Working principle of Cap Screen Printing Machine

 

Taking the commonly used hand-shaped flat screen printing machine as an example, the working principle of the screen printing machine can be described as follows: the power is transmitted through the transmission mechanism, so that the squeegee squeezes the ink and the screen printing plate in motion, so that the screen The printing plate and the substrate form an impression line. Because the screen has tension N1 and N2, it generates a force F2 on the squeegee. The resilience makes the screen printing plate not contact the substrate except the impression line. The ink is in contact with the substrate. Under the action of the squeezing force F1 of the squeegee, the printing is leaked from the moving embossing line to the substrate through the mesh.

 

During the printing process, the screen printing plate and the squeegee move relative to each other, and the squeezing force F1 and the resilience F2 also move synchronously. Under the action of the resilience, the screen returns in time to disengage from the substrate in order to avoid The blot is dirty. That is, the screen is constantly deformed and rebounded during the printing process.

 

The squeegee is separated from the substrate together with the screen printing plate after the one-way printing is completed, and at the same time, it returns to the ink to complete a printing cycle. The distance between the upper surface of the substrate and the reverse side of the screen printing plate after the ink is returned is called the same-page distance or screen distance, which should generally be 2 to 5 mm. In manual printing, the technique and proficiency of the operator directly affects the formation of the impression line. In practice, screen printing workers have accumulated a lot of valuable experience, which can be summarized into six points, namely, to ensure the straightness, uniformity, isometric, equalizing, centering and vertical edge in the movement of the squeegee. In other words, the squeegee board should move straight forward during printing, and cannot move left and right; it cannot be slow in front and fast in the back, slow in the front and slow in the back or suddenly slow and fast; the inclination angle to the ink board should remain unchanged, and special attention must be paid to overcome the inclination angle The common problem of increasing gradually; the printing pressure should be kept even and consistent; the distance between the squeegee and the inner sides of the screen frame should be equal; the ink plate should be perpendicular to the frame.

 

The history of Cap Screen Printing Machine

Screen printing is an ancient art form. An early version of the technique was first pioneered in China, around AD 950, as a method of printing patterns onto fabric. Several centuries later, Japanese artisans adopted the practice to transfer designs onto paper and fabric, using a stiff brush to push ink through a mesh screen woven from human hair.

 

Screen printing arrived in Europe in the 18th century, but it was slow to catch on as a fabric printing method owing to the high cost of silk mesh at the time. Once the Silk Road made imported silk more affordable, screen printing gradually became a popular — and profitable — way to print fabric. By the early 20th century, printers had developed photo-sensitised emulsions, allowing artisans to create complex stencil designs much more easily.

 

In the 1930s, artists began experimenting with screen printing as an artistic medium, naming their new-found form 'serigraphy' to distinguish it from industrial printing. By the 1960s, artists such as Eduardo Paolozzi and Andy Warhol were using screen printing to create fine art. Dubbed 'pop-art', the artist used screen-printing to create multiple copies of a single image, essentially questioning what constituted fine art. Warhol's famous Marilyn Diptych is perhaps the best-known example of screen printing as an artistic form.

 

Nowadays, screen printing is used both as an artistic medium and as a commercial printing process. One stencil can be used to reproduce the same design hundreds — or even thousands — of times, so it’s a brilliant technique for producing large orders of custom clothing.

A guide to Cap Screen Printing Machine equipment
 

 

1. Screen printing Press

While it is possible to screen print with just a mesh screen and a squeegee, most printers prefer to use a press, as it allows them to print lots of items more efficiently. This is because the press holds the screen in place between prints, making it easier for the user to swap out the paper or clothing being printed.

There are three types of Cap Screen Printing Machine: manual, semi-automatic, and automatic. Manual presses are operated by hand, meaning they’re quite labour intensive. Semi-automatic presses are partially mechanised, but still require human input to swap over the items being pressed, while automatic presses are completely automated and require little to no input.

Businesses that need to print items in large quantities will normally use a semi- or fully automatic press, as this allows faster, more efficient printing and minimises mistakes. Smaller companies, or those who do screen printing as a hobby, might find that a manual table-top press (sometimes called a 'handbench' press) is better suited to their needs.

