Offset vs Digital Printing

The printing trade has evolved tremendously over the past 30 years and with that has come a lot of technological innovation. For hundreds of years offset printing was the standard, but as new technology became available we saw the emergence of digital printing which has dominated in the print space.

But what is the difference between offset printing and digital printing?

We share the answer to that question as well as other helpful information.

What is the Difference Between Offset Printing & Digital Printing

While there are some similarities between offset & digital printing there are some very distinct differences that we are going to call out here.

Printing Technique

Offset Printing: In offset printing, the ink is transferred from metal plates to a rubber blanket and then onto the printing surface, usually paper. It involves a process of indirect printing where the inked image is offset or transferred onto the paper.

Digital Printing: Digital printing involves the direct transfer of digital files onto the printing substrate using specialized printers. It does not require the use of printing plates or intermediate surfaces like rubber blankets.

Setup Process

Offset Printing: Offset printing requires extensive setup time and preparation. It involves creating printing plates, adjusting ink and water levels, and fine-tuning the press to achieve optimal print quality. The setup process can be time-consuming and is more suitable for large print runs.

Digital Printing: Digital printing eliminates the need for plate setup and complex adjustments. The digital file is directly sent to the printer, significantly reducing setup time. Digital printing is ideal for short print runs or on-demand printing due to its quick setup process.

Print Quality

Offset Printing: Offset printing is known for its high print quality, particularly for large print quantities. It offers sharp and detailed images with precise color reproduction, making it suitable for projects that require fine details, gradients, or complex color tones.

Digital Printing: Digital printing has advanced significantly and can now achieve excellent print quality. While it may not match the exact level of detail and color accuracy as offset printing for large runs, it still produces high-quality prints with sharp images and vibrant colors. Digital printing is particularly well-suited for short to medium print quantities.

Costs

Offset Printing: Offset printing is generally more cost-effective for large print quantities due to its lower cost per unit. The setup costs, including plate creation and press setup, are spread over a higher number of prints, reducing the overall cost per piece.

Digital Printing: Digital printing is cost-effective for short print runs or personalized printing because it eliminates the need for expensive plate setup. It offers cost advantages for smaller quantities, as there are no upfront plate costs, making it more suitable for on-demand or variable data printing.

Customization and Variable Data Printing (VDP)

Offset Printing: Offset printing does not readily support customization or variable data printing. Each print in a large run generally contains the same content and design, with limited room for personalization.

Digital Printing: Digital printing excels in customization and variable data printing capabilities. Each print can be personalized with unique text, images, or other content, allowing for targeted marketing, personalized packaging, or individualized materials.

Turnaround Time

Offset Printing: Offset printing may have a longer turnaround time due to the setup process and drying time required for the ink. Large print runs can take more time to complete, although the actual printing process is faster once the setup is done.

Digital Printing: Digital printing offers a quick turnaround time, as it does not require extensive setup or drying time. Prints can be produced rapidly, making digital printing ideal for projects with tight deadlines or short production timelines.

What is Offset Printing?

Offset printing, also known as offset lithography, is a commonly used printing technique for producing high-quality printed materials, such as newspapers, magazines, brochures, books, and packaging materials. It is called “offset” because the ink is not directly transferred from the printing plate to the paper but instead passes through an intermediate surface called a rubber blanket before reaching the paper.

The offset printing process involves several steps:

Prepress – This stage involves preparing the artwork or design for printing. It includes tasks like typesetting, image processing, color separation, and creating printing plates.

Plate making – The design is transferred onto metal plates (usually aluminum) through a photographic process. These plates have ink-receptive and ink-repellent areas corresponding to the image and non-image areas of the design.

Ink application – The printing plates are mounted onto cylinders on the printing press. The first cylinder applies ink to the plates, and the ink adheres only to the image areas.

Offset and transfer – The inked image is transferred from the plates to a rubber blanket cylinder. The rubber blanket cylinder receives the inked image from the plate cylinder and then transfers it to the paper, which passes between the blanket cylinder and a pressure cylinder. The rubber blanket acts as an intermediary, allowing the image to be offset or transferred onto the paper.

Drying and finishing – After the paper receives the inked image, it passes through a series of rollers to dry the ink and set it on the paper. Various finishing processes such as cutting, folding, and binding may be performed to complete the printed materials.

Advantages of Offset Printing

When it comes to offset printing you’ll find that there are quite a few advantages over other printing methods. We’ve outlined a number of the most prominent offset printing advantages here.

  • High Quality
