Paper Substrates Different paper materials have different effects on the color presentation of printed materials. Gloss, surface roughness, whiteness and light scattering are all paper properties that certainly will affect the color reproduction.Therefore, during the process of pattern production and comparison with the originals, it is necessary to use paper of the same material as […]

Tinplate Can Since the mid-20th century, offset printing inks have been packaged in tinplate cans. These cans are preferred for their high strength, making them easy to transport, and their excellent barrier properties, which help preserve the ink. With the rise of large-scale offset printing plants and increasing environmental requirements for ink waste disposal, the

In offset ink formulation, white ink and reducer are often used, but they serve distinct purposes due to their inherent properties, which operators should not confuse or interchange. Role in Ink Formulation White Ink: Adding a small amount of white ink to colored ink can alter its tone, softening it to create a refined and

Ink transferability refers to the ability of printing ink to be effectively transferred through the various components of a printing press and ultimately onto the substrate (such as paper or other materials). This property is crucial in determining the quality and consistency of the printed image. Transferability involves several stages, including the ink’s movement from

Ink tack and ink viscosity are two distinct properties that describe different aspects of ink behavior in the printing process. Here’s a breakdown of each: Ink Viscosity Ink Tack Key Differences Both properties are critical in determining the printability and performance of inks in various printing processes, and their optimal values can vary depending on

Ink fluidity refers to the ease with which ink flows under specific conditions. It is a critical property in printing processes as it affects the ink’s ability to transfer from the printing plate or cylinder to the substrate. Good fluidity ensures consistent ink coverage, smooth application, and high-quality print results. Fluidity is closely related to

UV/LED inks are specially formulated to cure quickly when exposed to ultraviolet (UV) or LED light. These inks are commonly used in various printing processes, including offset, flexographic, and digital printing, due to their fast curing times, durability, and environmental benefits. Here’s a detailed breakdown of their composition: Main Components Monomers: Oligomers: Photoinitiators: Pigments: Additives:

Conventional offset printing ink is composed of several key components, each serving a specific purpose to ensure the ink performs well during the printing process and produces high-quality prints. Here is a breakdown of the typical composition of conventional offset printing ink: Main Components Pigments: Binders (Resins): Solvents: Additives: Detailed Breakdown Pigments: Binders (Resins): Solvents: Additives:
