengthy setup process. This is a result of the entire process being automated. Installing the material, setting the colors on the appropriate plates, using the appropriate plates to wrap the plate cylinders, and setting up the correct cutting die all need human labor. It could take some time.

  • Not Suitable for Heavy Stock Products

Flexographic printing is not suitable for heavy stock products since this type of paper can easily tear during the production process. In addition, using heavy stock paper can cause problems during drying as it may take longer for them to dry completely before they can be stacked for shipping purposes.

  • Flexography can be costly to use for small works.

Flexographic printing only truly makes sense when you&#;re performing a medium- to large-volume production since the plates used in this process are so robust. Additionally, bear in mind that you will need to submit a plate for each color if the task requires several colors.

Choose the Print Method that will Best Fit Your Needs.

Flexo printing is typically more cost-effective than gravure since it uses less ink to produce high-quality products. Flexo printing also has the added benefit of being more versatile than gravure because it can print on a variety of substrates and in different shapes and sizes.

When it comes to environmental friendliness, flexo printing has an edge over gravure as well: because flexo requires less ink, there&#;s less waste afterward; also, because the curing process for flexo doesn&#;t involve heat (as is true for gravures), there are fewer emissions associated with that part of the process. Flexo tends to last longer than gravures as well&#;in some cases up to 10 times longer! Finally, flexos tend to be more resistant than gravures when exposed to water or sunlight; they&#;re also more resistant against chemicals like acids or alkalis (i.e., cleaners).

FAQ&#;s

Q 1. What distinguishes flexo from rotogravure printing?

Comparing gravure and flexo printing in an image
Flexographic printing processes have irregular print quality restrictions due to poor consistency of print output, but rotogravure technology generates extraordinarily high-quality results quickly. While rotogravure is preferable for longer runs, flexographic printing is superior for short-run tasks.

Q 2. Can you still use gravure printing?

For the commercial manufacture of postcards, periodicals, newspapers, and corrugated cardboard, gravure printing is still commonly utilized (and other packaging materials). When work requires precise, detailed pictures in a fast, high-quality, and long-run printing process, rotogravure is used.

Q 3. Are offset and gravure the same thing?

In web offset, a printing plate is used; in gravure, an ink-carrying cell-encrusted cylinder is used. Gravure is an intaglio printing method, while web offset is an offset printing method (i.e. the cylinder comes into direct contact with the paper and is not offset). The heat from a gas oven dries web offset inks.

What Is Gravure Printing? Its Technology and Benefits

Gravure printing, also known as intaglio printing, is a high-quality printing technique widely used in the packaging industry. Renowned for its precision and consistency, gravure printing plays a pivotal role in producing premium designs for flexible packaging.

The process of gravure printing makes it possible to produce a concave pattern. The engraving of a picture or text on a printing cylinder does this. A water-based ink is applied to the surface of the printing cylinder at the time of printing, filling the ink in a hollow space in the cylinder.

The material will then go through the cylinder by this method: in transferring the ink stored in recessed areas to the surface of the material, which can be plastic film, paper or aluminum foil. This method ensures high-precision images and excellent print quality. It is considered extremely suitable for packaging printing projects that are in high volumes.

Advantages of Gravure Printing

The gravure printing performed with water-based inks renders themselves from every angle to excellent color depth and detail and any print results consistent that can withstand even high-volume production. The water-based ink has also excellent adhesion and abrasion resistance, making it the best choice for applications wherein the end product is flexible packaging and requires very high quality printings.

Longevity and Long Runs

Gravure printing machines are very robust and could run even for long periods without any compromise to print quality so that they become a good choice for mass production purposes. Such robust machines make gravure printing a preferred option for long term packaging production.

Versatility with Different Substrates

Gravure printing can handle a wide range of flexible packaging materials, including but not limited to plastic films, aluminum foils, and paper, and is equally suitable for food, label, and everyday item packaging.

Cost-effectiveness

Gravure is quite capital-intensive at purchase; however, it is cheaper than all the other methods, especially as it concerns high-volume production, and in so doing employs water-based inks. Such inks do save the environment and create cost reduction during use.

Difference Between Flexo and Gravure Printing

Gravure printing and flexo printing are both common methods of packaging printing, but they differ greatly in their processes and areas of application.

  • Print quality: Gravure printing offers higher image precision and color depth, making it particularly suitable for packages that require high-quality printing. While flexographic printing is highly adaptable, it is slightly less accurate and consistent than gravure printing in mass production.
  • Production efficiency: Gravure printing is suitable for mass production, especially in the long time, large-scale production runs show a strong advantage, while flexographic printing is suitable for smaller batches, diversified production needs.
  • Applicable materials: gravure printing can handle a variety of complex materials, including film, paper and composite materials, widely used in flexible packaging, while flexographic printing is more suitable for printing simpler materials.

Combining Gravure Printing with Water-based Inks

In addition to guaranteeing a great print result, gravure printing when combined with water-based inks becomes environmentally friendly.

Water-based inks decrease harmful solvent emissions and are the most significant part of environmental packaging.

Modern gravure printing machines provide companies with high-quality, environmentally friendly solutions for packaging printing&#;particularly when those companies want to produce high volume flexible packages-at higher productivity and environmental benefits.

The Future and Development of Gravure Printing

  • Technological innovation: Gravure printing presses are becoming increasingly intelligent and automated, greatly improving productivity while reducing operating costs.
  • Environmentally friendly: While water-based ink formulation is further optimized, gravure printing turns out to be a substantial method for companies to work towards sustainability.
  • Market expansion: Expansion within the gravure printing sector could be boosted by ever-pressing global demands toward efficiency and environmentally friendly forms of packaging.

Gravure Printing Press Pricing and Selection

Purchasing a gravure printing machineis a key to maintaining high quality production. There are multiple models of gravure printing machines available. Each price varies depending on the size, features, and capacity of the machine. To identify the most efficient gravure printing machine for mass production, it must be efficient but under budget limits, as this affects dramatically the cost of production and product quality.

Conclusion

Gravure printing remains the dominant technology in the packaging industry through its high quality printing results, excellent durability and productivity.

Combined with the use of water-based inks, it not only improves environmental friendliness, but also further consolidates the importance of gravure printing in flexible packaging.
