What is Silk Screen Printing?

In screen printing, a screen mesh is used as plate to transfer the ink to the targeted printing area of the paper box. Meantime, the blank area on the paper box remains blank by applying an impermeable coating on the mesh to prevent the inks from passing through. A blade or squeegee is moved across the mesh to force the ink into the small opening first, then the ink is transferred to the paper box by a momentary touch. One color is printed at a time, so several screens can be used to produce a full color printing paper box.

The screen printing is also referred to as silkscreen printing because silk was used initially to make the mesh at the early stage. Afterward, polyester was invented to replace the silk to improve the printing quality and to reduce the cost. Currently, the polyester is the most popular mesh in general use. Other materials include nylon and stainless steel. In the printing of the custom paper box, the mesh size is an important factor, which will determine the outcome and look of the finished design on the material.

The Process of the Screen Printing

The screen printing consists of 2 main steps, prepare the screen mask, then do the printing.

 

  • A screen mesh is stretched across an aluminum or wooden frame that matches the size of the printed paper box.
  • A coating of photosensitive substance is applied on the screen mesh.
  • A positive mask is used to cover the parts to be printed such as the texts and images, and then the screen mesh are exposed to the UV light. The coating on the blank parts not to be printed become hard.
  • When the screen mesh is flushed with water, the coating on the printing part is washed away.
  • Once the mesh is dried and inspected, the screen mask is complete.
  • The screen mesh is placed on top of the paper box to be printed.
  • The ink is applied across over the screen and the ink passes into the small openings on the mesh.
  • The mesh touches the surface of the paper box momentarily and transfers the ink to the paperboard by moving a blade or squeegee across the mesh.

Vantage Point of Screen Printing

Because the ink is forced to pass through the openings on the screen mesh to transfer the image during the screen printing process, the ink layer on the paper box would be quite thick. It means that the screen printing can be applied on any kinds of paperboard, thick or thin, glossy or matte, with a smooth or rough surface.

Custom Screen Printed Paper Box

90% of our paper boxes are litho printed, or UV printed. But when we come to a custom paper box made of a thick paperboard, like black specialty paper or kraft paperboard, those printing methods don’t work any more because the inks layer is too thin to be visible. For these special paperboard, we usually use the silk screen printing method to do the printing.
