What is offset printing?
The name offset has been transferred to Turkish from the English word "OFF-SET" and allows printing on paper and paper-like materials up to a certain weight. Today, it is the most preferred printing system for printed products such as books, magazines, newspapers, brochures and business cards. Offset printing is the preferred method for printing daily newspapers, especially since many products can be printed at once.
One of the newest printing methods, offset printing, the image to be printed is drawn with oil-based ink on flattened limestone. After this process, the special solution applied is absorbed by the areas where the image is not included and does not penetrate the oily areas that make up the image.
Offset printing, a flatbed printing method, uses hand-made or manufactured molds. Although the cost of ready-made molds is slightly higher, the quality is higher than that of handmade molds. In other words, choosing a die made for offset printing ensures a better quality print.
The offset printing method is based on the flat printing offset method in the production process. The image is transferred over flat metal onto an offset shaft made of special high-quality rubber. Then that image is transferred to the paper on the shaft. Offset machines are able to execute order details and half tones very accurately. The basis of a full-color image is four colors - yellow, blue, violet and black. It is not possible to change the layout during printing, since the forms are used in printing. In this regard, all details must be clarified and confirmed before the order is sent to the printing house for printing. Offset machines are able to execute order details and half tones very accurately. The basis of a full-color image is four colors - yellow, blue, violet and black.
Uv printing U.V (ultraviolet) printing is a new printing technology that has appeared recently. This technology is considered to be very long-lasting and high-quality compared to digital printing. One of the main advantages is that it is possible to print on any object through UV printing, regardless of the material. Similar sublimation printers are very popular and widely used today. However, when sublimation is printed, sublimation technologies are not used on any type of material like UV printing equipment, only sublimation color transfer. it is possible to print on receptive materials. In addition, UV print is of better quality and lasts longer. .
What are the differences between offset printing and other printing?
Differences between digital printing and offset printing
Digital printing is a type of printing in which the paint is in direct contact with the surface and does not require pre-printing forms (cliché). Today, digital printing is the most cost-effective printing method in the price category.
Digital offset printing is the two most commonly used methods for commercial printing projects. Although they produce similar results, the two methods are quite different and best suited for different project requirements. Digital printing is a printing process where toner sits on top of a sheet of paper instead of being absorbed. The printing process uses a combination of blue, magenta, yellow and black dots to create an image. This is usually used for short jobs using a laser or inkjet printer.
What are the working principles of offset printing?
If we look at the stages of offset printing, there are 2 different types of offset printing depending on the type of paper used:
The first type of printing is used for high-volume printing on special roll papers. Newspapers, magazines, notepads and diaries are prepared by this method. Roll printing is the cheapest type of offset printing.
The second type of printing is used in the preparation of various products of medium circulation. Ordering offset printing goes through 4 stages:
1. Preparation of the print form. This stage is the most painstaking and time-consuming stage. Modern technological equipment allows this stage to be carried out in a shorter time. This process happens like this – The mock-up file is sent to the printing equipment through a special RIP program, and the equipment prepares a color mock-up of the order on an aluminum sheet.
2. Printing. The speed of modern offset printing equipment can reach 10,000 prints per hour. It should be noted that double-sided printing is not possible with offset equipment. Therefore, when preparing such orders, first one side is printed and then the second side is printed.
3. Drying of paint and product.
4. Other polygraphic works. (folding, folding, lamination, embossing).
