Tips for using Dark Cotton pretreatment optimised for GTX series printers

Follow these tips for using our Dark Cotton pretreatment for the Brother GTX series.

Our concentrated pretreatment is diluted with demineralised or reverse osmosis water to obtain a ready-to-use product. The recommended ratio is 1 volume of pretreatment to 3 volumes of water.

This dilution ensures that the liquid acts effectively on the textile.

Before launching into full production, perform tests to define the appropriate dosage of pretreatment for your fabric and ink specifications.

This will allow you to adjust the amount of product needed to achieve the best custom printing results.

After using Brother Ink Pretreat, be sure to dry the garment completely before printing. Adequate drying is essential to fix the pretreatment in the textile fibres.

For a clean and precise print, it is essential to smooth the t-shirt or textile before printing. This step eliminates wrinkles and allows for even application of ink over the entire printed area.

Testing Pretreatment Liquid for Brother GTX Pro Bulk or GTX 600.

Conducting pretreatment tests allows you to optimise the use of the product to achieve the best possible results on various types of textiles. These tests also help in determining a precise dosage, significantly reducing the volume of DTG pretreatment for Brother printers. This can lead to real savings by lowering your production costs.

Preparation for Tests

Before starting, ensure that the t-shirts or hoodies to be tested are clean and free of any substances that could affect the absorption of the pretreatment for GTX series. This includes stains, dust, and other residues.

Application of Pretreatment for Brother DTG

Apply the recommended amount of pretreatment to a small section of the t-shirt. Use different volumes to test the saturation and absorption effect of the ink on the textile.

Drying GTX optimised DTG pretreat

After applying the Brother DTG pretreatment op, the textile must be completely dried. Preferably use a Chiossi e Cavazzuti drying tunnel. For manual drying, use a heat press set to an appropriate temperature, usually around 170-180 degrees Celsius, for 30 seconds, and repeat if necessary.

Test Printing GTX optimised pretreat.

Observe the details, quality, colour vibrancy, and how the ink adheres to the t-shirt.


Examine the print results to determine the optimal level of pretreatment needed. Look for uniform and vibrant colours without any ink bleeding. Adjust the pretreatment quantities and repeat the test if required.

Record and keep the results of your tests, including the amounts of pretreatment used, drying parameters, and observations of your prints. This will help standardise the process for future productions and ensure consistent quality.
