The Advancement of DTG Pretreatment

When you consider the term "advancement," you likely consider changes that happen throughout a long period of time. Not so with anything pertaining to direct-to-garment (DTG) printing.

Relative to pretreatment services and also methods, advancement and also progress have actually happened quickly as well as angry, with the objective being to prepared garments for this blossoming decor process as quickly as possible. For a design technique that is only around 10 years old, there have actually been many adjustments-- and also more are on the horizon.

Inkjet print heads determine the kind of water-based ink made use of, which subsequently determines the way printing is done on dark garments. In DTG printing, pretreating is called for when making use of white ink, whether as a white photo or an underbase. Using embroidered keychains on light garments when publishing only CMYK is a matter of individual choice. Will the picture be a lot more crisp as well as clean better with pretreatment on a light garment? Yes, yet a print without pretreatment also serves.

There has been much experimentation during the past years in the look for efficient methods to use a consistent as well as also layer of pretreatment option. Adhering to is a consider where we have actually been, as well as techniques as well as methods we have actually left because respect.

Hand-Held Pump Sprayer

This very early attempt at pretreating garments for DTG printing worked to the level that you can distribute the pretreat remedy, however the uneven application could be seen in the final print. An uneven application will look like brilliant as well as dull locations throughout the print. It's exceptionally rare to see a driver utilizing this technique today.

Display Printing The Pretreatment

Because a lot of the early innovators in this sector were longtime screen printers, it was only all-natural to attempt to evaluate print the pretreatment onto the shirt. The difficulty remained in just how slim pretreatment service is as well as attempting to use it via a display no matter exactly how fine the mesh. Adding thickeners to the product led to a hefty application on the garment, creating a tight feel. It was an affordable concept that just really did not pan out.

Power Paint Sprayer

The power paint sprayer developed as a practical method to control laydown of pretreatment remedy on the shirt and also, to now, is one of the most frequently utilized technique. The downside is the mess left due to overspray. It takes practice to obtain the stroke just right utilizing this method.

Likewise, by atomizing the pretreatment option as well as having it float in the air, this technique should be done in a separate place from your DTG maker. It is necessary to keep in mind that numerous operators tend to set way too much pretreatment option using this approach.

Paint Roller

A rather short-lived experiment to minimize the paint sprayer atomized solution as well as mess was using a paint roller. The result was too much remedy on the garment, lost product trapped in the roller as well as the lengthy aspect of using, then drying out the soaked-with-pretreatment garment. Enthusiasts and also some drivers still choose this technique, yet it was, essentially, an additional experiment that really did not fairly pan out.

Pretreat Papers

There has actually been trial and error as well as, in fact, application of pretreat papers-- paper with a covering of damp pretreatment service. While the principle is great and there is some prospective for the future, the price still is high and it is challenging to control the amount of solution applied. Various garment designs as well as brands will certainly need the capability to extra carefully manage the laydown quantity.

Carding/Rolling The Material

One more very early experiment was to draw a plastic card or paint roller across the fabric after applying pretreatment option. The purpose was twofold. Initially, laying the fibers of the tee shirt down results in a better completed product. Second, the card or roller would even out an irregular laydown of pretreatment.

New methods of pretreatment have eliminated the demand to level the service on the shirt. Understanding how to appropriately dry the t shirt-- using heavy stress on the heat press-- makes setting the fibers before treating unneeded.

Pretreatment Today

There are 2 recognized methods for expertly pretreating garments that will be printed via the DTG technique. A lot of designers getting in the market now choose automated pretreating. This is the most constant, repeatable and also cleanest method offered. An automated pretreater will certainly remove the variable of continually even pretreatment from the decoration equation.

Under limited budget plan restraints, the power paint sprayer still is a feasible alternative. Several long time DTG designers have actually developed skills in using pretreat with a hand-held power sprayer and also remain to utilize this technique. However these drivers usually make the financial investment right into automated pretreatment machines as a necessary aspect in their production packages.
