The role of digital printing plates in the printing process in 2023

• Offset printing process

Offset printing uses printing plates to transfer the image to paper or other substrates. Plates are usually made of a thin sheet of metal, but in some cases, plates are made of plastic, rubber, or paper. Metal plates are more expensive than paper plates, but they last longer, produce high-quality images on paper, and are more accurate than plates made of other materials. An image is formed using a photomechanical or photochemical process during one stage of production. Known as a preprint, it is burned onto a printing plate. A page is made for each ink color in the printing job.

The printing plates are attached to the plate cylinders on the printing machine. Ink and water are applied to the rollers. The image on the screen is transferred to an intermediate cylinder and then to the plate, where the ink adheres only to the imaged areas of the screen. The ink is then transferred to the paper that passes through the press.

Although advanced commercial printing companies are moving towards digital print However, many printers still use the tried-and-true method of offset printing, which has been the standard in commercial printing for over a century. Although the quality of digital printing, especially in Book publishing Much improved, metal plate offset printing still offers the highest possible print quality.

Before printing, plating decisions

A print job printed with only black ink requires only one page. A print job printed with red and black ink requires two pages. In general, the more pages for print If a work is required, it has a higher price.

Things get more complicated when color photos are involved. Offset printing requires separating color images into four ink colors – cyan, magenta, yellow and black. The CMYK files are eventually converted to four pages that run simultaneously on a four-cylinder press. CMYK is different from the RGB (red, green, blue) color model you see on your computer screen. Digital files are reviewed and adjusted for each print job to minimize the number of pages needed to print the project, and color images or complex files are converted to CYMK only. In some cases, there may be more than four pages. Additional pages are required if a logo must appear in a specific pantone color or if metallic ink is used in addition to full color images.

Imposing license plates and fees

Depending on the size and quantity of the final printed product, multiple copies of the file may be printed on one large sheet of paper and then cut to size. When a print job is printed on both sides of a sheet of paper, the prepress department may force the image to print all the fronts on one page and all the backs on the other, known as sheets. This imposition is used when the paper has a different texture on one side than the other, or when the print job consists of the same front with multiple copies on the back.

The front and back can be depicted on the same page in a work-and-turn or work-and-turn design. Of these approaches, sheet metal is usually more expensive because it doubles the number of sheets. Depending on the size of the project, the number of inks and the size of the paper sheet, the prepress department will choose the most efficient way to impose the project on the plates. Metal plates are expensive. The more pages required, the higher the installation cost for printing.

Other types of plates

In screen printing, the process commonly used to print on fabric, the screen is equivalent to the printing screen. It can be created manually or photochemically and is usually a porous fabric or stainless steel mesh stretched over a frame. Paper plates are usually only for short prints without close-up colors or touches that require trapping. they are proper. Plan your layout to use paper pages efficiently if you want to save money. Not all commercial printers offer this budget option.

The rise of digital printing

No printed pages are used in the digital printing process. It requires a different type of printer and is ideal for short runs, quick turnarounds, cost-effective short runs, and custom variable data printing. Not all commercial printing companies have both offset and digital printing machines.

What are printed pages and how are they made?

Understanding the print production process, once you’ve sent us your PDF artwork, can be very helpful in planning some of the design elements to contribute to a quality print result. One such process is separating your final artwork into CMYK, and any spot colors, to create printing plates.

What happens to the pages after a print project is finished?

Fortunately, printing plates are made from the purest form of aluminum, and since they are not used for long periods of time or have complex shapes, they are infinitely recyclable. Commercial printers around the world have been recycling their printing plates for years, contributing to the chain economy.
