Question:
Is it necessary to use C2 size tubing for color inks and C3 size tubing for white inks in my printer setup? Or can I use C3 tubes for all inks?
Answer:
Tubing Size Recommendations for DTF Ink Lines
In the world of DTF conversions and custom ink delivery systems, selecting the correct tubing size is crucial for maintaining consistent ink flow and preventing clogs, particularly with white ink, which is prone to settling and separation.
C2 vs. C3 Tubing:
-
C2 tubing typically has a smaller inner diameter than C3.
-
C3 tubing is wider, allowing for better flow, which is particularly important for heavier pigment inks, such as white.
Recommended Configuration:
-
Color Inks (CMYK): Using C2 tubing is commonly sufficient because these inks have a lower viscosity and do not settle as aggressively as white ink.
-
White Ink: It’s usually best to use C3 tubing due to the thicker consistency of white ink. The larger diameter helps prevent clogging and supports better ink circulation, especially if your printer uses an agitation system or a circulation pump.
However, as you noted in your original approach:
"That will be my choice. However, it won't hurt if you use all C3 tubes for everything. I don't usually put white ink in C2."
This is absolutely valid. If you want to simplify your inventory or reduce the risk of mismatched tubes during replacement, using C3 tubing for all ink lines (including CMYK) is entirely acceptable. There are no known downsides in most systems to using a larger tube for color inks. The ink will still flow properly, and maintenance may be easier due to reduced risk of clogs.
Summary:
-
Preferred: C2 for color, C3 for white.
-
Universal (Safe Choice): C3 for both white and color inks.
This setup is not only technically sound but also makes maintenance and parts replacement simpler, especially for DIY users who want fewer variables to manage.
Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. Therefore, we're unable to provide remote troubleshooting, suggestions, or support for printer repairs. We offer an in-person evaluation and repair service via our local diagnostic facility (https://bchtechnologies.com/printer-repair-service). Given the high demand, we operate on a first-come, first-served basis. Therefore, it may take a few weeks before we can arrange for your printer to drop it off. Our services are structured to repair either the whole printer or specific parts, with clear instructions on how to proceed. However, we acknowledge that our rates aren't the most economical. Thus, we recommend that you resort to self-help via online research. You can start by checking out YouTube or visiting our YouTube channel's homepage (https://youtube.com/@bchtechnologies). Look for specific videos using the search icon next to "About" on the right-hand side of the menu bar. I receive dozens of queries every day asking about videos for specific topics. Having created videos over the past nine years, it's challenging to remember every single one. Therefore, using YouTube's search function would be the most efficient approach. Additionally, YouTube may suggest relevant videos from other channels that can assist you.
