Screen Printing: Print Patterns On Silicone Products

Screen printing is a printing technique where a mesh is used to transfer ink (or dye) onto a substrate, except in areas made impermeable to the ink by a blocking stencil. A blade or squeegee is moved across the screen to fill the open mesh apertures with ink, and a reverse stroke then causes the screen to touch the substrate momentarily along a line of contact. This causes the ink to wet the substrate and be pulled out of the mesh apertures as the screen springs back after the blade has passed. One color is printed at a time, so several screens can be used to produce a multi-colored image or design.

The technique is used not only for garment printing but for printing on many other substances, including decals, clock and watch faces, Silicone, and many other products. Advanced uses include laying down conductors and resistors in multi-layer circuits using thin ceramic layers as the substrate.

What Is Screen Printing?

Screen printing is the process of transferring a stenciled design onto a flat surface using a mesh screen, ink, and a squeegee.

Fabric and paper are the most commonly screen-printed surfaces, but with specialized inks, it’s also possible to print onto wood, metal, plastic, and even glass. The basic method involves creating a stencil on a fine mesh screen, and then pushing ink (or paint, in the case of artwork and posters) through to create an imprint of your design on the surface beneath.

The process is sometimes called ‘silk screening’ or ‘silk screen printing’ and while the actual printing process is always fairly similar, the way the stencil is created can vary, depending on the materials used. Different stencilling techniques include:

Using masking tape or vinyl to cover the desired areas of the screen.

Painting the stencil onto the mesh using ‘screen blockers’ such as glue or lacquer.

Using a light-sensitive emulsion to create a stencil, which is then developed in a similar way to a photograph.

Designs made using the screen printing technique may use just one shade of ink, or several. In the case of multicolored items, the colors must be applied in individual layers, using separate stencils for each ink.

A Brief History Of Screen Printing

Screenprinting originated in China (around AD 221) as a way of transferring designs onto fabrics.

Following this the Japanese began using simple stenciling techniques as a way to create imagery. At this time stencils were cut out of paper and the mesh was woven from human hair. Stiff brushes were used to force ink through the mesh onto the fabric.

How Does Screen Printing Work?

Screen printing can be done by hand or using a machine but the basic process is always the same. The differences can be of the type of ink used, its rendered effect and the printed surface. Below is the screen printing process step by step:

What Are the Steps of Screen Printing?

Screen printing is a popular printing method that’s done in a few easy steps:

  1. Step One: Your design is put on a screen.
  2. Step Two: Thick green goo called emulsion is spread over the screen.
  3. Step Three: Before the emulsion hardens, a machine goes over it with UV-shielding ink.
  4. Step Four: The emulsion hardens and a negative image is displayed.
  5. Step Five: Colored ink is spread over the screen and applied via a printing machine.
  6. Step Six: The screen-printed item is ready to go!

The reason that it’s called “screen printing” is because it involves the use of screens, which we hope isn’t that surprising. It would be great if manufacturers had giant pens they could use to draw a company’s logo in puffy ink on their items, but until they do (and until they make enough to handle a giant production like five thousand baby bibs), manufacturers need a way to force ink onto the item in the shape of a specific design.

Different Types Of Screen Printing Methods

There are six different types of screen printing processes. Since different techniques will provide different results, it is important to understand the different types.


The most common screen printing technique is spot colour screen printing. Spot colour screen printing uses the ink’s stock colour by printing it through the stencil of the mesh. This technique produces a vibrant solid spot of colour. It is much simpler to use as compared to other screen printing methods. It can be an excellent option for printing on t-shirts, jackets, and hoodies, for example.


In halftone printing, single colours in gradients are printed. The entire process uses a single colour of ink, and this colour gets half-toned, resulting in a different shade when looked at from a distance. This technique is best used to obtain the multi-colour printing look without actually doing it. In addition, it is a cost-effective method since only one colour of ink is used.


Grayscale printing is an excellent method of printing full-colour images as one colour grayscales or halftones. The print will look more detailed if the halftone has more dots. It is not a black and white technique; instead, it pulls out the CMY or RGB or colour scales only but in shades of grey. Grayscale printing is one of the most cost-effective screen printing techniques, often used for printing black and white designs onto fabrics.


Duotone printing uses the combination of two halftones for printing the same image with two colours. First, a black halftone is printed with black ink, and then a second halftone is printed with colour ink. This technique is similar to sepia-toned print in photography. It provides a sophisticated and artsy effect.


It is the most complex screen printing technique. It involves the four basic colours – cyan, magenta, yellow and black. These four colours are combined to produce the required colour tones. It can be done manually but preferably should be done automatically for best results.


The simulated printing process combines the four-colour printing process with spot colour printing. Since this technique is useful for both lighter and darker shades, it is versatile and popular with people looking to produce photorealistic print detail.

