Process Printing – Creating the color gamut from the subtractive model
July 22, 2020 | Daywey Chen
Process printing is the reproduction of the color gamut through a few ink colors. In flexography, the common process color used are Cyan, Magenta, Yellow and Key or black. It is commonly abbreviated as CMYK. The four colors are printed onto the substrate as dots with varying size, shape and spacing. The four layers of CMYK dots are combined to form an optical illusion that these tiny dots are blended into smooth tones by the human eye. This process is known as the halftone process. The CMYK process printing is a subtractive model...
How to communicate in color?
July 8, 2020 | Daywey Chen
Communication has enabled society to advance. To be able to commutate effectively and efficiently has separated humans from all other species on the planet. People commutate in text, in sound, in code, in pictures…etc. People commute in many different languages, English, Chinese, Spanish, Malaysian…etc., you name it. As a printing professional, how do we communicate in color? What is the common color language that enables us to be on the same page?
Drying V.S Curing
June 17, 2020 | Daywey Chen
Drying process applies or generates heat to evaporate the water or solvents in the ink, leaving the pigment behind on the substrate to provide color. The curing process is the process to solidify the ink from liquid to solid...

Drying is one of the most important factors in printing. You can print with great registration. You can print with great speed. At the end of the day, if the ink doesn’t dry, your end result wouldn’t come out good. There are many drying methodologies. In this article, we are going to explore one of the drying technologies, Infrared.
100% eco-friendly algae-based ink
May 26, 2020 | Daywey Chen
The definition of a 100% eco-friendly ink is that it can go down the sink without causing any environmental harm. When we mention eco-friendly inks or biodegradable ink such as vegetable ink, soy ink or water-based ink. The term vegetable, soy, and water make it sounds like you can safely dump the ink waste down the drain. Some may even think that it could be safely consumed. However, this is not the case. These, vegetable, soy and water-based ink are not 100% eco-friendly...

Looking into the Packaging Material Characteristics
April 7, 2020 | Daywey Chen
One of the main purposes of packaging is to communicate with the customer about the product. However, that’s not all, packaging serves great importance when it comes to functionality. By functionality, we mean the ability to keep the product away from external contamination, damages, humidity, temperature and light. To keep the product inside of the packaging from leaking out, for instance to keep the odor, liquid inside of the packaging. Often times, multiple layers of materials are laminated together to achieve the functionality required, as different packaging materials have different properties. Today we are going look into a few common packaging materials used on the market and their properties.
Do you have control over your ink viscosity?
February 25, 2020 | Daywey Chen
How important is it to have control over your ink viscosity? Ink viscosity affects how well your ink is able to transfer over from the anilox to the plate, and from the plate onto the printing substrate. It affects how well your ink will dry on the substrate. In general, your press production speed, and the quality of your print is highly correlated to the ink viscosity. In Flexographic, having a suitable ink viscosity makes all the difference.

Having control over your ink viscosity can easily get you USD77,568 of savings per year...see our calculation

According to TAPPI testing guide (Technical Association of the pulp and paper industry) when controlling the web tension, a general guideline is to apply 5% ~ 25% of the maximum web strength, and around 0.5 ~ 1 PLI/mil of thickness.
What’s the difference between SCADA and HMI?
March 25, 2019 | Daywey Chen
Industry 4.0 is about the connection and communication between machines and systems to ultimately reach decision making with the absence of a human. More and more data are gathered throughout the production process. The machines get smarter with the increasing amount of data to work with. As a result, the production process becomes more efficient and productive and less wasteful. The ideal situation is to form a network of these machines that are digitally connected with one another to create and share information that results in the full power of Industry 4.0
