![]() ![]() The screen is first coated with a photo sensitive emulsion such as diazo photo emulsion. However, these days, polyester is the preferred fabric. The fabric initially used in ancient times was silk, giving the process its name. The screen used in silk screening is a piece of sheer fabric. How is Silk Screening Done? The Step By Step Process Step 1: Overlay Screen With Emulsion The resultant prints are soft, without any protrusions or rough finishes.įor bulk printing and high contrast simple graphics and images, silk screening is your best option. It has high colour and line precision and produces sharp and intense images.ĭigital printing, on the other hand, is more economical for fewer prints and can be done for complex images like high-resolution photographs. This makes it more suitable for simple graphic designs such as logos and text. Silk screening, as mentioned earlier, is perfect for a larger number of prints, but is limited to a maximum of 4 unique colours in the design. When you compare screen printing vs digital printing, both methods of printing have their own unique benefits and drawbacks. The resultant print can be washed and used many times (in the case of fabrics), without the image becoming dull or faded. This method of printing ensures that personalised items last longer, without the print fading or wearing off easily.ĥ. Silkscreen printing allows you to perfectly replicate your design, no matter what colours or patterns are present.Ĥ. Silk screening produces excellent quality at costs that go lower as the number of prints increases.ģ. To begin with, silk screening is perfect for large runs where there is a huge number of prints to be made like tshirt printing.Ģ. There are many benefits of silk screen printing, which is why this method is so popular.ġ. With advancements in the screen printing process, better thick inks and machinery have been developed that allow us to produce images of high quality. The ink color is then transferred onto the medium material with the help of a scraper tool. This printing frame is placed on top of the medium, and various screens with a specific mesh count having different colours to be printed are placed on top of each other in layers. This method involves the creation of a printing frame in automatic machines to help pull the ink and transfer the printed image from a sheet to the final medium or substrate material.

It is a very old technique, dating back to at least a 100 years in the printing industry. Had overlapping "courtyards" (for the cases where the silk line are smaller) - and this resulted in the production files being automatically adjusted to avoid having silk on the pads (these adjustments may be made by the PCB design tool, and are in my experience also applied by the manufacturer).Silk screening, or silk-screen printing (serigraphy), is one of the most preferred printing techniques by printing companies.Not respect design rules if he did have actual courtyards.Not use courtyards and only had silk lines, using them as some kind of courtyard.So it seems that the designer may have done one or more of the following: The picture has some cases where the shared lines are larger (around the crystal) and other cases where the lines are smaller (between the columns on the far right). You can confirm that this is inline with my explications above.īen Voigt's remark caused me to look in more detail. I haven't updated the outlines of all my components yet - the lines in blue are the silkscreen lines, the lines in grey are the courtyards. The silk outline for resistors, diodes and capacitors are not rectangular either.īelow you can see a detail of one of my boards. In IPC-7351B the courtyards were rectangular, they can now be "arbitrary" and more closely follow the component's outline. The silk outlines and courtyards are suggested by the IPC-7351C document. So the silk line must be a bit on the inside of the courtyard to make sure that there is some space between the silk lines of two different components as you see on boards. ![]() Courtyards can touch each other, so if the silk outline would be the same, two resistors would have a shared silk line if their courtyards touch. Generally the silkscreen outline is slightly smaller than the courtyard outline. ![]() The silkscreen is visible on the board, the courtyard is a design concept and visible only in the PCB Design Application. The courtyard and the silkscreen are different things. ![]()
