Screen printing is a versatile printing technique that allows a variety of specialty inks to be applied to a wide range of substrates. It is indispensable in projects that require a sophisticated finish. One of the most popular effects that can be achieved is fluorescence. Fluorescent printing allows you to create attractive advertising materials and packaging that stand out with intense neon colors during the day and provide a glow-in-the-dark effect under the influence of ultraviolet light. Depending on the application of the printed materials, a glowing effect can also be achieved when excited. In this case, two effects can be achieved. One of them causes that the print is not visible in daylight, but only after being illuminated by UV lamps. The second glow-in-the-dark effect is caused by prior exposure of the print with daylight, artificial or UV light. Phosphoresis printing provides a glow-in-the-dark effect of green, blue or red for several hours. Screen printing is also perfect for creating metallic effects on products such as certificates, diplomas, invitations, business cards, art prints or trading cards. The metallic gloss effect is also often used to decorate the packaging of premium products. Metallic printing allows you to achieve a gloss that imitates the appearance of metals such as gold, silver, copper or platinum. Another unique effect is the mirror effect. This method is widely used in the production of decorations, promotional materials and interior design elements, where the effect of metallic gloss is desired. A surprising effect can be achieved with thermochromic and photochromic printing. The most well-known effect is the appearance of previously invisible graphics on the mug under the influence of a warm drink. The effect can be reversible or irreversible. Thermochromic prints also allow you to monitor and indicate temperature changes, which improves product quality control. Examples of use are labels on beverages or prints on frozen food packaging. The thermochromic effect can also be used in the printing of document and product security. Thermochromic prints can be personalized, allowing the effect to be activated at selected temperatures. The ability to change color when exposed to temperature engages consumers and increases the attractiveness of advertising materials and products. Photochromic printing, on the other hand, allows you to achieve the effect of color variation under the influence of light. Variable optical varnishes used in printing are transparent or have a delicate shade, but when exposed to sunlight they become coloured or change from one colour to another. Printing with special inks also allows you to release the smell, achieve magnetic effects, and even ensure the conductivity of electricity.