Advantages And Disadvantages Of Screen Printing

Advantages of Screen printing

When considering using screen printing technology, it’s worthwhile thinking about its benefits, of which there are many.

  • VERSATILITY: One of the main advantages of screen printing is its versatility. It can be used on any type of fabric, plastic, wood, glass or even metal. Plus, multiple colours can be used. There is almost endless design freedom when using screen printing.
  • DURABILITY-Long lasting: Compared to other printing methods, screen printing can apply a heavy ink coverage, resulting in a durable design. Additionally, certain coatings and additives can make the ink resistant to UV rays, scratches, moisture and chemicals, allowing screen-printed products to be used outdoors and in harsh environments without fading.
  • VIBRANCY OF INK COLOURS-Great Finish: The vibrant and bolder colours produced by screen printing is quite tricky to replicate with other techniques. For multiple colour designs, separate layers are used, which allows each colour to preserve its actual brilliancy.
  • COST-EFFECTIVE: Screen printing is a cost-effective method in the longer run. Once the set-up is done, it is relatively quick and easy to print items at high volumes. So, it’s safe to say the more you print, the cheaper the unit cost becomes.
  • EXCEPTIONAL SPEED AND EFFICIENCY: Screen printing is one of the most efficient and fast printing techniques once a screen has been created. It is an excellent option if the same design is to be printed over and over again.
  • STRAIGHTFORWARD PROCESS: The screen printing process is fairly straightforward, whether it is automated or done manually. Moreover, the required tools are also not hard or costly to replace.

Disadvantages of screen printing

  • It has a much higher initial setup cost than digital printing and takes more time.
  • More limited colour ranges are available
  • The amount of ink used can make the design look as if it is raised from the print material
  • More money for multiple colors
  • Not practical for small orders
  • Relative Complexity

Choosing The Right Substrate For Screen Printing

The choice of mesh count, thread size, and open area will depend on the type of substrate. For example, a coarser mesh (with a lower thread count) is typically used for printing on thicker substrates, such as cardboard or poster board. Conversely, a finer mesh (with a higher thread count) is typically used for printing on thinner substrates, such as paper or fabric.

Equipment And Materials Required For Screen Printing

  • A screen
  • A squeegee
  • A printing table with hinges
  • Stencil material
  • Registration plastic
  • Water-based screen-printing inks
  • Somewhere with a strong hose for screen cleaning

Tips For Achieving High-Quality Screen Prints

  • Properly prepare the ink: An ink’s quality is crucial to the quality of the final image produced. If it’s too thin or too thick, the printing quality is difficult to regulate. Should the ink not be of print-quality consistency, you can add products to help thin or thicken the ink.
  • Ensure the artwork is ready for screen printing: Just as important as preparing the ink, setting up the artwork correctly for your screen printer is a must. The best way to do this is to have the image copied onto a transparent layer, which you can have a local printer do for a very small fee.
  • Gather all the required materials first: With the artwork and ink prepped, gather the rest of the materials necessary for screen printing:
  • Keep the screen as tight as possible: A loose screen can ruin the screen printing process as it will compromise the final printed image. If the screen isn’t tight, the image will “bleed” as the image area accidentally becomes a moving target.
  • Watch out for mesh count: Did you know that every screen has a different mesh count? Higher mesh counts release less ink through screen and onto the print, while lower mesh counts work the opposite way.
  • Know your color-based limitations: One-color designs are often best for screen printing materials quickly. While multiple colors are possible, the more complex your design is – both shape, size, and color – the more careful you need to be when multiple colors.
  • Thinning out with multiple colors and inks: For the ambitious printer, we’ll help you out too, though. When applying multiple colors, it’s important to understand how muck ink should be applied. The first color added is the one that needs to penetrate the deepest into the material.
  • Platen: don’t move! When pressing the image, the platen can’t move. At all.
  • A straight, sharp squeegee: To help the ink pass through the screen and reach the material, a squeegee is required. One thing you need to be sure of is the squeegee is sharp and straight.
  • Take your time to save time: Screen printing is an art form just as much as a manufacturing process. In order to save time, take your time when screen printing materials. As you’ve already seen, this is a complex process that requires patience, a careful eye, and an undistracted mind. If you rush through screen printing, chances are you’ll have to repeat the process over again.
  • Learn about curing: After being screen printed onto your desired material, ink needs time to settle, or “cure.” Despite popular belief, you cannot speed up the curing process with higher temperatures or different settings. You just need to wait it out.
  • Pressure and number of strokes: The type of pressure applied when screen printing depends on a few factors: the thickness of the ink, the material’s color, style, and consistency, and the complexity of your art design.
  • Cleaning the machine and its materials: Maintaining a clean screen printer and all the materials as you go is very important. As the printing process progresses, keep an eye out for ink that has “bled” onto areas of the screen printer where the ink shouldn’t be.
