Applications for Carton Marking

Wood is a versatile material used across many industries. However, not every wood surface is equally suitable for printing or marking. The key factors influencing printability include the type of wood, surface texture, and moisture absorption.

1. Types of Wood and Their Characteristics

Softwoods (e.g., spruce, pine): Softwoods have an open-pore structure that absorbs ink particularly strongly. This can cause colors to bleed or appear less intense, thereby affecting print quality.
Hardwoods (e.g., beech, oak): Due to their denser cellular structure, hardwoods absorb ink more evenly, preventing excessive penetration. This allows for sharper contours and finer details in the print image, which is particularly advantageous for precise markings.
Uniform grain and smooth surfaces improve print quality: A regular grain without significant color variations or knots ensures even color distribution. Additionally, a smooth surface allows for better ink adhesion, making prints appear clearer and more uniform.

2. Optimization of Wood Surfaces

Sanding: Enhances ink adhesion and ensures uniform results. – Sanding removes irregularities and rough areas on the wood surface, creating a level surface. This not only improves ink adhesion but also prevents ink from pooling in depressions or rough areas, which could result in uneven prints.
Priming: Regulates ink absorption and improves print quality. – A primer creates controlled ink absorption, preventing the wood from absorbing too much or too little ink. This helps maintain color intensity and achieve a homogeneous print image.
Coatings: Lacquer or oil can enhance or reduce color impact. – Applying lacquer or oil can alter the appearance of colors. While glossy lacquers intensify and highlight colors, matte or oil-based coatings can mute tones and create a softer visual effect.

3. Moisture and Structure

High wood moisture leads to blurred prints and poor adhesion. Moist wood cannot absorb ink evenly, as the contained moisture hinders or delays ink penetration. This results in smudged or unclear prints, impairing the readability of markings.
Dry surfaces offer more precise printing results. Optimally dried wood ensures better ink absorption and allows for sharper print contours. The ink remains on the surface rather than soaking deeply into the material, ensuring a clear and distinct print image.
Grain and knots affect print uniformity. Irregular grain or the presence of knots can cause color deviations or gaps in the print image. Knots are particularly problematic as they absorb ink differently or even repel it entirely, making the print appear inconsistent.
