What are oxidizing inks?

Definition of OXIDISING INKS: Inks that use the process of oxidation to dry. Oxidising inks absorb oxygen from the air; the oxygen reacts with substances in the vehicle (usually drying oils such as linseed oil), which causes the vehicle to undergo polymerisation and results in the ink hardening into a solid film.

What type of ink is used in offset printing?

What makes a good ink?

A synthetic or natural dye is dissolved in water and solvent* to give the ink its colour. The rendering of dye-based inks is brighter and less matt, due to better dispersion on the paper. As these inks diffuse little light, they enable richer, more vibrant and contrasting colours.

What are silver inks and pastes used for?

Our silver pastes are designed for flat-bed/rotary screen printing, syringe, ink-jet and high viscosity drop on demand. All materials exhibit excellent adhesion to a wide variety of substrates including TCO-coated glass, plastic films and Dycotec Materials’ own insulator products.

What’s the difference between ink and paste ink?

With paste, you may see a difference in consistency. Each color has its own unique formula, so paste consistency can vary. You will not experience a significant difference in ink consistency. However, paste is typically thicker than ink. Does ink dry more quickly or slowly?

Can you use paste and ink mixed together?

Paste and Ink mixed together, No. Do not heat set the paste. This means if you are heat setting a project with an iron, do not iron the paste.
