. **Material**
- **Construction Material**: Typically made from high-grade steel or stainless steel to ensure durability and resistance to corrosion.
- **Components**: Often includes rollers, print cylinders, drying units, and cutting tools, all made from robust materials to handle continuous production.

### 2. **Type**
- **Rotary Printing Machine**: Uses rotating cylinders to print designs on the wallpaper.
- **Flexographic Printing Machine**: Uses flexible plates and is suitable for high-speed production.
- **Gravure Printing Machine**: Known for high-quality print with detailed patterns.
- **Wallpaper Coating Machine**: Adds coatings like gloss, matte, or textures.
- **Cutting and Rewinding Machine**: Cuts the wallpaper to the desired length and rewinds it onto rolls.

### 3. **Size**
- **Machine Dimensions**: Varies depending on the model and capacity, typically ranging from compact sizes (e. G., 3 meters in length) to larger industrial units (e. G., 10 meters or more).
- **Roll Width Capacity**: Machines can handle different roll widths, commonly from 600mm to 1200mm, but industrial machines can go wider.

### 4. **Weight**
- **Machine Weight**: Depending on the size and type, the weight can range from a few hundred kilograms for smaller units to several tons for larger, more complex machines.

### 5. **Packaging**
- **Standard Packaging**: Usually, machines are packed in wooden crates or pallets, with protective materials to prevent damage during transport.
- **Shipping**: Machines may require disassembly and containerization for international shipping, especially larger units.

### 6. **Other Features**
- **Power Requirements**: Typically industrial power, e. G., 220V or 380V, depending on the region.
- **Automation**: Machines can range from semi-automatic to fully automatic, with digital controls for precise adjustments.
- **Printing Speed**: Measured in meters per minute, with high-speed machines capable of printing up to 100 meters per minute or more.
- **Maintenance Requirements**: Regular maintenance needed for rollers, print heads, and cutting tools.
- **Customization**: Machines can often be customized based on the specific needs, such as the type of inks used, design complexity, and additional features like embossing or laminating.

These specifications should be tailored based on your production needs, budget, and the scale of operations you plan to achieve.
