Solvent-based ink contains a dye made with liquid solvents. Mostly they are used for large format printing. In addition to this, there are still low-solvent and eco-solvent ink.

Components

The composition of the solvent ink includes solvents, which got its name. They represent organic solvents with aggressive action, film formers, pigments and polymers.

Part of this group of inks includes a substance called cyclohexanone, which constitute a danger to human health in the production of printed products and not fully neutralizing these properties for its operation.

In low-solvent inks, this substance replaced by other components, making them more expensive, but to operate them in areas with good ventilation.

solvent-based ink composition

The Most secure is considered eco - friendly and biosolvent ink.

With the help of solvent, exposure is performed on the surface of the material, causing its outer layer dissolves and the pigment is inside. Evaporation of the solvent is several seconds, while the dyes remain inside the material.

Characteristics

You Can give the following description of solvent ink. It dyes, which have a huge potential of resistance to abiotic influences of the environment and can be used for printing on a wide range of materials. Compared to solvent and low-solvent ink, eco-solvent resistance is somewhat lower.

History and present

Since its inception solvent ink passed 5 generations. The first dyes in its composition include methyl ethyl ketone, which was still more toxic than cyclohexanone, and a fire hazard. Gradually, the paint began to introduce esters of organic acids having a low molecular weight, which somewhat reduced the speed of drying of ink.

solvent ink

A New generation of ink began to form a film on the surface instead of penetrating deep. Printer manufacturers began to produce new heads for these dyes, because their viscosity was increased, which led to the deterioration of the heads.

Modern ink-generation V may not contain cyclohexanone, or to contain it to 5%. As solvents used are harmless esters of lactic acid.

Hard ink

Hard is also called solvent inks. They can be used only for materials that are intended for outdoor use, because in their composition are the most aggressive solvents. They can be used on such materials as paper, polymers, vinyl mesh, banner fabric with an opaque base.

Print-friendly solvent inks for interior purposes is unacceptable.

Working with them requires compliance with certain safety requirements, first of all, the means to protect the human body from chemical stimuli, and the availability of the means of ventilation of the premises.

The ink itself has an unpleasant odor, which is quite a long time stored in printed copies.

They are used in medium - and large-format prints when creating banners, posters, billboards, banners, transport advertising, and outdoor advertising.

solvent ink description

Soft ink

This type of ink is also called low-solvent. We apply a less aggressive solvents, which allows products made using these inks, to operate inside.

They are characterized by high adhesion and resistance to various abiotic factors.

They are used for making Wallpapers, banners, posters, stands and exhibition graphics.

It is Undesirable to use the materials produced using this ink, in terms of residential and office space.

At work you must also comply with safety requirements.

print friendly solvent inks

Eco-solvent ink

This type of ink is a solvent ink III generation. Here the pigments are particles of minimum size, the number of aggressive solvents is minimized. They can be used for interior, outdoor and indoor advertising.

Ink has a price that is much lower compared to low-solvent. Why the prefix "eco" in the title has a double meaning: it indicates that it is environmentally friendly ink, but at the same time that they are most cost effective.

These inks do not give unpleasant smell. Exhaust ventilation is not required, but preferably the room is well ventilated.

Unlike the previous types, these dyes do not penetrate deep into the material and fixed on its basis, which coloring layer is easily damaged.

Biosolvent ink

The Ink of the IV generation. They are marketed as completely safe, containing no harsh solvents.

There is absolutely no odor. Printing them does not require special protection measures.

Can be used to create materials that will be used in a residential home, office inside and outside.Production facilities do not need special equipment.

Printable solvent inks

printable solvent inks

Hard ink do not give the required quality of printing at high resolution. Most often they are used for plotters and printers, wide format (up to 5 m).

Low-solvent ink gives higher quality printing with resolution 720 DPI.

Using eco-solvent ink and biosolvent get photographic quality printing.

In conclusion

Solvent-based ink is passed in its development 5 generations. The print quality with each generation increases as damage dried ink. Improved the safety of the dyes. It is best to use eco - friendly or biosolvent ink.
