Post-it Printing Process
Although Custom Printed Sticky Notes are small, they are an indispensable part of daily life and office work. The process from a piece of ordinary paper to a finished sticky note is actually much more complicated than imagined. A high-quality sticky note needs to go through many links such as material selection, printing, gluing, cutting, and molding. Each step affects the final use experience.
The first step is to choose paper. Generally, Dowling paper, writing paper or light special paper is used. These papers have a flat surface, moderate ink absorption, and no ink bleeding or slipping when writing. In order to protect the environment, many printing factories are now beginning to use recycled paper or wood-free paper. The stiffness, whiteness, and thickness of the paper must be tested to ensure that it will not curl easily when applied.
The second step is printing. Post-it notes come in various patterns, some are simple solid colors, and some are customized with logos or patterns. When printing, pay attention to the color reproduction and color stacking accuracy. Large printing plants usually use offset printing machines for mass production, while small batch orders mostly use digital printing. Manufacturers like Dongguan Boyi Printing Co., Ltd. will confirm proofs before printing to ensure that patterns, fonts, and colors meet customer requirements.Next is the gluing process. This is the key to determining how sticky the sticky notes are. Generally, environmentally friendly water-soluble glue is used, which is evenly coated on the back through a machine, and then dried at a constant temperature. A good sticky note can be firmly attached and can be removed many times without leaving any traces.
Cutting and shaping are the last major steps. The cutting must be precise and the edges must be smooth. If it is a special-shaped sticky note, die-cutting equipment is needed to complete the special shape. After that, they are stacked, pressed, and packaged. Some customers will also customize the brand shell or print the company logo.
Behind every stack of small sticky notes is a complete printing process and meticulous quality control. From paper to glue, from color to packaging, every process affects the feel. A high-quality printing house is not only a producer, but also a design executor who turns ideas into physical objects.
