Quick definition: Lithography is a way of printing that uses a flat surface to transfer images or text onto materials. It is used to print for art but has grown into offset lithography, which is now one of the most popular ways to do commercial printing.
Ever wondered how fine art prints achieve their intricate beauty? Litho printing is one way that artists create high-quality prints with amazing detail. It’s a method that has been used for centuries, combining art and science in a fascinating process.
Nowadays, lithography printing is a dominant technology in the commercial printing sector, accounting for a significant share of the market.
As of 2023, lithography held approximately 43.92% of the commercial printing market share, and projections indicate that this figure will remain around 44.1% in 2024
In this article, we’ll dive into what lithography is, how it works, and why it’s still a key technique in both art and technology today.
The Stone Lithography Print Method
Lithography was invented by Alois Senefelder in the late 18th century.
He stumbled upon the principle of lithography by accident, while trying to find a cost-effective way to reproduce his writings.
The original stone print involves using a greasy medium (such as crayon or tusche) create an image on on a slab of limestone.
Compared to other printmaking technique, like etching or block printing, which require acid or carving tools to cut into the surface, this is simpler and more efficient.
Senefelder’s discovery was revolutionary, and soon, this way of printmaking spread across Europe, changing the way artists and printers reproduced images.
The Principle
Lithography is based on a simple principle — grease and water don’t mix. When drawing on a stone or metal plate with a greasy substance like pencil or crayon, the image area becomes oily, while the non-image areas repel the ink. This makes it possible to transfer the design onto paper, creating high-quality reproductions of artwork.
The word “lithography” is derived from the Greek words for stone (lithos) and writing (graphia). The process uses a greasy technique to create an image on a smooth surface, typically limestone, or today, metal plates.
Transition to Offset Lithography Process
It evolved over time, and the modern version of the process—offset lithography—emerged as a game-changer.
In the advance offset printing, the ink is first transferred to a rubber blanket roller before being printed on the paper.
This allows for high-volume, high-quality prints, making it the most common print method used in large-scale commercial printing today.
Aluminum plates are now commonly used, thanks to their durability and cost-effectiveness.
The Lithography Printing Process
Creation of the Design
The first step in lithography involves drawing or engraving a design onto print plate. Traditionally, this was done on a slab of limestone, nowadays aluminum is commly used.
Applying Ink
Once the design is created, the plate is coated with a special oil-based ink. The greasy medium on the plate holds onto the ink, while the non-image areas are treated with gum arabic and water to keep them ink-free.
Printing the Design
The plate is then pressed against a sheet of paper or other printing surface. The result is a precise print that can reproduce the original piece of artwork.
Chemical and Colour
Litho prints often use multiple print sheets to apply different colours, creating vivid, full-colour images. The addition of multiple layers of ink allows the printer to achieve intricate colour gradients and subtle hues that make the artwork pop.
Lithography in Art and Technology
Lithographic Artwork and Famous Artists
This printing mechod was quickly adopted by artists who appreciated its ability to reproduce artwork with fine details and rich textures. Artists like Henri Toulouse-Lautrec, Pablo Picasso, and Marc Chagall created some of their most famous pieces using lithography. Their works, often created on stone or metal slabs, showcased the versatility and precision of this technique.
Litho printing has always been highly valued for its ability to reproduce art in large quantities while maintaining the integrity of the original work. Today, you can find these prints in galleries and online marketplaces, where they are often sought after by collectors who value their craftsmanship and historical significance.
Technological and Modern Applications
Did you know lithography isn’t just used for art? It’s also a key technology in modern industries like semiconductor manufacturing and 3D printing.
Lithographic methods have been adapted for creating detailed, microscopic images on chips and components used in electronics.
Whether you’re making a high-volume run of printed materials or developing cutting-edge technology, lithography is still essential in the modern world.
Practical Guide for Beginners
Essential Tools and Materials
If you’re interested in diving into the world of it, here’s a list of the essentials:
- Print plates
- Greasy medium, such as crayon or Tusche.
- Oil-based ink for printing.
- Water and gum arabic to treat non-artwork zones.
- A press to transfer the image.
Creating Your First Lithographic Print
Here’s a quick guide to creating your first lithograph:
- Prepare your plate: Treat a stone or aluminum plate with the greasy medium (like a pencil or crayon).
- Apply ink: Use oil-based ink to coat the artwork zones.
- Transfer the image: Place the plate on a blank sheet of paper and run it through a press to transfer the image.
