China Photo Paper Suppliers - High-Quality 108gsm to 260gsm Factory Direct Double-Sided & Water-Resistant Printing
Product Introduction
Photo paper is a specialized paper type designed exclusively for image output. It is mainly divided into two categories: silver halide photographic paper and inkjet photo paper. The former relies on chemical photosensitive imaging, while the latter is compatible with digital inkjet printing. The two have distinct differences in characteristics, specifications, and application scenarios, as detailed below.
Core Characteristics
1. Inkjet Photo Paper (Mainstream for Civil / Commercial Use)
(1) Coating and Process Features
Classified by coating technology, there are three main types:
RC-Coated Photo Paper (Resin-Coated)
The most popular type. The paper base is coated with water-resistant PE layers on both sides, featuring a mirror-smooth surface. It absorbs ink quickly without smudging, dries rapidly after printing, and has excellent water resistance and fingerprint resistance. Its color saturation reaches 98%–100%.
Casted Photo Paper
Creates mirror gloss through high-temperature calendering technology, offering high color reproducibility and outstanding cost performance, ideal for dye ink printing.
Microporous / Swelling Photo Paper
Uses nanoscale microporous structures to lock ink, providing stronger light resistance and durability, suitable for long-term collection.
(2) Physical Properties
- Grammage: Determines paper thickness and stiffness — higher grammage means thicker, stiffer paper and less curling.
- Whiteness: Generally above 90, with low light transmittance to fully restore image details.
- Special Features: Anti-static, anti-curling, and fold-resistant properties, making it suitable for batch printing and long-term storage.
- Compatibility: Works with mainstream inkjet printers (Epson, Canon, HP) and both dye and pigment inks. With a maximum printing resolution of 5760 dpi, fine text and image details are clearly distinguishable.

1.2 Silver Halide Photographic Paper (Professional Photography Grade)
Based on a fiber paper base, it is coated with photosensitive emulsion and undergoes chemical development to form images. It boasts exceptional color reducibility and light resistance, with images preservable for decades or longer. The surface offers diverse textures:
- Glossy — high reflectivity, sharp clarity
- Matte — non-reflective, fingerprint-resistant
- Satin — silky luster, strong three-dimensionality
It is the core material for professional photo studios and art exhibitions.

Frequently Asked Questions
Q What is the main difference between inkjet photo paper and silver halide photographic paper?
Inkjet photo paper is designed for digital inkjet printers and uses coating technology to absorb ink and reproduce images. Silver halide photographic paper relies on chemical photosensitive emulsion and requires a darkroom development process. Silver halide paper is typically used in professional photography and art contexts due to its superior longevity and color fidelity.
Q Which type of inkjet photo paper is best for long-term preservation?
Microporous or swelling photo paper is the best choice for long-term preservation. Its nanoscale microporous structure locks in ink more securely, offering superior light resistance and durability compared to RC-coated or casted photo paper.
Q Is RC-coated photo paper compatible with all inkjet printers?
Yes, RC-coated (resin-coated) photo paper is compatible with most mainstream inkjet printers, including Epson, Canon, and HP models. It supports both dye and pigment inks and can achieve printing resolutions up to 5760 dpi.
Q What surface finishes are available for silver halide photographic paper?
Silver halide photographic paper is available in three main surface finishes: Glossy (high reflectivity and sharp clarity), Matte (non-reflective and fingerprint-resistant), and Satin (silky luster with strong three-dimensionality). Each finish suits different display and usage purposes.
Q How does paper grammage affect print quality?
Grammage determines the thickness and stiffness of photo paper. Higher grammage results in thicker, stiffer paper that is less prone to curling, which helps maintain a flat surface during and after printing, ultimately contributing to a more professional finished result.
Q Which photo paper type is recommended for professional photo studios and art exhibitions?
Silver halide photographic paper is the preferred choice for professional photo studios and art exhibitions. It delivers exceptional color accuracy, light resistance, and image longevity — with prints that can be preserved for decades or longer under proper conditions.
