What pigments are in ink?

Inorganic pigments are classified according to their color and functional properties as white, colored, black, extenders, metallic, and miscellaneous pigments. Each of these classes finds use in ink. Titanium dioxide (TiO2) is the most powerful and popular white pigment.

What pigment is used in printing?

Certain pigments used in printing inks have chemical structures that utilize cyanide complexes. They are iron pigments based on ferro and ferric cyanides, such as potash blue or soda blue pigments. Under conditions that decompose the pigment, cyanide can be liberated.

What is percentage of pigment in printing ink?

Pigments are substances which give colour to inks. The pigment ratio in offset printing inks are in between 15 – 25 percent. Pigment ratio affects the light fastness of ink.

What are organic inks?

Organic ink is made of fruit or vegetable-based pigments, also called “lake pigments”. They are oil dispersible, which just means the color dye will blend in with your skin more naturally with little to no clumping.

Is dye or pigment ink better?

Pigment inks tend to be lighter in colour than dye they are more water-resistant while producing a truer solid black than dye. Es-pecially when the label is exposed to UV light for many months, the pigment ink holds its colour, quality and vibrancy better than dye.

Is ink a solute?

Ink is the solute & water is solvent. The solvent is typically water but the ink contains either alcohol or else some volatile liquid. However, Solute is a pigment or dye which provides color to your ink.

What is the difference between pigment and reactive printing?

In the pigment printing the inks effectively settle on the fibre and on cotton they are not significantly recognizable by touching, however the textile is definitely more nubby than in the case of reactive printing….Pigment printing.

What are pigment inks used for?

Definition of Pigment Ink Pigments are finely ground particles of color that are suspended in the liquid medium. Pigment Inks are slower-drying because the ink actually sits on top of the paper. Pigment inks are used for embossing.

Is pigment ink permanent on fabric?

For all accounts pigment inks appear to be 100% permanent when printing on fabric with no post treatment. The pigment particles are clinging to each other as well as the fabric.

What is the principle of pigment printing?

Printing are insoluble coloring matter mostly mineral origin have been used for the coloration of metal, stone, wood and textile material. Basic Principle of Pigment Printing: Pre-treatments.

What is the difference between organic and inorganic pigments?

Organic pigments are generally brighter and better in tonal quality compared to inorganic pigments. However, this color tends not to last. For long-lasting products, producers prefer inorganic pigments because they tend to hold their color better in the presence of light and heat than organic pigments.

Is Canon ink pigment or dye?

Canon® Inkjet Printers Cartridges beginning in PG are Pigment based and CL or CLI are Dye based.

How is pigment paste used to make ink?

With this formulation the pigment paste is ground using a three roll mill. This pigment paste is then formulated with the diluents and photo initiators shown in order to produce an ink. These are starting point formulations, some adjustment will be required in order to optimize these formulations for a specific application.

What are the properties of oligomers in ink?

Oligomers provide pigment wetting, dispersion, film toughness, scratch resistance, and adhesion. They are used at 60 – 80% of formulation. Some of the more common oligomers used and their properties are listed below.

How are SMA resins used in the ink industry?

SMA resins, acrylate oligomers, and acrylate monomers are all used in the ink industry for lithographic, flexographic and screen printinks. Cray Valley’s acrylate monomers and oligomers provide all necessary reactive ingredients yielding the higher quality flexographic, lithographic, and screen inks.

How are oligomers used in Cray Valley inks?

Oligomers Oligomers provide pigment wetting, dispersion, film toughness, scratch resistance, and adhesion. They are used at 60 – 80% of formulation. Some of the more common oligomers used and their properties are listed below.
