XBH-304 30cm DTF Printer - Intelligent White Ink Circulation Clog-Free System
Brand XBH
XBH-304 30cm DTF features intelligent white ink circulation that keeps pigment evenly suspended, preventing sedimentation and nozzle clogging. CMYK+W 5-color system delivers vibrant results on all garments. Custom-matched ink formulation ensures smooth, consistent printing with fewer interruptions and less maintenance downtime.
Q: What can I fit on a 30cm wide DTF film?
A: The 300mm (about 12 inch) film width covers most standard apparel transfer sizes. A typical adult t-shirt chest design (about 25-28cm wide) fits comfortably. Full-front designs for youth and adult sizes fit within the width. You can also gang multiple smaller designs — left chest logos, sleeve prints, label tags — side by side on one film to maximize material usage. For hoodies, the standard chest and pocket designs fit well. For accessories like hats, bags and shoes, the designs are typically smaller, so you can fit many across the width. The 30cm format strikes a good balance: wide enough for most common apparel transfers, but not so wide that you're wasting film on smaller designs.
Q: How does the white ink circulation system prevent clogging?A: White DTF ink contains heavy titanium dioxide pigment particles that naturally settle to the bottom of the ink supply if the ink sits still for any length of time. Settled pigment is the leading cause of nozzle clogs in DTF printers — the heavy particles can block the tiny nozzle openings, causing missing prints, weak ink flow and inconsistent white coverage. The intelligent circulation system keeps the white ink continuously moving and mixed, so the pigment particles stay evenly suspended in the liquid rather than settling. This means the ink that reaches the printhead is always consistent in density and composition, with no settled particles to cause blockages. By keeping the ink in motion, the circulation system dramatically reduces the risk of clogs and the maintenance headaches that come with them.
Q: What problems does white ink clogging cause in DTF production?A: When white ink nozzles clog, you get inconsistent white coverage on the transfer film — some areas look bright and opaque, while others look thin, gray or patchy. Since the white layer is the underbase that the color sits on, uneven white directly affects the final garment print quality — colors look muted or washed out in areas where the white is thin. Severe clogs can cause missing lines or entire sections of the design to not print at all, ruining the film and wasting material. Clogged nozzles also require time-consuming cleaning cycles to resolve, taking the machine out of production and reducing your daily output. The circulation system prevents these issues before they start, keeping the white ink flowing smoothly and consistently for reliable, repeatable results.
Q: What is the CMYK+W 5-color ink system?A: The machine uses a 5-color ink configuration: Cyan, Magenta, Yellow, Black (CMYK) for the color layer, plus White (W) for the underbase and highlight layer. In DTF printing, the white ink serves two important functions: first, it's printed as an underbase beneath the color layer to create an opaque foundation, which ensures that colors show up vibrantly when pressed onto dark or colored garments; second, white can be used as a highlight or design element on its own. The CMYK+W system is standard for DTF because it delivers full-color printing capability with the white support needed for dark garments. The custom-matched ink formulation is designed to work specifically with this machine's printheads and circulation system, ensuring smooth ink flow, consistent color and reliable performance.
Q: How much maintenance does the white ink system require?A: With the circulation system in place, daily white ink maintenance is minimal. The circulation runs automatically to keep the ink mixed, so you don't need to manually stir or shake the white ink bottles. The main routine tasks are running a nozzle check to verify all white nozzles are firing correctly, and running a cleaning cycle if the nozzle check shows any missing or weak nozzles. The auto cleaning function handles most routine printhead maintenance with a single button press. For longer idle periods — weekends, holidays — the circulation system continues to protect the white ink from settling, so you're less likely to come back to clogged nozzles after time off. The overall effect is less time spent on white ink maintenance, fewer production interruptions, and more consistent print quality day after day.
