1.Introduction

As is well known, sublimation technology places stringent requirements on coating chemistry, ink absorption, and humidity stability. The coating design of sublimation paper determines its drying speed, transfer rate, color reproduction, anti-ghosting properties, and industrial production efficiency.

We are ISO9001, ISO14001, and FSC certified sublimation manufacturer, operating a large-scale coating plant equipped with 16 fully automated coating production lines, with a daily output of 12 to 15 million square meters. We also have a dedicated paper performance laboratory capable of conducting the following tests:

1. ΔE color difference analysis
2. High humidity curl simulation
3. Coating uniformity testing
4. Ink load durability testing (100%–300%)
5. Industrial printer compatibility testing (Epson and Atexco)

This white paper provides data-driven comparative analysis based on validated test results from our GL product (sheet and roll size) technical documentation.

2.Micro-Porous vs. Swellable Coating Technology

The coating structure of sublimation paper fundamentally determines the absorption, drying, and release mechanisms of sublimation ink.

Our GL series features a five-layer microporous engineered coating design:

1. Base paper
2. Anti-curling layer
3. Water separation layer
4. Microporous ink absorption layer
5. Surface transfer layer

2.1 Structural Advantage of Micro-Porous Technology

Performance Metric	Micro-Porous Coating	Swellable Coating	Technical Notes
Drying Speed	3–5 seconds	10–20 seconds	Porous structure absorbs ink instantly
Ink Load Capacity	High	Medium	Supports high-saturation and photo-quality prints
Fine Text Sharpness	4–6 pt	6 pt and above	Small text shows clear edges
Line Edge Accuracy	±0.05–0.1 mm	±0.2 mm	Better for patterns with fine outlines
Color Reproduction	95–98%	85–90%	Micro-porous layers release dye more evenly
Humidity Resistance	Excellent	Poor	Swellable coating absorbs moisture easily
High-Speed Printer Compatibility	≥ 300 mm/s	≤ 150 mm/s	Suitable for industrial production
Consistency Across Rolls	High	Medium	Micro-porous coating is more stable in large roll format
Cost	Slightly higher	Lower	Higher cost brings significantly higher performance

Why Micro-Porous is the Choice for Professional Production

Micro-porous technology:

Enables fast drying, reducing smudging and downtime
Supports high-density printing (deep blacks, neon colors, full saturation)
Performs better in humid environments, avoiding roll deformation
Ensures batch consistency, critical for wholesale buyers
Matches high-speed industrial printers

For these reasons,we uses 100% micro-porous coating across its sublimation paper roll series.

2.2 Technical Data from Our Laboratory

GL Series — Basic Physical Parameters

Parameter	GL120	GL100	GL70(Jumbo Roll)
Basis Weight (gsm)	120.69	100.81	56.63
Thickness (µm)	148	124	73
Drying Time (20°C, 52%RH)	23 sec	25 sec	53–88 sec
Whiteness (%)	88.3	89.3	89.4

Interpretation:

GL100（sheet and roll size） is optimized for both desktop and industrial printers.

GL70（now 29gsm-70gsm） is ultra-lightweight but still maintains high transfer stability.

GL120 provides best flatness and uniformity for textile production.
