Printing technology has come a long way since the first printing press was invented in the 15th century. Nowadays, there are countless ways to print documents and images, from digital printing to screen printing and everything in between. But one printing method that has stood the test of time is litho printing.
Litho printing is a versatile and highly effective printing method that has revolutionised the printing industry. In this article, we’ll explore what litho printing is, how it works, and why it’s such an important printing method.
What is Litho?
This a printing method that uses a flat plate to transfer an image or text onto paper or other materials. The plate is made of a flat, smooth surface, usually metal, with the image etched into it using chemicals. The plate is then inked, and the inked image is transferred onto a rubber roller that transfers the image onto paper or other material.
Litho printing is widely used for a range of printing jobs, from newspapers and magazines to packaging and promotional materials. It’s also a popular choice for fine art prints, due to its ability to reproduce detailed images with great accuracy.
How Does Litho Printing Work?
Litho printing works on the principle of repulsion between water and ink. The flat plate used in litho printing is made up of two layers. A base layer, usually made of aluminium, and a photosensitive layer made of a photosensitive material. The photosensitive layer is coated onto the aluminium base and then exposed to light through a negative image of the design.
The exposed areas of the photosensitive layer harden, while the unexposed areas remain soft. The plate is then washed with a solution of water and gum arabic, which sticks to the unexposed areas and repels the ink that is applied later on. The exposed areas of the plate attract the ink, which is transferred onto the paper or other material.
Once the plate is ready, it’s attached to a printing press. The plate is inked with a roller, and then the inked image is transferred onto a rubber roller, which then transfers the image onto the paper or other material. The rubber roller helps to ensure a consistent, even application of ink across the paper or material.
Why is Litho Important?
Litho printing is a highly effective printing method that offers a range of benefits over other printing methods. One of the main benefits of litho printing is its ability to produce high-quality prints with great accuracy and detail. Because the images are etched into the plate using chemicals, litho printing can reproduce even the most intricate designs with stunning clarity.
Litho printing is also incredibly versatile. It can be used to print on a wide range of materials, from paper and cardboard to metal and plastic. This makes it an ideal choice for a range of printing jobs, from packaging and labels to promotional materials and fine art prints.
Another key advantage of litho printing is its ability to print large volumes of prints quickly and efficiently. Because the plate only needs to be etched once, litho printing can produce large quantities of prints with minimal setup time. This makes it an ideal choice for printing newspapers, magazines, and other mass-produced items.
Finally, litho printing is also cost-effective, particularly for large print runs. Because the printing plates can be reused many times, litho printing is a more cost-effective option for large print runs than other printing methods.
Technical requirements for artwork when preparing for litho printing:
- Colour: Use CMYK color mode, not RGB.
- Resolution: Maintain a high resolution of at least 300 DPI.
- Bleed: Extend artwork beyond the trim edge by 3mm.
- Text Safe Area: Keep vital content 5mm from the trim edge.
- File Format: Use Adobe PDF.
- Fonts: Embed or outline fonts.
- Colour Profiles: Use standard CMYK profiles.
- Spot Colors: Properly define and communicate spot colours.
- Image Compression: Minimise image compression.
- Proofing: Order a proof before production.
- Correct Size: Ensure artwork matches the print dimensions.
- File Pre-Flight: Check for technical issues.
- Vector Graphics: Use vectors for logos and text.
