The Best Shirt or Tee Shirt for a DTG Printer
With so many shirt options, which brand should I use?DTG LED UV Tee-Shirt Printers
Your DCS UV-LED DTG Printer is ready to go. You are eager to begin production. You are ready to purchase in-bulk the shirts, tee-shirts, and/or garments you need to start. A simple Google search for 100% Polyester T-shirts produces approximately 3,750,000 results!! Where do you begin?Apart from recommending a specific shirt or tee-shirt manufactured by a specific company or corporation, it is moderately difficult to explain the process of selecting the “best” shirt or tee-shirt to print on directly. If you purchase even a few dozen tee-shirts from the various different shirt or tee-shirt manufacturers it still will not be until the tee-shirts arrive from the vendor to your own facility that you come to the realization that each shirt, t-shirt, or garment is drastically different in look and feel compared to one other. With that being said, Direct Color Systems has some guidelines and helpful tips for selecting the most appropriate tee-shirts to print on with your DCS UV-LED Printer.
Tips for selecting shirts and shirt fabrics to print on:
Shirts that do not require a white underbase:DTG UV
While this may not always be possible, shirts or tee-shirts that do not require a white underbase (i.e. white, light grey, tan, etc.), will always yield the best results. Not having to print a white underbase improves the feel and softness of the print on the shirt or t-shirt, decreases throughput time, decreases setup time, doesn’t require purchasing a spraying unit (for water) and washes significantly better. All of this, coupled with the fact that there is a much wider variety of shirts and t-shirts that yield acceptable output, makes printing to white or light shirts a no-brainer.
However, black or dark shirts are typically favored over white or light colored shirts. The selection process for shirts that require a white underbase is a little more involved and will require experimentation and validation by the operator.
Shirts containing a high percentage (80 or above) of synthetic fibers:
DTG with UV shines in its ability to print to synthetics shirts and performance polyester t-shirts. Therefore, the higher percentage of synthetic fibers used when manufacturing the shirt, the better the results overall. However, if the shirt does not require a white underbase, 100% cotton, various cotton/poly blends and 100% polyester all work extremely well. The higher ratio of synthetic to natural fibers is very important if the shirt or t-shirt requires a white underbase.
Dark and black cotton shirts, t-shirts, or garments:
Black or dark colored 100% cotton shirts are the most difficult type of shirt to achieve any acceptable results with. Understand that some of these shirts and tees will never yield acceptable results. There are process steps and software settings that can be changed in an attempt to yield better results, but overall printing to any black or dark shirt that is not in the list of recommended shirts may be printing, profiling, and process of futility. Also, note that the IRF6-T white ink with IRF6 CMYK & Clear will produce the best results when printing to black or dark cotton shirts, t-shirts or garmets.

Metal core lasers are constructed from aluminum and go through a passivation (micro-coating) process during manufacturing, building a thin, dense layer of ceramic (AL2O3) on all internal components and eliminating the possibility of metal contact with the gas mixture. This very thin ceramic layer (just a few microns) does not impact thermal conductivity. Both ceramic core and metal core lasers are decontaminated and evacuated to high vacuum levels in the manufacturing process to remove any contaminates before gas fill. Therefore, ceramic and metal lasers both offer contamination free cores.
One of the key advantages of metal core lasers is ease of cooling. Only part of the electrical energy consumed by a laser is converted to laser power, while the rest of the electrical energy is converted to heat. A CO2 laser’s gas mixture is sensitive to high temperature, and removing excess heat is extremely critical. Metal is a much better choice (as opposed to ceramic) for required laser cooling because the metal core transfers heat quickly in order to keep the laser mixture at optimal operating temperature. Ceramic is a relatively poor conductor of heat, making it a less than an optimal choice, especially for air-cooled lasers.
Another distinct advantage of metal lasers is linear polarization. Laser beams with linear polarization can be combined into a single, cross-polarized beam to produce a broader range of power options and to deliver superior advantages in laser material processing. Additionally, in systems compatible with multiple lasers, metal lasers with different power and wavelengths can be combined, sharing the same optical path. Conversely, current ceramic lasers produce randomly polarized beams that cannot be combined.
Finally, metal lasers can be serviced easily, thereby extending their useful life indefinitely. Hundreds of thousands of metal core lasers have been manufactured by ULS and other companies in the last 20 years, with many laser sources over 10-years-old remaining in service. While ceramic lasers could provide a reasonably long operational life, they are not designed to be maintained easily due to the direct attachment of the laser resonator optics to the ceramic core, using glue as a bonding and sealing material. Metal core lasers, on the other hand, use metal or semiconductor grade elastomeric seals. Metal lasers also can operate for an extended time in the field before maintenance is needed and are designed for long term reliability and serviceability.
As summary, top global laser system manufacturers design, manufacture, and use metal core air-cooled CO2 lasers in their laser systems because these lasers offer the broadest range of power options and unlimited laser lifetime for a vast list of laser material processing applications. When making a decision regarding a laser system, consider the advantages offered by metal core lasers.

When importing an image, sometimes you may need to edit the image or apply different tool paths. However, if the image or object is not grouped, then the only way to get it into pieces is to Break Path which breaks it all down. From there, you can edit, delete, etc., and when finished you can Make Path to make it into 1 piece again.
After bringing this border in from clipart, I then Break Path to edit it.
From here, I delete some of the inner rectangles, then Make path to make it back into 1 piece. It is not enough to just group it if you want to do a fill between the rectangles, that’s another reason to use Make Path.
