Visual printing refers to the presentation of the print. How well does the print come out visually in front of the audience? Does it serve its marketing purpose of appealing to the audience? On the other hand, functional printing is about the properties and functionalities delivered through the print. How well does it perform to carry out the actions that it is intended to? In this article, we will explore the differences between visual printing and functional printing from their applications and quality assessment methods. At the same time to discuss the scenarios and potential of combining visual printing and functional printing together.

So what is the opacity for the white ink laydown background? This is a common question that people ask when trying to identify the quality of the white ink laydown in Flexography. Opacity is definitely one of the metrics for measurement. However, it only tells part of the story. It is possible to have two prints with the same opacity reading but differs in print quality. The reason is that opacity alone does not measure the smoothness or uniformity of the ink laydown.

In any manufacturing process, a business evaluates cutting based on speed, accuracy, versatility, maintenance, and pricing. In general, laser die cutting is suitable for manufacturers that focus on short run orders with various customization requirements. The rotary die cutting is ideal for simple non-custom products in bulk. Let’s look into why that is so?

Coating is applied throughout the industry to enhance the performance of substrates. To enhance characteristics such as resistance to contaminates, durability, waterproof, conductivity, printability, downstream convertibility…etc. For optical films, coating is applied to enhance the performance of light transmission. To get the light to penetrate and to reflect off the substrate the way we wanted. To allow for a certain wavelength of light to pass through and for a certain wavelength of light to reflect off.

What is the right shape for my anilox? Well, this depends on what you want to print, plus various other factors like ink viscosity, ink density, ink particulates, and opacity requirements. The shape of your anilox cells will affect the amount of ink delivered to the substrate and its transfer stability.

Flexographic printing is one of the major printing processes adopted for packaging. The packaging across various industries such as food and beverages, FMCG, pharmaceutical, health, cosmetics, industrial, agriculture…etc. In this article, we will be exploring the 3 major substrates (materials) that are used in packaging including paper, metallic film, and plastic film.

Gearless Servo Flexographic press has become increasingly popular among the printing and packaging industry. A Servo Flexographic press is able to maintain print quality, reduce startup time and waste better. Many know that gearless servo presses are more precise when it comes to color registration and impression control when compared to a geared press. But why is it more precise? When is it more precise? Are there any other advantages besides being more precise? In this article we will compare the difference between a gearless servo press with a geared press.

The flexographic printing presses of today are a piece of high-tech machine. This includes equipping with technologies such as 100% inspection system, auto impression, auto registration, auto edge guide, NIR drying system, industry 4.0 data collection and analytics functions…etc. However, many printers are still using the most primitive way to control one of the most important factors in flexo printing: ink viscosity. When it comes to measuring the ink viscosity. Many printers have remained holding a Zahn cup in one hand and a stopwatch in the other. To depend on one’s visual to gauge the amount of time it takes for the ink to drain from the Zahn cup.
Why is an accurate ink viscosity crucial? How to effectively control the ink viscosity? The types of viscometers available to measure viscosity will be discussed.

Yes, when compared to solvent-based ink, water-based ink emits much fewer VOCs into the air making it more eco-friendly. However, this doesn’t mean that during production one can just wash up the ink waste and simply let it go down the drain. The wastewater from water-based ink contains pigments, dynes, vehicles, auxiliary solvents, and additives that are harmful to the environment. Water-based ink is better, but it is not perfect. The wastewater needs to be treated before it can be discharged. In this article, we are going to explore two different wastewater treatments used in practice which are chemical treatment and electrolysis treatment.

Flexo printing is about a combination of factors working together in harmony to reach an optimal printing result. To many, there are just too many factors to consider, making the process complicated and hard to master. For this reason, it has scared off many printers and converters in attempting flexo printing. Yes, there are many factors to consider. However, there is always a general rule of thumb. As long as one gets familiar with the rule of thumb and follows it through, one wouldn’t sway too far away from a decent flexo print. Today, we are going to discuss the general rule of thumb for printing solid versus printing highlights.

What is the definition of a perfect flexo plate? Well, this really depends on what you are going after? Are you going for the best possible image quality possible? Are you looking for the lowest cost plate? Are you looking to print images with lots of highlights? Are you looking to print images with lots of solid areas? A perfect flexo plate really depends on your requirements. In this article, we are going to look into the different metrics that you should consider when seeking and designing a flexo plate for your production. These metrics include 1. Line screen level 2. Flat top dots 3. Plate hardness 4. Plate duration 5. Micro Screening Plate 6. Plate surface tension.
