Product Introduction

Ink rollers are key components in the ink delivery system of a printing press, primarily responsible for delivering a precise and even amount of ink to the printing plate. They are broadly classified into three types: inking rollers, transferring rollers, and impression rollers.

① Inking rollers (also known as ink fountain rollers) are used to extract a set amount of ink from the ink fountain each time (also known as ink distributing rollers).

② Transfer rollers receive this ink and distribute it evenly (also known as impression rollers).

③ Impression rollers are responsible for evenly distributing the transferred ink onto the printing plate.

The even distribution of ink ensures that the ink is transferred uniformly and accurately to the printing plate, thus guaranteeing the quality of the printed product.

Yin Xing Product Advantages

1. Materials

1) We conduct strict quality checks on all raw materials upon arrival. The quality of raw materials is the cornerstone of the final quality of rubber products.

2) We also strictly control the selection of raw materials, and only materials that pass a series of tests, including small-scale, medium-scale, large-scale trials, and finished product trials, are used.

2. Process

1) Our equipment is the most advanced processing equipment.

The mixing equipment is advanced auxiliary equipment with an automatic weighing system, reducing human error. Vulcanization is performed in advanced intelligent temperature-controlled vulcanization tanks, ensuring stable time, temperature, and pressure during the vulcanization process. The machining equipment is also the latest Shanghai machine tool, with high processing precision and improved surface cleanliness of the rubber rollers.

2) The mixing process uses a two-stage mixing method, and the molding process uses continuous extrusion winding molding. The winding molding process has high production efficiency, can meet the needs of large-scale production, has high molding precision, and enhances product competitiveness.

3. Performance Advantages and Impact on Printing Quality

Performance Comparison

1. Physical Properties

1) Hardness: Our company's high-quality printing rollers offer a wider range of hardness options, customizable to meet specific customer needs. Standard hardness for printing rollers ranges from 28A to 40A, all of which can be produced;

2) Elasticity: The printing rollers produced by our company use high-quality materials and advanced manufacturing processes, resulting in excellent elasticity. A decrease in elasticity recovery ability affects the stability of the printing effect.

3) Smoothness: Our company controls different smoothness values for different parts of the printing press, resulting in a fine and uniform surface. Ordinary rollers have some shortcomings in the uniformity and fineness of smoothness, which will affect the surface quality of the printed matter.

2. Ink Transfer Performance

Ink Transfer

Uniformity of Ink Transfer: High-quality ink rollers can transfer ink evenly to the printing plate, resulting in consistent ink color on the printed matter;

Ink Transfer Amount Control: Precisely control the amount of ink transferred to ensure the printing plate receives the appropriate amount of ink;

Wear Resistance: High-quality ink rollers have good wear resistance and can maintain good ink transfer performance over extended use. Ink rollers with poor wear resistance may wear out quickly, affecting ink transfer quality and service life;

Cleanliness: Easy-to-clean ink rollers can reduce ink residue and drying on their surface, helping to maintain the stability and accuracy of ink transfer;

Maintenance Cost: Some ink rollers may require more frequent maintenance and servicing, increasing the cost of use. Ink rollers with good performance and durability can reduce maintenance costs.
