What Is Hydrographics
Hydrographics, also known as Water transfer printing hydro dipping, water transfer printing, hydrographic printing, immersion printing, hydrographic dipping or cubic printing, is a method of applying printed designs to three-dimensional surfaces with liquid and some chemicals. The hydrographic process can be used on metal, plastic(PVC, PP, PE, PET, ABS, ACRYLIC, AND SO ON), ceramics, fiberglass, glass, rubber, hardwoods,
The water transfer printing process is extensively used to decorate items that range from entire all-terrain vehicles and car dashboards to small items like bike helmets or other automotive trim. Films can be applied to all types of substrates including plastic, fiberglass, wood, ceramics, and metal. For the most part, if the item can be dipped in water and can be painted using traditional techniques then the hydro dipping process can be used.
In the process, the substrate piece to be printed first goes through the entire painting process: surface preparation, priming, Dipping, Washing(Rinsing), drying, and top coating(clear or matte). After painting but before top coating, the part is ready to be processed. A (polyvinyl alcohol) PVA hydrographic film, which has been gravure-printed with the graphics image to be transferred, is carefully placed on the water’s surface in the hydro dipping tank. The clear film is water-soluble and dissolves after spraying hydro dip activator. Once hydro dipping is begun, the surface tension of the water will allow the pattern to curve around any shape. Any remaining residue is then rinsed off thoroughly by rinsing station. The ink has already adhered and will not wash off. It is then allowed to dry.
The quality of hydrographic dipping depends on many factors, such as high-quality clear PVA film, ink, the printing plate, hydrographic activator, and good quality hydrographic tank with heater and water recycling.
TSAUTOP Hydrographics film is made by the high-quality PVA film imported from Japan, the thickness 35-40μ，high quality durable and consistent ink with UV resistance, printed by 8 colors gravure printing machinery, High definition pattern. TSAUTOP have the most popular hydro dipping patterns in stock, such as the skull, flame, carbon fiber, camouflage, cartoon, wood grain, stone, metal, abstract, flower. All types of water transfer printing film has more than 20,000 patterns. In these patterns, carbon fiber hydro dip, camo dipping, hydro dipping skull patterns, flame dip film, wood grain hydro dip are welcomed by hydro dipping man. Furthermore, TSAUTOP develops 30 new hydro dip designs per month and can customize your hydro dipping patterns in 7-10days.

As we know, the water transfer printing film have many types, so the activator is not changeless. TSAUTOP can supply hydrographic activator sample for diy hydro dipping and water transfer printing activator formula for starting hydro dipping. We can guide all customers to compound hydrographic activator. The adhesion is a result of the chemical components of the activator softening the base coat layer and allowing the ink to form a bond with it. One of the most common causes of a failure to achieve adhesion between the two layers is a poorly applied activator. This can be either too much activator being applied or too little. Quality activator is one of the most important elements in producing a high quality, professional hydrographic printing.
Moreover, TSAUTOP can provide various HLVP spray gun as your requirements, such as hydro dipping activator spray, base coating spay, top coating spray.
How To Hydro Dip Correctly
Pretreatment on Products Before Hydro Dip
Surface cleaning without grease or other impurity is vitally important to a successful hydro dipping process.
Experiences show many hydrographics failures come from poor pretreatment on the products.
Detailed requirements on pretreatment as follows:
1.First inspect the products if there is obvious impurity on the surface of the products. Polish the surface with
800-1000mesh sandpaper. Carefully don’t polish too hard to leave scrapes on the surface.
2.Touch the products if the surface is smooth. If the surface is rough with sandy feeling, polish it again.
3. Observe the products if there is oil stains, dust or other impurities on the surfaces. Remove the oil stains or
dust by proper methods. For example, remove the dust with a clean rag or the stains with a suitable solvent.
4. To remove the inferior pattern from the hydro dipping process, you have to use the special pattern remover.
Or if the area of defects is small, you can use 800-1000mesh sand paper to remove the defects and trim with
a paint brush.
5. The products must keep clean after pretreatment.
6. The products must keep dry after pretreatment. Use an air dryer Or blower to remove the moisture on the surface of
the products. Or just leave the products in a clean and dry place (air-dry).