2. The Inks

The ink, pigment or paint is pushed through the mesh screen and onto the item being printed, transferring a coloured imprint of the stencil design onto the product.

There’s much more to choosing an ink than just picking a colour. There are lots of specialist inks, which can be used to create different effects on the finished product. For instance, a printer may use glittery inks, texturised inks, or puff inks (which expand to create a raised surface) to create a unique look or feel. The printer will also take into account the type of fabric being screen printed, as some inks will work better on certain materials than others.

When printing clothing, printers will use a type of ink which becomes machine washable once it has been heat-treated and set. This produces a colourfast, long-wearing item that can be worn again and again.

3. The Silk Screen

The silk screen in silk screen printing is a metal or wooden frame with a fine mesh fabric stretched over the top. Traditionally, this mesh was crafted from silk thread, but nowadays this has been superseded by polyester fabrics, which offer the same performance for a lower price. The thickness and thread count of the mesh can be chosen to suit the texture of the surface or fabric being printed, with smaller spaces between threads allowing for greater detail in the print.

Once the screen has been coated in emulsion and exposed, it is ready to be used as a stencil. After the screen printing process has finished, it can be washed and re-used.

4. The squeegee

A squeegee is a rubber blade attached to a long wooden, metal or plastic handle. It’s used to push the ink through the mesh screen and onto the surface being printed. The printer will usually pick a squeegee that is a similar size to the frame of the screen, as this will give better coverage.

A firmer rubber blade is better for printing intricate designs with lots of detail, as it ensures all the nooks and crannies in the stencil receive an even layer of ink. A softer, more yielding rubber squeegee is often used when printing less detailed designs, or when printing onto fabric.

5. The Washing Station

The screens need to be washed to remove all traces of emulsion after use, so they can be reused again for future prints. Some larger printworks may use large tubs of special cleaning fluid or acid to remove the emulsion, while other printers simply use a water trough or sink and a power hose to clean their screens.

The Cap Screen Printing Machine process step
 

The design is created
To start, the printer takes the design they want to create on the finished product, and prints it out onto a transparent acetate film. This will be used to create the stencil.

 

The screen is prepared
Next, the printer will choose a mesh screen to suit the complexity of the design, and the texture of the fabric being printed. The mesh screen is then coated with a layer of light-reactive emulsion, which will harden when developed under bright light.

 

The emulsion is exposed
The acetate sheet featuring the design is then laid onto the emulsion-coated screen, and the whole thing is exposed to a very bright light. The light hardens the emulsion, so the parts of the screen which are covered by the design remain in liquid form.

If the final design is going to include more than one colour, then a separate screen must be used to apply each layer of ink. To create multi-coloured products, the printer must use his skill to design each stencil, and line them up perfectly to ensure the final design is seamless.

 

The emulsion is washed off, creating the stencil
After the screen has been exposed for a set time, the areas of the screen not covered by the design will have turned hard. Any unhardened emulsion is then carefully rinsed away. This leaves a clear imprint of the design on the screen for the ink to pass through.

The screen is then dried, and the printer will make any necessary touch-ups or corrections to make the imprint as accurate as possible to the original design. The stencil is now ready to be used.

 

The Item Is Prepared For Print
The screen is then placed on the printing press. The item or garment being printed is laid down flat onto the printing board, underneath the screen.

There are a number of different presses, including manual and automatic styles, but most modern commercial printers will use an automatic rotary carousel printer, as this allows several different screens to work at once. For multicoloured prints, this sort of printer can also be used to apply the separate colour layers in quick succession.

 

The ink is pressed through the screen onto the item
The screen is lowered down onto the printing board. Ink is added to the top end of the screen, and a squeegee is used to pull the ink along the full length of the screen. This presses the ink through the open areas of the stencil, imprinting the design on the product underneath.

If the printer is creating multiple items, then the screen is raised and a new garment is placed onto the printing board. The process is then repeated.

Once all the items have been printed and the stencil has served its purpose, the emulsion is removed using a special washing fluid so the mesh can be reused to create new stencils.

 

The product is dried, checked and finished
The printed product then passes through a dryer, which 'cures' the ink and creates a smooth, colourfast finish. The final product will be checked and washed thoroughly to remove any residue, before being passed on to its new owner.
