Basic Understanding of 60-Line Gravure Rolls
The fineness of a 60-line gravure roll depends on how line count is defined. In the printing industry, line count usually refers to the number of lines per inch. 60 lines means 60 lines per inch, a density considered medium. Compared to higher line count gravure rolls, 60-line rolls have larger openings, resulting in greater ink transfer, making them suitable for printing applications requiring thicker ink layers.
Practical Application of Linearity
A 60-line gravure roller exhibits the following characteristics in practical use:
Ink Layer Thickness: Transfers more ink than gravure rollers with 80 lines or more.
Pattern Detail: Suitable for printing larger areas of color blocks and thicker lines.
Applicable Materials: Commonly used on substrates with relatively rough surfaces.
Factors Affecting the Perceived Linearity
These factors affect the actual perception of linearity on a 60-line gravure roller:
Ink Viscosity: Higher viscosity results in a thicker ink layer.
Printing Pressure: Increased pressure causes more ink to be transferred from the mesh to the substrate.
Squeegee Angle: Changes in angle affect the amount of ink released from the mesh.
