Printing is the process of transferring an image, text, or other information from one surface to another by applying ink, paint, or another medium to the surface.
There are many different types of printing technologies that are used to create a variety of products. In the office, one might use laser or inkjet printing. In the creative industry, sublimation printing is used widely. For mass production, screen printing is a very common method.
Let’s discuss all of them one by one so you can choose the one that is most relevant to your interests.
1. Sublimation printing:
You must be thinking what is sublimation printing? Sublimation printing is a printing process that uses heat and pressure to transfer ink onto paper, plastic, fabric, or another material. This process uses ink-receptive materials instead of the traditional plate-making process of lithography. The inks are fused into the material and become part of it.
The advantages of sublimation printing are that it can be used with any type of substrate, offers vibrant colors and detailed images, and does not require screens or plates for each color. The disadvantages are that it may not work well with complex shapes or small details and can only be used on certain types of products such as polyester fabrics or ceramics.
2. Laser printing:
Laser printing is a type of printing that uses a laser beam to produce an image on paper. The benefits of laser printing are that it can produce high-quality images quickly and at lower costs than other methods. A laser printer consists of a computer, a scanner that converts the image into digital data, and an output device that projects the data onto paper.
In this way, it is similar to a photocopier. The computer creates the image by scanning in some type of document such as text or graphic material (for example a page from a book) and printing it out in digital form on some sort of media such as paper or transparencies. The scanner sends images to the computer, which turns them into digital information and then prints them out on the medium.
A laser printer uses a series of electro-mechanical components to produce the image on paper, including a photosensitive drum onto which images are placed and then copied from.
Laser printers have many advantages and disadvantages. One advantage is that they can print much faster than inkjet printers, this is because they don’t need to wait for the ink to dry before printing again, and some laser printers can print in multiple colors. A disadvantage of laser printing is that it uses more electricity than inkjet printing and it’s also more expensive because of the cost of the toner cartridge or drum unit.
3. Screen printing:
Screen printing is a technique for printing from a metal or plastic plate, called a screen or stencil, to the fabric. The screen is made of fine mesh cloth (typically silk) stretched across a frame and printed with an ink-blocking stencil. The screen can be used to print text, images, patterns, or other designs on paper, cardstock, textiles, and other materials.
Screen printing is often used in the production of large-format posters and signs. It also has many applications in the textile industry as it can be used to print on fabrics that are difficult to dye by other means.
The “old” type of screen printing was done with letterpress and a cloth stencil. The ink was applied through the stencil onto the cloth, then pressed. The design would be printed where the ink is blocked in between the mesh of the cloth. The second layer of ink could be printed on top to add depth and tone to an image or design. Hand-pressed screens are manipulated by hand tools such as squeegee or burr, with no rolling motion involved by pressing a roller or a machine. The screens are arranged in a frame that is covered with a sheet of cloth, painted on one side, and with openings where the ink will exit. The stencil is applied to the wet surface of the cloth and then wiped off. Ink is forced by pressure from the foot pedal through any opening in the stencil corresponding to an image or design, leaving it on whatever surface it covers. The cloth is then removed from around this first layer of screen-printed ink.
Screen printing has some advantages like the ability to print large quantities of items in a small space of time. It also has some disadvantages such as the need for high-volume production and the inability to print on both sides of the fabric.
Out of all printing types, Digital printing has become the most popular form of printing in recent years due to its low cost, speed, and versatility. It is also easier for manufacturers to produce small batches of products with digital printers because they can print one copy at a time instead of having large production runs as lithography does. The only downside with digital printers is that they are not as environmentally friendly because they require chemicals like solvents and inks that can be harmful when disposed of improperly or leaked into the environment.
