In polyester printing mesh, what are the requirements and what are not?
Definition: polyester printing mesh, also known as stenciling or silkscreening, is a printing method in which a screen is placed on a finely woven screen, and the screen is stretched and fixed on the frame. The material to be printed is placed under the frame, and the liquid ink is pressed down by a "scraper", passing down through the porous material, and transferring the image of the ink-transparent printing plate to the material to be printed. Screen printing differs from other forms of printing in that it uses a pigment ink to form a thick layer of ink on the paper surface, resulting in bright, vibrant colors.
1. Carefully select the ink, consider how the ink reacts with the paper, and how you want the ink to look when overprinting. The choice of inks is very wide: paper inks, vinyl inks and UV inks. Possible printing effects include matte or glossy, gold
It is an ink, varnish, embossing varnish, phosphorescent ink, white ink and fluorescent ink.
You can print images that are lighter than paper, such as white ink on black paper. When the transparency of the ink is required, ethylene
Base inks provide good results. However, it should be remembered that the imprint will
Not opaque.
For satellite softness, star or paper, consider using infrared screen printing. Traditional printing with vinyl ink screens and in combination with a drying oven is also suitable for printers who want to fully trust themselves. The screen printing process involves manual operations and relies on the printer's expertise to know how to best use a combination of pressure, ink, screen, etc. to better display a picture. Silkscreen can be used on crepe paper. The screen printing press can print a 1.5 cm thick substrate.
2. Do not screen complex color graphics. The screen printing process can only print one spot color at a time, so each color of the graphic must be used.
Separate wire mesh.
Don't forget to trap when preprinting. In fact, as in other processes, the color registration is not so fine.
Do not select texture paper when detail is required. For precise drop inks, the screen is required to be in intimate contact with the substrate, and if textured paper is used, the contact is affected. If necessary, you can remove the texture on the image beforehand. ·
When designing your artwork, don't overlook the technical limitations you may face when producing. Clear outline and thick line effect
Better. The minimum detail allowed for screen density is 0.3pts, depending on the press and the process being taken.
Do not test, please do not screen on light paper, because the ink may cause paper deformation or pleating
