Although it is of course possible to use Stenter's custom offset printing technology to make paper signs on thick cover paper, the more common methods currently are screen printing and digital inkjet printing.

If you want to print a single or two-color job, you may need to contact a screen printing company. Screen printing uses metal or synthetic screens, and a squeegee is used to press the thick ink through. The open areas on the screen allow ink to pass through to the printing substrate, while the blocked areas on the screen prevent ink from passing through the screen onto the paper.

Screen printing is quite expensive to set up, so the longer the printer runs, the better. For example, if there are 10 printed editions, a supplier charges more than $8.00 per sign, but if there are 100 printed editions, the charge per sign is only $2.00. Long-term operation can significantly reduce unit costs.

Some screen printing companies do not calculate the background color (such as white or yellow), but only charge for each additional color of the type and graphics printed on the logo. One thing to keep in mind is that screen printers usually provide you with a list of standard colors (for example, a specific blue or red), but if you want to match a specific PMS color, they will You charge additional fees.

Another technology used by the Flat Screen Printing Machine for shorter print runs (such as one or five copies) is digital inkjet printing, which uses four process colors to simulate the full color spectrum. For signs that incorporate photos into the design, digital inkjet is also a good choice. With the increasing use of UV ink technology, it is possible to produce political signs that can withstand the sun and rain.