7.Place the pretreated products in a clean and dry location for the next process step.
The Operation Points of Hydro Dip
1. Before dipping, the products must keep clean and free from static electricity.
2. Ensure the water surface clean. No residue and activator on the water surface. Cleaning the water surface
through turning on the water pump for flushing the residue, then remove the bubbles of the water with the dividers slightly and slowly.
3. You have to distinguish the right side of the hydrographics film before dipping. Some hydrographics film the face side is matte,
some face side is glossy, if you put the reverse side of the hydrographics film on the water, the hydrographics film will not work, you can not
dip anything. So you can dip some water with one finger and touch a little corner of the hydrographics film, you can feel one side sticky, so
the side is the right side and towards the water. Do not let water drop to the other side when filming. So you put the film on the water with
a dry hand and keep a 30-40degree angle with the water surface. Pull the ends of the hydro dipping film from one end of the hydro dipping
tank to the other to avoid air bubbles. If there have some bubbles or film curling, you can remove the bubbles slightly by hand or blow it away
by the spray gun. Pay attention to damage the hydro dipping pattern.
When to start to spay the activator?
Timing for spaying of activator is also a trick for successful water transfer printing. After the film laying on the water, spraying activator has
no fixed time, because many water transfer printing film have different activated time depending on the blank hydrographic film, the ink and
the water temperature. The common time of spraying activator is in 45-90seconds. So, you have to observe the change of film. When the film is
spreading flat with light glimmer. Let’s start to spray activator now.
Another way to determine the time of the spray activator, you can spray little activator to the corner of the hydro dipping film, the sprayed corner
will turn to a layer like thin oil on the water without winkles. Let’s start to spray activator now.
How much activator spraying to the film?
This is something of skill or experience. We just run the spray gun crosswise from left to right or from the top to the bottom lengthwise.
Spraying activator only one time, don’t repeat on the activated surface, because this will disturb the pattern. The distance of the gun to the water
surface is 30-40cm. The liquid flow of spray gun need to be adjusted to maximum, the speed of running spray gun must be slow. The usual
amount of activator is 1 liter of activator to activate 30-40sqm hydrographic film by hand.
How does hydro dipping work
1. Cutting the suitable size dip film, ensure the film can cover the whole article surface. Not too big or too small for saving your film.
2.Pay attention to the dip angle (30-45degrees), ensure that the contact area of the object with water is minimal.
3.Attention the wave direction especially the pattern of wood grain. Or you may decide to turn the film 90°or 180° on the water. The dipping is
a continuous one-step procedure, no stop during the dipping process to ensure do the best dipping.
4.when the product dipped into the water, shaking it gently in the water and remove the floating film remains and take it in a tilted angle.
Do not allow the product to fall down.
5. When you finish dipping, check if there is any defect on the pattern(bubbles or cracks). This may give you an idea for
improvement on next dipping. If the remains stick to the product, rinse it away with water.
How long to change the water in the hydro dipping tank
The water in the tank must be maintained at a certain level.
In hydro dipping process, the water in not only used as media to give pressure for hydrographic dipping it also can wash away the remains.
The water need to change if you find the water is sticky or there are bubbles or lots of
remains floating on the surface.
How to wash after hydro printing
1. Take care not to touch the product by finger just out of the water. The ink layer at this time is very fragile, any touch may damage the just coated pattern.
2. The purpose of washing is to remove the sticky layer on the surface. Do not apply too heavy a pressure for washing.
The heavy water pressure may damage the just coated pattern.
3.After washing, touch the product by our finger. If you feel sticky on the product, please wash again. The sticky layer
must be thoroughly washed away, or the adhesion for the finish coating will be a problem.
4. You may also need to wash the other side (uncoated side) of the product because usually this side also need to dip
for another pattern or apply the finish coat.
How to deal with the defect product by trimming
1. Before the finish coating, the defected pattern need to be trimmed. The trimmer should prepare the same hydrographic film, activator, suitable tools such as paint brush and sand paper for such purpose.
