0.15mm Aluminum PS Plate Supplier

A PS plate is a type of printing plate made from high-purity aluminum as the base material, with a uniformly coated photosensitive layer on the surface after electrochemical treatment. Through processes such as exposure and development, the photosensitive coating forms oleophilic image areas and hydrophilic non-image areas, enabling the transfer of ink required for printing.

The 0.15mm thick aluminum PS plate is a lightweight plate specification, typically made from 1050, 1060, or 1070 series aluminum alloys with a purity of ≥99.3%. Processed in the H18 (hard) temper, this thickness ensures mechanical strength while reducing costs, making it suitable for medium-to-short and some medium-to-long printing runs.

Production Process of PS Printing Plates

1. Aluminum Selection and Cleaning
High-purity aluminum sheets with a clean, defect-free surface are chosen, then undergo alkali and acid cleaning to remove oxides and oils.

2. Electrochemical Roughening
An AC/DC alternating electrochemical roughening technique is applied, forming a uniform and fine micro-porous structure to improve coating adhesion and development performance.

3. Anodizing Treatment
The aluminum substrate undergoes anodization, creating a dense oxide layer on the surface that enhances corrosion resistance and hydrophilicity.

4. Photosensitive Coating Application
A high-speed automated coating machine applies a uniform photosensitive layer (typically diazo resin or UV-sensitive material) with micron-level thickness control.

5. Drying and Inspection
The plates are dried at a constant temperature and tested for photosensitivity uniformity, surface tension, and wear resistance to ensure stable quality before leaving the factory.

Core Advantages of 0.15mm Aluminum PS Plates

• High Flatness and Stability
  At 0.15mm thickness, the plate maintains rigidity while being highly flexible, minimizing warping during mounting or printing and ensuring even printing pressure for precise registration.

• Excellent Photosensitivity
  High-sensitivity coating materials allow rapid exposure, short development time, and sharp image edges, supporting high-resolution printing (150–200 lines/inch).

• High Printing Endurance
  The anodized aluminum substrate provides excellent wear resistance, allowing 0.15mm PS plates to print 100,000–200,000 sheets, with some reinforced plates reaching over 300,000 sheets.

• Wide Development Tolerance
  The photosensitive layer adapts well to developer solution variations, maintaining stable imaging even under minor deviations, reducing scrap rates.

• Environmentally Friendly and Recyclable
  The aluminum substrate is 100% recyclable, supporting green printing and sustainable development.

• Easy Operation
  Compared with thicker plates, the 0.15mm thickness makes mounting and dismounting easier, reducing operator fatigue and increasing production efficiency.

Thickness Options

As a professional PS plate manufacturer, Hongchang Aluminum offers multiple thickness options for aluminum-based PS plates: 0.10mm, 0.15mm, 0.25mm, 0.27mm, 0.30mm, and others, customizable to client needs.

Thinner plates (e.g., 0.15mm): Better handling, lower cost, suitable for medium-to-short runs and fine printing.

Thicker plates (e.g., 0.3mm): Higher printing endurance and stability, ideal for long-run printing.

Applications

• Commercial Printing
  Used for magazines, brochures, posters, and catalogs, ensuring accurate detail reproduction and color consistency.

• Packaging Printing
  Performs well in boxes, labels, and gift packaging, maintaining image clarity even during extended print runs.

• Newspaper Printing
  The lightweight 0.15mm plate is stable on high-speed rotary presses, minimizing breakage, suitable for newspapers and advertising inserts.

• UV and Specialty Printing
  Some 0.15mm aluminum PS plates are compatible with UV inks, offering chemical resistance and supporting UV or metal printing applications.

Storage and Usage Recommendations

1. Storage Environment: Keep at 10-25°C, relative humidity 40-60%, avoiding direct sunlight and moisture.

2. Handling Precautions: Avoid direct contact with the photosensitive surface to prevent fingerprint contamination.

3. Exposure Control: Use light sources with the appropriate wavelength (typically 350-420nm) to ensure uniform exposure.

4. Development Time: Strictly control developer concentration and exposure time to avoid over- or under-development.

5. Pre-Printing Check: Ensure the plate surface is free of scratches, oxidation, or contamination before printing.
