What is silk printing?

Screen printing (screen printing) is a penetrating printing method. The printing mold is usually composed of a polyester mesh stretched over a rectangular frame made of wood or aluminum alloy. When printing, people put ink into the frame and brush it with a brush. a rubber blade. Under the pressure of the knife, the ink will penetrate the mesh cells and transfer (stick to) the surface of the material below, creating a printed image.

In this article we will discuss how we carry out the screen printing process in Dallas for providing the service of screen printing.

Process of making silk screen printing molds (screen printing)

At this point, we begin to ask a new question: how to take copies?

The drying process includes:

+ Apply a layer of glue to the mesh surface and take a photo of the glue drying plate.

+ Place screen printing film (usually black and white laser tracing paper) close to the mesh surface. Ballast on the surface

 Film a glass plate to ensure good contact with the sputum.

+ Lighting onto the mesh surface through film. Under the influence of light, the glue layer will harden. In places where there are words or images on the film, the light will be blocked by the ink layer there and the glue layer below those words will not be illuminated -> will not be solidified.

+ Wash the frame with water, the areas where the glue was exposed to light have hardened and adhered tightly to the grid surface –> all the grid cells are sealed, only in areas with images and writing the glue has not hardened and become damaged. Water washes away. When printing, the ink will penetrate these areas and print the image on the paper as if it were on film.

Silk printing steps:

* To print on t-shirts, we first need a printing table with hinges

* After that, remember to clamp the silk frame firmly. If it’s loose, the print will be lopsided and distorted

* Then proceed to mix the ink

* The next part is adjusting the position, which means making sure that when printed, the image must be in the correct position on the printed product. 

* You can use the butterfly wing type for the armrest or you can guard it in the following way:

+ First, stick the armrest on a piece of cardboard, attach a sheet of test paper to it, and secure it with tape.

+ Place the paper on the printing table, lower the silk frame and pull it back and forth to the cover to align the position of the printed sheet (by looking through the frame because at this time the ink has not been poured in so you can see). After aligning, use tape to secure the cover piece. Once aligned, proceed with printing. Put ink into the frame (be careful not to let the ink spill out). The printing process is: put the product in, use both hands to lower the frame, brush the ink once, then lift the frame, pick up the product and you’re done ( pulling technique depends on the product, sometimes you have to pull 2 ‚Äč‚Äčtimes). times – once to spread the ink onto the frame while raising the frame, the second time to pull the print onto the product when the frame is lowered). Note that the frame must be positioned so that it is 3-5mm open from the table surface, not close to the table surface. After printing a few dozen times, use a cotton ball soaked in oil to wipe the underside of the frame to prevent the ink from smudging. Wait for the glue on the product to dry and we have a complete screen-printed product.
