Scanning is a valuable tool for artists and creatives who want to preserve their artwork and create digital archives. It is also useful for those who want to practice painting without risking the original drawing. Before scanning a painted piece of art, it is important to ensure the paper is free from wrinkles, tears, or staples. The artist should also consider whether scanning or photographing the artwork is a better option, depending on the characteristics of the piece. For example, scanning can capture minute details such as the texture of the paper, but it may create reflections on glossy surfaces.

Scanning vs. photographing artwork
Scanning and photographing are both excellent methods for reproducing artwork, each with its own set of advantages and disadvantages. The choice between the two ultimately depends on the characteristics of the artwork and the desired outcome.
Scanning offers several benefits, such as the ability to capture intricate details, including the texture of the paper or the fibres on a canvas. It provides an extremely accurate reproduction and allows for better control over the final output's resolution. Scanning is also advantageous for artworks without glossy or three-dimensional elements, as it minimizes issues with glare and reflections. Additionally, scanning does not require bulky camera equipment and often necessitates fewer colour correction measures due to improper lighting.
On the other hand, photographing artwork is preferable for pieces with glossy surfaces or three-dimensional elements. Oil and acrylic paintings, for instance, often have a glossy finish that can create unwanted reflections during scanning. By using specialized lighting setups, such as polarized lighting, photographers can minimize glare and reflections. Photographing artwork is also more suitable for larger pieces that may not fit into a scanner and allows for easier reproduction of large paintings without the need for a large format scanner.
It is worth noting that both methods require careful inspection of the digital files to ensure accurate colour representation and details. Printing a test copy before a full print run can help verify if adjustments are needed to achieve the desired results.
While scanning provides more control over resolution, photographing artwork requires specialized photography skills and equipment, including a tripod, camera, sharp lens, and lighting setup. It is essential to consider the level of skill and equipment accessibility when deciding between scanning and photographing artwork.

Preparing artwork for scanning
Firstly, consider the size of your artwork. Most scanners can only accommodate sizes up to 16"x24", so if your artwork is larger, you may need to use a different method, such as photographing the artwork or using a larger scanner. If you need to take a photo, consider renting a professional camera to ensure the best quality.
Next, ensure your artwork is suitable for scanning. Scanning works best for pieces with minimal texture, like thick globs of paint. If your artwork has a glossy finish, it may be better to photograph it, as scanning can create reflections. However, if you do choose to scan a glossy piece, you can minimize glare by using specialized lighting setups, such as polarized lighting.
Before scanning, always check your scanner's glass for dust or paint residue, as these will show up in your scan. It is also important to choose the correct DPI (dots per inch) or resolution for your scan. A minimum of 300 DPI is recommended, but you can increase this to 600 or even 1200 DPI if you want to scale up your artwork without losing quality. Remember, the higher the DPI, the larger the file size.
Finally, before doing a full print run, always print a test copy to ensure the colors and details are accurate. Adjust your digital file if necessary to achieve the desired result.

Adjusting brightness and contrast
Adjusting the brightness and contrast of a scan is an important step in ensuring that the colours and details of your painted paper are accurately represented in the digital file. This is especially important when scanning artwork, as you want to capture the minute details, such as the texture of the paper and the fibres of the canvas.
There are several ways to adjust the brightness and contrast of your scan. One standard method is to use the Curve Tool or the histogram tool, which is available in Photoshop under "Levels". The histogram tool is preferred as it is easier to use and does not risk upsetting the colour balance as much. The Curve Tool or histogram can be used to adjust the gamma or mid-range brightness.
Another way to adjust brightness is by sliding the Grey Midpoint to the left, which will lighten the image's midrange tones. This is a good way to adjust the overall image brightness, as the mid-tones are typically the most important part of the image.
Additionally, you can adjust the brightness and contrast settings directly on your scanner. This can be done by accessing the Configuration tab of the Administration module, selecting the appropriate scanner, and then adjusting the brightness and contrast sliders to your desired levels. Moving the slider to the left will decrease the brightness or contrast, while moving it to the right will increase it.
It is recommended to make these adjustments during the scanning process, as the scanner's curve is adjusted before the gamma conversion, preserving shadow detail and resulting in less loss of data. You can also select Photo mode on your scanner, which will help avoid issues with differing background colours on the page, although this may negatively affect character recognition. Alternatively, you can select Auto Brightness and Auto Contrast to have these settings automatically adjusted.
Finally, it is always a good idea to print a test copy before doing a full print run to ensure that the colours and details of your painted paper are accurately represented in the scan.

Selecting scan settings
Selecting the right scan settings is crucial to achieving the desired output quality. Here are some detailed instructions on how to select the appropriate scan settings:
First, decide on the file type you want to save your scanned document as. Common choices include PDF, JPEG, and PNG. The file type will determine the subsequent file destination and available scan settings. For instance, if you are scanning a document with text, you may prefer a PDF file, which supports optical character recognition (OCR) and allows you to search and select text in the scanned output.
Next, select the save location for your scanned document. You can save it on your computer's hard drive, a USB storage device, or cloud storage services like Google Drive. If you choose to save it on a USB device, ensure it is inserted into the USB port on the printer or scanner.
Now, place the document on the scanner. If using the scanner glass, place the side you want to scan facing down. Use any arrow markings on the glass to align your document correctly. If your scanner has an automatic document feeder, you can use it to scan multiple pages without manually replacing each one.
Adjust the scan settings to meet your requirements. These settings may include resolution, brightness, contrast, and colour mode. Play around with these settings to get the desired output. For instance, if your artwork has intricate line work or subtle textures, ensure the scanner is set to scan from a very short distance, so every part of the piece is in focus. If your artwork has a glossy finish, you may want to consider photographing it instead of scanning it to avoid reflections.
Finally, preview the scan before finalising it. Check if the margins, page size, and other formatting options are as desired. Make any necessary adjustments and re-scan the document until you are satisfied with the output.

Frequently asked questions
Yes, you can run paper with paint through a scanner. Scanning is a good way to reproduce your artwork and can even capture minute details like the texture of the paper.
First, ensure the document is free from wrinkles, tears, or staples. Then, place the document face-down on the scanner bed or in the document feeder, depending on your printer's design. Next, navigate to the scanning option on your printer's control panel or touchscreen interface. This may be labelled "Scan", "Scan to Computer", or something similar. Finally, choose your preferred scanning settings, such as colour mode, resolution, and file format.
Scanning can capture more detail than photography, with a higher resolution. Photography is better for larger pieces of art that do not fit in a scanner or have 3D elements.
