Pre-treatment Ratio & Quantity

You must use distilled water

Mix Ratio should be 1:1

When to change Pre-treat Mixture 1:1 to 1:2

When to change pre-treat mixture from

1. Certain garment colours may react negativity to a 1:1 ratio and may require the

mixture ratio of 2:1.

2. If applying a 1:1 mixture to a garment and after pressing it shows a strong

stain regardless of fluid speed you may need to change the mixture ratio. When

using a 2:1 mix ratio you may need to increase the amount of white ink for a

more vibrant print compared to a shirt pre-treated at 1:1.

3. You will want to mix a batch of pre-treat with 2 parts distilled water and 1 part

pre-treat ratio.

4. For example, you would mix 2 cups of distilled water to 1 cup of pre-treatment

to obtain a 2:1 ratio.

Pre-treat application to garment Dark & Light

Dark 30 Grams 1:1

Medium 24-27 Grams 1:1

Light 14-17 Grams 1:1

This mixing ratio might vary due to the type of garment which is used. Use your

experience!

your Pre-Treatment machine to weigh the amount of spray, with a scale, after

applying the Pre-Treatment liquid on a T-shirt!

Pouch Replacement - Very Important Process! R

Open the cartridge's lid on a fat surface and remove the empty pouch. Unpack

carefully a new ink pouch from its shipping carton

Push the green tip end of the ink pouch into the cartridge until it clicks into

place. Straighten the ink pouch to align it with the gutter of the lid of cartridge,

and mount in position inside the metal spring by pulling it with your hand. If

the edge of the ink pouch is bent or undulating significantly, make it straight

and fat with your hand to avoid wrinkles.

Place the pouch in a straight alignment with the cartridge. Align lines with each

other!

Close the lid, verify if the spring is rolling to the front. Place the cartridge at

around 45° and push on the 2 upper metallic latches to add a bit more tension

on the ink pouch. Double-check that you have not generated some wrinkles

again

Clean the outside of the green tip end that goes in contact with needle inside

printer. Attach a shelf life sticker included with ink pouch onto the front of the

cartridge.

Errors 2084 & 2085 (Winding-Up Failure) may occur if the white ink cartridges

are not loaded correctly.

WHITE INK

Best Practice for Printing!

Always keep the closest distance between the PRINT HEADS ant the surface of

the garment! It’s very important for the long life of your printer!

Adjusting the Height of the Platen

To provide an optimum printing image quality when a thicker textile is used,

you need to adjust the platen's height related to the thickness of the textile.

To adjust the platen height, loosen the Platen Fixing Lever and move the 1

Platen Height Adjustment Lever 2 to a lower position.

Re-tighten the Platen Fixing Lever if you are happy with new distance. Flatten

down all the wrinkles of the fabric. To check if new textile is not detected by

the sensor, push the button and repeat the process if needed! If you need to

go down further, remove 1 or 2 collars, loosen the knob 3 and push down the

platen bearing by 1 or 2 steps.

Reattach everything and tighten again the Platen Fixing Lever

Don't forget to bring back the platen to the A position after printing on thicker

material!

Always leave the knob 3 tighten after changing position!

If you have to print above the hem and seams, go for UNI-directional printing

to keep quality!
