1. Functions of Transparent Print Primer Spray

The coating material quickly absorbs and secures water-based inks, ensuring clear and vibrant printed images that resist smudging and accumulation.

2. Precautions for Using Transparent Print Primer Spray

2.1 Precautions Before Use

Cleaning the Material Surface：

Before applying the Transparent Print Primer Spray onto flat materials, wipe away any stains or foreign particles on the material surface using a lint-free cloth.

Placing the Material Flat：

Materials requiring Transparent Print Primer Spray should be placed on a flat, well-ventilated surface before spraying.

Applying Even Coats：

When using the Transparent Print Primer Spray, apply two even coats. To ensure a uniform spray distribution, it is recommended not to hold the can too close to the material surface.

Wearing a Protective Mask:

A protective mask should be worn when using the Transparent Print Primer Spray.

Using After Drying:

After drying and curing, the Transparent Print Primer Spray forms a clear protective film. Inkjet printing should be performed on top of this cured transparent layer.

2.2 Precautions After Use

Avoid Scratching with Hard Objects：

After inkjet printing on the cured Transparent Print Primer Spray layer, do not rub the surface with hard objects, as this may damage the transparent coating formed by the primer.

Avoid Cleaning with Water：

Do not clean the Transparent Print Primer Spray coating with water or other liquids, as moisture will damage the transparent film layer.

Avoid Rubbing with Skin：

Sweat and oils from the skin may affect the integrity of the Transparent Print Primer Spray transparent coating, so direct skin friction should be avoided.

3. Printing Results Without Using Transparent Print Primer Spray

3.1 Inkjet Printing Results on Basswood Board

The direct inkjet printing results on the basswood board show that the ink spreads on the wood surface, causing noticeable bleeding and resulting in blurred image edges.

3.2 Inkjet Printing Results on Other Materials

For glass, acrylic, and stainless steel materials, direct inkjet printing produces poor results. The ink is unable to form a complete pattern on these surfaces.

4. Inkjet Printing Results When Using Transparent Print Primer Spray

After applying the Transparent Print Primer Spray to the material surface, inkjet printing can be performed on the coated area. The printed images appear complete and sharp, and the text details are rendered with high clarity.

5. Usage Effects of Clear Paint Spray

After applying the Transparent Print Primer Spray, the material becomes suitable for inkjet processing. Once the inkjet printing is completed, a Clear Paint Spray may be applied to further protect and preserve the printed surface.

Clear Paint Spray provides substrate protection by forming a transparent coating layer that shields the material from air, moisture, oil, and ultraviolet light. This protective layer helps prevent corrosion or deterioration of various substrates—for example, rusting of metals, moisture-induced deformation of wood, aging and yellowing of plastics, and color fading of craft materials. Additionally, it enhances surface abrasion resistance and minimizes the appearance of scratches.

Clear Paint Spray can also improve the visual appearance of inkjet-printed images. Certain formulations contain gloss-enhancing components that fill minor surface irregularities, resulting in increased smoothness and improved surface luster.

Note: When selecting a Clear Paint Spray from the market, ensure that you choose a non-water-based formulation.

5.1 Usage Effect of Clear Gloss Paint Spray

Gloss Level：

After drying, the spray forms a high-gloss, mirror-like transparent coating. It reflects light strongly and significantly enhances the surface brightness of the substrate, making underlying colors—such as printed graphics or metallic textures—appear more vivid, saturated, and visually striking. The overall finish presents a clear, refined, and premium “high-gloss” effect.

Texture：

The surface becomes smooth and delicate to the touch, with a flat and refined finish. It exhibits a subtle “mirror-reflection” effect, making it suitable for highlighting the natural luster of the material or intensifying the color depth and visual impact of printed patterns.

Visual Characteristics：

While the coating may easily show fingerprints and minor scratches, it provides a “fresh” and polished appearance, making the substrate look newer and more refined. This finish is ideal for applications requiring a luxurious, eye-catching, and visually bold presentation.

5.2 Usage Effect of Clear Matte Paint Spray

Gloss Level：

After drying, the coating forms a non-glossy (or low-gloss) matte transparent film. When exposed to light, it produces diffuse reflection rather than sharp highlights, resulting in a soft and understated overall appearance. This finish helps reduce the visibility of minor surface imperfections such as scratches or slight color inconsistencies.

Texture：

The surface presents a subtly frosted, fine matte texture (with some formulations offering a smoother matte finish). It is restrained and calm in appearance, delivering a stable, vintage-inspired visual feel. This type of finish is ideal for highlighting the natural grain or texture of materials such as wood, leather, or matte plastics.

Visual Characteristics：

The matte surface is less prone to showing fingerprints or scratches and generally offers better resistance to dirt. It is well-suited for applications that aim for a minimalist, premium, grey-tone aesthetic or a retro style—such as furniture, cultural and creative products, or understated metal components.
