The wire rod we used in the experiment is RK K HAND COATER from the UK. Wire rods provide an easy coating method for accurate, repeatable surface coating of most substrates. Wire rods are precision stainless steel wires wound on stainless steel rods to form rods with grooves of different shapes. These grooves allow precise control of applied wet film thickness. Tightly wound rod coating thickness range: 4-120 μm, higher coating weight 150-500 μm can be obtained by spiral wire rod.
1. First, prepare a substrate of appropriate size for proofing. For small imprint beds, the size is 12×21 cm; for large imprint beds, the size is 18×31 cm.
2. Place the substrate on the impression bed and hold it with clamps.
3. Select the appropriate type of wire rod. Place on the imprint bed, next to the clamps.
4. The ink for proofing is placed close to the clamp, about 1 cm below the filament rod.
5. Hold both ends of the wire rod with both hands, and pull the wire rod toward the operator at a constant speed and pressure, and do not turn the wire rod during this process.
6. After proofing, wash the wire rod in a suitable solvent and dry it with a cloth. Silk rods need to be kept dry .
