The art world is filled with reproductions and copies, and it can be challenging to distinguish an original painting from a fake. However, there are several ways to authenticate a painting. One of the most common methods is to examine the surface of the painting closely, often with a magnifying glass or high-quality phone camera. Real paintings usually have individual brush strokes that can be seen or felt, although some artists, like Renaissance masters, use thin layers of paint to create a smooth lacquer surface. Another technique is to hold the painting up to the light and observe if light passes through the back of the canvas, which indicates varying degrees of impasto, or paint heaviness, in an original work. Other signs of authenticity include the age of the painting, the material used, and the artist's signature and stylistic patterns.

Brush strokes: real paintings have individual brush strokes that can be seen or felt
When it comes to distinguishing a true painting from a copy, one of the key things to look out for is the presence of individual brush strokes. Real paintings often have distinct brush strokes that can be seen or felt, adding texture and depth to the artwork. Here are some things to consider when examining brush strokes:
Firstly, the type of paint used plays a significant role in determining the visibility and feel of brush strokes. Oil and acrylic paintings, for instance, tend to have physically raised brush strokes that create a textured surface. Running your finger gently over an oil or acrylic painting should allow you to feel the raised paint and the individual brush strokes. On the other hand, watercolour and gouache paintings typically do not have raised brush strokes, resulting in a smoother surface.
Secondly, the artistic style and technique of the painter can also impact the appearance of brush strokes. Some artists, like the Impressionists and Post-Impressionists (e.g., Monet, Van Gogh, and Gaugin), are known for their visible and expressive brush strokes that contribute to the overall style and character of their paintings. These artists often applied paint in a way that emphasised the movement and texture of their brushwork. In contrast, other artists may intentionally aim to minimise the appearance of brush strokes by using thin layers of translucent pigments and glazes, creating a smoother and more blended effect. Renaissance artists like Leonardo da Vinci and Peter Paul Rubens are known for this technique, where the paint is applied in a way that obscures the individual brush strokes, resulting in a more uniform surface.
Additionally, examining the painting under magnification can reveal further details about the brush strokes. Watercolour paintings, for example, often show brush impressions under magnification, with overlapping paint colours. Copies, on the other hand, tend to have a flatter and smoother appearance, lacking the texture and depth of original brush strokes.
It's important to note that reproductions and copies have become increasingly sophisticated, and some may even attempt to mimic brush strokes to deceive the observer. However, these fake brush strokes often lack the subtleties and unique characteristics of genuine brushwork. In recent years, the development of artificial intelligence (AI) tools has offered new ways to analyse and distinguish brush strokes, even at the brush bristle level, aiding in the identification of original creators and the detection of forgeries.

Canvas texture: a giclée will have a uniform canvas texture, whereas a painting will have swirls, skips, buildups, and brushstrokes
One of the ways to distinguish a true painting from a copy is by examining the canvas texture. A giclée, or high-quality print, will have a uniform canvas texture, whereas a painting will have a more varied texture with distinctive marks such as swirls, skips, buildups, and brushstrokes.
Giclée prints are created using digital scanning technology that captures the artwork at a very high resolution. This results in a uniform texture on the canvas, giving the appearance that the colours are embedded into the canvas rather than resting on its surface. In contrast, paintings often exhibit visible and tactile brushstrokes, especially those by Impressionist and Post-Impressionist artists like Monet, Van Gogh, and Gauguin. Van Gogh, for example, is known for his distinctive swirling brushstrokes, which he adopted during his stay at the mental hospital of Saint-Rémy.
To identify whether a work is a giclée or a painting, you can run your hand along the surface. If the paint is layered and still resting on the surface, it is likely an original painting. On the other hand, if it feels like the art has seeped into the canvas, creating a smooth and uniform texture, it is likely a giclée print. Additionally, examining the sides of the canvas can provide clues. If there is a clean, straight boundary around the image that doesn't extend to the edges, it is likely a print rather than a painting.
It is worth noting that some artists hand-embellish, sign, and number their giclée prints, making them more challenging to distinguish from paintings. In such cases, the presence of large printed areas or inconsistencies in the texture throughout the print may offer hints that it is a giclée.
While the canvas texture is an important indicator, it should not be the sole method of distinguishing a true painting from a copy. Other factors, such as the presence of a signature, edition number, or dot pattern under magnification, can also provide valuable insights when appraising a work of art.

