When utilizing printers like the Epson G2100 for direct-to-film (DTF) printing, a common issue that users may encounter is the misalignment of white ink, which manifests as unwanted white ink appearing on top of images. This technical guide explores the root causes of this issue, offers solutions, and provides preventative measures to ensure high-quality printing results.

Root Causes of White Ink Misalignment

The misalignment of white ink in printing can often be traced back to the settings of the choke width in your printing software. Choke width controls the spread of white ink under the CMYK layers. An improper choke setting can lead to white ink creeping around the edges of colored inks, distorting the final image.

Adjusting the Choke Width

To resolve misalignment issues, adjusting the choke width setting is a critical step. Typically, in DTF or direct-to-garment (DTG) printing, setting the choke width to zero is recommended. This adjustment ensures that the white ink does not extend beyond the limits of the color inks, thus maintaining the sharpness and clarity of the design.

Here’s how to adjust the choke width:

1. Access the printing settings in your software, such as CadLink or Garment Creator.
2. Locate the choke settings, usually found under the ink configuration or print settings menu.
3. Set the choke width to zero. This setting will restrict the spread of white ink and keep it strictly beneath the color layers.

Verifying Software and Printer Calibration

Misalignment can also result from calibration issues between the printer and the software. Ensuring that both are properly calibrated is crucial for optimal results. Follow these steps:

• Run a calibration test on your Epson G2100 printer to ensure accurate ink placement.
• Check for any software updates for both CadLink and Garment Creator that might include bug fixes or enhanced printing accuracy.

Preventative Practices

To avoid future issues with ink misalignment, consider implementing these practices:

• Regularly maintain and clean your printer to prevent ink clogging and misfiring.
• Conduct regular tests to check the alignment and quality of prints, adjusting settings as necessary.
• Keep your printing software updated to leverage the latest improvements and fixes.