2. Use the paint brush soaked with the activator to erase the defected area.
3.Trimming is only carried out on defects of the small area. If defects on the large area are found.
This should remove all pattern or cover the whole surface by painting.
4. The trimmer should each product before delivering to products to the spray booth.
5. Remove dusts or impurity on the trimmed products. Place the trimmed products in a dry and clean place. Which are ready to move to the spray booth for top-coating.
How to reworked defective products
1.Instructions on dealing with inferior products before finish coating
1.1 If a pattem s lacally damaged you can try to mend it by cutting off a piece of fim and dipping again
1.2If a total pattern is damaged, you have to remove the total pattern with sand paper or solvent and dip again.
2.Instructions an dealing with inferior products aftar finish coating
2.1 If lccal defects such as dust points or drippings appear on surface finish, polish the local surface with wax
2.2If the whole finis surface is a failure(dripping and primer penetration in the larger area). the finish has to be removed with solvent for renewal.
How to dry the dipped prodcuts after dipping and top coating
1. The temperature setting is essential for the baking process. The baking temperature depends largely on the material of the
product, The product may be deformed or degraded under clevated temperatures.
2. The temperature setting for drying dipped products after washing.
thermoplastic and nonmetal products: less than60℃;
metal products: Max180℃, because the primer can not stand higher temperature;
If the products is coated with two component PU paint as a primer, you should observe exactly the paint manufacturer
operational instructions. The purpose of drying after washing is no other than to remove moisture from the products
3.Curing temperature for top coating:
The baking temperature and time depend on the nature of the finish coating. Finis coat or transparent lacquer or varnish has two types: baking type and non-baking type.
Please follow the manufacturers instructions for curing time and temperature.
The dip painting method for top coating:
The top coating is a kind of transparent varnish. Paints of a different type may be used for the finish: two-component PU paint
,one-component lacquer, baking lacquer gloss and matte.
The instructions on the finish coat application:
1.Preparation: the amount of transparent lacquer prepared depends on the amount of products.
2. Prepared lacquer must be filtered with 300mesh nylon screen.
3. Spray booth must be clean, free from dusts, The floor and the floor round the spray area must be wet to prevent dust from flying over in the air.
4. Never touch or allow any object to touch the uncured surface.
5. The operator must clean the spray gun before leaving the shift job
How to properly use and maintain the spray gun
1.Clean the gun with activator before the operation
2.The key for a successful dipping process: a. the right time (when the film is totally soaked and softened) for spraying;
a.The amount of activator applied on the film. So you have to adjust the adequate spraying amount, not too less or
b. You need also adjust the air pressure, activator flow and the width of fine spray.
c. Lower air pressure results in less activator spray and vise verse.
d. Move the gun in an adequate speed not too fast or too slow.
e. The amount of activator is related to the expansion of the film (ink layer on water). In general the bigger expansion,
the higher amount and vise verse.
f.On larger spray area (or larger film size). there must be 1/2 overlap between each passage of gun move.
This can prevent the porous defects caused by activator volatility.
g. The new comer may use wat as the activator for training purpose. After training.,the gun has to be cleaned with activator
or it will get rusty.
How to do Quality Control and Packing after finishing paint dipping process
1. The checker should timely find the problem and report to process technician to reduce the losse to maximum.
2. First check if the product is clean and dry.
3. Then check the pattern if there are holes(porous points)and cracks on the pattern.
4. Check if the trimmed surface is clean and the wave color is the same as the sample.
5. Check if there is dust, dripping and peeling on the paint.
6. The passed product can deliver to packing.
The reason and solutions for defects in the transfer printing process
1Pitting, porous holes, small bubbles or rough surface on transferred pattern surfaces.
a. Poor spray booth environment dusts in the air. Dusts on products and film surface
b. The water surface is not clean: floating impurities and remains.
c. Film did not lay evenly on water. Bubbles exist between film and wat surface.
d. Water temperature is too high. The compress air is not clean, the air is mixed with moisture oil and other Impurities (the film ink would not
be fully activated and there are water drops and oil drops on the film).
e. Not enough activator sprayed or unevenly sprayed.
f. The activator evaporated too fast: activating time is not enough. The film ink has not been activated to oily state(ink peel on the
pattern: During the transfer printing process, the wat should be expelled from between the product and ink.
