Treated Xuan Paper for Gongbi

Treated Xuan Paper for Gongbi: What It Is and Who It Serves

Treated Xuan Paper for Gongbi (SKU GMO-XP-002) is bark fiber Xuan paper finished with controlled sizing (fanji), supplied in standard 69cm × 138cm sheets and graded specifically for gongbi and fine-brush painting. Sizing is the treatment that keeps ink from bleeding uncontrollably into the fiber; without it, the layered, precise strokes that define gongbi work are impossible to hold.

This product exists because treated papers fail in a specific, expensive way: uneven sizing means some areas of a sheet drink ink while others repel it, ruining a painting hours into the work. Every sheet we ship is tested for sizing uniformity, ink resistance, and surface smoothness, with sizing quality documentation and surface test records provided per batch. If you supply painting studios, run a fine-brush program, or distribute professional art materials, this page sets out what is confirmed about the paper and what to confirm with us before ordering.

The Sourcing Problems This Paper Is Built to Solve

Problem 1: uneven sizing across a sheet. The most damaging defect in treated paper is invisible until ink touches it — a patch of under-sized fiber absorbs where it should resist, and a detail stroke blooms. This paper is produced with controlled sizing application, and each sheet is tested for sizing uniformity before it leaves our facility.

Problem 2: quality drift between production batches. Studios reorder by the program cycle, not by the sheet, so a supplier whose sizing varies between batches forces painters to relearn absorbency characteristics with every delivery. Our sizing and surface treatment runs through a dedicated facility with uniformity verification equipment, and sizing quality documentation travels with each batch so your reorder matches your first order.

Problem 3: treated paper that sacrifices surface quality. Heavy-handed sizing can leave visible brush marks or a lifeless surface. Our process targets smoothness as a tested property, not just ink resistance — both are verified per sheet because gongbi painters need a surface that takes fine detail cleanly.

Specifications

Choosing a Sizing Level for Your Painting Style

Sizing level is the main buying decision for treated paper, and we produce three: light, medium, and heavy. Light sizing holds more of raw Xuan's absorbency — suited to painters who want controlled but still responsive bleeding for softer washes within gongbi work. Medium sizing is the general-purpose choice for standard gongbi practice and teaching, balancing ink resistance with a natural feel. Heavy sizing offers maximum ink resistance for the finest detail work, where every stroke must sit exactly where placed. If you are unsure which level your program needs, request samples of more than one level and let your instructors test them with your actual ink and pigment combination — sample response is confirmed within the ordering workflow below.

How Quality Is Verified per Batch

• Sizing uniformity test: each sheet undergoes a controlled ink resistance test verifying even sizing distribution across the surface — the failure mode that ruins gongbi work.
• Surface check: smoothness is inspected per sheet so fine-brush detail work meets a consistent surface standard.
• AQL inspection: shipments pass standardized AQL inspection before dispatch.
• Batch documentation: sizing quality documentation and surface test records are included with each batch, so studios and program administrators can verify the paper they receive against the standard they approved.

Custom Sheet Sizes and Program Supply

Beyond the 69cm × 138cm standard, we produce custom sheet sizes from 50cm × 100cm up to 97cm × 180cm — used by studios working in larger formats and by institutions matching paper to specific mounting or exhibition requirements. Combined with selectable sizing levels, this lets a program standardize on one paper source across multiple class levels and techniques. MOQ starts at 200 sheets, which supports a pilot semester or a single studio program before scaling to full supply.

Company Backing

Gu Mo Craft Technology (古墨工艺品) has produced treated Xuan paper since 2011 and operates a dedicated sizing and surface treatment facility — this is a specialized production line, not a finishing step added to raw paper output. Our testing station includes sizing uniformity verification equipment. We serve painting studios, art supply distributors, and cultural institutions across more than 30 countries with export documentation, and the documentation in each shipment traces back to the batches tested in our own facility.

Delivery Reference: A Studio Program Order

A painting studio in Korea ordered 3,000 sheets of treated Xuan paper for its gongbi painting program. Sizing-tested samples were delivered within 12 days, production was completed in 35 days, and the shipment went out with sizing quality documentation. The studio reported even ink resistance across all sheets and reordered for the next program cycle.

Where Buyers Have Seen This Paper

The Treated Xuan Paper was showcased at the China International Cultural Industries Fair and the Seoul Art Materials Expo. Our booth featured sizing comparison demonstrations and surface quality samples — letting gongbi painters and art supply distributors compare sizing levels side by side before committing.

Before You Order: Points to Confirm

MOQ is 200 sheets and lead time is 30–45 days after sample approval, with FOB, CIF, or DDP terms quoted per inquiry. When you contact us, having these details ready speeds up the quotation: sheet size and any custom dimensions, sizing level (or a sample set across levels), total quantity, your destination port and preferred trade term, and your program timeline. We will respond with current pricing and a sample arrangement so your instructors can verify sizing behavior with their own ink before the bulk order.
