DTF printers are often used for personalized, custom products. Due to the customized nature of these products, high printing precision is crucial. The printing precision of DTF printers is a key production requirement. I has compiled 8 factors that affect the printing precision of white ink transfer printers for your reference.
- Minimum Ink Droplet Size of the Print Head: Generally, the smaller the minimum ink droplet size, the higher the printing precision. Sometimes, the amount of ink and grayscale requirements need to be considered, selecting the appropriate combination of different ink droplet sizes for printing.
- Number of Print Heads: Under the same conditions, an increase in the number of print heads can affect printing precision. The combination of print heads for four-color, six-color, or eight-color output requires higher alignment accuracy, generally impacting printing precision.
- Arrangement of Print Heads: Under the same conditions, staggered arrangements increase printing width but require more passes, which can sacrifice printing precision.
- Compatibility Between Ink and Print Heads: The ability of the ink to form round droplets on the transfer film affects the final print quality. High compatibility between ink and print heads results in better printing outcomes.
- Number of Passes: With the same color input, fewer passes result in higher precision. This is one reason why staggered arrangements do not achieve the same precision as parallel arrangements.
- Transmission Precision and Platform Flatness of the Printing Equipment: Transmission precision and platform flatness affect the placement of ink droplets, influencing printing precision.
- Compatibility Between Control Boards and Print Head Waveforms: Different manufacturers’ control board algorithms vary slightly. The stability of the chip signal output and the waveform requirements for printing affect printing precision.
- Type of Transfer Film: Transfer films with good ink absorption properties, where the ink does not blur or spread, will result in higher printing precision.
Understanding and optimizing these factors can help achieve the best printing precision with white ink transfer printers.
