Offset Printing Inks

What is the difference between digital and offset printing?

Digital printing is a direct printing method where digital images are printed directly onto the paper or material. It's ideal for small runs and personalizing designs. In contrast, offset printing involves transferring (or "offsetting") ink from plates to a rubber blanket and then to the printing surface. This technique is ideal for high-quality prints and cost-effectiveness in large volumes.

Why is offset called offset?

Offset printing is named as such because the ink is not transferred directly onto the paper. Instead, the inked image is transferred (or offset) from a plate to a rubber blanket and then to the printing surface. This indirect approach contributes to the high-quality outcome.

What is the offset printing process?

• Plate Making: An image is burned onto a plate with a laser.

• Inking: The plate is inked, only transferring ink to the image areas.

• Offsetting: The inked image is transferred to a rubber blanket.

• Printing: The image is then pressed from the blanket onto the paper.

What are the types of Offset Printing?

• Sheet-fed Offset Printing: Uses individual sheets of paper, suitable for small to medium-sized jobs.

• Web Offset Printing: Uses large rolls of paper and is ideal for high-volume publications like newspapers.

How long does offset printing take to dry?

The drying time for offset printing can vary but typically ranges from a few hours to several days, depending on the ink and paper type.

What is the maximum size for offset printing?

The maximum size is generally determined by the press size. Large format offset presses can handle sheets up to 40 inches wide or more, suitable for large posters or maps.

How to choose between offset and digital printing?

• Volume: Offset is more cost-effective for large runs.

• Quality: Offset offers superior image quality.

• Customization: Digital allows for easy customization.

How big is the quality difference between offset and digital printing?

The quality of offset printing is generally superior, especially for images and fine details, due to its precise control over ink and water balance.

Can offset printing be used for small print runs?

Traditionally, offset printing is less economical for small runs due to the setup costs. However, it proves to be cost-effective for medium to large runs.

What kind of materials can be printed with offset printing?

Offset printing can accommodate a wide range of materials, including paper, cardstock, plastic, and metal sheets.

Are there any color limitations with offset printing?

While offset printing can produce a wide spectrum of colors using the CMYK color model, it might require extra runs for special colors, potentially increasing costs.

Is offset printing environmentally friendly?

Offset printing can be environmentally friendly, especially when using soy-based inks and recycled materials. However, it depends on the practices of the printing company.

Can I use offset printing for custom-sized projects?

The turnaround for an offset printing project can vary from a few days to a couple of weeks, depending on the complexity and volume of the job.