Age: an old painting will have an aged essence to its frame, canvas, and paint
The age of a painting can be a crucial factor in distinguishing an original work of art from a copy. Here are some ways through which the age of a painting can be determined:
Canvas Examination
The canvas of a painting can provide valuable insights into its age. Examining the back of a painting can reveal clues such as stamps, labels, or stretcher bars that indicate the supplier of the materials. This information can help identify the painting's country of origin and place it within a specific time period. Additionally, the design of canvas stretchers has evolved over time, so the style of the stretcher can offer hints about the painting's era. For example, older paintings may have handmade wooden dowels or old hand-wrought nails.
Paint Analysis
Analysing the paint itself can also help determine the age of a painting. Oil paintings, for instance, often exhibit raised paint, creating a textured surface. However, it's important to note that some paintings may have a flat paint layer, especially if they have been relined or conserved using modern techniques. Examining the paint under magnification can reveal the presence of tiny coloured dots, which are indicative of mechanical or digital reproductions, especially if they are arranged in a regular pattern. Older reproductions may show dots in an irregular pattern, while antique reproductions like engravings may not have any dots at all.
Signs of Ageing
The overall appearance of a painting can also suggest its age. Old paintings may exhibit signs of ageing, such as craquelure—a fine pattern of cracks that form on the surface of the paint over time. While varnish can make it more challenging to spot craquelure, artificial ageing techniques can also be employed, so expert opinion is valuable in such cases.
Relining and Conservation
Relining is a conservation technique where an older canvas is attached to a newer one to preserve the painting. This practice was common in the 19th century, so if a painting appears older at the back than it actually is, relining may be a reason. Conservators often reuse the stretcher bars and nails from the original canvas, providing additional clues about the painting's history. However, forgers may also attach their copies to older canvases to deceive experts, so other factors must be considered.
Artistic Techniques
The artistic techniques used in a painting can also offer hints about its age. For example, some artists, such as Renaissance masters, employed countless layers of thin, translucent pigments and glazes to create subtle variations in colour and tone, resulting in a smooth lacquer-like surface. This technique contrasts with the visible brushstrokes favoured by Impressionist and Post-Impressionist artists.

Signature: a true signed print will have a hand-rendered signature by the artist, usually in the margin
Artists' signatures are an important part of their paintings, serving as a calling card and claiming ownership. Signatures also add value and mark the painting as a complete, sellable piece. A true signed print will have a hand-rendered signature by the artist, usually in the margin, which may be in the form of a distinctive mark or even a stamp. This is in contrast to prints, which may display the artist's signature as part of the printed artwork but are not considered signed prints.
The placement of the signature can vary, with some artists choosing to sign in the bottom right or left-hand corner, a few centimetres up from the bottom edge, or even vertically along the right-hand edge to avoid being covered by the frame. Some artists, like Titian, sign their paintings in remarkable places, such as in the neckline of the female figure in "Bacchanal of the Adrians". Others, like Chardin, integrate their signatures into the composition, using light touches of white to create the effect of an engraving in the stone.
It is important for artists to establish a clear and consistent signature format, typically using their first name, last name, or initials. Signatures can be created using different tools, such as scratching into wet paint with a paintbrush or pencil, or using a charcoal or pastel pencil for dark or light foregrounds, respectively. Artists should consider the composition, style, and placement of their signature to ensure it complements the rest of the painting without being jarring.
In addition to the signature, other factors can help distinguish a true painting from a copy. These include examining the surface for individual brushstrokes or swirls, buildups, or textures indicative of real paint. Analyzing the canvas or materials used, as well as studying the artist's oeuvre for stylistic patterns and colour usage, can also aid in authentication.

Dots: often, prints are made up of tiny coloured dots that can be seen with a magnifying glass
One of the most common ways to distinguish a true painting from a copy is to examine the artwork closely, often with the help of a magnifying glass. In many cases, prints are made up of tiny coloured dots that can be seen with a magnifying glass. These dots are arranged in a repeating pattern throughout the painting.
When examining a painting, a magnifying glass can help reveal the presence of these tiny dots, indicating a printed reproduction rather than an original painting. This technique is particularly useful for identifying photomechanical reproductions, which are often characterised by a distinct dot pattern.
It is worth noting that not all reproductions have visible dots. For example, Giclée prints, which are high-quality machine-made reproductions, have extremely small pixels of colour with no perceptible dot pattern. Giclée prints may even be hand-embellished by the artist, making them more challenging to distinguish from original paintings. However, Giclée prints typically have a uniform canvas texture, lacking the telltale brushstrokes or paint textures found in original paintings.
To further complicate the matter, some artists create hand-embellished Giclée prints, adding dabs of paint to simulate the impasto technique, which involves building up thick layers of paint to create a three-dimensional effect. In such cases, the use of a magnifying glass to detect coloured dots may not be effective, and other methods of authentication should be considered.
In summary, examining a painting with a magnifying glass to look for tiny coloured dots can be a helpful first step in distinguishing a true painting from a copy. However, it is important to recognise that advancements in reproduction technology have resulted in more sophisticated printing methods that may not exhibit visible dot patterns. Therefore, it is advisable to employ multiple techniques and seek expert advice when assessing the authenticity of a painting.

Frequently asked questions
One of the best ways to spot a print is to use a magnifying glass or a high-quality camera on your phone. If it's a print, you'll likely see tiny dots in a repeating pattern. If it's an original, you may be able to see brushstrokes and varying textures. Originals may also have a rough surface when viewed from an angle, whereas reproductions tend to have a flat and even surface.
A giclée is a high-quality machine-made reproduction, often made from a photograph. It will have a uniform canvas texture and no brushstrokes. However, some artists hand-embellish giclées, making them harder to distinguish from originals.
Originals will usually have brush bristles and signs of ageing. You can also check the canvas for the artist's signature, the edition number, and the original stretcher. If it's a limited-edition print, it may have a stock identification number on the back.
Familiarise yourself with the artist's work and the colours available when the painting was made. Be cautious of cheap prices, but don't assume that expensive means original.
