What type of ink is used in flexography?
The two major types of fluid inks used in flexography are water-base and alcohol-base. Alcohol-base inks are most often used to print on nonabsorbent substrates such as film and foil. Water-base inks most often are used on absorbent substrates such as paper and paperboard.
Why is the flexographic ink so liquid?
The Reason Behind Water-Based Flexographic Ink Water-based acrylic polymers are used in inks every day, worldwide. This type of ink maximizes profitability while also reducing the impact our manufacturing process has on the environment. The most common diluent used is water.
What is minimum dot in flexo printing?
The information about minimum dot indicates what is the size of the minimum printing dot that appears on the plate. This size is normally expressed in microns (µm), or, less commonly, as a percentage of a given linescreen, and it is set as a threshold in plate imaging to obtain such size on the finished plate.
What is the halo effect in printing?
A letterpress and flexographic printing defect characterized by the accumulation of excess ink at the edges of printed letters and dots, and/or by a colored region surrounding the ink “piles” caused by excess spreading of the ink vehicle.
What is flexo coating?
So, let’s start from the beginning, what is a Flexographic coating unit? Well as the name says, it is an independent coating unit in the form of trolley which can be integrated into a Coater or Laminator and serve a similar purpose of a Flexographic printing deck which can be found in any Flexo printing press.
What is flexographic ink made of?
4 Common Types of Flexographic Inks Composed of prepolymers, monomers, photo initiators, and pigments. Dries and adheres only when exposed to UV light or electron beam.
What is flexo plate made of?
Originally, flexo plates were made from rubber, but are today made from photopolymer material in sheet form – which differentiates them from the fixed metallic printing plates of offset printing. The plates are flexible enough to be wrapped around cylindrical print/plate rollers.
What is a dot in printing?
It refers to ink dots appearing larger on the printed piece due to either a mechanical or optical effect. Dot gain is not good or bad. It is simply a normal result of the printing process that must be taken into consideration during the creation of the source file, the choice of papers, printing process, inks, etc.
What is dot gain in offset printing?
Dot gain, or tonal value increase, is a phenomenon in offset lithography and some other forms of printing which causes printed material to look darker than intended. It is caused by halftone dots growing in area between the original printing film and the final printed result.
What products use flexography?
Typical products printed using flexography include brown corrugated boxes, flexible packaging including retail and shopping bags, food and hygiene bags and sacks, milk and beverage cartons, flexible plastics, self-adhesive labels, disposable cups and containers, envelopes and wallpaper.
What kind of ink is used in flexo presses?
As previously mentioned, flexographic inks are divided into three main categories. Water-based inks are used on wide web flexo presses for applications like paper packaging, overwraps, bags, etc., and in narrow web flexo for products like pressure-sensitive labels, tags, envelopes and the like.