The not fully activated ink may hinder expelling of water).
g. The dipping angle(normal 45°) is not correct or dipping too fast. That caused bubbles and water drops enrolled in between the product
and the pattern ink.
a. The spray room must be clean. Spray wat on the ground to prevent dusts from bying over. Clean dust from product surtaces and work table.
Do not allow dusts g on ink surface.
b.Wipe with a scape the remains away from wat surface
c. Pull the hydro dipping film gently from one end of the tank to the other at an angle of 45° (to remove any impurities and bubbles on water)
d. Check the water temperature. Experiences tell 25℃-30℃ is a right temperature, Install a water separator to the air compressor.
Disconnect the spray gun tube and clean away moisture and oil drops inside the tube to ensure cleanness of the compress air.
e.Adjust air pressure, atomization value to increase activator flow. Ensure there is 1/2 overlap between the spray passages
(never spray repeatedly on the film).On a fully activated ink layer.you may find oily light glimmering.
f. Change the activator from the fast-dry type into slow-dry. Adjust the spray gun to increase activator flow. Reduce the gun moving speed. Wait until the pattern ink fully activated to oily state.
g. Adjust the dipping angle to 45ºLower the product down gently and slowly to hydrographics tank so as to remove air bubbles from between the product and ink layer.
2.Obvious winkles and overlaps at corner position after dipping Reasons.
a. Water temperature is too low. (This causes the film not fully soaked or softened)
b.Soaking time(the time of film laying on water)is not enough(this causes the film not fully softened.
c. Too early to spray activator to the film(This causes the tension of the ink layer and that of the ground film is not equal.
The ink layer is shrunk with winkles on surfaces)
e.The pattern ink has not been activated to oily state(This causes the ink peel to appear on pattern surfaces)
a.Raise the wat temperature to about 25℃-30℃
b.Leave the film on water longer(the soaking time is about 120″ at 25℃water temperature).To see if the film is fully
soaked or not, you may make a small test as follows: spray activator on a corner of the film. If the sprayed area appears no winkle and
it is slightly stretched, then the soaking time is ok.
c.Do not spray until the film is completely softened and the surface tension is OK uniform.
d.Do not dipping until the film ink is completely activated.
3. The pattern layer peeled off and the ground layer appears: the pattern wave is blurred;
the waves appear broken; the pattern appears different in wave color shade
a. Activator sprayed too much (Over applied activator will cause slipping between the ink layer and the ground film. The of the pattern will be distorted because of such slipping).
b. The primer is too hard or over-cured(The over-cured prime is resistant to activating effect and reduces the surface between the ink layer and the ground material and will lead to the patten deformation from slippage and shrinkage).
c.Soaking time too long(The ground film will be dissolved because of too long soaking time. Then the ground film losses function to support the ink pattern. The resultant pattern will be distorted or appear broken and over-stretched.
d.The air flow of spray gun is too strong(The air flow blows the pattern disorder).
e.Activated time too long. (An over-activated ink pattern is floating and moving on water and the resultant picture on the product is blurred, unclear).
f.Solubility of the activator is not enough. The film ink has not been fuly activated. (This may led to discontinuous pattern waves and over-stretched pictures).
g.Dipping is not correct(This may lead to pattern shade and color difference)
a. Adjust air pressure and atomization value to reduce activator flow.
b. Choose the right primer. Adjust the hardness and curing of the primer.
c. Reduce the soaking time (120seconds at 25℃ water temperature) to ensure the film is not over-dissolved.
d. Adjust air pressure of the spray gun. The air flow should not be so strong as to blow mess of the pattern.
e. In general, dipping should start in 60 seconds after activator spraying.
f. Change the activator with higher solubility. Anyway, the solubility of an activator should not be adjusted too high)
g. Dip correctly. The correct start position is always where activator spray starts first and dipping at 45°(This is to ensure uniform waves and color shades of the pattern).
