How do you increase viscosity of ink?

for increase viscosity – increase Dye/pigment % in ink for solvent and water based ink. For water based ink – increase dye/pigment % or glycerol %.2021-07-15

What is viscous ink?

In ink terminology, viscosity refers to the extent to which ink will resist flowing. The viscosity of an ink will depend on the printing process it is designed for, and the nature of the substrate to which it will adhere. An ink’s viscosity is a component of its body.

How does the flexographic printing process work?

How Does Flexographic Printing Work? Flexo printing employs an efficient technology that involves creating an image in relief on polymer image carriers such as plates and sleeves. These are wrapped around the cylinders, and the ink is transferred from a pan to the plate through an anilox roll.2021-02-02

What is the difference between water based and solvent based ink?

When water based inks are used in an ink jet printer, the result is a higher definition image. A drop of solvent based ink is composed of 35% pigment and 65% apolar solvents. A drop of water based ink, on the other hand, is composed of 33% pigment, 33% water and 33% non-toxic, water soluble polar solvents.

What type of ink is used in flexo printing?

Flexographic printing is done on paper, cardboard, or plastic film. Liquid inks with a low viscosity are used for printing. There are water-based inks, solvent, and ultraviolet (UV)-cured inks among them.

What is flexography printing most commonly used for?

Flexography has been widely used as a quick and economical way of applying simple designs and areas of colour to a wide variety of packaging materials, such as paper and plastic containers (including waxed-paper ones), corrugated-cardboard boxes, tape, envelopes, and metal foil.

How can you reduce the viscosity of ink?

If you decrease the temperature of the ink it will be more viscous. But, if its not possible to decrease the temperature you can try by adding Glycerol. However, the glycerol could react with your ink or at least increase the drying time.2019-07-04

How does letterpress printing work?

letterpress printing, also called Relief Printing, or Typographic Printing, in commercial printing, process by which many copies of an image are produced by repeated direct impression of an inked, raised surface against sheets or a continuous roll of paper.

What is the meaning of flexographic printing?

flexography, form of rotary printing in which ink is applied to various surfaces by means of flexible rubber (or other elastomeric) printing plates. The inks used in flexography dry quickly by evaporation and are safe for use on wrappers that come directly in contact with foods.

How are flexographic printing plates made?

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.2018-04-05

What type of items is flexography most suitable for printing on?

Flexography is a modern version of letterpress printing. This traditional method of printing can be used on almost any type of substrate, including corrugated cardboard, cellophane, plastic, label stock, fabric, and metallic film.2020-09-24

What is water based flexo ink?

Water based flexo inks have considerably high surface tension, typically the highest of all inks, making them popular for printing on highly absorbent substrates of heavy weights, like corrugated packaging materials. They are compatible for use with every type of elastomer sleeve.2020-12-02

What are the four types of ink?

Most color printers follow the CMYK (cyan, magenta, yellow, black) model. To make new colors and create an image, the printers will layer tiny dots of the four printer colors.2020-10-28

What type of ink is used in gravure printing?

However, product gravure uses both water- and solvent-based inks (GATF 1992b). The industry has used water-based inks successfully on medium-weight papers and on nonabsorbent substrates such as plastics, aluminum, and laminates (Tyszka 1993).2019-10-30

Where is flexo printing used?

Flexo printing is widely used in the converting industry for printing plastic materials for packaging and other end uses. For maximum efficiency, the flexo presses produce large rolls of material that are then slit down to their finished size on slitting machines.

Why is water based ink better?

Higher Quality Prints Because they sit deeper within the fabric, water-based inks are able to produce longer lasting prints with impeccable detail, with much more defined, sharper edges. This includes half-tones and more, making them the perfect choice for printing really intricate, detailed designs.2019-02-26

How does the flexographic printing plate influences print results?

These printing plates have a dot that is flat at the top rather than rounded, which leads to more constant and accurate print results.2016-03-07

How do you measure ink viscosity?

Vibrational Viscometer. Zhan cup is a cup-type viscosimeter that measures the viscosity of the ink by flowing a definite volume of ink through the cup. The time (seconds) required for the ink to flow through the cup defines the viscosity of the ink.2020-02-25

What does water based ink mean?

WATER-BASED INK IS AN INK MADE WITH WATER RATHER THAN PLASTIC OR PVC. WATER-BASED INKS CAN BE SPLIT INTO TWO MAIN INGREDIENTS, WATER AND PIGMENT. It serves as a great alternative to plastisol ink in many circumstances.
